How Much Is a Business Worth? A Step-by-Step Guide

By Tucker Pool, M.S.I.S., Senior Valuation Analyst · Captyx

How much is a business worth? For most privately held companies, the answer is normalized earnings multiplied by a market multiple, adjusted for the assets and debt that transfer with the sale. The earnings figure is usually seller’s discretionary earnings (SDE) for smaller owner-operated businesses or EBITDA for larger ones. The multiple reflects the company’s size, industry, growth and risk. In the end, a business is worth what a qualified buyer will pay and the seller will accept, so the goal is a defensible range you can negotiate from.

The six steps below walk you through that process the way buyers and M&A advisors do it. If you’d rather start with a professional estimate, request a free business valuation.

Step 1: Gather Three Years of Clean Financials

What to do: Pull profit and loss statements, balance sheets and tax returns for the last three full years, plus year-to-date results. Reconcile the books to the tax returns and note any differences.

Why it matters: Every valuation method starts with earnings, and buyers will test your numbers against tax returns and bank statements in due diligence. Trends matter as much as totals: three years shows whether earnings are growing, stable or declining.

Common mistake: Valuing the business on a single strong year, or on internal reports that don’t tie to what was filed. See financial statements for selling and financial records cleanup tips.

Step 2: Normalize Earnings With Add-Backs

What to do: Adjust reported profit to show what the business earns under normal ownership. Add back the owner’s personal expenses run through the company, one-time costs (a lawsuit settlement, a one-off repair), and non-cash items. Adjust owner compensation to market rate, and rent to market rate if you own the building.

Why it matters: Buyers pay for the earnings they will actually receive. Legitimate add-backs can raise value meaningfully, because every dollar of added-back profit is multiplied.

Common mistake: Aggressive add-backs a buyer won’t accept. Every adjustment needs documentation. Read our guides to add-backs and normalizing earnings.

Step 3: Choose the Right Earnings Measure: SDE or EBITDA

What to do: Decide whether buyers will look at SDE or EBITDA.

  • Seller’s discretionary earnings (SDE) is pre-tax profit plus one owner’s full compensation, interest, depreciation, amortization and add-backs. It fits smaller businesses where the buyer will likely run the company.
  • EBITDA is earnings before interest, taxes, depreciation and amortization, after paying a market-rate manager. It fits larger companies with a management team, where the buyer is often a private equity group or strategic acquirer.

Why it matters: SDE and EBITDA multiples are not interchangeable. An SDE multiple applied to EBITDA, or the other way around, produces the wrong answer.

Common mistake: Comparing your business to a “multiple” you heard about without knowing which earnings figure it applied to. Learn more about seller’s discretionary earnings.

Step 4: Apply a Market Multiple

What to do: Multiply normalized earnings by a multiple drawn from comparable transactions in your industry and size range. Then adjust within that range for your company’s specific strengths and risks.

Why it matters: The multiple is where most of the negotiation happens. Factors that typically push a multiple up include:

  • Larger, growing earnings
  • Recurring or contracted revenue
  • A diverse customer base with no single customer dominating
  • A management team that can run the business without the owner
  • Documented processes and clean financial records
  • An industry where buyers are actively consolidating

Factors that typically push it down include owner dependence, customer concentration, declining revenue, heavy capital needs and pending legal or regulatory issues.

Common mistake: Using a public-company multiple or a headline figure from a much larger deal. Private companies, especially smaller ones, usually trade at lower multiples than large or public companies. See our EBITDA multiples by industry reference and what drives small business multiples.

Step 5: Cross-Check With Other Valuation Methods

What to do: Test the multiple-based result against at least one other approach:

ApproachHow it worksBest used for
Market (comparable transactions)Applies multiples from sales of similar private companiesMost profitable small and mid-sized businesses
Income (discounted cash flow or capitalization)Values the future cash flows the business is expected to generate, discounted for riskCompanies with predictable cash flows or strong growth plans
Asset-basedFair value of assets minus liabilitiesAsset-heavy, unprofitable or liquidating businesses; sets a floor on value

Why it matters: If the methods disagree sharply, something is off: earnings, the multiple or the asset values. A credible range is one that holds up from more than one angle.

Common mistake: Treating an online calculator result as the answer. Calculators are useful for a quick starting range, but they can’t see your add-backs, customer mix or risks.

Step 6: Adjust for Deal Terms, Debt and Working Capital

What to do: Translate enterprise value into what you actually take home. Most small and mid-sized deals are priced cash-free, debt-free, with a normal level of working capital left in the business. Subtract debt you’ll pay off, account for transaction costs and taxes, and look at how much of the price is paid at closing versus through a seller note or earnout.

Why it matters: Two offers with the same headline price can produce very different net proceeds. Structure, the working capital adjustment and asset vs. stock sale treatment all change what you keep.

Common mistake: Anchoring on the headline number. Ask what is paid in cash at closing and what depends on future performance. Your tax advisor should review the structure before you sign.

Worked Example: Valuing a Service Business

Illustrative example using round, hypothetical numbers. Real multiples vary widely by industry, size and risk.

Line itemAmount
Reported pre-tax profit$400,000
+ Owner salary$150,000
+ Interest, depreciation and amortization$60,000
+ Documented one-time and personal expenses$40,000
= Seller’s discretionary earnings (SDE)$650,000
– Market-rate salary for a replacement general manager$120,000
= Adjusted EBITDA$530,000

If comparable sales for businesses of this size and type supported an SDE multiple range of 2.5x to 3.5x, the indicated value would be roughly $1.6 million to $2.3 million. A buyer looking at adjusted EBITDA would apply a different multiple to the $530,000 figure, so the two methods should land in a similar range. Where the final number falls inside that range depends on the strengths and risks from Step 4, and on how many qualified buyers compete for the deal.

How Long Does a Business Valuation Take?

A quick online estimate takes minutes. A broker opinion of value or advisor-prepared valuation for a sale usually takes a few weeks once financials are in hand, because add-backs need to be documented and comparable data reviewed. A formal certified valuation for tax, estate or litigation purposes can take longer. See broker opinion of value and what a business valuation report includes.

Documents You’ll Need

  • Profit and loss statements for the last three years plus year-to-date
  • Balance sheets for the same periods
  • Business tax returns for the last three years
  • A list of add-backs with supporting receipts or invoices
  • Revenue by customer, to show concentration
  • Accounts receivable and payable aging reports
  • Fixed asset and equipment list with estimated condition
  • Debt schedule, leases and key contracts
  • Organization chart and owner’s role description

Frequently Asked Questions

How much is a business worth with $1 million in sales?

Revenue alone doesn’t determine value. Two businesses with $1 million in sales can be worth very different amounts depending on profit. A company keeping $300,000 as owner earnings is worth far more than one keeping $50,000. Buyers value earnings first, then adjust for growth, risk and industry. Start by calculating SDE or EBITDA, then apply a multiple from comparable transactions.

What is a valuation multiple?

A valuation multiple is the ratio of a company’s price to a measure of its earnings, such as SDE or EBITDA. If a business with $500,000 of EBITDA sells for $2.5 million, it sold for 5x EBITDA. Multiples vary by industry, company size, growth, customer concentration and owner dependence, which is why comparable transactions matter.

What is the difference between revenue and valuation?

Revenue is the money a business brings in from sales. Valuation is what the whole business is worth to a buyer. Valuation depends mainly on the profit that revenue produces, how reliable that profit is, and how much risk a buyer takes on. High revenue with thin margins can produce a lower valuation than modest revenue with strong margins.

Is a free online business valuation accurate?

A free online valuation is a useful starting point, giving you a ballpark range in minutes. It can’t fully reflect add-backs, customer concentration, owner dependence or industry conditions, so its accuracy depends on the inputs. Before you list or negotiate, have an experienced advisor review your actual financial statements and build a defensible range.

Does owning real estate change what my business is worth?

Usually the business and the real estate are valued separately. The business is valued on its earnings after paying market-rate rent, and the property is valued as real estate. You can sell both to the same buyer, sell the business and lease the property to the buyer, or keep the property as an investment.
