How to Value a Small Business: The Methods Buyers Actually Use

How to value a small business with an SDE multiple

Seller’s discretionary earnings is the total financial benefit one full-time owner-operator takes from the business. It is the usual starting point for smaller, owner-led companies. A buyer starts with reported earnings. Then the buyer adds back costs that are documented and won’t continue under new ownership. This process is called a recast, or normalizing the financials.

Common add-backs include:

• Owner compensation: the salary and benefits paid to one working owner.
• Personal expenses: costs the company paid that served the owner personally, such as a personal vehicle or a family phone plan.
• One-time costs: unusual expenses that won’t repeat, such as legal fees from a settled dispute.

Every add-back needs proof. Expect a buyer to check invoices, payroll records, and tax returns before accepting one. If a cost will continue after the sale, it stays in the expense base. Owners who stretch their add-backs often see a buyer discount the whole recast.

A worked SDE example

Suppose a company reports $100,000 in EBITDA, which stands for earnings before interest, taxes, depreciation, and amortization. The figures below are hypothetical round numbers for illustration.

Now imagine one buyer applies a multiple of 2 and another applies a multiple of 3. Their estimates land at $400,000 and $600,000. These multiples are for this example only. They do not reflect market benchmarks or real offers.

The $200,000 gap between those estimates comes from one question. How confident is each buyer that the earnings will continue after the owner leaves? The factors that drive that confidence come later in this guide.

When buyers use an EBITDA multiple or asset value

Some companies have a management team and run without the owner in a daily role. For those, buyers usually shift from SDE to an EBITDA multiple. EBITDA lets a buyer compare the profit of companies with different debt, taxes, and equipment costs.

The big change is how your pay is treated. SDE adds back one owner’s full compensation. An EBITDA buyer assumes the company must pay someone to do your job. So the buyer subtracts a market-rate salary for that role. Take a hypothetical owner who earns $250,000 in a role a general manager could fill for $150,000. A buyer would add back only the $100,000 difference. Each adjustment still needs records that show why it will disappear after a sale.

Owner dependence matters even more at this stage. A business that keeps its customers and hits its targets without the owner supports a stronger EBITDA multiple. Heavy reliance on the owner pulls the multiple down, even when recent profits look strong. This is where what strategic buyers look for in your business starts to shape the price.

The asset-based approach comes into play when earnings are weak, uneven, or tied closely to equipment, property, or inventory. A buyer estimates what the assets could realistically sell for. Then the buyer subtracts liabilities and the cost of selling. A machine shop with valuable equipment and thin profits may draw a price close to its net asset value.

Net asset value often sets a floor, though that floor can sit lower than owners expect. Used equipment often sells below its book value. Some assets are hard to sell at all. Debt and other obligations also reduce what remains for you.

How forecasts and comparable sales test the estimate

A multiple gives you a starting estimate. Buyers then test it two ways. They ask whether future cash flow supports the price. They also ask whether similar businesses have sold for it.

The income approach looks ahead. A discounted cash flow (DCF) model projects the cash the business will produce in future years. It then reduces that cash to today’s value to account for time and risk. A capitalization of earnings model is simpler. It divides one steady, expected level of earnings by a rate that reflects risk. Both methods depend heavily on the forecast. A buyer will question growth plans that need new staff or equipment without the cash to pay for them.

The market approach looks outward. It compares your business with sales of similar private companies. The usual yardstick is a price-to-SDE or price-to-EBITDA multiple. Brokers and appraisers pull these comparisons from databases of closed private deals. Good comparisons account for size, margins, customer mix, and deal terms. A headline multiple can mislead when the sale included real estate, seller financing, or an earnout.

Industry rules of thumb, such as a percentage of annual revenue for a given sector, work best as a final sanity check. They can flag an estimate that needs a second look. They can’t tell you whether your earnings will transfer to a new owner.

A credible small business valuation uses two or three of these methods. The goal is a range where the methods roughly agree.

What raises or lowers the multiple a buyer will pay

A buyer can agree with your earnings figure and still offer less than you expect. The multiple reflects how much of that income the buyer believes will survive a change in ownership. TAB facilitators see five factors come up again and again.

• Owner dependence: If you approve every quote, hold the key customer relationships, and solve each daily problem, a buyer must price in the cost and risk of replacing you. That lowers the multiple.
• Customer concentration: When one customer makes up a large share of revenue, losing that account could cut cash flow sharply. Buyers respond with a lower multiple, tougher deal terms, or both.
• Recurring revenue: Contracts, subscriptions, and repeat orders make future sales easier to predict. Buyers tend to pay more for predictable revenue, after they check renewal rates, transfer terms, and margins.
• Financial records: Clean, consistent statements let a buyer verify revenue, expenses, and add-backs quickly. Gaps or mixed personal costs raise doubt about every number in the valuation, and doubt lowers the multiple.
• Management depth: A capable team keeps sales, service, and operations steady after you leave. When every decision runs through one person, the buyer faces new payroll costs and a rough transition.

Each factor comes back to one question. How much risk comes with the cash flow? Building a more valuable, transferable company means lowering that risk year by year. That is the focus of The Alternative Board’s Business Builder’s Advantage program. The work takes time, which is why exit planning needs to begin well before you plan to exit.

How to get a credible small business valuation

TAB facilitators often see owners surprised by a buyer’s number. The gap usually comes down to evidence. A buyer needs proof of how much cash the business produces without the owner, and how much risk comes with it.

A broker’s opinion of value is a practical estimate of what buyers might pay in today’s market. Business brokers often prepare one when they take on a listing. It helps you test an asking price and spot weak points early. Its quality depends on the records and comparable sales behind it.

A formal appraisal is a documented report from a credentialed valuation professional. Look for designations such as CVA (Certified Valuation Analyst), ABV (Accredited in Business Valuation), or ASA (Accredited Senior Appraiser). A formal appraisal fits when a lender, court, tax filing, partner buyout, or ownership dispute calls for an independent value. It also matters when you plan to pass the company to family or a partner. That step is a key part of effective business succession planning. For early planning, a broker’s opinion is often enough to start.

Small business valuation FAQ

How many times profit is a small business typically worth?

There is no single multiple that fits every business. Smaller owner-run companies are usually priced on a multiple of SDE. Larger companies with a management team are usually priced on EBITDA. In either case, the multiple rises or falls with risk, including owner dependence, customer concentration, recurring revenue, and the quality of your records.

Does revenue determine a business’s value?

Revenue shows how big a business is. Buyers care more about the earnings that revenue produces and how long those earnings will last. Two companies with the same sales can draw very different offers when their margins, customer mix, or owner roles differ. That is why buyers start with SDE or EBITDA.

What is the fastest way to estimate what my business is worth?

Recast your last three years of financial statements to find SDE or EBITDA. Then apply a multiple drawn from sales of comparable businesses in your industry and size range. Treat the result as a rough range. Each add-back and each comparison still needs a close look before you rely on it.

How much does a business valuation cost?

Cost depends on the type of valuation and the work involved. A broker’s opinion of value is sometimes offered at little or no cost when it is tied to a possible listing. A formal appraisal costs more because it requires deeper analysis and a documented report. Agree on scope before you compare fees.

Should I get a valuation even if I’m not selling?

Yes. An early valuation shows which value drivers need work while you still have years to improve them. It gives you a baseline to track over time. It also helps with partner agreements and estate planning. The first number often sets the agenda for your next few years of planning.
