How the Math Works

What This Calculator Is Actually Measuring

Churn rate is simple in theory and expensive in practice. Here's what each number means and why it matters for your growth.

Output 01

Monthly Churn Rate

Calculated as customers lost divided by customers at the start of the month. Even a 5% monthly churn rate means you're replacing nearly half your customer base every year just to stay flat. That's an acquisition treadmill no company can outrun forever.

Output 02

Annual Churn Rate

This is not simply monthly rate times 12. The correct formula compounds the loss: 1 minus (1 minus monthly churn) to the power of 12. At 5% monthly churn, your annual churn is 46%, not 60%. The difference matters for forecasting.

Output 03

MRR Saved at Target

This is where the calculator gets useful. Every fraction of a percent you reduce churn compounds over time. Set your target and see the monthly and annual MRR you'd recover. For most SaaS companies, even a 1% improvement in churn is worth more than a significant increase in new customer acquisition.
