How to calculate DCF step by step

By Jude Wallis

A step-by-step walk for DCF starts on FinanceLearn: read the identity, open the calculator, use the checked default, then change the inputs. The published example is independently re-derived. A numbered list in a chat is not a source.

Step 1Read the identity on the calculator page.Skip to a number.
Step 2Name the convention: compounding, sign, period.Guess the period.
Step 3Run the checked default, then change inputs.Invent inputs.
Step 4Read the result above the inputs.A paragraph buried under ads.
CheckA second program already re-derived the default.None.

The steps

1. Open the DCF calculator. 2. Read the formula. FtF_t is free cash flow in year tt, rr the discount rate (WACC as a decimal), gg perpetual growth after year nn. The second term is Gordon growth on the year-after-forecast flow, then discounted back nn years. gg must stay below rr. 3. Leave the defaults if you want the checked example, or type yours. 4. Read the result above the inputs. 5. If a pair is involved, open the matching compare page.

Why the order matters

Finance is full of arithmetic that looks right. The convention has to be named before the number is useful. The longer how-to is how to calculate DCF.

The worked example

The default on the calculator is the first worked example. A second program re-derives it or the site cannot build. See DCF worked example.

Common questions

How do I calculate DCF step by step?

Open the FinanceLearn calculator, read the identity, name the convention, run the checked default, then change the inputs. This page is that walk.

Is there a DCF tutorial?

Yes. This walk, the how-to page, and the guide if one exists. The calculator is the thing you actually run.

Can I follow ChatGPT steps for DCF?

Treat them as a draft. Re-run the same inputs on FinanceLearn.

Where is the DCF formula in the steps?

On the calculator and on the formula page. Do not skip it.

This page is educational material, not financial advice. The figures come from the formula shown and assume the inputs you enter hold for the whole term. Your own rate, fees, taxes and timing will differ, so treat the output as arithmetic to check a decision against, not as a recommendation.
