Customer lifetime value — CLV / LTV

The total revenue a customer brings over the whole relationship with your business.

What it means

Customer lifetime value, often shortened to CLV or LTV, is the total money a customer spends with your business from their first purchase to their last. Instead of looking at one sale, it looks at the whole relationship.

A customer who buys a ₹200 coffee once is worth ₹200. A customer who buys that coffee every week for three years is worth much more.

How it works

A simple beginner formula is:

CLV = average order value × purchases per year × years as a customer

• Average order value: how much a customer spends each time.
• Purchases per year: how often they buy.
• Years as a customer: how long they usually keep coming back.

This uses revenue. You can also use profit instead, which shows what a customer is really worth.

CLV is most useful when compared with CPA (cost per acquisition), which is how much you spend on marketing to win one new customer. If CLV is comfortably higher than CPA, your marketing can be profitable over time.

A simple example

A café in Pune finds that a regular customer spends about ₹250 per visit, visits 40 times a year and stays loyal for around 3 years.

CLV = ₹250 × 40 × 3 = ₹30,000

If the café spends ₹500 on Instagram ads to win one new regular, that CPA is tiny compared with ₹30,000.

Why it matters

CLV changes how you think about marketing. It shows that keeping customers happy is just as important as finding new ones. It also shows how much you can safely spend to win a customer.

Beginner tips

• Use real sales data, even a rough estimate from your billing records.
• Calculate CLV separately for different customer types if you can.
• Improve CLV with loyalty offers, good service and helpful follow-up emails.
• Common mistake: judging a campaign only on its first sale and ignoring repeat purchases.
