How this instrument works
The market-multiple method prices a business the way a used-car lot prices inventory: find what similar units recently sold for, express that as a ratio to a measurable figure, then apply the ratio to the business in front of you. Here the measurable figure is annual earnings — Seller's Discretionary Earnings for an owner-run shop, EBITDA once the business is large enough to run without its founder — and the ratio is the multiple that trade data says buyers in that industry are currently paying for a dollar of that earnings stream.
A business broker pulls the multiple from closed-deal databases like the IBBA Market Pulse survey or BizBuySell's transaction records, narrowed to the same industry, revenue band, and region as the subject company. A coin laundry with thin margins and heavy equipment risk might trade at 2x SDE; a bookkeeping firm with recurring monthly retainers and low customer churn can command 4x or more, because the multiple is a stand-in for risk and durability, not just size. The same $200,000 in earnings is worth more when a buyer believes it will keep showing up next year with minimal effort.
This is a first-pass number, not an appraisal. It skips the balance sheet entirely — inventory, equipment, real estate, and outstanding debt or receivables typically get settled separately in a letter of intent — and it assumes the earnings figure has already been normalized, with one-time expenses and above-market owner perks added back. A formal valuation would also run discounted cash flow and comparable-transaction analysis and reconcile the three toward a single figure; this calculator gives you the fast one to sanity-check the other two against.
- Enter Annual earnings (SDE or EBITDA), $ — the normalized profit figure after add-backs, not the raw number from a tax return or income statement.
- Enter the Industry multiple your research supports — pulled from a broker's comparable-sale data for businesses of similar size and risk in the same trade.
- Read Estimated valuation — earnings multiplied straight through, with no balance-sheet items added or subtracted.
- Re-run the multiple at the low and high end of the range your data supports to see how wide the resulting price band really is.
- Treat the output as an opening anchor for negotiation, not a number to defend without also checking DCF or recent comparable sales.
Worked example — a $200,000-earner at 3x
A small business generates $200,000 a year in Seller's Discretionary Earnings after add-backs, and comparable sales in its trade have recently closed around a 3x multiple — typical for a stable, owner-dependent operation without much competitive moat. Valuation = 200,000 × 3 = $600,000, the figure a broker would list as the asking-price anchor before working the balance sheet into the deal structure.
Move the multiple and the anchor moves with it: the identical $200,000 earner at a 2x multiple, common for a business heavily reliant on the owner's personal relationships, prices at $400,000, while a 4x multiple for a business with a management team already in place and contracts locked in prices the same earnings at $800,000. The earnings figure barely changed the story here — the multiple did, because it is where the market prices risk and repeatability, not raw profit.
Questions
Should I use SDE or EBITDA for the earnings figure?
Use SDE for a business the owner actively runs day to day — it adds back the owner's salary and personal perks, since a new owner-operator would take that role themselves. Use EBITDA once a business has a management team drawing market-rate pay, typically past a few million in revenue, because SDE would then overstate the earnings a passive buyer actually receives.
Where does the industry multiple actually come from?
From databases of closed private-business sales — IBBA's Market Pulse survey and BizBuySell's transaction data are the two most cited — filtered to the same industry, revenue size, and geography as the subject business. Multiples for the same industry can still span a wide range depending on customer concentration, lease terms, and growth trend.
Why does a higher multiple mean the business is worth more for the same earnings?
The multiple prices how much a buyer trusts that earnings figure to repeat with minimal risk and effort. Recurring contracts, a trained staff, and diversified customers push it up; heavy owner dependence, aging equipment, or one or two customers driving most of the revenue push it down. Two businesses with identical profit can carry very different multiples.
Does this valuation include the building, equipment, or debt?
No. It prices the earnings stream alone. Real estate, inventory, and equipment are commonly negotiated as separate line items on top of or folded into the deal, and any outstanding business debt is typically settled at closing rather than baked into this multiple. Ask what basis — cash-free, debt-free — a quoted multiple assumes.
What's the most common mistake people make with this formula?
Feeding it an earnings figure that was never normalized — the raw net income off a tax return, which is usually minimized for tax purposes and understates what a buyer would actually receive. Add back the owner's salary and perks, one-time expenses, and non-cash charges first, or the multiplication starts from a number too small to mean anything.
Is a multiple-of-earnings valuation the same as a formal business appraisal?
No — it is one input a formal appraisal would triangulate alongside discounted cash flow and a comparable-transactions analysis, then reconcile into a single figure. Lenders, courts, and the IRS for gift or estate purposes typically require that fuller reconciled valuation, not a single multiple applied on its own.
