Your ratio and payback
This free CAC payback calculator shows how long a new customer takes to pay back what they cost to get, on gross profit.
Enter your price, your margin and your cost to get a customer. See your payback in months, your LTGP to CAC ratio, and whether a customer covers their cost within the first 30 days.
Here's what CAC payback is, how to work it out, and how to make it shorter.
What is CAC payback?
CAC payback is the time it takes a customer's gross profit to cover what it cost to get them, usually counted in months.
The formula: CAC ÷ (monthly price × gross margin). A customer who costs $200 to get and brings in $40 of gross profit a month pays back in 5 months.
How to use the CAC payback calculator
For a one-time product, leave the box unticked: payback is then counted in purchases.
Why 30 days matters
Most payback benchmarks are counted in months. Alex Hormozi aims for 30 days:
I like to cover my costs of getting a customer within 30 days.
His reason: a month of interest-free money on a credit card can pay for a customer who pays it back inside that month. Then the same money gets the next one, without waiting.

An example
A $49 monthly plan at an 80% margin, with customers costing $200 to get, pays back in about 5 months. Add a $297 setup program in the first month, and the first 30 days change:
- Cash in 30 days
- $49
- Gross profit
- $39.20
- Covers the cost of
- 0.19 customers
- Cash in 30 days
- $346
- Gross profit
- $276.80
- Covers the cost of
- 1.03 customers
The same customer now pays for themselves in the first month, and the monthly plan becomes profit.
How to shorten your payback
Bring more cash in early, from the same customers:
- Charge more up front: a paid start, a setup fee, or a prepaid block of months.
- Add an upsell at the moment of need, in the first 30 days.
- Offer a payment plan instead of a discount to people who say no.
- Bill every 4 weeks instead of monthly: 13 charges a year instead of 12.
