LTV:CAC Calculator — free online

You spend money to win a customer, and you earn money back over time. The hard part is knowing if those two numbers are healthy together. Is each customer worth more than what you paid to get them? We added a free tool that does the math for you — LTV:CAC Calculator — right in your browser.

What it does

You type in a few numbers about your customers and your spend. It works out the customer lifetime value, the LTV:CAC ratio, and how many months it takes to earn back what you paid to get a customer (CAC payback). That's it — clear numbers you can act on.

Nothing leaves your device

The whole thing runs inside your browser. Your figures are never uploaded and nothing is saved anywhere. When you close the tab, it's gone. You can use it on real business numbers without worrying.

How to use it

  1. Open the LTV:CAC Calculator in your browser.
  2. Fill in your customer value, costs and how long people stay.
  3. Read the LTV, the LTV:CAC ratio and the payback in months.

It's free with no limit. There are more small tools on the Apps page.
