How Earnouts Work in Business Sale Transactions

What is earnout in a business sale? If you’re selling your company for the first time, this question might come up, especially when forming post-sale goals. Worries about missing your target price are common.

Once you discover the answer to the questions “what is an earn out,” or “what is an earn out when selling a business,” you’ll see it’s a performance-based payment structure that bridges valuation gaps between buyers and sellers, tying 10-30% of the price to hitting targets like revenue or EBITDA over 1-3 years.

What is an Earnout?

Earnout Definition

An earnout is a way for a buyer and seller to “meet in the middle” on a business sale price. Instead of paying everything upfront, the buyer agrees to pay part of the price later, only if the business hits certain performance goals after the same.

What is an earnout in a Business Sale?

Earnouts are typically profit-based (like EBITDA) or total sales, but they can be based on other factors depending on the deal. The arrangement is common when the buyer wants reassurance that the business will keep performing well, and the seller believes it will. In short, they link part of your payout to how the business actually performs after you hand over the reins.

Common Terms and Concepts

Earnout period. What is an earnout period? It is the defined period post-closing wherein the business performance is measured to determine whether the seller has entitlement over contingent payments stipulated by the earnout terms.

Contingent payment obligation. The buyer’s obligation to pay additional amounts to the seller if the agreed-upon performance conditions on the purchase agreement are achieved within the earnout period.

Earnout payments. The actual post-closing payments given to the seller when the business meets the agreed performance targets or milestones within the pre-determined earnout period.

Earnout structure. The specific design of how the earnout works.

Key Takeaways

• Earnouts are structured around components, including what to measure, how long to measure it, how to convert results into payments, and what guardrails apply so buyers and sellers can hang contingent value on a clear, agreed‑upon framework.
• An earnout payment happens when chosen metrics hit the trigger levels in the deal.
• Earnouts add a second layer of risk on top of normal deal uncertainty, so you manage that by taking measurement out of either party’s hands, bringing in a neutral accountant, and tightening the rules around calculations and access to records.
• Earnouts exist to keep deals alive when buyers and sellers can’t agree on value, tying part of the price to future performance so neither side has to fully cave on today’s number.
• A solid purchase agreement just makes the earnout mechanics objectively clear, so both sides know exactly how future payments will work.

The Structure of Earnouts

Earnout Structures

When you learn the “earnout sale of business,” you’ll discover that the first step is to agree on what really drives the business’s value. These “value drivers” are the performance measures that matter most—things like revenue growth, profit margins, or customer retention. Both the buyer and seller should feel confident that these targets reflect what makes the company successful and that they’ll keep the management team motivated to hit those goals after the sale. 

Every business sale deal structure with earnout typically falls into a few recognizable categories:

• When a fixed percentage is the basis, the seller receives a set percentage of a chosen performance metric (e.g., EBITDA or revenue) based on results achieved during the designated earnout period.
• Tiered earnouts apply escalating payout levels as the business meets progressively higher performance targets. 
• Based on milestones, payments happen upon the accomplishment of specific operational goals. They can be anything from launching a new product to securing a major customer or expanding into a new market.

Key Components of Earnout Payment

• Contingent payment obligation. The core feature is that the buyer agrees to pay the seller additional amounts (the “earnout”) if specified performance conditions are met within a defined period.
• Performance metric(s) and target. The agreement must specifywhat is being measured (e.g., revenue, EBITDA, gross margin, customer count, or IRR) and the target level that triggers the earnout.
• Calculation method and formula. Here, the parties define the formula for converting the measured performance into a dollar amount or percentage of consideration (for example, “X% of revenue above Y” or “Z times EBITDA above a threshold”).
• Control and conduct provisions. To protect the seller, the agreement usually limits how the buyer can manage the business during the earnout (e.g., capital-spending floors, staffing levels, or marketing budgets).
• Dispute resolution and measurement framework. The earnout includes a defined basis of preparation (accounting standards or “earnout accounts”) and procedures for calculating the metric, often with a pro forma or worked example.
• Triggers and caps. Some earnouts have “step” or tiered structures (different payouts at different thresholds), upside caps, or flooring mechanisms (e.g., claw-backs or minimum performance levels).

Determining the Earnout Period After Business Sale

The earnout period is the window of time used to measure how the business performs after it’s sold. It needs to be long enough to give a fair picture of the company’s true results.

An earnout in a business sale can be as short as one year to as long as five years. The duration would depend on the business type and metric/milestone. Companies with steady, long-term growth patterns may need a longer period to show consistent performance, while faster-moving businesses might only need a year or two. The point here is to decide on a timeframe that’s fair for the sell side and buy side and accurately reflects how the business really performs over time.

Performance Metrics in Earnouts

Common Performance Metrics for Earnouts:

• EBITDA-Based
• Revenue-Based
• Milestone-Based
• Gross Profit-Based
• Customer Retention

How Metrics Impact Eanout Payments

Metrics meeting specific thresholds to trigger seller payments is the basis of an earnout. Both parties can agree on financial targets like revenue or EBITDA, or milestones, with calculations ranging from fixed sums to scaled amounts based on performance levels.

Earnout payments activate only when metrics hit their targets. If the company is not able to hit them, the seller won’t get paid or will only receive partial compensation. Fixed structures pay a set amount upon achieving goals, while variable ones scale up if thresholds are exceeded.

Aligning Buyer and Seller Goals

Complex formulas for business sale earn out are often the source of disputes, because they leave room for interpretation, especially in the way metrics are calculated after the deal closes. The buy side and sell side may clash over revenue recognition timing or allowable expense deductions. Fix this via spelled-out calculation rules within the definitions of the agreement.

Risk Management in Earnouts

Identifying Risks in Earnout Agreements

Earn-outs on business sales often introduce risk because both buyers and sellers have biases in how performance targets are measured. The seller wants to ensure that the business’s post-sale performance is evaluated fairly, while the buyer may be cautious about overpaying if results appear inflated. Objectivity cannot be achieved if either side performs the review.

The solution is to involve a neutral third party, typically an accountant outside of both parties, to perform the following functions:

• Oversee and verify the earnout calculations. 
• Apply consistent accounting standards.
• Confirm the accuracy of reported metrics.
• Ensure both sides have equal access to the financial records relevant to the earnout.

This impartial oversight can be viewed as fair for both parties. It also removes the suspicion that one side might manipulate the numbers to its advantage.

Mitigating Risks through Seller Financing

Weighing the risks is just part of any business deal. For those who don’t want the risks that come with earnouts (e.g., unpredictable performance, accounting manipulation, and loss of operational control), seller financing is an option for a more stable, secured, and predictable payment structure.

On the flip side, seller financing caps the seller’s potential gains since the buyer is bound only to the predetermined payments. Put differently, should the business thrive financially after the sale, the seller misses out on any upward adjustment to the purchase price.

Best Practices for Risk Management

• Convert contingent debt to fixed debt. Unlike earnouts, which depend on future performance, seller notes function as a loan with a fixed repayment schedule. This eliminates the risk of missing a payout due to “bad luck” or poor management by the buyer.
• Secure the debt with collateral. While earnouts are typically unsecured, seller financing allows you to secure a lien on business assets (e.g., inventory, equipment) or real estate. You can perfect this interest by filing a UCC-1 Financing Statement.
• Require personal guarantees. Mitigate the risk of buyer default by requiring the buyer’s principals to personally guarantee the financed amount, providing recourse against their personal assets.
• Use adjustable or forgivable seller notes. For risks like customer concentration, overpricing, or falling revenues, sellers can offer a note that’s forgiven or reduced. Unlike earnouts, which add to the purchase price when targets are achieved, a forgivable seller note protects the buyer by lowering the effective price if results do not hold after closing.

Business Valuation and Earnouts

Drafting an Effective Purchase Agreement

Key Clauses to Include

• Chosen earnout payment structure
• Earnout period after business sale and the timing of the payments
• Performance metrics and which goals to hit
• Tax treatments
• Legal considerations
• Dispute resolution
• Operation Controls
• Reporting
• Non-compliance implications

Negotiation Tips for Buyers and Sellers

• Both parties should agree on specific, measurable benchmarks. Revenue-based metrics (e.g., ARR or MRR) are often preferred for their transparency and resistance to manipulation.
• Earnout periods typically range from one to three years. Periods longer than three to five years are generally cautioned against due to increased uncertainty.
• Precise definitions of accounting methodologies are necessary for avoiding post-close disputes over how metrics like “Adjusted EBITDA” are calculated.
• Include clear mechanisms for mediation, arbitration, or third-party audits to handle disagreements without immediate litigation.

Avoid Common Pitfalls in Earnout Agreements

Issues like vague performance metrics, ambiguous contract terms, or allegations of misrepresentation during deal negotiations are bound to cause disputes. They happen when the agreement leaves room for interpretation and can quickly spiral into costly legal battles.

Avoid these complications by stipulating performance targets that are objective, transparent, and clearly measurable. Make the contract language precise and unambiguous, and clearly state how outcomes will be assessed and disputes resolved.

FAQs

Are earnouts common?

When you look into “earn out business sale,” you’ll notice that they are not especially common in smaller, “main street” business sales, but they show up much more often in mid‑market M&A deals where buyers and sellers are trying to bridge valuation gaps. In many of those transactions, the earnout can represent a meaningful slice of consideration—sometimes up to roughly a quarter of the agreed purchase price—provided the seller later hits clearly defined performance targets.

How are earnout payments treated in accounting?

In financial reporting, earnout obligations are generally split between compensation cost and purchase consideration, depending on what conditions trigger the payments. When the seller must remain employed and provide post‑closing services to receive the contingent amounts, those payments are viewed as compensation under GAAP and are expensed over the required service period. If, instead, the seller is entitled to the earn out payable based solely on how the acquired company performs after closing, and not on continued employment, the amounts are treated as additional purchase consideration.

That distinction drives accounting. A liability for the expected earnout must be recorded on the balance sheet, but payments characterized as compensation are recognized through the income statement as an operating expense, while amounts characterized as purchase price are initially recorded at fair value as contingent consideration and then remeasured or adjusted in line with the applicable acquisition‑accounting rules.

What is a typical earn-out percentage?

A “typical” earn‑out is usually a minority slice of the deal value, but it varies by industry and risk profile.

In most traditional businesses, buyers and sellers often tie roughly 10%–25% of the purchase price to post‑closing performance targets over a one‑ to three‑year window. In contrast, deals involving high‑growth tech or service companies sometimes push the contingent piece much higher, with earn‑outs reaching 60%–80% of the overall consideration when future performance and scalability are major drivers of value.
