What is customer lifetime value (CLV)?

Customer lifetime value, CLV or LTV for short, is the total revenue a customer delivers on average over the entire period they stay with you. Instead of only looking at the first purchase, you add up all the purchases and renewals this customer makes over time. That way you see what a customer is really worth and how much you can responsibly invest to win them.

How do you calculate customer lifetime value?

Customer lifetime value is calculated at its most basic by linking the average revenue per customer to how long that customer stays. In practice you look at three things:

• The average purchase value per customer.
• How often a customer buys or renews their contract.
• How long the customer relationship lasts on average.

Multiply these together and you get a benchmark figure for the value per customer. The full calculation method with examples is in our guide on calculating customer lifetime value.

Why is customer lifetime value important?

CLV helps determine how much you can spend to win a customer. Set it against your customer acquisition cost and you immediately see whether your marketing is paying off. If a customer delivers far more than they cost to win, you can comfortably invest more in growth. If the ratio is skewed, you lose money on every new customer.

At Customer Impact that is precisely why we steer on customers and revenue and not on vanity metrics like reach or clicks. We work exclusively in B2B and never for a webshop, where customer relationships often run for years and the real value only becomes visible once you look beyond the first deal.

How do you increase customer lifetime value?

You increase CLV not by chasing new customers harder, but by making existing customers last longer and become more valuable. Make sure your customers achieve results, because satisfied customers stay longer and buy more.

Work as well on good alignment between marketing and sales, so you attract the right customers from the start. A customer who fits poorly leaves sooner and pushes your average value down. By linking marketing and sales as a small, fast team, you aim for customers who stay, not for a one-off purchase. That turns CLV into a compass that helps you choose where best to spend your budget and attention, rather than a figure you establish after the fact.
