Sellers talk in headline numbers, and so do cocktail parties — "they paid 3.5×." But a headline price is an accounting fiction the moment any of it is deferred, because it treats a contingent earnout dollar and a wired cash dollar as equal, and they are nothing alike. The vanity-versus-sanity framework is simply the habit of refusing that fiction: decompose every offer into its components, discount each to what it's really worth today, and negotiate on the total that results.
§ 01 · The gapVanity sums, sanity discounts.
| Component | Sanity value (% of face) |
|---|---|
| Cash at closing | 100% — no discount |
| Seller note | 90–100% at market rates |
| Rollover equity | 80–95% of the closing valuation |
| Earnout | 30–60% — expected value |
The vanity headline aggregates each component at face value; the sanity number discounts each to its risk-adjusted present value, and the difference is a 10–30% gap on a typical deal. The four components discount very differently. Cash at closing is worth 100% of face — there's nothing to discount. A seller note is worth 90–100% of face at market rates: a 5% coupon against an 8% market rate prices to roughly 90–93% of face. Rollover equity is worth 80–95% of the closing valuation. And an earnout is worth only 30–60% of face on an expected-value basis — by far the steepest discount. Run a $3M headline through this and it can resolve to about $2.69M of sanity value: $1.5M cash + a $600K seller note at 5% (~$550K present value) + a $600K earnout over three years (~$338K expected) + $300K rollover (~$298K) — a 10.3% discount on a relatively cash-heavy deal. The earnings that headline is built on are themselves negotiated in the pro-forma EBITDA framework.
§ 02 · Why the earnout discounts hardestFour stacked risks.
An earnout discounts to 30–60% of face because four risks stack on it: performance risk (was the metric achieved?), measurement-dispute risk (is the seller's reporting accepted?), counterparty risk (is the buyer solvent at payment time?), and time value (payments are one to five years out). Each year's payment carries its own probability and its own discount — Year 1 at ~74% of face, Year 3 at ~40% — and the combined expected-value-to-face lands in that 30–60% band.
The earnout earns its steep discount honestly, because four distinct risks stack on it. Performance risk: did the metric actually get hit? Measurement-dispute risk: will the seller's reporting be accepted, or fought over? Counterparty risk: is the buyer still solvent when payment comes due? And time value: the payments land one to five years out. Year by year, the math compounds — a high-probability Year 1 payment (80% likely, discounted one year at 8%) is worth ~74% of face; a moderate Year 2 (65%) ~55%; a lower Year 3 (50%) ~40% — and the combined expected-value-to-face lands in the 30–60% band. The seller note discounts far less (90–100%) because it's contractual debt, not contingent on performance, and rollover discounts less than the earnout (80–95%) because it carries governance, capital-appreciation exposure, a tag-along/drag-along liquidity path, and no single make-or-break metric. Understanding why each component discounts the way it does is what turns the framework from a number into a negotiating tool. The earnout's own design choices are detailed in structuring the earnout.
§ 03 · Structure as a leverFour strategic moves.
Once you can compute sanity value, structure becomes a lever you pull deliberately, and four moves open up. Structure trade-off: offer a higher headline with more back-loaded components in exchange for a lower sanity price — the seller gets a bigger number to talk about, you pay less in real terms. Sanity-for-sanity comparison: show a seller where your offer delivers more real value at a lower headline than a competitor's. Component substitution: swap cash for a seller note or rollover at their appropriate discounts, freeing cash without raising real cost. Earnout structuring for realistic achievement: design an earnout the seller will actually hit 70%+ of the time, which raises its sanity value (less discount) and makes it a more credible part of your offer. The framework even leaves three things deliberately uncaptured — control and continuity value (a rollover-heavy lockup), the option value in a seller note's offset rights (worth an extra 5–10%), and tax-treatment differences (a pre-tax view is enough for most decisions; a full tax overlay matters only for unusual deals). Naming what the math doesn't capture is part of using it honestly.
§ 04 · Three disciplinesHow to never overpay on vanity.
Three disciplines turn the framework into habit. Decompose every offer — never evaluate a headline in isolation; break it into its four components and discount each. Compare offers on sanity, not vanity — the offer with the bigger headline is frequently the worse deal once the earnout and back-loading are discounted. And use structure to pay less for the same sanity value — the whole point of understanding the discounts is to engineer an offer that's generous on paper and disciplined in reality. The rule of thumb to carry: headline multiples typically overstate true value by about 30% once liquidity discounts and probability adjustments are applied, and a seller anchored on a cocktail-party vanity multiple is consistently mis-pricing. Negotiate on sanity, structure on sanity, and you'll win deals at headlines that look generous to the seller and prudent to you — which is exactly the kind of deal worth doing. The component menu these disciplines work across is in payments over time.

Terminology on this shelf
- Vanity price
- The headline — every component summed at face value, as if deferred dollars equal today's dollars.
- Sanity price
- Each component discounted to risk-adjusted present value — 10–30% below the headline.
- Component discounts
- Cash 100%, seller note 90–100%, rollover 80–95%, earnout 30–60% of face.
- Four earnout risks
- Performance, measurement dispute, counterparty, and time value — why the earnout discounts hardest.
- Structure trade-off
- A higher headline with back-loaded components for a lower sanity price — generous on paper, disciplined in fact.
- The 30% rule
- Headline multiples typically overstate true value by ~30% once liquidity and probability are applied.
