How to estimate a small business valuation

Start with the purpose

A valuation prepared for a sale, fundraising discussion, insurance decision, or internal planning exercise may use different assumptions. Before calculating anything, define who will use the estimate and what decision it needs to support. A planning estimate can be broad; a legal or tax valuation may require a credentialed professional and formal documentation.

Revenue is not value

Revenue shows scale, but buyers ultimately care about the cash the business can produce after the costs required to operate it. Two companies with identical revenue can have dramatically different values when one has stronger margins, recurring contracts, diverse customers, and a management team that does not depend on the owner.

Three common approaches

Earnings multiple

Normalize annual earnings by removing unusual, one-time, or owner-specific items, then apply a market multiple. Smaller owner-operated businesses often discuss seller’s discretionary earnings, while larger operations may use EBITDA. The difficult part is not multiplication; it is choosing defensible normalized earnings and a comparable multiple.

Revenue multiple

Revenue multiples can be useful when profits are intentionally low because the company is investing in growth, or when recurring revenue provides unusually strong visibility. They are weak when revenue is project-based, concentrated, low-margin, or expensive to retain.

Discounted cash flow

A discounted cash-flow model forecasts future cash and adjusts it for time and uncertainty. It can be powerful, but small changes in growth, terminal value, or discount rate can move the answer sharply. Use scenarios rather than one optimistic forecast.

What increases a multiple?

• Repeatable revenue with low churn
• Diverse customers and suppliers
• Documented processes and clean financial records
• Defensible differentiation or intellectual property
• A capable team that can operate without the owner

Example

Imagine a company with $1.2 million in annual revenue, a 22% profit margin, and 18% annual growth. A simplified model may produce an estimate around $1.5 million. That figure should be stress-tested: reduce growth, adjust profit for a market-rate owner salary, and apply a discount for customer concentration. The range across scenarios is often more informative than the center estimate.

Common mistakes

Avoid using a multiple from a headline transaction without comparing size, geography, margins, growth, and deal terms. Do not count the same benefit twice—for example, increasing the earnings forecast and also using a growth-premium multiple. Finally, distinguish enterprise value from the amount an owner receives after debt, cash, taxes, and transaction costs.

Use the Business Valuation Calculator to create a baseline. Then prepare conservative, expected, and optimistic scenarios and document why each assumption could occur.
