What is a customer really worth to you?

Most businesses know what they spend on marketing. Far fewer know what each customer earns them in real profit over time, or how long it takes to earn back what it cost to win them. And many calculate lifetime value from revenue, which makes every customer look more valuable than they are.

The CAC & LTV Calculator Pro shows your true customer economics, channel by channel, so you know where to spend, how much you can afford, and which changes grow customer value most.

See when customers pay you back

A payback chart shows cumulative profit per customer, month by month, against what it cost to win them. Set a target LTV:CAC ratio and see the most you can spend per customer and the monthly budget that still hits it.

Find the lever that grows value most

Pro ranks your best moves: improving retention, raising order value, adding purchases per year, improving margin, dropping a first-order discount, or cutting acquisition cost. A retention and CAC grid shows your ratio at every combination, and you can build your own scenario.

Know where to spend your next dollar

Compare up to 6 channels, segments, or campaigns by CAC, profit LTV, payback, and the lifetime profit each month of new customers creates.
