CAC payback = acquisition cost / monthly gross profit

CAC Payback

3.0 months

This is a planning estimate. Retention, refunds, expansion, and operating costs can change the real payback period.

Use CAC payback beside CPA. A low CPA can still be weak if monthly gross profit is too low to recover acquisition cost quickly.

When payback is long, focus creative tests on stronger qualification, better offer framing, or higher-intent audiences before scaling volume.
