## Why CLV is a north-star metric

Customer lifetime value (CLV) estimates the total profit a typical customer generates over their relationship with your business. It tells you how much you can afford to spend winning and keeping customers. The free [CLV Calculator](https://www.pyalm.com/free-tools/customer-lifetime-value-calculator) works it out fast.

## The formula

CLV = average order value × purchases per year × customer lifespan in years × gross margin %.

A customer who spends AED 250 per order, buys 4 times a year, stays 3 years, at a 60% margin, is worth AED 1,800 in lifetime profit.

## CLV and acquisition cost

CLV only means something next to what it costs to acquire a customer. A common healthy benchmark is an **LTV:CAC ratio of 3:1** — you earn three times what you spend to acquire each customer. Calculate the other half with the [CAC Calculator](https://www.pyalm.com/free-tools/cac-calculator).

## Raising CLV

- Increase average order value with bundles and upsells.
- Improve retention so customers stay longer.
- Protect margin rather than discounting habitually.
