Earnout Expected Value Calculator
Calculate the probability-weighted value of earnout tranches and risk adjustments.
Earnouts are contingent payments tied to future performance after closing. They're common in acquisition deals but often overestimated by sellers. A $2M earnout sounds great until you realize the targets might not be achievable or the buyer controls the metrics. Understanding the real expected value of an earnout requires modeling probability and discounting future cash.
This calculator helps you understand what earnouts are actually worth in today's dollars. It accounts for the probability you'll hit the targets, the discount rate reflecting risk and time value, and the payment schedule. By comparing the present value to what you could get as an upfront payment, you can negotiate more strategically.

Risk & Timing
How Earnout Expected Value Works
Earnouts are risky because they depend on future performance. If your business is valued at 8x EBITDA and the buyer offers a $2M earnout if you hit 10% growth, your actual expected value depends on the probability of hitting that target. If you think it's 80% likely, the expected value is $1.6M, not $2M. Discounting for time value further reduces it.
Setting Realistic Earnout Targets
The biggest earnout mistake is agreeing to targets you can't control or that depend on the buyer's actions. If the earnout depends on the buyer retaining customers or reaching new markets, you have no control over success. Realistic targets depend on your recent performance trend, market conditions, and the buyer's commitment to growth. Conservative founders should discount probability estimates significantly.
Earnout Versus Cash
Always compare earnout expected value to upfront cash you could negotiate instead. A $2M earnout with 60% probability is worth $1.2M in expected value, less any discount rate. You might negotiate for $1.5M less in headline price but with full cash at close. The cash is certain; the earnout is risky. Conservative sellers prefer less upfront certainty.
Common Mistakes
Overestimating earnout probability
Founders are optimistic about hitting earnout targets. Be conservative in your probability estimates. If you've never hit 40% growth, don't assume you will post-close. Discount your historical performance trend by 10-20% to account for integration challenges.
Underestimating discount rate
A $1M earnout paid in two years is worth less than $1M today due to time value of money and risk. Use a 15-25% discount rate depending on business stability. For volatile businesses, use 25-30%.
Focusing on headline value instead of expected value
Earnout size is irrelevant if the probability is low. A $5M earnout with 20% probability is worth $1M in expected value. A $2M cash bonus is better.
