What Is SDE? Seller's Discretionary Earnings, Explained in Plain English

SDE — seller's discretionary earnings — is the total financial benefit a single working owner pulls out of a business in a year: the net profit on the books, plus the owner's own salary, plus the perks and paper expenses that wouldn't apply to a new owner. It exists because small-business tax returns are written to minimize taxes, not to impress buyers — so the industry recasts them. SDE is the number Main Street businesses are actually priced on, at a multiple that currently averages 2.7×. Get SDE right and the price conversation is arithmetic. Get it wrong and everything built on it wobbles.

The formula, and what legitimately adds back

Start with net profit per the P&L. Add back: the owner's salary and its payroll taxes, owner health insurance, the personal vehicle, discretionary travel that was really vacation, interest (the buyer brings their own financing), depreciation and amortization (paper, not cash), and genuine one-time items — the lawsuit that settled, the POS system bought once. The test for a defensible add-back: it benefited the owner rather than the business, the business paid it, and it's visible on the tax return and P&L. If an add-back fails that test, a buyer's accountant will fail it for you later.

What doesn't add back, despite regular attempts: expenses the new owner still faces (rent, real staff, software the business runs on), "one-time" costs that somehow recur every year, and — the subtle one — free family labor. If your spouse runs the books unpaid, a buyer must hire a bookkeeper, which reduces SDE rather than padding it.

The multiple depends on size — meet the ladder

Buyers pay more per dollar of earnings as businesses get bigger, because bigger businesses depend less on one heroic owner. The IBBA's Market Pulse data makes it a ladder:

SDE vs. EBITDA: same business, two numbers

SDE assumes the buyer works in the business, so the owner's pay adds back. EBITDA assumes hired management, so a market-rate manager's salary stays in as a cost. Maria's café: $185,000 SDE, minus a $75,000 manager and payroll costs ≈ $108,000 adjusted EBITDA. Neither number is wrong; they answer different questions — "what does an owner-operator earn?" versus "what does this asset yield with staff running it?" The handoff happens around $1–2 million of earnings, which is why our EBITDA multiples guide reads like a different planet from this page: it is — the planet where buyers hire managers.

Where SDE fights break out — and how to win yours

Salary, depreciation, and interest rarely get argued. The fights cluster around non-recurring claims ("one-time" marketing that happens annually), personal expenses with no paper trail, and family labor. Every disputed add-back matters threefold: at 2.7×, a $10,000 add-back that dies in scrutiny takes roughly $27,000 of price with it.

And scrutiny now has teeth. SBA lenders re-underwrite earnings to a 1.15 coverage floor (banks want ~1.25), and on $3M+ deals a quality of earnings review is now mandatory — an independent accountant testing exactly these add-backs. The seller's playbook is unglamorous: document every add-back with invoices, stop running personal costs through the business a year before listing (our 12-month plan schedules this), and have your broker pressure-test the recast before it goes in the book. An SDE that survives a bank is a price that survives a buyer.

Frequently asked questions

What is SDE in a business sale?

The total yearly financial benefit to one working owner: net profit plus owner salary and payroll taxes, perks, interest, depreciation, and documented one-time items. Main Street deals price at a multiple of it — currently averaging 2.7×.

What's the difference between SDE and EBITDA?

SDE adds the owner's salary back (buyer works the business); EBITDA keeps a manager's salary in (buyer hires one). The same café can show $185K SDE and ~$108K adjusted EBITDA. The handoff comes around $1–2M of earnings.

What add-backs are allowed?

Ones that benefited the owner, were paid by the business, and show on the returns and P&L. Not allowed: costs the new owner inherits, recurring "one-time" items, and unpaid family labor the buyer must replace.
