How to Calculate Customer Acquisition Cost

CAC is everything you spend to win customers divided by the number you win in the same period. "Blended" CAC counts all spend and all new customers, including ones who found you on their own.

CAC = (marketing + sales spend) ÷ new customers
CAC payback (months) = CAC ÷ monthly gross profit per customer

Tips

Use a period long enough to smooth out lag between spend and sign-ups. Compare CAC with customer lifetime value; see the CLV calculator.
