Business Valuation Calculator

Estimate business value using SDE multiple, revenue multiple, and DCF methods.

About this calculator

This calculator estimates a small business's value three different ways from the same two core numbers -- Annual Revenue and Seller's Discretionary Earnings (SDE) -- and then averages them. The SDE Multiple Valuation multiplies SDE by the SDE Multiple you enter, the standard approach for owner-operated businesses since SDE already adds back owner salary, benefits, and other non-operating expenses a buyer wouldn't inherit. The Revenue Multiple Valuation is a simpler top-line check: Annual Revenue times the Revenue Multiple.

The DCF Valuation is more involved -- it projects SDE forward five years at your Expected Growth Rate, discounts each year's cash flow back to today at your Discount Rate, and adds a Terminal Value representing everything beyond year 5 using the Gordon growth formula. Average Valuation is a plain, unweighted average of all three methods, which means a DCF Valuation swollen by an aggressive growth rate (or a discount rate set close to it) can pull the blended figure well above what either multiple-based method alone would suggest. What this calculator does NOT do: it doesn't verify that SDE was calculated correctly, doesn't apply industry-specific risk premiums, doesn't separately account for tangible or intangible assets and liabilities, and doesn't adjust for deal structure, working capital, or how a buyer finances the purchase -- all of which matter in a real valuation negotiation.

How to Use This Calculator
  1. Enter your annual revenue and Seller's Discretionary Earnings (SDE) -- net income plus owner salary, benefits, and other add-backs a buyer would not have to pay.
  2. Set a revenue multiple and an SDE multiple appropriate for your industry (SDE multiples for small businesses typically run 2-4x).
  3. Enter a discount rate (your required rate of return) and an expected annual growth rate for the 5-year discounted cash flow (DCF) projection.
  4. Compare the SDE Multiple Valuation, Revenue Multiple Valuation, and DCF Valuation, along with the Average Valuation that blends all three.
  5. Check SDE Margin as a quick read on earnings quality, and use Terminal Value to see how much of the DCF figure comes from cash flows beyond year 5.

Frequently Asked Questions

Why does the calculator average three very different valuation numbers together?

Because no single method is authoritative for a small business sale -- Average Valuation blends the SDE Multiple, Revenue Multiple, and DCF results with equal weight. If the DCF Valuation is much higher than the other two (which happens whenever growth rate is high relative to discount rate), it will pull the average upward even though multiple-based methods are usually considered more reliable for small deals.

What exactly counts as Seller's Discretionary Earnings?

SDE is net income plus owner salary, benefits, personal expenses run through the business, and other one-time or non-operating add-backs -- essentially the total financial benefit available to a single owner-operator. It's the standard earnings figure used for small business sales, distinct from EBITDA, which doesn't add back owner compensation.

How sensitive is the DCF Valuation to the discount rate I choose?

Quite sensitive -- raising the discount rate lowers the DCF Valuation, since future cash flows and the terminal value are both discounted more heavily back to the present. Because the terminal value formula divides by the gap between discount rate and growth rate, a discount rate set close to your growth rate produces an unusually large valuation, so the two should reflect a realistic risk premium apart.

Why would the SDE Multiple Valuation and Revenue Multiple Valuation give such different answers?

They measure different things: the Revenue Multiple Valuation ignores profitability entirely and just scales top-line revenue, while the SDE Multiple Valuation is anchored to actual owner earnings. A business with high revenue but thin margins can show a much higher revenue-based valuation than its SDE-based one -- a mismatch worth investigating rather than averaging away.

Does increasing the growth rate always raise the DCF Valuation?

Yes -- a higher Expected Growth Rate increases the projected cash flow in every future year and raises the terminal value, so DCF Valuation increases as growth rate rises, holding discount rate and SDE fixed. This makes the DCF figure the most assumption-driven of the three valuation methods, since a small change in growth rate can move it substantially.
