The earn-out is the dominant pricing instrument for M&A deals where seller and buyer disagree on valuation. It splits the price into upfront cash + variable component tied to post-closing performance. This calculator shows how the structure affects total expected value, after-NPV discounting and comparison vs all-cash deal.

How earn-out works in M&A
Earn-out structure splits the total deal price into two components: a fixed upfront cash payment at closing (typically 60-80% of total deal value) and a variable component paid over a period (typically 12-36 months) based on the company’s achievement of specific performance targets — most often EBITDA-based.
The mechanism aligns seller and buyer incentives: seller has incentive to support smooth post-closing transition (and is rewarded for it), buyer has protection against post-closing performance degradation. When achievement reaches 100% of target, seller receives full earn-out. When achievement falls below threshold, earn-out reduces or zero.
Reading the calculator results
Total NPV expected: combined value of upfront cash + earn-out discounted to present value. This is the realistic expected value to the seller, accounting for time value of money.
Upfront cash: amount received at closing. This is certain — no execution risk.
Earn-out nominal: gross amount payable if target is achieved at 100%. This is the headline number but not the realistic expected value.
Achievement: the percentage of EBITDA target you realistically expect to achieve in the earn-out period. Critical assumption — be honest with yourself.
vs all-cash: difference between total NPV expected and the upfront cash. Positive means earn-out structure is beneficial; negative means all-cash deal would have been better for seller.
FAQ
What discount rate should I use?
Industry standard for mid-market: 10-15% reflecting time value, execution risk, and counterparty risk. Higher risk profile (PE buyer with leverage, sector volatility) increases discount rate; lower risk (stable strategic buyer with strong balance sheet) reduces it.
What achievement % is realistic?
Industry data: realised earn-outs achieve 60-75% of target on average. Be skeptical of 100% projections from buyers or sellers — neither party has incentive to be realistic on this dimension.
How does earn-out compare to all-cash deals?
All-cash deal: 100% certainty on amount received, lower headline price typically. Earn-out: higher headline price, but realistic expected value (after achievement uncertainty and discounting) typically 5-15% above all-cash equivalent. Pattern depends heavily on achievement assumption.
What can buyers do to manipulate earn-out outcomes?
Post-closing buyer-side decisions can depress earn-out metrics: deferred investments, accounting policy changes, transfer pricing on inter-company transactions. Critical: SPA must include protections (management governance preservation, accounting standards preservation, seller veto on specific decisions).
Are earn-outs always taxed when actually received?
Yes for Italian sellers, allowing tax deferral. Variable portion taxed when received, not at signing. This is advantageous from a tax standpoint compared to all-cash deals taxed in full at signing.
