This post is a fast, checklist-style answer to when to use SDE vs. EBITDA — for the full explanation of what each metric measures and why, see our complete SDE vs. EBITDA comparison. This version is meant to be scanned, not read start to finish.

  • The decision comes down to two questions: who runs the business day to day, and how large is it?
  • SDE fits owner-operated businesses under roughly $2 to $3 million in earnings.
  • EBITDA fits businesses run by a management team, generally above that threshold.
  • Management structure matters more than the exact earnings number when the two disagree.

Use SDE If:

  • You personally work in the business and make most day-to-day decisions.
  • Your earnings are under roughly $2 million to $3 million.
  • A buyer would be replacing you personally, not a management team.
  • You want the valuation to reflect the full economic benefit of ownership, including the value of your own role.

Use EBITDA If:

  • The business is run by a general manager or leadership team, not you personally.
  • Earnings exceed roughly $2 million to $3 million.
  • A buyer would be acquiring a management structure, not stepping into your job.
  • You're comparing your business against larger, professionally managed acquisition targets.

What If You're Right at the Threshold?

Let management structure decide, not the earnings number alone. A $2.5 million business still entirely dependent on the owner is usually better valued on SDE, even above the typical threshold, since a buyer is still effectively replacing that owner's role. See our guide to business valuation multiples by industry for how the multiple side of the equation changes once you've picked the right metric.

What Happens If You Use the Wrong One?

You'll misjudge your value in either direction — SDE multiples and EBITDA multiples aren't interchangeable, so using the wrong metric with the wrong multiple compounds the error rather than canceling it out. This confusion is easier to fall into than it should be, in part because the SEC classifies EBITDA as a non-GAAP measure with no single mandated calculation — so a number labeled "EBITDA" from one source isn't guaranteed to match another's. If a buyer or broker quotes you a number, confirm which metric it's based on and how it was calculated before comparing it to anything else.

What Should You Do Next?

Once you know which metric applies, get an actual calculation done rather than estimating — see our EBITDA valuation calculator walkthrough or our guide to getting a business valuation done for a real number.

FAQ

1. What's the quick rule for choosing SDE vs. EBITDA?

If you personally run the business day to day and it earns under roughly $2 to $3 million, use SDE. If it's run by a management team and earns more than that, use EBITDA.

2. What if my business is right at the $2 to $3 million threshold?

Base the decision on management structure, not just earnings — a business at that size still run entirely by the owner is usually better valued on SDE despite the earnings level.

3. Can a buyer and seller disagree on which metric to use?

Yes, and it's worth resolving early — using the wrong metric changes both the earnings base and the appropriate multiple, so the disagreement compounds rather than cancels out.

4. Does industry affect whether I should use SDE or EBITDA?

Not directly — the decision is driven by business size and management structure, not industry, though industry does affect which multiple gets applied once you've picked the right metric.
