What Is an Earnout in a Business Sale?

What It Is

An earnout is a portion of the business sale price that is paid after closing, contingent on the business hitting specific performance targets — usually revenue, EBITDA, or customer retention thresholds — over a defined measurement period of 12 to 36 months. Earnouts typically represent 10% to 30% of total deal consideration in sub-$10M lower middle market sales, with 15–20% being the most common range.

The earnout exists to bridge a valuation gap. When the seller believes the business will perform meaningfully better than the trailing twelve months and the buyer is not willing to pay for performance they haven't seen, the earnout lets both sides participate in the upside. The seller gets paid more if they're right; the buyer doesn't overpay if they're wrong. Earnouts appear in roughly 60–70% of sub-$10M business sales in 2026 — they're not the exception, they're the norm.

Why It Matters

Earnouts matter for three reasons that most sellers don't appreciate until they're three years past closing and short a check.

• Earnout dollars are not guaranteed dollars. A $1M earnout structured around aggressive forward EBITDA targets has a meaningful probability of paying $0. Industry research suggests well-structured earnouts pay out 70–85% of the maximum amount; poorly structured ones often pay below 40%. The "headline" purchase price you accept means very different things depending on earnout structure.
• The buyer controls the business post-close. If your earnout is based on EBITDA, the buyer can (legally and routinely) shift costs into the earnout period, allocate corporate overhead, integrate operations into a parent company, or change accounting policies — all of which can compress the EBITDA you'd otherwise hit. Without negotiated protections, earnouts often fail not because the business underperformed but because the metric was manipulated.
• Earnouts often replace negotiated price, not add to it. A buyer offering $4M cash + $1M earnout for what should be a $5M deal isn't paying you $5M — they're paying $4M with a chance at more. Compare offers on the risk-adjusted basis, not the headline.

YourExitValue tracks earnout terms across recent deals in how PE firms value businesses and what buyers look for so you can compare offers on apples-to-apples terms — not on headline numbers that disguise back-loaded risk.

How to Use It

If a buyer offers you an earnout, three actions matter most.

• Pick a metric you control. Revenue-based earnouts pay out more often than EBITDA-based earnouts because revenue is harder for the buyer to manipulate post-close. If the metric must be EBITDA, negotiate add-back protections: specifically exclude integration costs, shared services allocations, parent company management fees, severance, and transaction-related expenses from the earnout EBITDA calculation. Without these exclusions, the buyer will load costs into the earnout period and your payout will compress.
• Negotiate operational covenants. The buyer should be contractually limited in how they integrate the business during the earnout period. Common covenants: no closing of locations, no terminating key employees without cause, no changing pricing without seller consent, no shifting customers to a parent company. Without these, the buyer can change the business in ways that mechanically reduce the earnout.
• Cap your tail risk on the upside. If the business meaningfully outperforms, you should get paid for it. Negotiate an "accelerator" clause: if the business hits 120% of the target metric, the earnout pays 110% of the maximum. This aligns the buyer with you on growth, rather than incentivizing them to coast at the threshold.

The single biggest mistake sellers make on earnouts is treating them as fixed dollar amounts in the headline price. They're not — they're risk-adjusted contingent payments that depend heavily on how you negotiate the structure. Use the YourExitValue exit planning framework to evaluate every offer with explicit earnout probability assumptions — not by adding the earnout maximum to the cash portion as if both will land in your bank account.
