Churn Rate Calculator

Churn Rate Calculator is part of Toolspire and is ready as soon as this page loads. The denominator is the opening count, not the average and not the ending count. New customers acquired during the period are not in this formula.

What you can do here

Opening balance is the base

Ending customers would hide the people who left and were replaced.

Logo churn, not revenue churn

Each customer counts as one. A huge account and a tiny one weigh the same.

One period

Ten lost in a month is a monthly rate. Do not compare it with a yearly 5% without saying so.

The sequence

How to use the Churn Rate Calculator

  1. 1

    Count who was a customer on day one

    That is the denominator. People who joined on day two are not in it.

  2. 2

    Count who left and did not return in the period

    A pause you still call active is not churn until your own rule says it is.

  3. 3

    Keep the period in the sentence

    The page prints a percent. You have to remember whether the 200 was a month or a year.

Worth knowing

  • Churn Rate Calculator on Toolspire: churn = lost ÷ opening customers × 100.
  • 10 ÷ 200 = 5%.
  • Lost customers above the opening count are rejected.
  • New signups do not reduce this rate. They are a separate count. A firm can churn 5% and still grow.

Replacement customers do not cancel churn

If 200 people started the month and 10 of them left, churn is 5% even if 40 new people arrived. Growth and churn are different sentences. Revenue churn, which weights big accounts, needs revenue in both boxes and is not what this count does. The page treats every customer as one.

FAQ

Questions about Churn Rate Calculator

Where does Churn Rate Calculator run?

Churn Rate Calculator runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

What is churn if 10 of 200 leave?

5%.

Do new customers lower the rate?

Not in this formula. They were not in the opening 200.

What if I use the ending count as the base?

You would be answering a different question, and a replaced customer would hide a loss. This page will not do that.

Is 5% a month the same as 5% a year?

No. The page does not annualise. Label the period yourself.
