To value a small business before you buy, start with what it actually earns, adjust those earnings for the owner’s personal expenses and one-time items, then compare the result with similar sales and the value of the assets. There is no single correct price. A valuation is a reasoned estimate built from verified numbers, and it is only as good as the records behind it. This guide explains the most common methods used for small businesses, with a worked example, so you can ask smarter questions when a seller names a price.
Why valuation matters
Overpaying is one of the most expensive mistakes a buyer can make, because the purchase price sets your debt, your payments, and how long it takes to recover your investment. Underpaying is not the goal either, since a fair offer helps you close a deal with a motivated seller. Valuation gives you a basis for negotiation, and it supports your lender’s analysis. Pair it with the checks in how to buy an existing business: due diligence.
Start with the right earnings number
The profit on a tax return rarely tells the full story for a small business, since owners run personal costs through the company and take their pay in different forms. Brokers and buyers commonly use seller’s discretionary earnings (SDE). It is generally calculated as:
- Net profit before taxes
- plus the owner’s salary and benefits
- plus interest, depreciation, and amortization
- plus one-time or non-recurring expenses
- plus personal expenses the owner ran through the business
Each of these additions is called an add-back. For larger businesses with a manager in place, buyers often use EBITDA instead, which does not add back an owner’s full compensation.
A hypothetical example
Suppose a cleaning company reports net profit of $60,000. The owner paid themselves $50,000, the company expensed $6,000 of vehicle costs that were mostly personal, and a one-time legal fee of $4,000 appears this year. Depreciation is $5,000. SDE would be $60,000 + $50,000 + $6,000 + $4,000 + $5,000 = $125,000. This is only an illustration; real numbers must come from records you verify.
Be skeptical of add-backs
Add-backs are where valuation disputes happen. A seller may claim many items, and some are legitimate while others are not. Ask for documentation and use judgment:
- Legitimate: a documented one-time lawsuit settlement, an owner’s personal car payment, or a family member’s pay for no work.
- Questionable: repairs the business will need again, marketing the seller skipped this year, or an “owner’s salary” that is far below what a replacement manager would cost.
- Unsupported: cash income that does not appear in the tax returns or bank deposits. Do not pay for revenue you cannot verify.
Apply a multiple
Once you have a verified earnings number, you commonly apply a multiple to estimate value. Multiples are not fixed. They vary by industry, size, growth, customer concentration, and how dependent the business is on the owner. A small, owner-operated company usually sells for a lower multiple of earnings than a larger, stable business with a management team. Stronger recurring revenue and diversified customers tend to support higher multiples, while heavy owner dependence, declining sales, or a short lease can lower them.
Ask a broker or valuation professional for recent comparable sales in your industry and size range, and treat any rule of thumb as a starting point rather than an answer. In the example above, a multiple of two to three times SDE would imply a very different price range than one to one-and-a-half times, which is why the justification matters more than the number.
Three common valuation approaches
| Approach | How it works | Best for |
|---|---|---|
| Earnings multiple | Verified SDE or EBITDA times a market multiple | Most operating small businesses |
| Asset-based | Value of equipment, inventory, and other assets minus liabilities | Asset-heavy or struggling businesses |
| Market comparison | Prices of similar businesses that recently sold | Cross-checking an earnings multiple |
Many valuations blend methods. If the asset value is higher than the earnings-based price, the business may be worth more to a buyer who liquidates it. If the earnings-based price is much higher than the assets, you are paying for goodwill, such as the customer base and reputation, which makes transition planning important.
Adjust for risk
- Owner dependence: can customers and employees stay after the owner leaves?
- Customer concentration: does one customer account for a large share of revenue?
- Trends: are sales and profit rising, flat, or falling?
- Lease and licenses: do they transfer, and for how long?
- Industry changes: technology and regulations can reshape demand. See AI business opportunities for small business for one example.
- Franchise obligations: if the business is a franchise, transfer fees and remaining term matter. See buying an existing franchise location.
Check what is included in the price
Clarify whether the price includes inventory, equipment, vehicles, accounts receivable, the lease, the business name, the website, and customer lists. Decide how working capital will be handled. A price that looks low can be expensive if you must immediately fund inventory or replace aging equipment. Put each item into the purchase agreement.
Test the price against your financing
Run a simple affordability check. After paying loan payments, a manager’s salary if you will hire one, and a reasonable income for yourself, does the business still generate a cushion? Lenders often look at debt service coverage, which compares cash flow with required loan payments. See how to finance a business opportunity for how SBA and other options work.
Get professional help
Hire an accountant who has reviewed small-business sales and an attorney to review the agreement. For larger deals, a formal valuation or quality-of-earnings review may be worth the expense. A broker can also provide comparable sales data, as described in working with a business broker.
Frequently asked questions
What multiple should I pay for a small business?
There is no universal multiple. It depends on the industry, the size, the stability of earnings, and how dependent the business is on the owner. Use comparable sales and a professional’s input rather than a rule of thumb.
What is the difference between SDE and EBITDA?
SDE adds back the owner’s full compensation and is commonly used for owner-operated businesses. EBITDA does not add back the full owner salary and is more common for larger businesses with management in place.
Should I pay for goodwill?
Goodwill is often a large part of a small business’s price, but it only has value if customers and revenue will continue after the sale. A transition period and non-compete agreement help protect it.
Can I rely on the seller’s valuation?
Treat it as the seller’s opening position. Verify earnings and compare with market data before you negotiate.
Turning a valuation into an offer
Once you have a supported value range, structure your offer rather than just naming a number. Price is only one lever. Terms often decide whether a deal works for both sides:
- Seller financing: the seller accepts part of the price over time, which can show confidence in the business and reduce the cash you need at closing.
- Earn-outs: part of the price depends on future performance, which can bridge a gap when you and the seller disagree about growth.
- Working capital and inventory: agree on a normal level so you do not buy a business that is already starved of cash or stock.
- Transition period: a defined training and introduction period from the seller, with clear hours and duration.
- Non-compete: a reasonable restriction that keeps the seller from opening a competing business nearby.
- Contingencies: your obligation to close depends on financing approval, a satisfactory review of records, and landlord and franchisor consent where needed.
Ask your attorney to build these terms into a letter of intent and then the purchase agreement. If the seller will not allow you to verify the numbers, or insists on skipping steps to close quickly, be willing to walk away. The best protection a buyer has is the ability to say no.
The bottom line
A sound valuation begins with verified earnings, uses reasonable add-backs, compares multiples and assets, and adjusts for risk. Before you sign, make sure the price still works with your financing and that professionals have reviewed the numbers.
