Customer Acquisition Cost (CAC) and Lifetime Value (LTV) measure how efficiently you acquire and retain customers. Use this free calculator to compute CAC, LTV, the LTV/CAC ratio, and CAC payback period.
A healthy LTV/CAC ratio is 3.0 or higher, and CAC payback under 12 months is considered strong for B2B SaaS. Below 1.0 LTV/CAC indicates unprofitable acquisition.
DealARR calculates LTV, CAC, and payback automatically from your deal book and S&M spend, segmented by channel, segment, and cohort.
