Churn cost

What a leaky month actually costs, and how many new buyers you need just to stand still.

The leak

$71

MRR walking out this month

Seats to replace
2
Seats lost in a year
17
Current MRR
$1,176
Year of that leak
$847

You have to find 2 new paying customers every month just to stay flat. Growth starts after that.

Growth starts after the leak

Monthly seats lost = customers × churn. That is how many new paying people you need before MRR can rise. Early on, 3–7% a month is common. The work is talking to the ones who left.

Worked example: 24 customers at $49. $1,176 MRR. At 6% churn you lose about 1.4 seats and $71 this month. Over a year that is roughly 17 seats and $850 of MRR you have to replace just to stand still.

FAQ

Questions people get stuck on

What is a good churn rate with 20 customers?

With twenty people, one cancel is 5%. That is a conversation, not a dashboard. Talk to the person who left before you hire a “retention” tool.

Do annual plans hide churn?

They delay it. Count logo churn when the contract ends, and still watch who stops using the product in month two.

Should I include people on a free plan?

No. Free users who leave teach you about free users. This calculator is for people who paid.

How do I lower it?

Ask who left. Fix the job they hired you for. Do not add a feature to avoid the email.
