Free SDE Calculator — find your true owner earnings
Seller’s Discretionary Earnings (SDE) is the number small-business buyers price from. This free SDE calculator walks through every standard add-back — owner salary, interest, depreciation, one-time costs, and personal expenses run through the business — and gives you the figure in about two minutes. The same math, with one tweak, also produces Adjusted EBITDA.

Find your true earning power
Start with pre-tax profit, add back the standard items, then layer in the normalizing adjustments a buyer would accept. The result updates as you type.
Your bottom-line profit before income taxes — the "net income before taxes" line on your P&L.
One-off legal or consulting fees, a single large repair, a move — costs that will not repeat for a buyer.
Personal auto, travel, meals, phone, or insurance paid by the business.
Charitable donations, sponsorships, or other discretionary spending a buyer would not continue.
See what that's worth
Established businesses sell for roughly 3 to 5 times Adjusted EBITDA. Run your number through the valuation calculator, or get a real figure on a call.
This is an estimate to help you prepare, not a formal financial statement. A buyer will confirm add-backs against your tax returns and books. The calculator runs entirely in your browser — nothing you enter is sent or stored.
How SDE is calculated
SDE is the standard yardstick for valuing owner-operated small businesses. The formula is plain math:
SDE = Net Profit + Owner’s Salary + Interest + Depreciation + Non-Recurring Expenses
In plain English: start with the bottom-line profit on your tax return and add back every dollar that does not represent the true ongoing cost of running the business. The owner’s entire compensation gets added back — that is what makes the result seller’s discretionary earnings.
SDE vs. Adjusted EBITDA
Adjusted EBITDA uses the same add-back logic with one key difference: it leaves a market-rate manager salary in the business, so Adjusted EBITDA is lower than SDE by the cost of replacing the owner. SDE is the right yardstick for an owner-operator buyer; Adjusted EBITDA is the standard for the kind of established companies BizSellDirect acquires. The calculator above computes Adjusted EBITDA — for SDE, add your full owner compensation back instead of only the excess.
What counts as an add-back
An add-back is a cost that will not carry over to a new owner. Get them right and your business looks as profitable as it really is — overreach and a buyer will discount everything.
- Interest, depreciation, and amortization
- Owner pay above a market manager's salary
- Personal auto, travel, meals, and phone
- Non-working family members on payroll
- One-time legal, consulting, or repair costs
- Charitable donations and sponsorships
- Adding back your entire owner salary
- Normal, recurring operating expenses
- Costs a buyer will keep paying (rent, payroll, software)
- "Planned" expenses that have not actually happened
- Add-backs you cannot document on a tax return
- Inflating one-time costs that recur every year
