How to Value a Business: The Method Buyers Actually Use

Why price isn't value

Every week an owner tells us their business is "worth" a number that traces back to something other than the market: a competitor's rumored sale price, a retirement goal, or an online calculator that asked four questions. None of those things determine what a buyer will pay. In the real market for small and mid-sized businesses, value comes down to one question: how much dependable, provable cash flow does this business generate for its owner, and how risky is that cash flow? Everything else — the recipes, the reputation, the years of sweat — matters only to the extent that it shows up in, or protects, that cash flow.

The good news is that the method professional buyers, lenders and brokers use is not secret. You can apply it to your own business this afternoon. Here is how it works.

Start with seller's discretionary earnings

For owner-operated businesses — the vast majority of what changes hands in New York — the standard earnings measure is seller's discretionary earnings (SDE). SDE answers a simple question: if a single full-time owner-operator ran this business, how much total economic benefit would they receive in a year?

You calculate it from the tax return or profit-and-loss statement, starting with pre-tax net income and adding back: one owner's salary and payroll taxes, owner benefits (health insurance, retirement contributions, the car the business pays for), interest expense, depreciation and amortization, and genuinely one-time expenses. For larger companies with a management team that stays after the sale, buyers use adjusted EBITDA instead — the same idea, but without adding back a manager-level salary, because the buyer will still have to pay someone to run the place.

This is why two businesses with identical revenue can have wildly different values. A $2M-revenue restaurant netting $150K of SDE and a $2M-revenue restaurant netting $450K are entirely different assets.

Add-backs, done honestly

Add-backs are where valuations are won and lost — and where credibility dies. Legitimate add-backs include the owner's compensation, family members on payroll who don't actually work, one-time legal settlements, a flood repair, or COVID-era anomalies that are clearly behind you. Illegitimate add-backs include "the marketing we could stop doing," half the utility bill, and unreported cash revenue that appears nowhere on a tax return.

A rule we give every seller: if you cannot document an add-back with a ledger entry, an invoice or a tax form, it does not exist. Buyers' accountants will strike it, lenders will ignore it, and the attempt costs you trust on the add-backs that were real.

Cash revenue deserves a special word, because in New York's restaurant and retail world the question always comes up. The honest answer: buyers pay for what is provable. Income that never touched your books cannot be financed by an SBA lender and will not be paid for by a sophisticated buyer. The best time to fix this is two to three tax years before you sell.

Choosing the multiple

Once you have a defensible SDE figure, value is a multiplication problem: SDE × market multiple = enterprise value (usually including furniture, fixtures, equipment and a normal level of inventory, but excluding real estate and cash).

Where does the multiple come from? Comparable closed transactions, lender appetite and buyer demand. Public guides can explain the mechanics, but they cannot replace a current comp set for your industry, size and geography. As a rough orientation, owner-operated businesses are often discussed in SDE multiples, while larger firms with a real management layer are usually discussed on adjusted EBITDA. The crossover is not just revenue; it is whether the buyer must replace the owner's job after closing.

That distinction matters in New York because rent, labor, licensing and transferability can change the same earnings stream into a very different risk profile. A profitable restaurant with twenty months left on its lease is not valued like the same restaurant with two five-year renewal options. A contractor whose permits, estimator and foreman stay after closing is not valued like one where every relationship sits in the seller's phone.

What moves your multiple up or down

Buyers pay premiums for durability and discounts for fragility. The factors that consistently move the number:

• Owner dependence. If the business is you — your license, your relationships, your sixty-hour weeks — the multiple drops. Documented systems and a capable second layer of staff raise it.
• Customer concentration. One client above 20–25% of revenue frightens every buyer and most lenders.
• Revenue quality. Contracts and subscriptions beat repeat customers; repeat customers beat walk-in trade.
• The lease. In New York this can dominate everything. A below-market lease with eight-plus years of term is a genuine asset; twenty months left with no renewal option can make a business nearly unsellable.
• Books and records. Clean, consistent financials that match the tax returns don't just support the price — they speed up diligence, and speed protects deals.
• Trend. Three years of gentle growth beats a spike-and-slump pattern, even at the same average.

A worked example

Take a Queens plumbing contractor. The tax return shows $180K net income. Add back the owner's $110K salary, $14K of payroll taxes on it, $22K of health and retirement benefits, $9K of interest, $38K of depreciation and a documented $12K one-time lawsuit settlement: SDE = $385K. The company has 60% recurring maintenance-contract revenue, four licensed plumbers, mild customer concentration and a solid shop lease. Comparable service businesses closed between 2.6× and 3.2×. A supportable range is therefore roughly $1.0M to $1.23M, plus inventory at cost. Where in that range the deal lands depends on terms — all-cash offers price lower; deals with seller financing price higher.

Common mistakes that cost owners real money

After hundreds of engagements, the same errors recur: valuing revenue instead of earnings; anchoring to a friend's rumored sale price ("he got 5×!" — he didn't, or it was EBITDA on a much bigger company); pricing high "to leave room to negotiate," which mostly buys you months of silence while the listing goes stale; ignoring the lease until a buyer is at the table; and waiting for a health scare to start the process, which forces a sale into the worst possible timeline.

It is educational, not an appraisal, tax opinion or lending commitment. Add-backs, buyer treatment and tax consequences should be reconciled with qualified accounting, legal and lending professionals before a sale process.

FAQ

Should I value revenue or profit?

For most owner-operated Main Street businesses, buyers start with provable owner benefit, not revenue. Revenue helps explain scale, but the price usually depends on normalized earnings, durability and risk.

What is the fastest way to improve a valuation before selling?

Clean up documentation first: tax returns, monthly P&Ls, add-back support, leases, contracts, equipment lists and customer concentration. The same cash flow gets more buyer confidence when it is easier to verify.

The next step

You can build a serious first estimate yourself with the framework above: recast three years of financials, compute SDE, grade your risk factors honestly, and apply a conservative sector multiple. But the market has the final vote. A broker who is actively reviewing transactions in your sector can tell you where lender appetite, buyer demand and deal terms are moving now. That is what our valuation practice is built to provide: a written, defensible number and the honest list of what would need to improve before going to market.
