Why seller net proceeds matter more than the headline M&A price
A press release, indication of interest, or letter of intent may display one large transaction value, but that figure is rarely the amount retained by the seller group.
If the headline is enterprise value, cash and agreed non-operating assets may be added while debt and debt-like items are deducted, followed by the working-capital or other purchase-price adjustment.
Only after applying the ownership actually sold does the model reach fixed consideration attributable to the seller group being analyzed.
The funds-flow bridge continues beyond that point.
Fixed consideration held in escrow, a contingent earnout, advisory retainer and success fee, legal and accounting costs, indirect tax, and a separately reviewed transaction-tax reserve can materially change the amount and timing of value retained.
This calculator keeps those pieces in one currency and one seller boundary, then shows expected nominal and present-value net proceeds without claiming that any deferred amount will be collected.
Four outputs to use in a deal discussion
- Seller fixed consideration: adjusted equity value allocated to the seller group.
- Contract success fee: fee base and rate after the contractual minimum, cap, and retainer-credit sequence.
- Expected nominal net proceeds: probability-weighted proceeds less total seller economic costs.
- Expected present-value net proceeds: expected deferred consideration discounted to the closing date.
Separate enterprise value, equity value, and seller consideration
1. Enterprise value
A headline for the operating business is often discussed on a cash-free, debt-free basis.
The agreement definition controls, and this calculator does not value the business or infer included liabilities.
2. Equity value
Add agreed cash and non-operating assets, deduct debt and debt-like claims, and apply the working-capital or price adjustment.
If the headline input is already equity value, cash and debt are not applied again.
3. Seller fixed consideration
Multiply planning equity value by the ownership sold by the seller group in scope.
The earnout remains additional contingent consideration rather than part of this fixed amount.
Enterprise-value input: equity value = headline EV + cash − debt + working-capital adjustment.
Equity-value input: equity value = headline equity value + working-capital adjustment.
Seller fixed consideration: planning equity value × ownership sold.
Evidence to align before entering a deal
Reliable proceeds planning begins by reconciling definitions, not by adding more decimal places.
A headline in the LOI, the adjustment mechanics in the SPA, the closing funds-flow, and the advisory agreement can each use a different boundary unless they are explicitly aligned.
- Headline basis: identify enterprise value versus equity value and whether the term is cash-free and debt-free.
- Net-debt schedule: list cash, borrowings, leases, accrued interest, shareholder loans, preferred claims, and other debt-like items included by contract.
- Working-capital schedule: align the target, closing balance, leakage, and one-time price adjustments under one sign convention.
- Seller allocation: separate the ownership sold, cost sharing with other holders, rollover equity, and noncash consideration.
- Payment schedule: identify cash at closing, holdback or escrow, earnout amount, conditions, and latest payment date.
- Advisory agreement: document the fee base, minimum, cap, retainer credit, earnout treatment, tax, and reimbursable cost clauses.
- Tax memo: estimate taxes, filing costs, payment dates, and uncertainty reserves by transaction form and seller.
Contract success-fee calculation order
Multiplying a headline value by one percentage is not enough when the engagement includes a minimum, cap, retainer, or a different definition of transaction consideration.
The calculator follows a fixed sequence so that each clause remains visible.
Step 1 — Select the fee base
Choose headline enterprise value, adjusted total equity value, seller fixed consideration, or seller potential consideration including the maximum earnout, according to the actual agreement.
Step 2 — Calculate the percentage fee
Multiply the selected contract base by the entered success-fee rate. The rate is a user-entered contract term, not a market benchmark.
Step 3 — Apply the minimum and cap
Raise the percentage fee to the minimum when necessary, then limit it to a positive cap. A zero cap input means there is no cap.
Step 4 — Apply retainer credit
If the retainer is creditable, subtract it from the contract success fee and floor the closing success balance at zero. No retainer refund is assumed.
Step 5 — Add other fee and indirect tax
Add the retainer, success balance, and other advisory fee on a consistent tax basis, then apply the user-entered indirect-tax rate.
Core success-fee formulas
Percentage success fee = contract fee base × success-fee rate.
Contract success fee = min(max(percentage fee, minimum), positive cap).
Credited success balance = max(0, contract success fee − retainer).
Advisory fee before indirect tax = retainer + success balance + other advisory fee.
Invoice cash and economic indirect-tax cost can differ
For a Korean example, the National Law Information OPEN API confirmed current VAT Act ID 001571, MST 276117, effective January 2, 2026.
Article 30 states a 10% VAT rate, which is why the Korean calculator starts with 10% as an editable example.
That statutory rate alone does not determine whether a particular advisory service is taxable or whether a seller can recover the input tax.
Advisory cash outlay
Add the full invoice indirect tax to the advisory fee before tax.
This is the cash needed when the invoice is paid, before any later recovery.
Advisory economic cost
Add only the nonrecoverable portion of indirect tax to the fee before tax.
The model excludes from economic cost only the recovery percentage entered after tax review.
Korean VAT Act Article 38 provides the basic boundary for input tax on goods or services received for a business, while Article 39 identifies exclusions involving invoice requirements, direct business connection, exempt activities, and other cases.
The calculator cannot identify the recipient, business use, exempt or taxable mix, allocation method, or invoice validity, so the VAT recovery percentage remains a user input.
The English example defaults to 0% indirect tax because it is global; enter the applicable jurisdiction-specific rate and recovery only after review.
Model holdback and earnout probability separately from timing
A holdback is part of fixed consideration but remains unavailable after closing, often subject to indemnity or final price adjustments.
An earnout is additional contingent consideration linked to revenue, EBITDA, regulatory, customer-retention, or another performance condition.
Treating every maximum as certain can overstate value, while assigning zero to every contingent payment can hide negotiating value.
Expected proceeds and present-value formulas
- Expected holdback = fixed holdback × receipt probability.
- Expected earnout = maximum earnout × achievement probability.
- Present value of a future expected payment = expected payment ÷ `(1 + annual discount rate)^(payment months ÷ 12)`.
- Expected nominal gross proceeds = fixed proceeds at closing + expected holdback + expected earnout.
- Expected PV gross proceeds = fixed proceeds at closing + expected holdback PV + expected earnout PV.
Probability is not a legal collectability opinion
Support the input with operating history, control after closing, KPI definitions, accounting-policy rights, setoff and indemnity clauses, information access, and dispute procedures.
If an earnout has several independent or sequential milestones, estimate each expected payment separately and combine them conservatively before using this simplified field.
Worked USD seller-proceeds example
The fictional English example starts with USD 10,000,000 of enterprise value, adds USD 1,000,000 of cash, deducts USD 2,000,000 of debt, and applies a negative USD 200,000 working-capital adjustment.
The seller group disposes of 80%, USD 800,000 is held for 12 months with a 90% receipt probability, and a maximum USD 1,000,000 earnout is expected after 24 months with a 60% probability.
The annual discount rate is 8%.
Worked USD M&A advisory fee and seller net-proceeds example| Line | Formula or interpretation | Amount |
|---|
| Adjusted equity value | 10.0m + 1.0m − 2.0m − 0.2m | USD 8,800,000 |
| Seller fixed consideration | USD 8.8m × 80% | USD 7,040,000 |
| Fixed proceeds at closing | USD 7.04m − USD 0.8m holdback | USD 6,240,000 |
| Expected nominal gross proceeds | USD 6.24m + 0.8m×90% + 1.0m×60% | USD 7,560,000 |
| Expected PV gross proceeds | Holdback at month 12 and earnout at month 24 | USD 7,421,070 |
| Contract success fee | USD 7.04m × 2%, within minimum and cap | USD 140,800 |
| Advisory economic cost | Retainer-credit balance plus other fee, 0% example tax | USD 150,800 |
| Total seller economic costs | Advisory + legal/accounting + other cost + tax reserve | USD 1,250,800 |
| Expected nominal net proceeds | USD 7.56m − total economic costs | USD 6,309,200 |
| Expected PV net proceeds | USD 7,421,070 − total economic costs | USD 6,170,270 |
The USD 1,000,000 tax reserve and 2% success-fee rate are fictional mechanics, not market averages, recommended terms, or a tax estimate.
Replace every amount with a consistent seller-specific deal record.
How to interpret the two sensitivity tables
Success-fee rate ±0.5 percentage points
Only the contract rate changes; the calculator then reapplies the minimum, cap, retainer credit, and indirect tax.
A binding minimum can prevent savings from a lower percentage, while a binding cap can prevent added cost from a higher percentage.
Zero, entered, and full recovery
Compare no holdback or earnout recovery, the entered expectation, and full recovery while holding seller costs constant.
If advisory compensation is based on potential consideration, a lower collection probability does not automatically reduce the contractual fee.
Pre-signing contract checklist
Advisory engagement
- Definition of success and payment trigger.
- Enterprise value, equity value, realized proceeds, or another compensation base.
- Treatment of cash, debt, earnout, rollover equity, assumed liabilities, and noncash consideration.
- Minimum, cap, milestone fees, retainer credit, and refund terms.
- Tail period, introduced buyers, termination, and excluded counterparties.
- Indirect tax, expenses, co-advisers, finders, and duplicate compensation.
Purchase agreement and funds flow
- Net-debt and working-capital dates, methods, and dispute resolution.
- Closing payment, escrow, holdback, setoff, and release conditions.
- Earnout KPI, accounting policy, buyer operating discretion, and information rights.
- Representations, indemnity cap, basket, deductible, and survival period.
- Proceeds, cost, and tax allocation among sellers.
- Currency conversion, transfer charges, withholding, and tax-payment evidence.
Practical uses
Normalize advisory proposals
Do not compare percentage headlines alone.
Normalize the compensation base, minimum, cap, retainer credit, earnout treatment, expenses, and indirect tax, then compare effective fee rate and advisory burden against the same expected proceeds.
Compare competing LOIs
A higher headline can still deliver lower present-value net proceeds after debt deductions, working-capital mechanics, escrow, earnout, and seller costs.
Compare price, payment certainty, and timing under one seller proceeds boundary.
Prepare the closing funds flow
Subtract total advisory invoice cash and all other entered costs from fixed proceeds at closing.
If the result is negative, revisit the actual payment dates for retainer, tax, cost sharing, and financing rather than treating the simplified closing-cost assumption as a literal bank balance.
Scope limits and cautions
- The calculator does not compute capital-gains, corporate-income, securities-transaction, sales, value-added, withholding, or transfer taxes for share, asset, domestic, or cross-border deals.
- A zero tax reserve is not an exemption conclusion; enter a reserve based on transaction-form and seller-specific tax advice.
- Rollover equity, buyer shares, assumed financing, noncash consideration, and foreign currency must be valued and included consistently by the user.
- Holdback and earnout probabilities do not guarantee enforceability, collection, or dispute outcomes; review post-closing control and KPI-manipulation risk separately.
- The discount rate is a timing assumption, not a business-valuation discount rate, statutory rate, required return, or investment recommendation.
- All seller costs are treated as closing-date economic costs for comparison; actual invoice, tax, and refund timing requires a separate cash-flow schedule.
- The result is not an IVS-compliant valuation, IFRS 3 accounting conclusion, fairness opinion, contract interpretation, tax filing, or guarantee that a transaction will close.
Frequently asked questions
Q. Does this calculator provide a market success-fee rate?
No. Sector, deal size, exclusivity, mandate scope, difficulty, competition, and jurisdiction can change commercial terms. Enter actual proposals and contract terms.
Q. Should I enter enterprise value or equity value?
Follow the LOI or SPA definition. Choose enterprise value for a cash-free, debt-free headline that still needs cash and debt adjustments; choose equity value for an aggregate share price that already reflects them.
Q. What is the difference between holdback and earnout?
A holdback is fixed consideration paid later and potentially reduced by claims or adjustments. An earnout is additional consideration triggered by future performance. Do not enter the same amount in both fields.
Q. Does retainer credit create a refund?
No. When the credited retainer exceeds the contract success fee, the success balance is floored at zero. Any refund, carryforward, or nonrefund clause must be reviewed in the agreement.
Q. What should I use for indirect-tax recovery?
Use a percentage supported by tax review of the recipient, invoice, business connection, exempt activity, and allocation rules. The calculator does not apply Korean Article 38 or Article 39 to your facts.
Q. Why are transaction taxes not calculated?
Share versus asset form, individual versus entity seller, residence, ownership history, consideration type, and jurisdiction can change the tax base and rate. This tool connects a separate tax workstream to the proceeds bridge.
Q. Is expected PV net proceeds the amount I will receive?
No. It is a closing-date economic comparison using your probability and discount-rate assumptions. Nominal payments, release dates, setoff, and disputes remain governed by the transaction documents and performance.
Q. Can I compare several buyers?
Yes, but run each LOI as a separate scenario with its own value definition, deductions, payment schedule, earnout, costs, and tax reserve. Do not compare only the final headline value.
