Payback Period Calculator
Enter your Customer Acquisition Cost and monthly revenue per customer to instantly calculate how many months it takes to recover your acquisition investment.
How to Use This Calculator
Payback period tells you how quickly you recover the cost of acquiring a customer. It is a critical metric for SaaS, subscription, and recurring revenue businesses.
Enter your CAC
Input your average customer acquisition cost. This is your total marketing and sales spend divided by new customers acquired in the same period.
Enter monthly revenue per customer
Use average monthly recurring revenue (MRR) per customer, or average monthly spend if you are not a subscription business. Use gross margin-adjusted revenue for a more accurate payback.
Read your payback period
The result shows how many months it takes to recover what you spent to acquire a customer. Under 6 months is excellent; 6–12 months is acceptable for most growth-stage businesses.
Use payback to make budget decisions
A shorter payback period means faster capital recycling and lower funding risk. If payback exceeds 12 months, focus on reducing CAC or increasing monthly revenue per customer.
