See what a customer is really worth. Enter the average order, how often they buy, how long they stay, and your margin — and get lifetime value in revenue and in profit.
A simple LTV model — it assumes steady spend, frequency, and retention. Real customers vary; use it to compare segments and set an acquisition budget, not as a promise.
Lifetime value is what a customer is worth in profit over the whole time they buy from you. It sets the ceiling on what you can afford to spend to acquire one — a common rule is to keep customer acquisition cost under a third of LTV.
Multiply average order value by purchases per year by years retained to get lifetime revenue, then multiply by your gross margin for profit LTV. This calculator shows both and a suggested max acquisition cost.
Because revenue isn't profit. A customer who generates $600 in revenue at a 60% margin is worth $360 to you — that's the number your acquisition spend has to stay under.
