Revenue Impact of Churn Calculator

Churn doesn't just remove customers. It removes the compounding revenue those customers would have generated. Every churned subscriber is a future month of revenue you'll never collect. And the gap between your current trajectory and a lower-churn alternative widens every single month.

That's why even a modest improvement in retention (halving your churn rate from 5% to 2.5%, for example) can translate to hundreds of thousands of dollars in additional revenue over two or three years. The chart above makes this viscerally clear.

Why this matters more than acquisition

Most SaaS companies focus disproportionately on acquisition. But the maths favours retention:

• Reducing churn by 1% has the same MRR effect as increasing acquisition by 5–10% (varies by business)
• Retained customers cost nothing to re-acquire
• Long-tenured customers are more likely to expand and refer
