Good CAC payback benchmarks depend on how quickly the business needs cash back.
Payback period shows how long it takes to recover acquisition cost from customer contribution. A subscription company may accept a longer payback if retention is strong. A cash-constrained ecommerce store may need faster payback because inventory and ad spend must be funded again.
Example: If CAC is 60 and first-order contribution profit is 20, first-order payback is incomplete. If the customer usually buys again and adds 45 more contribution profit in the next two months, payback can happen later.
Benchmarks should be judged by margin, repeat purchase timing, cash flow, and growth goals.
Use the Payback Period Calculator at /tools/payback-period-calculator, then compare with CAC at /tools/cac-calculator and LTV at /tools/ltv-calculator.
