Churn Impact Calculator

The Hidden Cost of Churn

Churn is the silent killer of SaaS businesses. At 5% monthly churn, you lose roughly half your customer base every year — which means you need to acquire that many customers just to stay flat. Every new customer goes towards replacing lost ones before you even begin to grow.

This calculator shows the actual cost of churn per year and what happens when you improve it. Most founders focus on acquisition; the smart ones focus on retention. A 2% reduction in monthly churn often has more impact on your bottom line than a 2% increase in growth rate, because retention compounds just as powerfully as growth does.
