Business Valuation Formula
A mathematical method used to estimate the economic value of a business, with the most common approaches being EBITDA multiples, discounted cash flow analysis, and asset-based valuation.
What is a Business Valuation Formula?
A business valuation formula is a structured calculation used to estimate what a business is worth. No single formula works for every situation. The right approach depends on the size of the business, the industry, the buyer type, and the purpose of the valuation.
Three formulas dominate M&A transactions.
EBITDA Multiple Method
The most widely used formula in middle-market transactions:
Business Value = EBITDA x Industry Multiple
A company earning $1.5 million in adjusted EBITDA in an industry with a typical 5x multiple would be valued at approximately $7.5 million.
The multiple varies based on growth rate, revenue quality, customer concentration, competitive position, and market conditions. Multiples for small businesses typically range from 3x to 6x, while larger or high-growth companies can command 8x to 15x or more.
For smaller businesses with owner-operator involvement, SDE (Seller's Discretionary Earnings) replaces EBITDA, and multiples are generally lower, ranging from 2x to 4x.
Discounted Cash Flow (DCF) Method
DCF estimates value based on projected future cash flows, discounted back to present value:
Business Value = Sum of (Projected Cash Flow in Year N / (1 + Discount Rate)^N) + Terminal Value
This method is favored when a business has strong growth prospects that are not reflected in current earnings. The discount rate accounts for the risk that projected cash flows may not materialize, typically ranging from 15% to 30% for private businesses.
DCF is more complex and subjective than the multiple method because it relies on forward-looking assumptions.
Asset-Based Method
This approach values the business based on its net assets:
Business Value = Total Assets - Total Liabilities
Asset-based valuation is most appropriate for asset-heavy businesses such as real estate holding companies, manufacturing firms with significant equipment, or businesses being liquidated. It tends to undervalue companies with strong brands, customer relationships, or intellectual property, since those intangible assets are difficult to quantify on a balance sheet.
Which Formula Should You Use?
Most business sales in the lower middle market rely on the EBITDA multiple method because it is straightforward, market-based, and widely understood by buyers and lenders. DCF is used as a supplementary analysis or for businesses with unusual growth trajectories. Asset-based valuation serves as a floor value.
In practice, buyers often run all three methods and triangulate a range. As a seller, understanding each formula helps you anticipate how buyers will arrive at their offer.
