How to Calculate a Business Valuation in 2026 (3 Methods, Step by Step)

There are three recognized ways to value a business, income, market, and asset, and which one drives the answer depends on what kind of business you have. Most owner-operated companies are valued on the market approach: a normalized earnings number times an industry multiple. Larger, predictable businesses lean on the income approach (discounted cash flow). Asset-heavy or unprofitable businesses fall back to the asset approach. This guide walks through all three step by step, shows how to normalize earnings, and works a simple example, so you can produce a defensible range, not just a guess.

We’re CT Acquisitions, a buy-side M&A advisory firm; the ranges and multiple drivers here come from the transactions we work on and our network of 100+ active capital partners.

The short answer, and the three methods at a glance

For most owner-operated businesses, the calculation is: normalized earnings × market multiple = enterprise value, then adjust for cash, debt, and working capital to get to equity value. Here’s how the three recognized approaches compare:

How we use this: in practice a defensible valuation triangulates two or three of these, the market approach anchors it, the income approach sanity-checks it for cash-flow-rich businesses, and the asset approach sets a floor. The ranges and multiple drivers below reflect the transactions in our network of 100+ active capital partners; your actual number depends on the specifics.

Step 1: Normalize the earnings

You can’t multiply reported net income, it’s distorted by owner choices and one-time events. Normalize it:

• Add back the owner’s compensation, for SDE, add back one working owner’s entire salary and benefits; for EBITDA, add back only the amount above what a hired manager would cost.
• Add back personal expenses run through the business, personal vehicles, travel, phone, family on payroll who don’t work there, discretionary spending. Document each.
• Add back one-time / non-recurring items, a lawsuit settlement, a one-time consulting fee, costs of a move, COVID-era anomalies.
• Add back non-cash items, depreciation and amortization (the “DA” in EBITDA), plus interest and taxes for EBITDA.
• Adjust for items that should be there but aren’t, if the owner underpays themselves or family, or rent is below market in an owner-owned building, the buyer will normalize the other way.

The result is SDE (for smaller, owner-operated businesses, it represents the total benefit to a single working owner) or EBITDA (for larger businesses with a management layer in place). Keep documentation for every adjustment, undocumented add-backs get struck in diligence and the price drops with them.

Step 2 (market approach): Apply the multiple

Multiply normalized earnings by a multiple drawn from comparable transactions in your industry and size band. Broad reference points (these vary widely by sector, see our multiplier guide for detail):

Then adjust within (or beyond) the range for the factors that actually move it:

• Recurring revenue %, often the biggest swing; contracted/subscription revenue commands a premium over project/transactional.
• Customer concentration, any customer over 15-20% of revenue is a discount; over 40% can be disqualifying.
• Owner dependency, a business that runs without the owner is worth 0.5-1.5 turns more than one that doesn’t.
• Growth trajectory, 15%+ growth adds turns; decline subtracts them.
• Margins and trends, above-sector margins and stable/improving trends push the multiple up.
• Management team, a non-owner team that stays reduces transition risk and raises the price.

Step 2 (income approach): Discounted cash flow

For larger, predictable businesses, DCF: (1) project unlevered free cash flow for a forecast period (commonly 5 years); (2) pick a discount rate, the weighted average cost of capital (WACC), reflecting the risk of those cash flows; (3) discount each year’s cash flow to present value; (4) add a terminal value (the value of all cash flows beyond the forecast, via a perpetuity-growth or exit-multiple method), discounted back; (5) sum it, that’s enterprise value. DCF is sensitive to the discount rate and terminal assumptions, so it’s typically used to sanity-check a market-approach value rather than stand alone for a small business.

Step 2 (asset approach): Adjusted net asset value

Restate the balance sheet to fair market value, real estate and equipment to appraised value, inventory to realizable value, receivables net of bad debt, then subtract all liabilities. For an operating business this is usually a floor (it ignores goodwill and earning power); it becomes the primary method for holding companies, asset-heavy businesses, or businesses that don’t generate meaningful profit.

Step 3: Bridge from enterprise value to what you’ll actually receive

The multiple gives you enterprise value (the value of the operating business). To get to equity value (what goes to the owner): add cash, subtract interest-bearing debt, and adjust for working capital relative to a normal target. Then consider deal structure, cash at close vs. seller note vs. earnout vs. rollover equity, all of which affect the timing and certainty of what you net. And remember taxes: an asset sale and a stock sale can produce materially different after-tax proceeds from the same headline price.

Worked example (market approach)

A commercial services business: reported net income $180K. Add back owner’s salary $150K, owner’s personal vehicle and travel $25K, a one-time legal settlement $20K, and D&A $35K, normalized SDE ≈ $410K. The business is owner-operated with ~55% recurring contract revenue, no customer over 12%, modest growth, and a capable lead technician who’ll stay. Sector SDE multiples run ~2.5x-4.5x; the recurring revenue, low concentration, and key-employee stability push toward the upper-middle, say ~3.75x. Enterprise value ≈ $410K × 3.75 ≈ $1.54M. With minimal debt and normal working capital, equity value lands near that, before structure and taxes. Cross-checked against a DCF and an asset floor, the defensible range might be roughly $1.4M-$1.7M.

How we know this: the ranges, timelines, and dynamics on this page come from the transactions we’ve worked on and the buyer mandates in our network of 100+ active capital partners. They’re informed starting points, not guarantees, your actual outcome depends on the specifics of your business and your situation.

How to get a number you can defend

Do all three approaches, lead with the market approach, sanity-check with DCF if the cash flows support it, set a floor with the asset approach, and reconcile to a range. Document every earnings normalization. Then either get a professional valuation (a credentialed appraiser, ASA/ABV/CVA, for litigation, estate, or contested situations) or, for a market check, use our free 90-second tool, which applies sector-specific multiples and risk adjustments. For more depth, see our valuation resources, multiplier guide, valuation template, and sample valuation report. When you’re ready to test the number against real buyers, that’s a sell-side process, and with the buyer-paid model you pay no advisory fee; see our broker alternative guide.

Frequently asked questions

How do you calculate the value of a business?

For most owner-operated businesses: take normalized earnings, Seller’s Discretionary Earnings (SDE) for smaller owner-run businesses or EBITDA for larger ones with a management team, and multiply by a market multiple for your industry and size, then adjust for cash, debt, and working capital to reach equity value. Normalize earnings by adding back the owner’s above-market compensation, personal expenses run through the business, one-time items, and non-cash charges. Larger, predictable businesses also use a discounted cash flow (income approach); asset-heavy or unprofitable ones use adjusted net asset value (asset approach). A defensible valuation triangulates two or three of these.

What is the formula for valuing a small business?

The most common formula is: normalized SDE × an SDE multiple (typically around 2x-4.5x depending on sector, size, recurring revenue, customer concentration, owner dependency, and growth). ‘Normalized SDE’ = reported pre-tax profit + the owner’s salary and benefits + personal expenses run through the business + one-time items + depreciation and amortization. Larger businesses use normalized EBITDA × an EBITDA multiple (typically ~4x-10x+) instead. The multiple is the variable, it moves with the risk and quality of the business.

What is the difference between SDE and EBITDA?

SDE (Seller’s Discretionary Earnings) adds back one working owner’s entire compensation and benefits plus personal expenses, it represents the total financial benefit to a single owner-operator, and is used to value smaller, owner-run businesses. EBITDA (earnings before interest, taxes, depreciation, and amortization) adds back only owner compensation above what a hired manager would cost, it assumes professional management is in place, and is used for larger businesses. For the same business, SDE is a bigger number than EBITDA, so SDE multiples are lower than EBITDA multiples; they’re not interchangeable.

How do you calculate a business valuation multiple?

You don’t calculate the multiple from a formula, you derive it from comparable transactions: what businesses similar to yours in industry, size, and profile actually sold for, expressed as a multiple of their SDE or EBITDA. Then you adjust within that range for your business’s specifics: recurring revenue percentage, customer concentration, owner dependency, growth rate, margin trends, and management-team strength. Industry databases, broker reports, and advisory networks supply the comparable multiples; the adjustment is judgment grounded in the risk and quality of the business.

What is a discounted cash flow valuation?

DCF estimates a business’s value as the present value of its future cash flows. You project unlevered free cash flow over a forecast period (commonly 5 years), choose a discount rate (the weighted average cost of capital, reflecting the risk of those cash flows), discount each year’s cash flow back to today, add a terminal value for all cash flows beyond the forecast (also discounted), and sum it, that’s enterprise value. DCF is most useful for larger businesses with predictable cash flows and a credible forecast; for small businesses it’s typically used to sanity-check a market-approach value rather than stand alone.

Should I hire a professional business appraiser?

For litigation, divorce, estate and gift tax, ESOP, partner buyouts, or any contested or regulatory situation, yes, you need a credentialed appraiser (ASA, ABV, or CVA) producing a formal report that will stand up to scrutiny. For a market check before talking to buyers, a sector-adjusted estimate from a tool like ours, or an indicative valuation from a sell-side advisor, is usually enough to set expectations and start a process. Many owners do the informal version first and commission a formal appraisal only if and when the situation requires it.

Why do two valuations of the same business differ?

Because valuation is a range, not a point, and it depends on the purpose, the method, and the assumptions. A fair-market-value appraisal for tax purposes (which often applies discounts for lack of control and marketability) can differ materially from a strategic buyer’s view (which may price in synergies). The earnings normalization, the multiple chosen, the discount rate in a DCF, and the deal structure all move the number. A credible valuation explains its assumptions and presents a defensible range; be wary of any single number presented without that context.

How does deal structure affect what I actually get from my business valuation?

Significantly. The valuation gives you enterprise value, then you adjust for cash and debt to get equity value, then deal structure determines what you actually receive and when: cash at close is certain; a seller note is paid over years with default risk; an earnout is contingent on future performance; rollover equity is a bet on the buyer’s success. And taxes matter, an asset sale and a stock sale can produce very different after-tax proceeds from the same headline price. The headline valuation is the starting point, not the take-home number; model the after-tax, risk-adjusted proceeds before agreeing to a structure.
