Earn-Out in a Business Sale: What Is It, and How Does It Work?

An earn-out is an agreement structure where part of the purchase price isn't paid at takeover, but later — conditional on the business reaching certain targets after the sale, for example a given revenue or earnings level. It's typically used when buyer and seller don't fully agree on the price, or when the buyer wants to reduce the risk of the deal.

How does an earn-out work in practice?

Instead of paying the entire purchase price on the takeover day, the parties agree on a base price paid immediately, and an additional payment triggered if the business, within an agreed period after the sale, reaches specific performance targets — often revenue, profit or customer retention. The period is typically 1–3 years.

Why is it used?

• Bridges expectations: If the seller believes the business is worth more than the buyer is willing to pay immediately, an earn-out can give the seller the chance to get the full price — if the business performs as expected.
• Reduces the buyer's risk: The buyer doesn't pay for future earnings that never materialize.
• Retains the seller's engagement: If the seller stays with the business for a period after the sale, an earn-out gives a direct incentive to keep contributing to the business's success.

What are the drawbacks?

• Uncertainty about the final price: The seller doesn't know for certain what the total sale amount will actually be.
• Risk of disagreement: What counts as an "achieved target" can give rise to dispute — particularly if the buyer has influence over the business's operations during the earn-out period.
• Lock-in period: The seller is often still involved in the business during the earn-out period, which can feel like an extension of the sale process.
• Complexity: Earn-out agreements require precise formulation of how the targets are measured, and what happens with unforeseen events along the way.

What should an earn-out agreement always contain in a business sale?

• Clearly defined, measurable criteria for when the additional payment is triggered.
• Who has control over the business's operations during the earn-out period, and which decisions the seller can have influence over.
• What happens if the business partially reaches the targets — a graduated payout rather than all-or-nothing.
• How any disagreement about the calculation should be resolved.

Considering an earn-out structure in your deal? It's one of the points that should be clarified early in a letter of intent. Book a no-obligation call if you'd like help negotiating and drafting the agreement correctly.
