## What you need to know

### What is customer lifetime value in ecommerce?

Customer lifetime value estimates the revenue, gross margin, or contribution a customer generates across the measured relationship.

### How is customer lifetime value calculated?

Choose a clearly labeled model: revenue CLV, gross-margin CLV or contribution CLV. Estimate value per order, purchase frequency and expected relationship length, then subtract the costs included in that model and validate the estimate against mature cohorts.

### Revenue vs customer lifetime value: what's the difference?

Revenue is sales before costs; CLV estimates value across time and can incorporate margin, returns, service and retention costs.

### Why does customer lifetime value matter?

CLV helps compare acquisition sources, customer groups and retention investments using value over time rather than the first order alone. It also prevents a high first-order revenue figure from hiding expensive returns or service.

### Should CLV include gross margin rather than only revenue?

Usually, because gross margin reflects product cost and gives a more realistic view than sales alone. Contribution CLV can go further by including discounts, returns, rewards, payment, fulfillment, service and retention costs.

### How can customer lifetime value guide acquisition spending?

Use a conservative CLV estimate to set an acquisition ceiling that leaves room for operating cost and profit. Do not spend the full predicted lifetime value upfront when the estimate is uncertain or depends on future purchases.

### How can customer lifetime value guide loyalty rewards?

Set reward cost below the expected incremental contribution the program can create for that segment. Do not fund benefits from revenue-only CLV when margins, returns or service costs differ.

### How can CLV differ by customer segment?

CLV can differ by first product, acquisition channel, geography, purchase frequency, returns and service needs. Calculate it for comparable cohorts and avoid treating a small or young segment as settled fact.

### A quick store check

Calculate revenue-based and margin-based CLV for one cohort, then add returns, rewards and service cost.

## Frequently asked questions

### Can a new store calculate CLV accurately?

It can estimate CLV but should label assumptions clearly and replace them with realized cohort data as history develops.

### Is the highest-CLV segment always the best target?

No. Consider confidence, size, future fit, service demands and the incremental cost of reaching that segment.
