If you’ve started exploring the process of selling your business, you may have come across the term “earnout” and wondered what it actually means in practice. It sounds straightforward, but earnouts are one of the more nuanced deal structures in a business sale, and they can work well or create real headaches depending on how they’re set up.
Here’s a plain-language breakdown of how earnouts work, why they come up, and what sellers need to understand before agreeing to one.
What Is an Earnout?
An earnout is a purchase agreement provision that lets a seller receive additional compensation after closing, contingent on the business meeting certain performance targets.
In a basic example: a buyer offers $3 million at closing, with the potential for an additional $500,000 if the business hits a defined revenue or earnings target in the 12 months following the sale. If the business hits that target, the seller receives the full $500,000. If it falls short, the seller receives a reduced amount or nothing at all, depending on how the earnout is structured.
The total potential payout, the upfront amount plus the maximum earnout, is sometimes called the “total consideration.” What the seller actually receives depends on what happens after they’ve handed over the keys.
Why Earnouts Come Up
Earnouts typically appear when there is a gap between what a buyer is willing to pay and what a seller believes the business is worth.
That gap usually comes from one of a few places.
Valuation disagreement. The seller believes the business is worth more than the buyer’s offer reflects. An earnout lets both parties move forward while deferring part of the valuation question to future performance.
Uncertain future performance. If the business recently launched a new product, expanded into a new market, or is in the middle of a growth phase, buyers may hesitate to pay a premium for results that haven’t materialized yet. An earnout lets the seller capture that upside if the growth plays out as expected.
Owner dependency concerns. If a significant portion of the business’s revenue depends on the seller’s personal relationships or involvement, buyers may structure an earnout to incentivize the seller to stay engaged during the transition and protect those relationships through the handoff.
Bridging financing gaps. In some transactions, earnouts let buyers offer more total consideration than they can fund entirely at closing, spreading part of the payment into the future when the business’s cash flow can support it.
How Earnouts Are Structured
The specific terms of an earnout matter enormously, and sellers need to pay close attention.
The metric. Earnouts tie to a performance metric, most commonly revenue, gross profit, EBITDA, or a combination. The choice of metric matters because different metrics can produce very different outcomes depending on how the new owner manages the business. Revenue is easier to measure but easier to manipulate through discounting or deferral. EBITDA is a more meaningful profitability measure but is more susceptible to accounting decisions the buyer controls.
The target. What specific number does the business need to hit? How is the baseline calculated? Is the target a single threshold or a tiered structure where the seller receives partial payment for hitting intermediate milestones?
The timeframe. Most earnouts run one to three years. Longer earnouts introduce more uncertainty and more opportunities for disagreement. Shorter earnouts may not capture the full performance trajectory the seller expects.
Measurement and reporting. How will performance be calculated and who controls the accounting? This is one of the most important and most frequently overlooked aspects of an earnout. If the buyer controls the books and can make decisions that reduce reported EBITDA, including new overhead, management fees, or accounting adjustments, the seller is exposed.
Seller protections. Strong earnout agreements include provisions that protect the seller’s ability to hit the targets: requirements that the buyer fund the business adequately, operate it consistently, avoid redirecting revenue or customers, and report results transparently. Without these protections, earnouts can be structured in ways that make them very difficult to collect.
The Real Risks of Earnouts for Sellers
Earnouts are often presented as a win-win: the buyer pays less upfront, the seller has the opportunity to earn more. In practice, the risk is not evenly distributed.
Once the deal closes, the seller no longer controls the business. The buyer makes operational, hiring, pricing, and accounting decisions. All of those decisions affect whether the earnout targets are met.
A motivated buyer who runs the business well and acts in good faith gives a seller a real shot at collecting the full earnout. A buyer who prioritizes its own interests, takes on excessive overhead, redirects profitable customers to other entities, or manages the business differently than the seller expected can make earnout targets very difficult or impossible to hit, often without technically violating the agreement.
This doesn’t mean earnouts are inherently bad or that all buyers act in bad faith. It does mean that the quality of the earnout language in the purchase agreement and the buyer’s trustworthiness are both critical factors. You need an attorney who understands earnout structures and will fight for protective provisions, and you need to take seriously what you know about the buyer before agreeing to leave a significant portion of your sale price contingent on their decisions.
When an Earnout Makes Sense for Sellers
In some situations, accepting an earnout is a reasonable decision.
If the alternative is walking away from the deal entirely, and you genuinely believe in the business’s trajectory and the buyer’s capability, an earnout may be worth the risk. If the upfront component is strong enough that you’re financially whole regardless of whether the earnout pays out, the additional upside is worth pursuing. If the earnout is tied to a metric you can directly influence during a transition period, such as revenue from relationships you’re actively managing through the handoff, the risk is more manageable.
Sellers should avoid treating an earnout as guaranteed compensation. It is contingent compensation, and any financial planning that depends on it should account for the possibility that it pays out partially or not at all.
Negotiating an Earnout
If an earnout is going to be part of your transaction, your leverage is highest before you sign the LOI. Once you’ve agreed in principle to an earnout structure, negotiating the protective provisions becomes harder.
Push for clear, objective metrics the buyer can’t easily manipulate. Push for tiered targets so that partial performance still results in partial payment. Push for explicit protections requiring the buyer to operate the business consistently and fund it adequately. Push for transparent, regular reporting with audit rights. And make sure the default provisions are clearly defined, including what happens if the buyer sells the business again before the earnout period ends.
Your attorney and your broker should both actively review and negotiate these terms. Don’t accept generic language or assume the buyer’s proposed structure is balanced.
The Bottom Line
Earnouts are a legitimate and sometimes useful tool in business sale transactions. They can bridge valuation gaps, let deals move forward amid uncertainty about future performance, and give sellers the chance to capture upside they believe in.
They also come with real risk, and that risk falls disproportionately on the seller once the deal closes. To approach one responsibly, you need to understand the structure, negotiate protective provisions, and go in with a clear-eyed view of what the earnout is actually worth.
