# Customer Lifetime Value

Customer lifetime value is the total revenue a single customer generates over the entire span of their relationship with your company. It is a forward-looking measure of customer worth, combining purchase behavior, retention, and profitability into one number. A higher CLV means each customer relationship is more valuable, which justifies spending more to acquire and keep them.

**Formula:** Average purchase value × Purchase frequency × Average customer lifespan

## How is customer lifetime value calculated?

The standard formula has three inputs:

| Input                     | Definition                                                            |
| ------------------------- | --------------------------------------------------------------------- |
| Average purchase value    | Total revenue / Number of purchases over a period                     |
| Purchase frequency        | Number of purchases / Number of unique customers over the same period |
| Average customer lifespan | Average number of years a customer stays active                       |

Multiply all three together to get CLV. For example, if a customer spends 50 dollars per order, orders twice a year, and stays for five years, the CLV is 50 × 2 × 5 = 500 dollars.

## Why does customer lifetime value matter?

CLV tells you how much a customer relationship is actually worth, which informs how much you can afford to spend acquiring and supporting them. It shifts the focus from short-term conversions to long-term retention and upsell. For support teams, it makes the case for investing in better experiences: every improvement that keeps a customer around longer, or that encourages repeat purchases, raises CLV.

## Frequently asked questions

### What is a good customer lifetime value?

It depends on your industry and average order value. What matters is the ratio: CLV should be at least three times higher than customer acquisition cost. A rising CLV over time signals stronger retention, more repeat purchases, or successful upsells.

### How is customer lifetime value calculated?

Multiply average purchase value by purchase frequency, then multiply by average customer lifespan. For example, if a customer spends 50 dollars per order, orders twice a year, and stays for five years, CLV is 500 dollars.

### Why does customer lifetime value matter for support teams?

Support quality directly affects retention and repeat purchases. A single bad experience can cut CLV short. High-CLV customers justify more investment in personalized support, while efficient self-service scales help for the broader base.
