AOV vs LTV: how they work together

2026-05-20 11:48 · Paid Marketing

AOV and LTV measure different parts of customer value. Learn how average order value affects lifetime value and acquisition decisions.

AOV and LTV both describe customer value, but they measure different levels of the relationship.

AOV means average order value. It shows the average revenue from one order. LTV means customer lifetime value. It estimates how much revenue or gross profit a customer produces over the full relationship.

AOV is one input that can affect LTV. If customers buy the same number of times but each order becomes larger, lifetime value usually increases. But AOV alone does not show repeat purchase behavior, retention, margin, or acquisition cost.

For ecommerce, AOV is useful when testing bundles, product recommendations, free shipping thresholds, discounts, and paid campaign quality. LTV is more useful when deciding how much you can afford to spend to acquire and retain customers.

A practical workflow is to calculate AOV with the AOV Calculator at /tools/aov-calculator, then use the LTV Calculator at /tools/ltv-calculator to see how order value, purchase frequency, lifespan, and margin work together. CAC, CPA, ROAS, and ROI help connect customer value back to acquisition cost.
