Earn-outs explained: when part of the price comes later

Short answer. An earn-out is the part of a sale price that's paid later, only if the business hits agreed targets after closing. Buyers use it to bridge a price gap and share the risk of future results. For the seller it's uncertain money: the metric, the period, the accounting rules and how much control you keep decide whether it's ever paid.

Key takeaways

• You often don't get everything at once: part at signing, part tied to the following months' results.
• An earn-out shifts risk from the buyer to you, after you've handed over control.
• The definitions matter more than the headline: metric, period, accounting rules, reporting.
• Value an earn-out at a discount to cash at closing when you compare offers.
• Make sure the closing payment alone is a price you'd accept.

What is an earn-out?

In a sale with an earn-out, the price is split in two:

1. A fixed part, paid at closing (and sometimes in fixed instalments).
2. A conditional part, paid later if the business reaches agreed targets over a set period after closing.

The targets are usually revenue, gross profit or EBITDA, measured over months or years. Hit them and you receive the conditional part. Miss them and you receive less, or nothing.

Why do buyers propose earn-outs?

Because there's a gap between what you think the business is worth and what they're willing to pay with certainty. Common reasons:

• Recent growth. Your last six months are much better than the previous twelve. The buyer isn't sure it will last.
• Concentration. One product or one channel drives most of the revenue.
• Owner dependence. The business relies on you, and the buyer wants you motivated during the transition.
• Financing. The buyer can't pay the full price at closing.

An earn-out lets the buyer say yes to your price, as long as the business proves it.

How often are earn-outs used, and how often do they pay?

For broad context: SRS Acquiom, which administers payments on private M&A deals, reports that 24% of private-target deals outside life sciences in 2025 included an earn-out (SRS Acquiom, Earnout and Milestone Trends). It also notes that across all deals with an earn-out in its data, closer to one out of five dollars gets paid.

Read those numbers with their perimeter. They describe private M&A deals SRS Acquiom worked on, which are generally much larger than eCommerce brand sales, and the payout figure includes sectors with very uncertain milestones. They're not a forecast for your store. They are a reminder that money tied to future results is not money in the bank.

What makes an earn-out fair, or not?

The metric

• Revenue is the easiest to measure and the hardest for the buyer to influence through cost decisions. Sellers often prefer it.
• Gross profit reflects product margin but depends on purchasing and pricing decisions the buyer controls.
• EBITDA or net profit is what the buyer is paying for, but it's exposed to every cost decision after closing: new hires, agency fees, group overheads.

Whatever the metric, define it precisely: which revenue (net of refunds and chargebacks?), which costs, which accounting rules.

The period

Shorter periods mean less time for things outside your control to happen. Longer periods mean more risk. Measuring in several smaller steps, each with its own payment, is often fairer than one big all-or-nothing target at the end.

All-or-nothing versus sliding scale

An all-or-nothing target means missing it by a small margin costs you the whole conditional part. A sliding scale pays proportionally. Ask for the second.

Control after closing

After closing, the buyer runs the business. They can change the ad budget, raise prices, merge your store with others, move the team. Each of these can affect whether you hit the target.

Protections worth negotiating:

• an obligation to run the business in the ordinary course, consistent with how it was run;
• no moving revenue or costs between your brand and the buyer's other businesses;
• your access to the monthly numbers used for the calculation;
• acceleration, meaning the earn-out is paid in full if the buyer sells the business or breaks the agreement;
• a clear process and an independent expert for disputes.

Your role

If you stay on, define your role, your authority and what happens if the buyer removes you. An earn-out that depends on your work, with no control over the resources, is a trap.

How do I compare an offer with an earn-out?

Put each offer in the same table: cash at closing, fixed deferred payments, conditional payments. Then discount the conditional part for risk and time. There's no formula, but ask yourself: if the earn-out paid nothing, would the closing payment still be acceptable?

If the answer is no, you're betting the sale on targets measured while someone else runs the business. Sometimes that's a good bet. Make it knowingly.

We show a side-by-side example in lowball offers and re-trades, and the full list of terms to check in the letter of intent.

The figures are illustrative, to show how the terms fit together. They're not a benchmark.

Written like this, both sides know exactly what has to happen and how it's measured. Compare it with "up to €100,000 based on performance", which says nothing about any of it.

Questions to ask before you accept an earn-out

• Why does the buyer want it? Which specific risk does it cover?
• Could that risk be covered by a smaller amount, or a shorter period?
• Who decides the ad budget, prices and stock levels during the period?
• Will the brand's numbers be kept separate from the buyer's other businesses?
• What happens if they fire me, sell the brand or merge it with another?
• How and when do I see the numbers used for the calculation?
• Who settles a disagreement, and how quickly?

If the buyer can't answer these clearly, the earn-out isn't ready to sign.

Are there alternatives?

• Seller financing. A fixed amount paid over time with interest, not tied to targets. It has its own risks, mainly the buyer's ability to pay. See seller financing.
• A lower price, all at closing. Less upside, no uncertainty.
• A shorter, smaller earn-out covering only the part of the price the buyer really doubts.

What about taxes?

How an earn-out is taxed depends on your country, the structure of the sale and how the agreement is written. Ask your advisor before you sign, not after. We list the questions worth asking in taxes when selling an online business.

How WiseExit helps

Part of the price paid later can be a fair way to close a gap. It can also be where a good headline turns into a weak deal. We make sure payment terms are as clear as the price, and compare offers on what you receive, when and on what conditions.
