What is customer lifetime value (CLV), and why does it change what you can spend on ads?
Customer lifetime value (CLV, or LTV) is the total a customer is worth to your business over the whole time they keep buying from you, not just their first order. If customers come back, you can afford to pay more to win each one than a single sale would suggest.

How do I work out CLV simply?
A common simple version:
CLV = average order value × orders per year × years they stay a customer
For a truer picture, multiply by your profit margin so you're working with profit, not sales.
A made-up example
This is an illustrative example, not a benchmark. Imagine a Kuwait perfume shop where:
| Item | Example figure |
|---|---|
| Average order | 20 KWD |
| Orders per year | 3 |
| Years as a customer | 2 |
| Revenue CLV | 20 × 3 × 2 = 120 KWD |
| Profit margin | 40% |
| Profit CLV | 48 KWD |
If you only look at the first order (20 KWD at 40% margin = 8 KWD profit), paying 10 KWD to get a customer looks like a loss. Using CLV, that same 10 KWD buys a customer worth 48 KWD in profit over time.
Why does it change ad spending?
It changes the question from "did this ad pay back today?" to "did it bring customers worth more than they cost?" That's why a ROAS figure from the first purchase alone can make a good campaign look weak. It also helps set a sensible marketing budget.
Google's tools reflect this too. Google Analytics Help describes a user lifetime view showing behaviour and value "over their lifetime as a customer". Google Ads Help says its customer lifecycle goals help "increase value from both new and existing customers".
The honest caveat
CLV is only as good as your data. A new business has little repeat history, so use cautious numbers and update them as real repeat orders come in.
