SDE vs EBITDA: Which Earnings Metric Prices the Deal

What each metric actually measures

SDE — Seller's Discretionary Earnings answers: if I buy this business and work in it full time, what is the total financial benefit available to me before debt service and taxes? It starts at net profit and adds back interest, taxes, depreciation, amortization, one owner's total compensation and benefits, and non-recurring or genuinely personal expenses run through the company.

EBITDA — Earnings Before Interest, Taxes, Depreciation and Amortization answers: what does this business earn as a standalone operation, with management paid at market rate? Everything SDE adds back is added back except the owner's compensation, which stays in as a real cost of running the company.

The gap between them is, essentially, one market-rate salary. That is not a rounding difference — on a business earning $400,000 of SDE with a $110,000 management role, EBITDA is $290,000, roughly 27% lower.

The same business, both ways

Take a distribution business with $2.4M of revenue and these figures: net profit $185,000; owner's salary $120,000; owner's health insurance and auto through the company $22,000; interest $34,000; depreciation $48,000; a one-time legal settlement of $27,000.

SDE = 185,000 + 120,000 + 22,000 + 34,000 + 48,000 + 27,000 = $436,000.

EBITDA = the same total minus market-rate management compensation. If a competent general manager for this business costs $115,000 fully loaded, EBITDA is roughly $321,000.

Now the multiples. Owner-operated businesses of this size commonly trade in a range of roughly 2x to 4x SDE, depending on industry, growth, customer concentration, and how transferable the owner's role is. Lower-middle-market companies priced on EBITDA typically command higher multiples — frequently 4x and up — precisely because they come with management in place.

At 3.0x SDE, this business is about $1.31M. At 3.0x EBITDA, it is about $963,000. Same company, same month, a $350,000 spread — created entirely by which line the multiple was applied to. If a seller quotes an EBITDA-scale multiple against an SDE-scale earnings figure, the overpay is baked in before diligence starts.

Where the boundary sits

There is no bright line, but the practical convention is straightforward. If the buyer will run the business day to day, SDE is the honest metric, because the owner's compensation is genuinely available to that buyer. If the business already has a manager, or is large enough that the buyer will hire one, EBITDA is the honest metric, because that salary is a permanent cost of ownership.

In practice, businesses with under roughly $1M of earnings are usually quoted in SDE and businesses above a few million in EBITDA, with an ambiguous band in between where both appear. The critical move as a buyer is to force clarity: ask which metric the asking price is based on, and ask for the calculation, line by line.

A useful test that cuts through the definitions entirely: after debt service, after paying whoever actually runs the business a market wage, and after the capital expenditure the assets genuinely require, what is left? That number does not care what anybody calls it, and it is the one your lender will care about.

Add-backs: where both metrics get inflated

Both figures rest on adjustments, and adjustments are where listings get optimistic. Defensible add-backs are expenses a new owner genuinely will not incur: the owner's personal vehicle, a spouse on payroll who does not work, a one-time legal settlement, a discontinued product line's costs, moving expenses from a completed relocation.

Add-backs to reject, or at minimum to interrogate: deferred maintenance dressed as a one-time cost, "one-time" expenses that appear in three consecutive years, marketing spend cut to fatten the year before sale, an under-market owner salary in an EBITDA calculation, and any adjustment that cannot be traced to a specific line in the general ledger. Ask for the tax returns alongside the P&L. Sellers optimize the P&L for buyers and the return for the IRS, and the difference between the two is informative.

Depreciation deserves a note of its own. Both metrics add it back, which is fine for a software business and dangerous for a trucking company or a laundromat. If the equipment genuinely wears out, subtract a realistic annual maintenance capital figure before you apply any multiple — otherwise you are paying for earnings that are going to be spent on replacement machines. Our laundromat and trucking company valuation pages work through exactly that adjustment.

How this changes your negotiation

Once you have both numbers, you have an argument rather than an opinion. When a seller asks for a multiple drawn from lower-middle-market comparables, the response is not "that is too high" — it is that those comparables are EBITDA multiples on companies with management in place, and this business has one owner doing four jobs. Either the price comes down to an SDE-scale multiple, or the seller stays on long enough for a manager to be hired and trained.

It also tells you which structures fit. A business with a wide SDE-to-EBITDA gap is one where the owner's personal involvement is most of the value, which argues for a longer transition, a real non-compete, and possibly an earnout tied to retention. Our negotiation playbook covers how to trade those terms against price, and the valuation guide covers building the multiple range itself.

The short version

SDE is the total benefit to a working owner. EBITDA is the profit of a business with management paid for. SDE is the larger number and carries the lower multiple; EBITDA is the smaller number and carries the higher one. Any quoted price is meaningless until you know which is which, and any add-back you cannot trace to the general ledger is a negotiating position rather than a fact.
