What this tool does

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 it

  1. 1

    Enter average order value, purchase frequency, and customer lifespan.

  2. 2

    Add customer acquisition cost to compute the LTV:CAC ratio.

  3. 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.

Tips

  • Segment LTV by acquisition channel — not all customers are equal.
  • Compare LTV:CAC before increasing ad budgets.

Frequently asked questions

What is a healthy LTV:CAC ratio?

A ratio of 3:1 or higher is commonly cited as healthy — meaning each customer returns three times what you spent to acquire them.
