SDE (Seller's Discretionary Earnings) and EBITDA are two ways of measuring a business's normalized earnings — SDE is used to value smaller, owner-operated businesses, and EBITDA is used as a business grows large enough to run with a management layer the owner doesn't personally fill. The number a buyer applies your multiple to is rarely the profit on your tax return. It's a normalized earnings figure — and whether that figure is SDE or EBITDA changes both the number and the multiple. This guide explains the difference, where the crossover happens, and why the same business can look very different under each.
What is SDE (Seller's Discretionary Earnings)?
Seller's Discretionary Earnings is your net profit, with the owner's salary and discretionary personal expenses added back. The logic is simple: a buyer of a small, owner-operated business is stepping into the owner's seat, so the total financial benefit available to a single owner-operator is what matters.
A typical SDE build-up starts from net income and adds back: one owner's salary and payroll taxes, owner perks run through the business (vehicle, travel, personal insurance), interest, taxes, depreciation, amortization, and any genuine one-time expenses.
SDE answers the buyer's question: "If I run this myself, how much total benefit does it produce?"
What is EBITDA?
EBITDA — earnings before interest, taxes, depreciation, and amortization — measures the operating profitability of a business that runs with a management structure in place. Crucially, EBITDA does not add back a market-rate salary for the role the owner fills, because a larger business is expected to pay someone to do that job.
EBITDA answers a different question: "After paying a manager to do what the owner does, how much profit is left for an investor?" That's why a buyer using EBITDA effectively subtracts a market salary that an SDE buyer adds back.
SDE vs. EBITDA: the difference in one table
| SDE | EBITDA | |
|---|---|---|
| Used for | Owner-operated businesses (usually < ~$1–2M earnings) | Larger businesses with a management layer |
| Owner's salary | Added back (one owner) | Not added back — a market-rate manager salary is assumed |
| Typical buyer | Individual / owner-operator, search funds | Private equity, strategics, financial buyers |
| The question it answers | "What's the total benefit if I run it?" | "What's left for an investor after paying management?" |
| Effect on the number | Higher reported earnings | Lower earnings, but applied to a higher multiple |
Where the crossover happens
Most businesses are valued on SDE while they're small and owner-run, and shift to EBITDA as they approach and cross roughly $1–2 million in earnings. There's no hard line — it's about whether the business runs through a management layer or through the owner. A $900K-earnings business that already operates without the owner may be valued on EBITDA; a $1.5M business where the owner is still the operator may still be valued on SDE.
This matters because the two methods carry different multiples. SDE multiples for small businesses commonly run ~2x–4x; EBITDA multiples for businesses in the lower middle market commonly run ~3x–6x. You can't compare a "3x" across the two without knowing which earnings base it's applied to.
Why the same business looks different under each number
Consider a services business: $1.4M revenue, $300K net income, with the owner taking a $130K salary plus ~$30K in personal expenses run through the company.
- Under SDE: $300K + $130K + $30K = $460K SDE. At a 3x SDE multiple → ~$1.38M.
- Under EBITDA: the owner does real work, so a buyer subtracts a ~$120K market manager salary. EBITDA ≈ $340K. At a 4.5x EBITDA multiple → ~$1.53M.
Same business, two valid methods, different answers — and the gap widens or narrows depending on how owner-dependent the business is. The less the business needs the owner, the more EBITDA (and the higher multiple) works in your favor. (How owner dependency moves your multiple →)

Which number should you watch?
If you're under ~$1M in earnings and run the business yourself, track SDE — that's what your likely buyer uses. If you're approaching or above $1–2M, or your business already runs through managers, start thinking in EBITDA, because that's the lens a private equity or financial buyer will apply. Either way, the highest-leverage move is the same: build a business that needs you less, so the EBITDA lens — and its higher multiple — works for you instead of against you.

Frequently asked questions
Is SDE or EBITDA higher?
SDE is almost always the higher number, because it adds back the owner's full salary and personal expenses, while EBITDA assumes a market-rate manager salary is paid. The trade-off is that EBITDA is typically applied to a higher multiple.
At what size do buyers switch from SDE to EBITDA?
The shift usually happens as a business approaches $1–2 million in earnings, or sooner if the business already runs through a management layer rather than the owner.
What counts as an add-back in SDE or EBITDA?
Common add-backs include the owner's above-market salary, owner perks (vehicle, travel, personal insurance), interest, taxes, depreciation, amortization, and genuine one-time costs. Whether each survives a buyer's review depends on documentation. (Add-backs that survive diligence →)
Do private equity buyers use SDE?
Rarely. Private equity and financial buyers almost always value on EBITDA, because they're buying an investment that pays management, not a job they'll personally run.
