A buyer-focused explanation of seller’s discretionary earnings, EBITDA, owner compensation, add-backs, and when each measure is useful.
A practical research brief from the Business Buyer Check learning library.
Who This Is For
Buyers reconciling price, normalized earnings, financing capacity, and downside exposure.

What SDE Includes
SDE usually begins with pretax profit and adds back interest, taxes, depreciation, amortization, one owner’s compensation and benefits, and supported discretionary or nonrecurring expenses. Definitions vary, so inspect the actual bridge.
What EBITDA Leaves in the Business
EBITDA does not automatically add back owner compensation. If the owner performs a necessary operating role, a buyer should include market replacement compensation before treating cash flow as available.
Why Conversions Fail
- Adding back multiple owners without adding replacement wages
- Calling recurring marketing, repairs, or payroll nonrecurring
- Ignoring rent changes after a related-party lease ends
- Comparing an SDE multiple with EBITDA transactions
The Buyer’s Practical Rule
Use the measure that matches the post-close operating model, then reconcile it to tax returns, payroll, bank activity, and the general ledger. Label every adjustment and keep seller-provided and buyer-accepted earnings separate.
Illustrative Buyer Example
How a Buyer Would Apply This Guide
A seller’s headline earnings support the asking price, but the supporting records are incomplete. The buyer follows this guide to identify the missing inputs, reproduce the calculation, request independent support, model the downside, and convert unresolved items into offer protections rather than treating the claim as verified.

Frequently Asked Questions
Is SDE the same as cash flow?
No. SDE is an adjusted earnings measure and does not automatically account for debt payments, taxes, working-capital needs, or future capital expenditure.
Can I convert SDE to EBITDA?
Often, but the conversion depends on owner compensation and required replacement labor. A mechanical subtraction can be misleading if the owner performs several roles.
Which is better for a small business acquisition?
SDE is often more intuitive for a single owner-operator. EBITDA is often more comparable for a business with management in place. The post-close model should determine the choice.
