DCF Calculator

Value a fictional company with a discounted cash flow model: change its free cash flow, growth, and discount rate, and see the value per share, the yearly discounted cash flows, and how much comes from the terminal value.

A model values a business as the cash it's expected to generate, with each year's cash converted to today's dollars. This calculator runs one for STU Corp, a fictional company used throughout the Hyperion Entities lessons, with a share price of $50.

DCF sandbox: STU Corp (fictional)

The sandbox discounts free cash flow to shareholders at the discount rate you choose, over a five-year forecast plus a terminal value. It's a teaching tool, not a forecast or a recommendation.

Things to try

  • Raise the discount rate by one point and watch the value per share fall.
  • Change the growth after year five from 3% to 4%. The terminal value usually carries most of the total, so small changes there move the answer a lot.
  • Find the growth rate at which the value equals the $50 share price. That's the idea behind a reverse DCF: what the market price assumes.

What it can't tell you

The arithmetic is exact, but every input is an estimate. A DCF is most useful as a range across reasonable assumptions, and as a way to see which assumptions matter most. Reverse DCF turns the question around.

The lessons behind it

This tool is general education, not personalized investment, tax, or legal advice. It uses simplified assumptions and the numbers you enter.
