Churn & LTV Predictor
For any seller running a subscription, membership, or repeat-purchase model, churn is the number that quietly determines whether marketing spend is sustainable. This calculator takes your monthly recurring revenue, total customer count, and cancellations for the period, and instantly returns your churn rate, average customer lifespan in months, and lifetime value - the figure that should be compared against acquisition cost before scaling ad spend further.
Enter MRR, total customers, and monthly cancellations to instantly see your churn rate, average customer lifespan, and lifetime value.
Frequently Asked Questions
How do you calculate churn rate?
Divide the number of customers who cancelled during a period by the total number of customers at the start of that period, then multiply by 100 for a percentage.
How is customer lifespan calculated from churn rate?
Average lifespan in months is 100 divided by the monthly churn rate percentage. A 5% monthly churn rate implies an average customer lifespan of 20 months.
What’s the difference between this and the Customer Lifetime Value calculator?
This tool is built specifically for subscription/recurring sellers and derives lifespan directly from churn rate. The Customer Lifetime Value calculator is for B2B sales contexts where you already know an estimated lifespan and want to factor in gross margin and CAC directly.
