How Much Does a BSA or BSPCE Valuation Cost? Fees 2026 (France)

2026 price ranges to value BSA, BSPCE, BSA-AIR and stock options in France.

Introduction: how much does a BSA or BSPCE valuation really cost in France in 2026?

In France, a valuation of a single BSA, BSPCE, stock option, share-with-warrant (ABSA), bond redeemable in shares (ORA) or bond-with-warrant (OBSA) generally costs between EUR 3,000 and 6,000, and a management package combining several instruments or several share classes between EUR 6,000 and 12,000 (Hectelion's 2026 practice).

The right budget depends first on the number of instruments and beneficiaries, before the size of the company itself.

French law distinguishes several equity-incentive instruments specific to its companies: BSPCE, reserved for young companies within the meaning of article 163 bis G of the French Tax Code, BSA warrants, open to any subscriber, the BSA-AIR, and historical stock options. This article focuses on these instruments; free shares (AGA), ABSA, ORA and OBSA, more common in LBOs and financial structuring, are covered in a dedicated article, and their Swiss equivalent in a third article.

"Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.", IFRS 13, definition of fair value.

Three reasons make this budget particularly topical in 2026.

First, the spread of management packages combining BSPCE, AGA and BSA in a single fundraising or LBO transaction multiplies the number of instruments to value separately for the same beneficiary.

Second, tighter scrutiny by the French tax authorities and URSSAF over the actual eligibility of BSPCE-issuing companies, and over the economic reality of the strike price set at grant, raises the bar for report defensibility.

Third, the growing sophistication of management packages combining several share classes, with liquidation preference and ratchet clauses, increasingly requires binomial or Monte Carlo models, more expensive than a simple Black-Scholes.

This article gives prices at a glance, details the BSPCE eligibility criteria, compares BSA, BSPCE, AGA and stock options, explains what drives the bill, situates 2026 trends, describes the course of an engagement, compares providers, explains how to reduce cost, lists the five costliest mistakes, then illustrates it all with two priced cases, before answering the most frequent questions.

The price of a BSA or BSPCE valuation at a glance: 2026 ranges

Instrument	Model / complexity	Price range	Indicative timeline
Single BSA	Single instrument, Black-Scholes method	EUR 3,000 to 6,000	2 to 4 weeks
Single-class BSPCE	Black-Scholes, optional 409A report (+ EUR 1,000)	EUR 3,000 to 6,000	2 to 4 weeks
Stock options	Black-Scholes, historical regime	EUR 3,000 to 6,000	2 to 4 weeks
Multi-instrument management package	Several instruments or classes, several beneficiaries	EUR 6,000 to 12,000	3 to 6 weeks

Ranges observed by Hectelion in 2026 for engagements in France, excluding additional financial due diligence. The valuation model required, more than the size of the company alone, drives most of the price spread.

What is a BSA for? When and why to use one

A BSA gives its holder the right, but not the obligation, to subscribe new shares at a price and within a timeframe set in advance. Unlike the BSPCE, it is not reserved for employees: it is the instrument of choice for bringing an outside party into the company, without immediately granting voting rights or diluting the capital before the right is exercised.

In practice, the BSA serves three main purposes. First, to compensate a business angel, an advisor or a strategic partner without any cash outlay: the beneficiary neither invests nor receives anything immediately, but benefits from a valuation increase if the BSA is exercised later. Second, to structure a bridge round or a bond with warrants (OBSA), where the BSA compensates the lender's risk by offering deferred access to the capital without giving up repayment of the debt. Third, to align a minority investor's interest with the company's future performance, notably in an LBO where BSA are often attached to the ordinary shares subscribed by management, in the form of a share with subscription warrant (ABSA).

The BSA is, however, not suited to an employee seeking a tax advantage: the gain on disposal of a BSA falls under the ordinary capital gains regime, without the tax relief specific to the BSPCE.

What is a BSPCE for? When and why to use one

The BSPCE addresses a specific problem: how can a young company with tight cash attract and retain senior employees and executives without matching market salaries? By granting the right to subscribe shares at a price fixed in advance, often set at a discount to the current valuation, the BSPCE turns part of the compensation into a bet on future value creation, with no immediate cash outflow for the company.

The typical use case: a seed or Series A startup hires a CTO or a head of sales below market salary, compensated with a BSPCE plan representing, for example, 0.5% to 2% of the capital, with vesting over three to four years and a one-year cliff. Unlike an AGA, the beneficiary must exercise the right and pay the strike price to become a shareholder, which limits the accounting cost of the grant in the event of early departure.

The BSPCE does not, however, suit every situation: beyond the company's eligibility condition, a founder wishing to bring in a non-employee outside investor should turn to a classic BSA, and a company that prefers a strong signal with no risk of non-exercise should opt for an AGA instead.

What is a BSA-AIR for? When and why to use one

The BSA-AIR is the French contractual adaptation of the American SAFE: an investor puts in funds immediately, without the parties having to set a valuation at that exact moment. Conversion into shares happens at the next financing round, at that round's price, generally with a discount and sometimes a valuation cap negotiated at signing.

Its typical use case: a very early-stage startup needs a few tens to a few hundred thousand euros to hold out until its next raise, without wanting to tie up several weeks negotiating a full priced round. The BSA-AIR allows cash to be collected within days, with the valuation deferred and objectified by the market at the next round rather than set arbitrarily too early.

For free shares (AGA), ABSA, ORA and OBSA, instruments more common in LBOs and financial structuring than in fundraising, a dedicated article details their pricing and uses: How much does an AGA, ABSA, ORA or OBSA valuation cost?

Scope your valuation budget before you commit

Thirty minutes is enough to scope the perimeter of the instruments to be valued and the corresponding budget. Hectelion carries out financial instrument valuation engagements for French companies, BSA, BSPCE or BSA-AIR, alone or in support of your auditor. Book a free, confidential conversation with our team: we scope the number of instruments, the appropriate model, and the timeline, before any commitment.

Acontos: get a free online estimate of your company's value

Before going into the budget in detail, know that Hectelion has developed Acontos, an online audit, due diligence and business valuation tool, powered by Anthropic's Claude Sonnet 5 artificial intelligence and calibrated on Hectelion's methodology. From your accounts, it produces a first estimate of your shares' value within minutes, free of charge and without retaining any document.

A BSA, a BSPCE or an AGA is always valued by reference to the value of the underlying ordinary shares, so launch the valuation simulator to get a first order of magnitude, then keep reading to understand what a valuation engagement costs, and what it covers.

BSPCE: the eligibility criteria of article 163 bis G of the French Tax Code

Before even talking about price, the issuing company still needs to be eligible for the BSPCE regime, a check many executives skip and that the tax authorities never skip. Article 163 bis G of the French Tax Code reserves this scheme for joint-stock companies incorporated for less than fifteen years, subject to French corporate income tax, whose shares are not admitted to trading on a regulated market, or, if they are, on a market whose capitalization stays under a threshold set by decree.

The company must also be held, directly or indirectly, to at least 25% of its capital by individuals, or by legal entities themselves majority-held by individuals, a condition that effectively excludes certain group subsidiaries or structures majority-held by institutional funds. A company that loses its eligibility during its life, for example after a financing round that brings in a non-eligible reference shareholder, can no longer issue new BSPCE, without calling into question the BSPCE already granted.

These criteria, to be checked with your advisor before any grant, directly shape the choice of instrument: a company not eligible for BSPCE turns to AGA, BSA or classic stock options, each with its own tax and social security regime.

What discount should apply to a BSPCE's strike price?

Administrative doctrine frames a BSPCE's strike price without setting a numerical discount: BOFiP requires this price to be at least equal to the value of the shares at the date the warrants are issued, failing which the benefit is exposed to requalification as salary. The question is therefore not "what discount to apply" in the sense of an authorized allowance, but "what is the real fair value of the ordinary shares" at that date.

This value almost always differs from the per-share price shown at the last financing round, because that price compensates preferred shares, carrying a liquidation preference and sometimes a ratchet, while the BSPCE covers ordinary shares without these protections. The gap between the two is not calculated with a flat allowance, but through an allocation of enterprise value across the cap table's share classes, the same option-pricing method used to value the preferred shares themselves; see our detailed methodology on real options applied to startup valuation.

In practice, the gap depends on the exact terms of the financing round, the amount of the liquidation preference, whether it is participating or not, ratchet thresholds, and the weighting of the exit scenarios considered, which is why two companies that raised at the same per-share price can show meaningfully different ordinary share values. It is this allocation, documented in the valuation report, that protects the chosen strike price against a later audit.

BSA, BSPCE, AGA or stock options: which instrument for which objective

The choice of instrument depends first on the recipient and the objective pursued, well before any question of price.

Instrument	Beneficiaries	Company eligibility	Economic logic
BSA	Investors, third parties, external advisors	Any SA or SAS	Right to acquire shares at a fixed price, against a capital contribution
BSPCE	Employees and executives	Young company, art. 163 bis G of the Tax Code	Favorable tax regime to retain talent without diluting cash
Free shares (AGA)	Employees and executives	Any company, grant caps apply	Grant with no strike price, deferred acquisition
Stock options	Employees and executives	Any company, general meeting formalities	Historical regime, largely superseded by the BSPCE in startups

In practice, a recent management package often combines several of these instruments for the same beneficiary, part in BSPCE for the tax advantage, part in advisory BSA for a non-employee investor, each component requiring its own valuation and its own regime.

What drives the price: instrument, model, data, urgency

Five factors explain most of the price gap between two valuation engagements:

The type of instrument and the model it requires: a single BSA or BSPCE is valued using the closed-form Black-Scholes method, while an ABSA or an ORA with an early-redemption option requires a binomial model, or even a Monte Carlo simulation.
The number of instruments and beneficiaries: a plan granted in four tranches to fifty employees multiplies the sets of assumptions compared with a single grant.
Data availability: an up-to-date cap table, shareholders' agreement and business plan speed up the engagement, while scattered data lengthens the time needed to reconstruct it.
Urgency tied to a fundraising closing timeline or an imminent accounting close increases fees.
The level of defensibility sought: a report that must hold up to the tax authorities or URSSAF costs more than one for internal use only.

Flat fee or time-based: how a valuation engagement is billed in France

Most engagements are billed on a flat-fee basis once the scope is settled upfront: number of instruments, grant dates, volatility and risk-free rate assumptions to use. This billing mode suits a single BSA or a homogeneous BSPCE plan well. Time-based billing, by the hour, applies when the scope remains uncertain at the outset, a portfolio whose inventory is not finalized, or a structuring deal still under negotiation. Hectelion's hourly rate runs from EUR 150 to 800 depending on the technicality of the engagement, generally capped by a projected budget.

Hectelion's pricing: fees adjusted to the real complexity of the instrument

At Hectelion, fees for a BSA or BSPCE valuation engagement are adjusted to the real complexity of the file rather than to a generic rate per instrument type. A single BSA with no particular clause is billed at the low end of the range, while a management package combining BSPCE and BSA for about thirty beneficiaries is billed at the high end. The methodology applied stays aligned with the standards of the International Valuation Standards Council (IVSC), with economic independence from traditional financial intermediaries. Every quote details the number of instruments covered, the model chosen for each, and the production of a report documenting the assumptions, a condition for its later defensibility.

2026 trends: tighter URSSAF scrutiny, more management packages

Three trends shape the French market in 2026.

First, scrutiny by URSSAF and the tax authorities over the economic reality of the strike price set at BSPCE and AGA grants is tightening, with a risk of requalification as salary when the chosen price departs materially from the documented fair value.

Second, the spread of management packages combining several instruments, BSPCE for longtime employees, AGA for new hires, ABSA for LBO investors, within a single merger and acquisition or fundraising transaction, multiplies the number of reports to produce per file.

Third, artificial intelligence speeds up certain steps of the calculation, notably volatility calibration from listed comparables, without replacing expert judgment on choosing the model or on verifying the chosen instrument's tax eligibility.

Process and timeline: from scoping to the valuation report

Signing the engagement letter and scoping the perimeter of instruments to value.
Sending the documentation: shareholders' agreement, cap table, bylaws and grant minutes.
Checking the company's eligibility for the BSPCE regime where applicable.
Draft report presenting the model chosen, the calibrated assumptions and preliminary results.
Presentation of, and discussion on, the draft report with the client, and its auditor where applicable.
Incorporating requested corrections and additions.
Issuing the final valuation report.

This final report then serves to set the strike price, document the IFRS 2 accounting charge in the books, or secure the valuation used in a transaction.

Comparing providers: Big Four, boutique firms, online platforms

Three categories of providers operate in this market, each with legitimate use cases.

Big Four firms have dedicated teams and suit listed groups or large transactions well, at fees generally aligned with the high end of the range. Independent boutique firms, Hectelion among them, offer responsiveness suited to SMEs and mid-caps, with economic independence from traditional financial intermediaries.

Automated online platforms allow a quick, low-cost first calculation for a homogeneous BSPCE, useful for internal purposes, but reach their limits as soon as an instrument carries non-standard clauses or a multi-instrument management package, which call for expert judgment.

Why Choose Hectelion for Your BSA or BSPCE Valuation

Seven concrete points set Hectelion apart from other providers:

A practitioner's eye, not just a theorist's: before valuing BSPCE or BSA, Aristide Ruot founded companies and negotiated fundraising rounds; this lived experience shapes every assumption retained in the model, well beyond a mechanical application of Black-Scholes.
Systematic eligibility verification: before valuing a BSPCE plan, Hectelion checks the company's eligibility for the article 163 bis G regime, a step other providers skip.
A budget that follows real complexity: a single BSA does not cost the same as a management package combining several instruments, unlike the flat rate large firms often apply.
Technical mastery of option models: Black-Scholes, binomial or Monte Carlo depending on the clauses, led by Aristide Ruot, a finance Ph.D.
A single team from BSPCE to closing: financial instrument valuation, due diligence, fundraising and financial structuring are handled by the same points of contact.
No ties to the funds or intermediaries involved: Hectelion's compensation does not depend on any party to the underlying transaction.
A timeline set from the engagement letter: the report delivery deadline is announced at scoping and held to.

Point of caution: before signing an engagement letter, ask your valuer who pays them and how long they have worked with the parties to the transaction. A report produced by a provider already tied to the investors loses some of its evidentiary weight before an auditor or the tax authorities.

How to reduce the cost of your valuation without losing defensibility

Prepare the documentation upfront (shareholders' agreement, grant minutes) to avoid back-and-forth billed on a time basis.
Check the company's eligibility for the BSPCE regime before committing, rather than discovering an eligibility problem mid-engagement.
Stabilize the cap table structure before the mandate, rather than starting the engagement during a still-moving negotiation.
Group all instruments granted at the same valuation date into a single engagement.
Anticipate the strike price calculation from the scoping of a fundraising round, to avoid the markup tied to closing urgency.

None of these levers involves reducing the depth of the analysis or the documentation of assumptions, the only condition for the report's defensibility in a later audit.

Good leaver, bad leaver: what happens to an unvested instrument when a beneficiary departs

The shareholders' agreement accompanying a BSPCE plan or a management package almost always includes an early-departure clause, distinguishing the good leaver, who leaves for a legitimate reason, from the bad leaver, who resigns or is dismissed for cause.

A bad leaver generally forfeits the entire unvested portion of their plan, sometimes even part of the already-vested portion depending on the drafting, while a good leaver keeps all or part of their vested rights on a pro-rata basis. For the valuer, this clause introduces an additional option to model, the probability of a bad-leaver departure statistically reducing the plan's expected value for all beneficiaries.

The 5 mistakes that cost the most

Mistake 1: Issuing BSPCE without checking the company's eligibility

Granting BSPCE when the company no longer meets the criteria of article 163 bis G, for example after losing the 25% individual-ownership condition, exposes beneficiaries to a tax requalification of the benefit as salary.

Mistake 2: Using nominal value instead of fair value

Granting a BSA or BSPCE based solely on its nominal value or the last round's price, without a documented option model, exposes the company to requalification by the tax authorities or URSSAF, with a reassessment often exceeding the cost of a properly conducted initial valuation.

Mistake 3: Applying Black-Scholes to a path-dependent instrument

An ORA redeemable early or an ABSA with ratchet clauses cannot be correctly valued with a closed-form Black-Scholes formula: these instruments require a binomial model or a Monte Carlo simulation.

Mistake 4: Confusing the AGA regime with the BSPCE regime

Free shares and BSPCE follow distinct tax and social security regimes, with different grant caps and holding conditions; conflating them in a plan's documentation exposes it to challenge during an audit.

Mistake 5: Not documenting volatility and rate assumptions

A report that does not explicitly justify the chosen volatility, risk-free rate and dividend yield does not hold up to serious challenge in a tax or social security audit.

Case 1: BSPCE plan for a French startup, valued at EUR 4,500

Case built for illustrative purposes based on observed market practice.

Company G SAS, a B2B software publisher, Lyon. Three years old, eligible for the BSPCE regime. The company grants a BSPCE plan to 30 employees, in two tranches, with a one-year cliff and monthly vesting thereafter.

The quote comes to EUR 4,500, within the EUR 3,000 to 6,000 range for a single-class BSPCE plan, due to a simple cap table and documentation already gathered by the founder. The engagement runs three weeks and covers checking eligibility for the regime, valuing the underlying company, calibrating volatility from listed SaaS comparables, the Black-Scholes valuation of each of the two tranches, and the report for the statutory auditor.

Case 2: BSPCE and BSA management package for a French fundraising round, valued at EUR 8,500

Case built for illustrative purposes based on observed market practice.

Company I SAS, a B2B marketplace, Paris. The company raises a Series A round and grants, in the same transaction, an additional BSPCE tranche to 20 employees along with BSA to two strategic advisors who have supported it since inception.

The quote comes to EUR 8,500, within the EUR 6,000 to 12,000 range for a management package combining two distinct instruments, due to the two beneficiary populations and the two tax regimes to document separately. The engagement runs four weeks and applies a Black-Scholes valuation to each of the two instruments, with shared volatility assumptions but differentiated retention rates between employees and outside advisors.

A word from our founder

"A BSPCE never reduces to a formula applied mechanically. Before the model, there is eligibility: how many files discover an eligibility problem at the moment of an audit, when a check upfront takes only an hour."

"We see too many management packages granted on an approximate value, for lack of time before a closing. That approximation always costs more at the time of a review than it would have at the time of the grant."

"Our role is to document defensible assumptions, not to produce a number. That documentation, more than the number itself, is what protects the founder and the beneficiaries in the event of an audit."

FAQ: the 12 essential questions about the price of a BSA or BSPCE valuation

Introduction: what to remember before the questions

The price of a BSA or BSPCE valuation depends first on the type of instrument and the number of beneficiaries, before the size of the company itself. The following questions answer those most frequently asked by finance leaders, founders and investors in France.

Q1: How much does a BSA or BSPCE valuation cost?

Between EUR 3,000 and 6,000 for a single instrument, BSA, BSPCE, BSA-AIR or stock options, and between EUR 6,000 and 12,000 for a multi-instrument management package (Hectelion's 2026 practice).

Q2: How much does a BSA valuation cost?

Between EUR 3,000 and 6,000, valued using the Black-Scholes method. An optional 409A report, useful for documenting the strike price the American way, generally adds EUR 1,000.

Q3: How much does a BSPCE plan valuation cost?

Between EUR 3,000 and 6,000 for a single-class plan, and up to EUR 12,000 when the plan is part of a management package covering several instruments, depending on the number of beneficiaries and tranches.

Q4: How do I know if my company is eligible for the BSPCE regime?

The company must be incorporated for less than fifteen years, subject to French corporate income tax, unlisted or listed on a market under a regulatory capitalization threshold, and at least 25% held by individuals. This point should be checked with your advisor before any grant.

Q5: What is the difference between an AGA and a BSPCE?

An AGA grants shares for free, with no strike price, while a BSPCE gives the right to acquire shares at a price set in advance. Both follow distinct tax and social security regimes, with different grant caps.

Q6: How much does a BSA-AIR valuation cost?

Between EUR 3,000 and 6,000, the same range as a classic BSA, the conversion deferred to the next round simplifying, rather than complicating, the valuation at the date of the initial contribution.

Q7: Can the price of a BSA or BSPCE valuation be negotiated?

The most effective lever is grouping several instruments granted around the same dates into a single engagement rather than multiplying one-off missions: the marginal cost of an additional BSPCE within an already-scoped plan is well below the cost of a standalone quote. Reducing assumption documentation remains possible, but it weakens the report against a URSSAF or tax audit.

Q8: Who funds the engagement, the company or the BSA beneficiary?

The company granting the BSPCE or BSA pays for the engagement in nearly all cases. A frequent exception: for an advisory BSA granted to an outside investor or business angel, that investor sometimes asks to have the methodology reviewed by their own advisor, at their own cost, without changing who originally commissioned the valuation.

Q9: Are BSA or BSPCE valuation fees tax-deductible?

When the valuation accompanies a fundraising round or an M&A transaction, fees are most often attached to the cost of that transaction rather than deducted immediately as an expense; when it only documents an already-existing BSPCE plan, it is generally treated as an operating expense. This treatment should be confirmed with your accountant.

Q10: Does a BSPCE plan need to be revalued every year?

The strike price already set at grant does not need to be recalculated retroactively: it is each new tranche granted to a new beneficiary that requires its own valuation, at its issue date. The IFRS 2 charge already recognized continues to be spread over the remaining vesting period without being revised.

Q11: How long does it take to value a management package?

From two to four weeks for a single instrument to four to eight weeks for a multi-instrument management package, depending on data availability.

Q12: How do I choose a valuer for a BSA or BSPCE?

Check the provider's independence from your investors, their demonstrated ability to verify the instrument's tax eligibility, and the inclusion of complete assumption documentation in the report.

Conclusion: the price of a BSA or BSPCE valuation is read in the number of instruments, not the quote alone

The cost of a BSA or BSPCE valuation engagement is not a standalone figure, it reflects the number of instruments, the number of beneficiaries and the valuation model required. For a single instrument, BSA, BSPCE, BSA-AIR or stock options, the EUR 3,000 to 6,000 range covers most files, with management packages combining several instruments exceeding it.

Comparing quotes means comparing identical models, Black-Scholes against Black-Scholes, binomial against binomial, not just amounts, exactly as with any business valuation engagement.

Article summary

A BSA, BSPCE, BSA-AIR or stock option valuation in France costs between EUR 3,000 and 6,000 for a single instrument, and between EUR 6,000 and 12,000 for a management package combining several instruments.

The price varies with the type of instrument and the model it requires, the number of instruments and beneficiaries, data availability, the urgency of the timeline, and the level of defensibility sought. The two priced cases illustrate this: EUR 4,500 for a two-tranche BSPCE plan in Lyon, EUR 8,500 for a BSPCE and BSA management package in a Paris fundraising round. Above all, the company must check its eligibility for the BSPCE regime under article 163 bis G of the Tax Code, a step distinct from price but just as decisive.

Hectelion carries out BSA, BSPCE, BSA-AIR and stock option valuation engagements for French companies, in full independence from traditional financial intermediaries.
