When a business metric is discussed in percentages, ratios, or “per unit” terms, the arithmetic can hide the practical meaning. Business Valuation Calculator keeps that calculation visible and easy to audit.

What this calculator does

Business Valuation Calculator estimates business equity value using either an earnings-multiple approach or the calculator’s perpetual-growth approach, then adjusts for debt and cash. The result is deliberately tied to the fields on this page, so it represents this calculator’s model rather than a broader financial analysis with unentered assumptions.

How to use it

Enter Currency, Valuation method, Normalized annual earnings or cash flow, Selected earnings multiple, Long-term growth rate (%), Discount rate (%), and the remaining displayed fields. Use figures from the same reporting period and the same accounting, workforce, inventory, or campaign definition wherever possible. The currency selector changes display currency only; it does not perform an exchange-rate conversion. Before using the result in a decision, recheck unusually large or negative values against the source data rather than assuming the calculator is correcting an inconsistent input.

How the calculation works

The multiple method estimates operating value as normalized earnings × selected multiple. The perpetual-growth branch uses earnings × (1+g) ÷ (discount rate−g), which requires the discount rate to exceed long-term growth. Equity value then adds cash and subtracts debt.

Example

Using the default earnings-multiple branch, $200,000 of normalized earnings × 4 gives an operating value of $800,000. With no debt or cash adjustments, the simplified equity value is also $800,000.

How to interpret the result

The result is best used as a decision-support threshold or valuation scenario. It becomes more informative when you compare several assumptions, because a small change in price, margin, growth, discount rate, cash flow, or capital requirement can materially change the conclusion.

Limitations and notes

Valuation is highly assumption-sensitive. This page models only the earnings-multiple/perpetual-growth inputs shown; it does not build a full multi-stage DCF, asset appraisal, comparable-company set, or transaction model. Long-term growth must remain below the discount rate in a perpetual-growth calculation.
