Until the window has passed, part of it is a prediction. Use lifetime profit before ad spend instead of revenue and the same ratio becomes POAS over that window, where 1 is break-even. ## LTV-adjusted ROAS example One campaign, two windows: | Step | Value | | --- | --- | | Ad spend | €1,000.00 | | Revenue from the first orders | €2,500.00 | | ROAS on the first orders (€2,500.00 ÷ €1,000.00) | 2.5 | | Revenue from the same customers over 12 months | €5,000.00 | | LTV-adjusted ROAS (€5,000.00 ÷ €1,000.00) | 5 | | Contribution margin | 30% | | POAS on the first orders (€2,500.00 × 30% ÷ €1,000.00) | 0.75 | | POAS over 12 months (€5,000.00 × 30% ÷ €1,000.00) | 1.5 | On first orders alone the campaign returns 2.5 and loses money at a 30% margin: a POAS of 0.75. Over 12 months the same customers return 5 and a POAS of 1.5. The spend and the customers did not change, only the window.

Two products with the same first-order ROAS can differ here, because one wins customers who come back and the other wins one-off buyers. An account figure blends the two. Plain ROAS is known as soon as the order is. The lifetime figure is only as good as the lifetime value behind it: observed value is complete once the window has passed, and a value used at bid time is a prediction, so check it against observed revenue when the window closes. Bidding can only use the values it receives. Product Metrics sends lifetime value to Google Ads and Meta through Full Signal Tracking, together with profit, revenue, new customers and returning customers, so a returning buyer counts for more than the first basket. ## LTV-adjusted ROAS: common mistake Reading an LTV-adjusted ROAS as money already in the bank. Part of the revenue arrives months after the ad spend, and part of it may still be a prediction, so a campaign can look profitable on lifetime value while it loses money this month. ## LTV-adjusted ROAS: questions ### What is LTV-adjusted ROAS? It is return on ad spend counted on the lifetime revenue of the customers the ads won, not only their first order. €1,000.00 of ad spend that won customers worth €5,000.00 over 12 months is an LTV-adjusted ROAS of 5, even if their first orders brought €2,500.00. Illustrative data. ### How is LTV-adjusted ROAS different from ROAS? ROAS divides the revenue of the orders the ads brought by ad spend, so it stops at the first order. LTV-adjusted ROAS adds the revenue those customers bring later. The two are equal for a customer who never orders again and move apart as repeat orders come in. ### How is LTV-adjusted ROAS different from POAS? POAS divides profit before ad spend by ad spend, so product cost, shipping and fees are taken out. LTV-adjusted ROAS still counts revenue. Put lifetime profit in place of lifetime revenue and you get the POAS version, where 1 is break-even over the window. ### Does Product Metrics send lifetime value to Google Ads? Yes. Full Signal Tracking sends lifetime value to Google Ads and Meta, together with revenue, profit, new customers and returning customers, so bidding on both can value a customer beyond the first order. ## Keep reading - [Return on ad spend (ROAS)](https://www.productmetrics.io/glossary/roas): The first-order ratio this one extends. - [POAS](https://www.productmetrics.io/glossary/poas): The same ratio on profit, with costs taken out. - [Repeat purchase rate](https://www.productmetrics.io/glossary/repeat-purchase-rate): How many customers come back, which sets the gap between the two ROAS figures. - [Predicted LTV (pLTV)](https://www.productmetrics.io/blog/predicted-ltv): How lifetime value is estimated before repeat orders exist, and how to check it. - [CAC and customer lifetime value calculator](https://www.productmetrics.io/cac-ltv-calculator): Work out lifetime value and payback from your own numbers. - [Full Signal Tracking](https://www.productmetrics.io/server-side-tracking): Send lifetime value, profit and revenue to Google Ads and Meta. --- Written by Berend Vrakking, founder of Product Metrics.
