Most small businesses are worth a multiple of the cash profit they produce for an owner, adjusted up or down for risk. Start by restating your earnings to show what a new owner would really take home, then apply a multiple that reflects how dependable those earnings are. Hard assets set a floor. What a buyer can finance and still earn a living usually sets the ceiling.
This guide is for owners thinking about selling in the next few years, bringing in a partner, or simply wanting to know what they've built. You'll learn the main valuation methods, how to calculate adjusted earnings, what moves the multiple, and what you can do now to increase value. It's general education, so for an actual sale, work with a qualified business appraiser or broker, a CPA and an attorney.
The three ways small businesses are valued
| Method | How it works | Best suited to |
|---|---|---|
| Earnings multiple | Adjusted annual earnings × a multiple | Most profitable, owner-operated businesses |
| Asset-based | Fair market value of equipment, vehicles, inventory and other assets, minus liabilities | Asset-heavy businesses, or ones with little profit |
| Discounted cash flow | Projected future cash flows, discounted back to today | Larger or fast-growing businesses with reliable forecasts |
For most small businesses, the earnings multiple is the method buyers, lenders and brokers actually use. The asset value acts as a floor, since a business is rarely worth less than its assets could be sold for.
How to calculate adjusted earnings
Your tax return is designed to show as little profit as legally possible. A buyer wants to know how much cash the business really throws off. You bridge that gap with add-backs, meaning expenses that won't continue under a new owner or don't reflect normal operations.
Small businesses usually use one of two earnings measures:
- Seller's discretionary earnings (SDE): net profit plus the owner's salary and perks, interest, depreciation, amortization and one-time expenses. It shows the total benefit to one full-time owner-operator. It's common for smaller businesses.
- Adjusted EBITDA: earnings before interest, taxes, depreciation and amortization, with a market-rate salary for a manager subtracted. It's common for larger businesses where the buyer won't run things day to day. Our explainer on what EBITDA measures covers why it isn't the same as cash.
Legitimate add-backs usually include owner pay, personal expenses run through the business, one-time legal or repair costs, depreciation and interest. Add-backs a buyer will challenge include "we could cut this cost" and "that bad year was a fluke." Every add-back needs documentation.
Worked example: a hypothetical pest control company
Suppose a hypothetical pest control company with three technicians has $850,000 in annual revenue. About 70% comes from recurring quarterly service contracts. The owner handles sales and scheduling.
Step 1: Calculate SDE
- Net profit on the tax return: $62,000
- + Owner's salary: $70,000
- + Owner's personal vehicle and phone paid by the business: $9,000
- + Depreciation: $28,000
- + Interest on an equipment loan: $7,000
- + One-time legal fee from a lease dispute: $6,000
- SDE = $182,000
Step 2: Convert to adjusted EBITDA
If the buyer would hire a general manager instead of running it personally, subtract a market salary. Assume $65,000 for this role: $182,000 − $65,000 = $117,000.
Step 3: Apply illustrative multiples
Multiples vary widely by industry, size, location and market conditions. These are purely hypothetical to show the arithmetic:
- SDE at 2.5× = $455,000. SDE at 3.0× = $546,000.
- Adjusted EBITDA at 4.0× = $468,000.
The two methods land in a similar range, which is a useful cross-check. Call it roughly $450,000 to $550,000 before looking at risk factors.
Step 4: Test it from the buyer's side
Most small business purchases are financed. Suppose a buyer pays $500,000 with 10% down, borrowing $450,000 over 10 years at 10% interest. The monthly payment works out to about $5,947, or about $71,360 a year.
SDE of $182,000 minus $71,360 of debt service leaves about $110,640 for the buyer's own pay, taxes and reinvestment. That's workable. At a $700,000 price with the same terms, the buyer would borrow $630,000, debt service would rise to about $99,900, and only about $82,100 would be left. Many buyers would walk away. This affordability test is often what caps the price, whatever multiple the seller has in mind.
Step 5: Check the floor
If the trucks, equipment and chemical inventory could be sold for about $160,000, that's the rough floor. The rest of the value comes from the customer contracts, reputation and systems, often called goodwill.
What raises or lowers your multiple
Two businesses with the same earnings can sell for very different prices. Use this as a self-scoring sheet. Every item in the right-hand column is something a buyer will discount for.
| Factor | Raises value | Lowers value |
|---|---|---|
| Revenue quality | Recurring contracts, subscriptions, repeat customers | One-off projects, lumpy sales |
| Customer concentration | No customer above a small share of sales | One or two customers drive a large share |
| Owner dependence | Team handles sales, operations and key relationships | Customers and staff rely on the owner personally |
| Records | Clean, reconciled books that match tax returns | Cash sales off the books, mixed personal spending |
| Trend | Steady or rising earnings over three years | Declining or erratic earnings |
| Systems | Documented procedures, software, trained staff | Everything lives in the owner's head |
| Assets and lease | Well-maintained equipment, transferable lease | Deferred maintenance, short or non-assignable lease |
How to increase what your business is worth
Value-building takes years, not weeks. That's why exit planning is worth starting early. A practical sequence:
- Clean up the books. Reconcile every account monthly, stop running personal expenses through the business, and make sure your books tie to your tax returns.
- Document add-backs as they happen. Keep a running file of one-time costs with invoices, so you aren't reconstructing them years later.
- Shift toward recurring revenue. Service agreements, memberships and maintenance plans are worth more than equivalent one-time sales.
- Reduce concentration. If one customer is a large share of revenue, deliberately grow others.
- Make yourself less essential. Train someone to handle sales and key relationships, and write down how things are done. Our guide to succession planning covers this.
- Fix deferred maintenance and secure a lease that can transfer to a buyer.
- Get a professional valuation two to three years before you plan to sell, so you have time to act on what it finds.
Common mistakes
- Valuing on revenue alone. "Businesses like mine sell for one times revenue" ignores profit. Two businesses with the same revenue can have very different earnings, and buyers pay for earnings.
- Stretching add-backs. Every questionable add-back makes a buyer doubt the rest. Keep them documented and defensible.
- Forgetting the owner's replacement cost. If you work 60 hours a week, a buyer has to pay someone to do that. Your SDE isn't all profit to them.
- Ignoring financing. A price a buyer can't finance isn't a real price. Run the debt-service test yourself.
- Anchoring on what you need. What you need for retirement has no bearing on what a buyer will pay. Plan around realistic value, not the number you hope for.
- Waiting until you're burned out. Declining effort shows up in declining earnings, which lowers value right when you want to sell.
Where AI can help
AI tools can help with the preparation work. Export three years of profit and loss statements and a general ledger, remove customer and bank details, and ask an AI assistant to flag likely add-backs, such as one-time vendors, unusual spikes and personal-looking expenses, for you and your CPA to review. It can also build a simple model showing value and buyer debt service under different multiples, interest rates and down payments.
It can't tell you what multiple your business will command. That depends on current deal activity in your industry and region, which a qualified appraiser or broker tracks. Treat its output as preparation, not a valuation.
Frequently asked questions
What's the difference between SDE and EBITDA?
SDE includes the owner's full salary and perks, assuming the buyer will work in the business. EBITDA subtracts a market-rate manager's salary, assuming the buyer won't. SDE is usually used for smaller owner-operated businesses, and EBITDA for larger ones.
Is my business worth what I've invested in it?
Not necessarily. Buyers pay for future earnings, not past spending. A business that absorbed a lot of investment but produces modest profit may be worth less than what went into it.
How long does it take to increase business value?
Meaningful changes, such as more recurring revenue, reduced owner dependence and clean books, usually take two to three years to show up in the numbers a buyer will review.
Should I buy an existing business at these multiples instead of starting one?
It depends on your capital, skills and appetite for risk. We compare the trade-offs in buying an existing business versus starting from scratch.
Key takeaways
- Most small businesses are valued as a multiple of adjusted earnings, either SDE or adjusted EBITDA.
- Add-backs turn tax-return profit into real owner benefit, but each one must be documented.
- Risk sets the multiple: recurring revenue, low concentration and low owner dependence raise it.
- Test the price from a buyer's side. It has to support loan payments and a living wage.
- Asset value sets a floor, and goodwill sits on top of it.
- Start building value two to three years before you want to sell, with professional help.
