Blended CAC
CAC = sales and marketing spend ÷ new customers. Include the people, tools, agencies, media, commissions, and other acquisition costs from the same period.
Free CAC calculator
Calculate customer acquisition cost and payback.
Calculate blended customer acquisition cost, first-year gross profit, LTV-to-CAC ratio, and estimated CAC payback.
How the calculation works
Use consistent inputs and keep the result in context.
Use gross profit for payback
Revenue is not fully available to repay acquisition cost. This calculator applies gross margin to monthly customer revenue before estimating payback.
Cohorts can tell a different story
A blended average can hide expensive channels or weak customer groups. Compare CAC, retention, and expansion by channel and acquisition month when reliable data is available.
