What a customer is actually worth
Lifetime Value is a customer lifetime value calculator for the ecommerce shop — what a customer is worth, how that builds after they arrive, and whether the ones you're winning now are worth what earlier ones were — cumulative spend by cohort, by order count, and broken down by everything from first product to acquisition channel.
The customer lifetime value calculator: age the cohort before you trust its curve
LTV by cohort: cumulative spend per customer in the months after their first order, in EUR — summed across cohorts before dividing, so a 900-customer month isn't weighted the same as a 9-customer one. Only cohorts older than 90 days are averaged; a two-week-old cohort hasn't had time to accrue what its curve will eventually show.
- ✓What a customer becomes worth — cumulative spend per customer in the months after their first order, in EUR, only from cohorts old enough to mean something.
- ✓90-day floor — cohorts under 90 days are excluded from the average; including them drags every month toward the floor.
- ✓Is it getting better or worse — what one customer from each acquisition month has spent so far, each bar carrying its own age so recent months aren't unfairly compared.
- ✓One order against many — a customer who orders twice is worth 1.7x one who orders once, 42.19 against 25.23 EUR.
- ✓Later buckets describe, they don't prove — long-tenured customers have simply had more time both to order and to accrue value; the chart can't separate the two, so treat order-count buckets past the first step as descriptive, not causal.
- ✓How long they stay, and how many are gone — average time from first order to last, against the share of the cohort lost, using this shop's own median gap between orders as the churn threshold.
- ✓Cohort payback, without extrapolation — customers, months observed, blended acquisition cost, and the month cumulative contribution covered it; cost is all-channel ad spend since individual customers aren't attributed to a platform, and payback is never projected past what's actually been observed.
- ✓Who carries it — every customer placed by total spend; a handful of buyers routinely carry a third of the total, pulling the average above most of the shop.
How long customers stay, and how many are already gone
Average time from a customer's first order to their last, plotted against the share of that cohort the shop has since lost. Lost is this shop's own threshold, derived from its median gap between orders — a fixed number of days would call a slow shop's healthy customers churned when they're simply on a longer cycle.
Seven ways to ask the same question
By what they first spent, the first product they bought, the category they arrived through, the brand, the market, whether they're a company or a consumer buyer, and the channel or campaign they arrived through — every breakdown shares the same Spent (blue) / Kept (green) pattern, drawn from the same customers, so the cuts can never disagree about what the shop is worth. By first spend, customers who opened over 100 EUR average 141.32 EUR lifetime against 14.66 EUR for those who opened under 25.
