Customer Lifetime Value Calculator

There are, and some are fine. The difference is what has been checked. This file was built from scratch, then every formula in it was recalculated by a separate checker that compares each result against an independently worked-out answer — 52 of them here. A template that looks right and totals wrong is worse than no template at all, and that is the usual failing of one downloaded from a search result.

It also opens with sample rows already filled in, so you can see every formula working before you touch it, and it is set up to print without fighting the page setup. No email wall, no signup, no watermark, and you can use it commercially.

Knowing what a customer is worth tells you how much you can afford to spend winning one. This Excel customer lifetime value calculator works out average customer life from monthly churn, then lifetime value from revenue and gross margin, for each customer segment.

It compares lifetime value with acquisition cost, shows the LTV to CAC ratio and payback period, and marks each segment Healthy, Thin or Losing money.

Average customer life is 1 ÷ monthly churn. LTV is margin-adjusted revenue over that life, and the last two columns say whether the acquisition spend is justified.

The file opens with sample rows so you can see every formula working before you change anything. Type your own figures over them. When you need more rows, insert them inside the existing block rather than underneath it, so the totals keep covering every row.
