DCF Valuation

A company is worth the cash it will generate — discounted back to today. Build a DCF and watch how growth and discount rate swing the value.

Presets

Discounted cash flow values a business as the present worth of all its future cash. Distant cash is worth less because of the discount rate, and a terminal value captures everything beyond the forecast horizon. Educational tool, not financial advice.

Governing equation

Reading this result: A 2.0-point gap between discount and growth shrinks each later year of present value; the terminal still accounts for 57% of the total.

How it works

Discounted cash flow sums the present value of forecast cash flows, discounting distant cash more heavily, and adds a terminal value for everything beyond the horizon. The discount rate and terminal growth assumption dominate the result — small changes move the valuation a lot. Educational tool, not financial advice.

Frequently asked questions

Is this dcf valuation calculator tool really free?
Yes. DCF Valuation runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
