EBITDA
Definition
Profit before interest, taxes, depreciation, and amortization.
Why It Matters
Larger deals price on EBITDA multiples rather than SDE, and the two never compare because EBITDA already subtracts a market manager's pay. So the first question on any listing is which measure the multiple is built on, since putting an SDE multiple against an EBITDA business overpays by a full salary's worth of earnings.
In numbers: A business showing $510k of SDE would show about $360k of EBITDA after paying a $150k manager to replace the owner, which is why an SDE multiple and an EBITDA multiple are never comparable.
