Reducing churn from to increases LTV by per customer.

Enter ARPU and churn rate above.

How LTV Is Calculated

LTV = ARPU ÷ Monthly churn rate
Avg lifespan = 1 ÷ Monthly churn rate
LTV:CAC ratio = LTV ÷ CAC

Churn reduction has more leverage on LTV than price increases. Cutting churn in half doubles LTV; doubling price only doubles LTV if no customers leave.
