§ How to use

How to calculate SaaS CAC, LTV and payback

Calculate Customer Acquisition Cost, Lifetime Value, payback and the LTV/CAC ratio — essential SaaS metrics.

Enter acquisition spend
Sum marketing, sales and tools. Divide by customers acquired in the period = gross CAC.
Enter ARPU and margin
Monthly ARPU and gross margin % (price - direct cost). Used for LTV: ARPU × margin ÷ churn.
Enter monthly churn %
Cancellations / customers at the start of the month. For healthy B2B SaaS, churn is <5% monthly.
Analyze the indicators
LTV/CAC >3 is the healthy target. Payback <12 months is ideal. If LTV/CAC <1, you burn cash on every customer.
