Free ROAS Calculator for Shopify
Calculate your return on ad spend from attributed revenue and ad spend, then compare it with the break-even ROAS set by your gross margin.
Example and tips
Fictional example: in March, a store spends $2,500 on ads and its campaigns are credited with $10,000 in sales. Its ROAS is 10,000 ÷ 2,500 = 4, or 400%. With a 40% gross margin, its break-even ROAS is 1 ÷ 0.40 = 2.5, and $4,000 - $2,500 = $1,500 of margin remains after ad spend.
- Only compare ROAS figures from the same source and attribution window: Meta and Google can each count the same order.
- Also track a blended ROAS, total revenue ÷ total ad spend: it does not depend on any attribution model.
- ROAS only counts sales inside the attribution window: later repeat orders are missing, so track customer lifetime value too.

How does Free ROAS Calculator for Shopify work?
Calculate your return on ad spend from attributed revenue and ad spend, then compare it with the break-even ROAS set by your gross margin.
Pick a period and a source
Use a full week or month, and take attributed revenue and ad spend from the same source: Meta, Google Ads, Shopify or your analytics tool.
Enter your two amounts
Type the revenue attributed to your ads and the ad spend for the period. The calculator divides the first by the second.
Read your ROAS
The result shows as a multiple, for example 4 for $4 of revenue per $1 of ad spend, and as a percentage, the format Google Ads uses for target ROAS.
Add your gross margin
Tick the option and enter your gross margin: the calculator shows your break-even ROAS (1 ÷ margin) and the margin left after ad spend.
