Valuation calculators

8 calculators, free and without an account. Each one shows the formula it uses, works through an example, and says what people usually get wrong with it.

Valuation

Discounted cash flow calculator

Project a company's free cash flow forward five years, discount it back, and see what the business is worth today.

Reverse DCF calculator

Take today's market value as given and solve for the growth rate the price is already assuming.

Terminal value calculator

Value everything beyond the forecast period, by perpetuity growth or by an exit multiple.

Margin of safety calculator

Compare an estimated value to the price being asked, in both conventions people use for it.

Cost of capital

WACC calculator

Blend the cost of equity and the after-tax cost of debt into the single discount rate a DCF needs.

CAPM calculator

Estimate the return shareholders should demand, given the risk-free rate, the equity risk premium and the stock's beta.

Cash and growth

CAGR calculator

The single annual rate that would take a starting value to an ending value over a given number of years.

Free cash flow calculator

Operating cash flow less capital expenditure: what the business actually generated for its owners.

Every result depends entirely on the assumptions you type in. These are tools for thinking with, not valuations, and nothing here is investment advice. Materialitydoes the same arithmetic on a company's real filings.
