What is payback period in DTC?

Payback period = how many months of customer gross profit it takes to recover the CAC spent acquiring them. Under 6 months = healthy. Over 9 = stressed.

The formula

Payback period (months) = CAC / monthly gross profit per customer.

Example: $60 CAC, $25/mo gross profit per customer → 2.4 month payback. Shorter is better.

Why it matters more than LTV:CAC

LTV:CAC tells you whether unit economics work eventually. Payback tells you when you get cash back. A brand with great LTV but 14-month payback runs out of cash before the LTV materializes.

Payback is the metric that determines how much you can spend on acquisition without external funding.

Healthy ranges

Under 6 months = healthy DTC. 6-9 months = stressed but workable if you have cash. 9-12 months = you need external funding to scale. Over 12 months = your unit economics don't work for paid acquisition.
