SDE vs EBITDA: Which One Actually Values Your Business?
SDE and EBITDA both measure your real earnings — but buyers use them differently, and picking the wrong one can misprice your business by a turn or more. Here's which applies to you.
Two buyers look at the same trade business and quote two different earnings numbers. One says "$560K," the other says "$450K." Neither is lying — they're using SDE vs EBITDA, and which one applies to you decides who your buyer is and what multiple they'll pay. Get the basis wrong and you can misprice the business by a full turn.
Here's the plain-English version, with a worked example.
SDE vs EBITDA: the one-line difference
Both start from your profit and add back the things that aren't really business costs. The difference is one line: the owner's pay.
- SDE (seller's discretionary earnings) adds back one owner's full compensation — salary, perks, the personal truck, one-time costs. It answers: "If I, an owner-operator, buy this and run it myself, how much does it throw off for me?"
- EBITDA does not add back a market-rate owner wage. It assumes the business pays a manager to do the owner's job, and counts only what's left. It answers: "If I drop in a hired GM, how much does the business earn on its own?"
So for the same company, SDE is the bigger number (it keeps the owner's pay) and EBITDA is smaller (it subtracts a manager to replace the owner).
The bridge, in real lines
This is how the offers.ai engine walks from reported profit to both numbers (its SDE / Buyer's-EBITDA bridge). Illustrative figures for an owner-run shop:
| Line | Amount |
|---|---|
| Reported pre-tax profit | $300,000 |
| + Owner's salary (added back) | $220,000 |
| + Owner perks & one-time costs | $40,000 |
| = SDE | $560,000 |
| − Market-rate manager to replace the owner | −$110,000 |
| = Buyer's EBITDA | $450,000 |
Same business. Two honest earnings numbers, $110K apart — entirely because of how each treats the owner's job.
Which one values your business?
It tracks with size and who the buyer is:
| SDE basis | EBITDA basis | |
|---|---|---|
| Typical earnings | under ~$1M | over ~$1M |
| Who's buying | individual / SBA-financed owner-operator | private equity, strategics, manager-run buyers |
| Why | the buyer will run it and pay themselves from SDE | the buyer installs management and underwrites on EBITDA |
| Multiple | lower (it's a bigger earnings base) | higher headline multiple, smaller base |
The trap is comparing the two multiples head-to-head. An SDE multiple and an EBITDA multiple are not the same currency — a "3× business" on SDE and a "5× business" on EBITDA can be worth nearly the same money, because the earnings bases differ. Always ask: a multiple of which number?
What it means in dollars
Take a trade where the engine prices EBITDA in a 3.0×–8.0× band — HVAC, for example. Put that on the ~$450K Buyer's EBITDA above and you get roughly $1.4M–$3.6M. Quote the same business on its ~$560K SDE at a main-street multiple and you land in a similar neighborhood — but only if you use the right (lower) SDE multiple. Use an EBITDA multiple on an SDE number and you'll talk yourself into a price no buyer will honor.
This is exactly where deals stall: the owner ran the math on SDE with a lower-middle-market EBITDA multiple, and the buyer's quality-of-earnings review quietly re-based everything.
Common mistakes
- Mixing the basis and the multiple. SDE earnings deserve an SDE multiple; EBITDA earnings deserve an EBITDA multiple. Never cross the streams.
- Adding back a full owner salary with nobody to replace you. If the business can't run without you, that salary is a real cost — a buyer subtracts it right back out to get EBITDA.
- Dressing up recurring costs as "one-time." Buyers see the pattern across three years. A cost that shows up every year isn't an add-back.
- Ignoring the manager-replacement line. The single biggest swing between SDE and EBITDA is what it costs to replace you. The more the business already runs without you, the smaller that line — and the higher your multiple.
The takeaway
SDE vs EBITDA isn't a trick question — it's a signal of who buys your business and how they'll price it. Smaller, owner-run shops sell on SDE to individuals; larger, manager-run ones sell on EBITDA to institutions. Know which one you are, match the multiple to the basis, and your add-backs will survive the diligence that re-checks all of it.
