SDE vs EBITDA
Also known as: Seller's Discretionary Earnings, SDE, owner benefit
SDE is EBITDA plus one full-time owner's total compensation, used to price owner-operated small businesses, while EBITDA assumes management is a paid expense.
Seller’s Discretionary Earnings (SDE) and EBITDA are two ways of stating the same thing: the recurring cash a business throws off. They differ on a single assumption, and getting that assumption wrong is one of the most common ways a first-time buyer overpays.
SDE is the number business brokers quote on main-street listings. It takes adjusted EBITDA and adds back the total compensation of one full-time owner-operator: salary, payroll taxes, benefits, and any perks the owner runs through the business. The logic is that a new owner-operator will step into the seller’s role, so the seller’s pay is really discretionary income available to whoever runs the shop. EBITDA makes the opposite assumption. It treats a market-rate manager as a real, ongoing expense, because larger businesses are bought to be run by hired management, not by the buyer personally.
The single owner add-back is the whole difference
SDE equals adjusted EBITDA plus one working owner’s full compensation. The word one matters. The classic broker inflation trick is adding back the compensation of two or three working owners, or a working spouse, to fatten the earnings figure. Each of those people fills a role the buyer will still have to pay for, so only a single owner’s pay belongs in SDE. Everything else in the calculation is ordinary EBITDA add-back discipline: one-time costs and genuinely personal expenses come out, real operating costs stay in.
Which metric fits which deal
Owner-operated, main-street businesses price on SDE multiples, because the buyer is buying a job plus a return. Businesses large enough to carry a management layer price on adjusted EBITDA multiples, because the earnings already absorb the cost of running the place. The dangerous ground is the crossover zone in the lower middle market, where a business is transitioning from owner-run to management-run and either metric can be argued. That is exactly where mispricing happens.
Why the metric you pick changes the price
Take one business and describe it two ways. Its SDE is larger than its EBITDA by the amount of the owner’s pay. SDE multiples are correspondingly lower than EBITDA multiples, precisely because SDE includes a salary that a hired manager would consume. The error is mixing the two: apply a low SDE multiple to the larger SDE figure and you get a fair price, but apply an SDE-style multiple to an EBITDA-sized number, or an EBITDA multiple to an SDE-sized number, and you overpay. The multiple and the earnings base have to speak the same language.
Converting SDE to EBITDA
A buyer who wants to compare a main-street listing against private-equity-style comps converts SDE to EBITDA by subtracting the market-rate replacement compensation for the owner’s actual role. If the owner truly works full time running operations, that full salary comes out; if the owner is semi-absent, only the cost of the hours they really contribute does. A rigorous quality of earnings analysis makes that replacement-cost judgment explicit rather than leaving it buried in a broker’s add-back schedule.
Frequently asked questions
- When should I use SDE instead of EBITDA?
- Use SDE for owner-operated, main-street businesses where the buyer will personally step into the owner’s role, since the owner’s pay is really return to the new operator. Use EBITDA once the business is large enough to run on hired management, because the earnings should already carry the cost of that management. In the crossover zone, run both and understand which assumption each one makes.
- Why is the SDE multiple lower than the EBITDA multiple?
- Because SDE is a larger number than EBITDA for the same business: it adds one owner’s full compensation back into earnings. A metric that includes a manager’s salary has to be capitalized at a lower multiple to reach a comparable value. If you apply an EBITDA-style multiple to an SDE figure, you double count the owner’s pay and overprice the deal.
