SDE vs. EBITDA: The Valuation Metric That Determines Your Exit Multiple

Two companies. Same revenue. Same bottom-line cash flow. One exits at $6.1M, the other at $8.05M. The difference is which metric you use — and which buyer you’re talking to.

The Number

The example is hypothetical but the mechanics are real. A software company generating $1.5M in annual cash flow runs through both models:

Under SDE (Seller’s Discretionary Earnings), add back the founder’s $250K salary and discretionary expenses, arriving at an earnings base of $1.75M. Apply a 3.5x multiple typical for owner-operated businesses: enterprise value of $6.1M.

Under EBITDA for the same company — where founder compensation is treated as an operational expense requiring market-rate replacement — the earnings base drops to $1.15M. But institutional buyers apply higher multiples to manager-independent businesses: 7.0x produces an enterprise value of $8.05M.

Both models are describing the same business. The gap reflects structural differences in buyer expectations, not accounting games.

How the Math Works

SDE adds back everything that benefits the current owner uniquely: the owner’s salary, personal expenses run through the business, and one-time costs. The resulting number answers a specific question — “How much cash flow is available to the incoming owner, assuming they operate it themselves?” That framing maps to individual buyers: searchers, small family offices, lifestyle business acquirers.

EBITDA treats the founder as a replaceable input. The salary stays in as a real cost, because the buyer isn’t planning to operate it themselves — they’re buying a company that needs to run without the current owner. The higher multiple reflects confidence in the business’s independent operation, not just its raw cash generation.

The acquisition market for small business and SaaS companies has clear structural demarcations: below $2M enterprise value, SDE is the dominant expectation; $2M–$5M is a transition zone where the business’s organizational maturity determines which metric applies; above $5M, EBITDA is the professional acquirer’s default. Applying SDE logic when talking to a private equity buyer signals a category mismatch that undermines negotiating credibility before terms are discussed.

What It Signals

The metric mismatch problem cuts both ways. A founder using EBITDA framing below $2M enterprise value often undersells by making the business look less attractive to the actual buyer pool. A founder using SDE framing above $5M looks like they haven’t prepared for institutional diligence — which affects not just the headline multiple but the terms, rep/warranty requirements, and earn-out structure.

Flippa’s analysis recommends preparing dual-track financials — both SDE and adjusted EBITDA — before entering a sale process, specifically to avoid being caught recalculating during diligence when the buyer’s financial model doesn’t match yours.
