What Is Customer Lifetime Value?

Customer lifetime value is the total profit a business expects to earn from one customer over the whole relationship.

In plain English

It is the number that decides what you can afford to spend on acquisition. Without it, every marketing budget is set by feel.

It is also easy to inflate. Optimistic retention assumptions and revenue counted instead of profit produce a figure that justifies spending you cannot actually sustain.

What to know

Profit, not revenue
Margin after delivery costs, or the figure misleads.
Retention-driven
Small changes in churn move it substantially.
Sets the acquisition ceiling
What you can afford to pay for a customer.
Segment it
Different customer types have very different values.

Why it matters

Knowing lifetime value changes which channels are viable. A business that can afford three times what a competitor can pay per customer wins the auction, and lifetime value is what creates that room.

Common mistakes

×Using revenue instead of profit.
×Optimistic retention assumptions.
×One blended figure across very different customer types.
×Calculating it once and never updating it.

FAQs

A period you have evidence for. Two or three years is usually the limit of honesty.

What raises lifetime value fastest?

Retention, then increasing purchase frequency. Both beat raising prices in most cases.
