SDE and EBITDA are both measures of a business's true earnings, but SDE (Seller's Discretionary Earnings) adds back the owner's salary while EBITDA does not. As a rule, buyers use SDE to value small owner-operated businesses, typically those with under about 1 million USD in earnings, and switch to EBITDA for larger companies that run with a management team in place. Choosing the wrong measure can misstate value by a wide margin, so understanding the difference is the first step in any valuation.
What EBITDA is
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. You start with net profit and add back those four items to strip out financing decisions, tax situations, and non-cash accounting charges, leaving a cleaner picture of operating performance.
The formula is straightforward:
- Net profit
- plus interest
- plus taxes
- plus depreciation
- plus amortization
- equals EBITDA
Crucially, EBITDA assumes the business already pays a market-rate salary to whoever runs it. It measures what the company earns as an operating entity, independent of any single owner. That is why it suits larger businesses where the buyer inherits a team and expects to keep paying managers.
What SDE is
Seller's Discretionary Earnings takes EBITDA a step further and adds back one owner's total compensation and benefits, plus discretionary and one-time expenses. The idea is to show a prospective owner-operator the full economic benefit they would receive by running the business themselves.
A typical SDE build looks like this:
- Net profit
- plus interest, taxes, depreciation, and amortization (the EBITDA add-backs)
- plus one owner's salary and benefits
- plus personal or discretionary expenses run through the business
- plus documented one-time costs
- equals SDE
Because SDE includes the owner's pay, it is always a larger number than EBITDA for the same business. That is by design: a small-business buyer is buying a job plus a profit, so the earnings measure reflects both.
The core difference in one line
| SDE | EBITDA |
|---|---|
| Adds back one owner's salary | Assumes a market-rate salary is already paid |
| Used for small owner-run businesses | Used for larger, management-run companies |
| Larger figure for the same business | Smaller figure for the same business |
| Multiples typically 2x to 4x | Multiples typically 3x to 6x, higher for large firms |
Why the multiples differ too
Because SDE and EBITDA are different-sized numbers, they carry different multiples, and mixing them up is a common and expensive mistake. SDE multiples for small businesses commonly run 2x to 4x. EBITDA multiples run higher, roughly 3x to 6x for smaller companies and 8x to 12x or more for larger, higher-quality ones. Applying an EBITDA multiple to an SDE figure, or the reverse, produces a value that is badly off. Pick the measure that fits your size, then apply the matching multiple. If you are working out your own figure, our step-by-step guide to how to calculate SDE covers which add-backs hold up and which ones buyers reject, and you can run the numbers with the SDE multiple or the EBITDA multiple valuation method.
A worked example
Consider a business with 500,000 USD in revenue and 90,000 USD in net profit, where the owner also takes a 70,000 USD salary and runs 10,000 USD of personal expenses through the company.
- EBITDA might be roughly 90,000 USD plus a small amount of depreciation, say 100,000 USD.
- SDE adds the 70,000 USD salary and 10,000 USD of personal expenses, reaching about 180,000 USD.
At a 3x SDE multiple, the SDE view estimates around 540,000 USD. At a 5x EBITDA multiple, the EBITDA view estimates around 500,000 USD. The two land in a similar range precisely because the correct multiple is paired with the correct earnings base. That reconciliation is the heart of a sound estimate.
Which one should you use
Use SDE if the business is small and owner-operated, where the buyer will step in and run it. Use EBITDA if the business is larger, has a management team, and would keep running without the current owner. A rough boundary is around 1 million USD in earnings, though industry norms and buyer type matter more than any hard line. Buyers who benchmark against comparable sales will naturally use whichever measure the comp deals were priced on.
Estimate, not appraisal
Whether you use SDE or EBITDA, the resulting figure is an educational estimate to guide planning and negotiation, expressed as a range rather than a fixed value. A formal valuation for tax, legal, or lending purposes should come from a credentialed appraiser who can issue a defensible signed report.
