CAC payback calculator
Estimate how long gross profit takes to repay CAC.
Calculate current payback, then model how a lower acquisition cost changes the recovery period.
Where the work changes.
Treat the output as a decision input
A calculator makes assumptions visible. It does not replace attribution quality, margin context or direct account review.
Questions before the audit.
- How is CAC payback calculated?
- Divide customer acquisition cost by monthly gross profit per customer.
- Why use gross profit instead of revenue?
- The direct cost of serving the customer reduces the amount available to recover acquisition spend.
- Does the model include churn?
- No. It is a simple recovery-period view. Use the LTV calculator to examine churn and longer-term customer value.
Calculate from your numbers.
Monthly gross profit equals monthly revenue per customer multiplied by gross margin. CAC payback divides acquisition cost by monthly gross profit. The modeled view reduces CAC by the selected rate.
Review what controls the payback period.
We will trace acquisition cost and customer economics back to the account decisions behind them.
