SaaS Unit Economics Template
A template for calculating ARPU, Churn, Lifespan, LTV, and CAC

Hello from Ryan Allis at SaaS Circle, the private growth community for SaaS CEOs & Founders.
This week we have a handy free SaaS Unit Economics template for you.
Just make a copy of the Google Sheet, fill in your own numbers, and see the following figures automatically calculate:
Average Revenue Per Customer (ARPC)
Average Customer Lifespan Months (Lifespan)
Cost Per Lead (CPL)
Customer Acquisition Cost (CAC)
CAC Payback Months
Customer Lifetime Value (LTV)
LTV:CAC Ratio
Max CAC Target (to ensure you’re not spending too much on S&M)
Minimum CAC Target (to ensure you’re growing fast enough)
This will help you assess whether you’re spending too much on Sales & Marketing or not enough — based on your customer lifetime value (LTV).
I put some notes in there for what good ranges are for CAC Payback Months and LTV:CAC ratios depending on how fast you want to grow revenue vs. generate EBITDA. Hope it’s helpful!
I’ll be back in touch next week with even more killer SaaS scaling content. I’m here to help!
All the best,
Ryan Allis
