What an earnout is
An earnout is deferred, conditional consideration. Part of the purchase price is paid at closing; the rest is paid over a future period only if the business meets defined milestones — revenue, profit, retention, product, or integration targets, depending on the deal.
Earnouts exist to bridge a gap in how buyer and seller value the business. The buyer pays more only if the optimistic case materializes; the seller gets a shot at full value by delivering on it. That alignment is useful, but it means a portion of your 'proceeds' is genuinely uncertain until the conditions are met.
Confirmed vs. contingent: the core distinction
The single most important discipline after a sale is to separate what's confirmed from what's contingent. Confirmed proceeds — cash received at closing, net of taxes and obligations — are actually yours. Contingent proceeds — the earnout, any escrow holdbacks, deferred notes — are a claim that may or may not pay out, in part or in full.
Blending the two is how people get hurt. If you set your lifestyle, giving, or new investments against the full deal value and the earnout underperforms, you've over-committed against money that never arrived. Plan your baseline against confirmed proceeds only, and treat contingent payments as upside that improves the plan when (and if) it lands.
Why earnouts often pay less than expected
Earnout targets are frequently missed — not always because of failure, but because conditions change. After a sale, the new owner controls the business: priorities shift, integration disrupts operations, and the metrics the earnout depends on may no longer behave as they did under your ownership.
Disputes over how targets are measured are common, and the structure of an earnout can create misaligned incentives during the payout period. None of this means earnouts are bad — they're a normal deal tool — but it's exactly why a prudent plan never assumes the contingent piece as baseline income.
Building a plan that survives either outcome
The goal is a plan that is comfortable on confirmed proceeds alone and simply better if the earnout pays. A few principles owners commonly use:
- Anchor your lifestyle and essential spending to confirmed, after-tax proceeds — never to the headline deal value.
- Model the earnout as a probability-weighted upside, kept visibly separate from your confirmed floor, not folded into net worth.
- Plan for the taxes on both pieces, which can fall in different years and be taxed differently depending on the deal's structure.
- Address the concentration you may now have: a single large cash sum still needs to be invested with the same diversification discipline as any other windfall.
- Revisit the plan as earnout milestones resolve, moving money from 'contingent' to 'confirmed' only when it actually arrives.
The honest test
Ask the simple question: if the earnout paid nothing, would your plan still hold? If the answer is yes, you've planned correctly and any earnout payment is pure upside. If the answer is no, you've quietly committed to money you don't yet have — and a missed target becomes a personal financial problem, not just a smaller bonus.
