What to Negotiate Most earnouts last between one and three years. A 2025 summary of deal data put the median performance period outside life sciences at 24 months. A shorter period lowers your risk, but the metric, the buyer's control and the payout terms matter just as much.

Most earnouts last between one and three years. The median performance period outside life sciences is 24 months. Longer periods exist, but they are the exception for business services companies. Cantrell Law, a business law firm, says “most earnouts last between one and three years.” The Harvard Law School Forum on Corporate Governance published a July 2025 post by the law firm A&O Shearman. It reports that “the median length for the earn-out performance period for transactions outside the life sciences sector is 24 months.” Life sciences deals run 3 to 5 years or more because approvals take time. Those deals are not a fair guide for a services company. ## What is an earnout, and why do buyers ask for one? An earnout is part of the purchase price paid after closing, and only if the business meets agreed targets. Buyers use it when they and the seller disagree on what the business will earn. Cantrell Law says it lets a seller “capture upside if the company hits its numbers” and protects the buyer from overpaying. Altair Advisers adds that private equity deals “usually include a third component” beyond cash and rollover equity, which is earnout payments. Our [earnouts guide](https://capstreet.multisites.ai/guides/earnouts) and the glossary entry for [earnout](https://capstreet.multisites.ai/glossary/earnout) cover the basics. ## How big is a typical earnout? Size varies, so look at the share of the price at risk. The Harvard Forum post reports that the median earnout outside life sciences was 31% of closing payments in 2024. That figure includes escrowed amounts. It came in at 34% in 2023 and 30% in 2022. A larger earnout means more of your price depends on what the buyer does after closing. Compare offers by counting the earnout as uncertain money, not as cash. A lower price with more cash at closing can be worth more than a higher price that depends on targets. ## What should you negotiate besides the length? Length is one term of several. The metric, the buyer’s control over the business and the payout rules matter as much as the number of months, so negotiate them together as one package. Term What to push for Why it matters Period The shortest period that fits your sales cycle Less time for conditions to change Metric A measure the buyer cannot easily shape, such as revenue or gross profit Net income can be moved by cost choices Definitions Exact accounting rules and add-backs Vague terms cause disputes Control Limits on how the buyer runs the business Protects the numbers you are paid on Dispute process An independent accountant, with clear timing Avoids court Sale of the company Acceleration, assumption or a buyout Sets what happens if the buyer resells Cantrell Law says to accept an earnout only when the metric is one the buyer cannot easily manipulate and the period is short. Name the exact metric, not just “EBITDA,” and spell out what counts. ## Why do earnouts cause so many disputes? Earnouts cause disputes because the buyer controls the business while you are paid on its results. Targets can feel just out of reach, and each side reads the numbers differently. Altair Advisers says in its experience “the metrics and timeframes often seem to be just out of reach and are the source of many post-transaction conflicts.” Cantrell Law adds that a contested claim “can cost both sides hundreds of thousands of dollars in legal and accounting fees, and can take years to resolve.” The best protection is precise drafting before closing. Altair offers a blunt test: if the price does not make sense without the earnout, the deal does not make sense. ## What happens if the buyer sells or merges the company? The contract decides what happens to your earnout if the buyer resells or merges the company. If the agreement is silent, expect a fight, so ask your lawyer to address a resale in the agreement. Cantrell Law says most agreements pick one of three paths: acceleration, assumption or a buyout. In acceleration, the full earnout becomes due at once. In assumption, the new buyer takes over the obligation. In a buyout, the original buyer pays an agreed lump sum. Sellers usually prefer acceleration. Cantrell Law also flags integration as a risk. If the buyer folds your company into its own on day one, separating the results becomes hard.

Cash, rolled equity and an earnout make up the typical offer. Compare all three. The glossary defines [earnout](https://capstreet.multisites.ai/glossary/earnout), [rollover equity](https://capstreet.multisites.ai/glossary/rollover-equity) and [escrow](https://capstreet.multisites.ai/glossary/escrow). Our post on [rollover equity](https://capstreet.multisites.ai/insights/what-is-rollover-equity) covers the second piece. The [letter of intent guide](https://capstreet.multisites.ai/guides/letter-of-intent) shows where these terms first appear.

Capstreet has not published a standard earnout term, and this post does not state one. Ask any buyer for its earnout terms in writing before you sign. Tax and legal treatment varies, so ask your own adviser to review the language. ## Next step If you are weighing a sale and want to talk through structure, start with [our deal criteria](https://capstreet.multisites.ai/deal-criteria).

Most earnouts last between one and three years, according to Cantrell Law. The median performance period for deals outside life sciences is 24 months, as reported in a 2025 Harvard Law School Forum post by A&O Shearman. Life sciences earnouts run longer because milestones take time. ### What is an earnout in a business sale? An earnout is part of the purchase price that the buyer pays after closing, only if the business hits agreed targets during a set period. It can close a gap between what you want and what the buyer will pay up front. Treat it as uncertain money, not cash in hand. ### What metric is safest for a seller? Cantrell Law says to accept an earnout only when the metric is one the buyer cannot easily manipulate, such as revenue or gross profit rather than net income. Define the metric to the letter, and spell out the accounting rules in the agreement. ### What happens to my earnout if the buyer sells the company? It depends on the contract. Cantrell Law says most agreements use acceleration, assumption or a buyout. Sellers usually prefer acceleration, where the full earnout is due at once. If the agreement is silent, disputes are almost certain. Ask your lawyer to address it. ## Terms on this page - [Letter of Intent](https://capstreet.multisites.ai/glossary/letter-of-intent) - [Rollover Equity](https://capstreet.multisites.ai/glossary/rollover-equity) - [Private Equity](https://capstreet.multisites.ai/glossary/private-equity) - [Add-Backs](https://capstreet.multisites.ai/glossary/add-backs) - [Earnout](https://capstreet.multisites.ai/glossary/earnout) - [EBITDA](https://capstreet.multisites.ai/glossary/ebitda) - [Escrow](https://capstreet.multisites.ai/glossary/escrow) ## Sources 1.
