About this tool
Customer lifetime value determines how much you can afford to spend on acquisition — without LTV, CAC targets are guesswork.
Calculate LTV and LTV:CAC ratio from order value, frequency, and lifespan inputs.
How to use the LTV Calculator
- 1
Enter average order value, purchase frequency, and customer lifespan.
- 2
Add customer acquisition cost to compute the LTV:CAC ratio.
- 3
Review whether your unit economics support scaling paid acquisition.
Using LTV in growth decisions
LTV:CAC below 1:1 means you lose money on every customer acquired. Above 3:1 typically supports scaling paid channels.
Update LTV inputs quarterly as retention and AOV shift.
Pro tips
- Segment LTV by acquisition channel — not all customers are equal.
- Compare LTV:CAC before increasing ad budgets.
