Customer lifetime value calculator
Customer lifetime value (CLV) is what a customer is worth across the whole relationship, not just one order. Multiply average order value by purchase frequency by expected lifetime — then apply your margin to see the profit each customer brings.

Your numbers
CLV = average order value × orders per year × years retained, adjusted for gross margin.
Inputs stay in your browser. ClientTell tracks retention and health signals that extend lifetime — automatically, from your own feedback data.
After applying your 70% gross margin, each customer is worth $1,071 in profit over an average 3 year relationship.

Why CLV changes how you spend
Every acquisition, retention and expansion decision is a comparison between what a customer costs to win and what they are worth over time. CLV is the denominator in that comparison — and the number that justifies investing in keeping customers.
It sets your acquisition ceiling
If a customer is worth $600 over their lifetime, spending $80 to acquire one is cheap and $500 is ruinous. Without CLV, acquisition budgets are set by optimism rather than arithmetic.
It exposes retention’s true value
Extending average lifetime from 2 to 3 years lifts CLV by 50% with no new customers at all. Retention work stops looking like a cost centre once it is priced in these terms.
Segment it or it lies
A blended CLV hides the story — one loyal segment may be worth ten times another. Calculate CLV per acquisition channel and plan tier to see where to double down.
