What is blended ROAS and how do I calculate it for my boutique?
Blended ROAS is your total ad-attributed revenue divided by your total ad spend across all platforms. It tells you how many dollars you earned back for every dollar spent on advertising.
“Below two, you're probably losing money after costs. Two to four is functional. Above four is strong.”
Blended ROAS combines all your advertising platforms into one number so you can see the overall return on your ad investment. To calculate it, log into each ad platform separately — Meta Ads Manager, Google Ads, TikTok Ads — and write down your total spend from each for the period you're measuring. Add those together for your total ad spend, then divide your total ad-attributed revenue by that number.
As a general guideline, below two means you're likely losing money after accounting for product costs and overhead. Two to four is functional, and above four is strong. The tricky part is that Shopify and Meta often report different revenue numbers from the same ads.
Use Shopify's number as your conservative floor and Meta's as the optimistic ceiling. If the gap between them exceeds fifty percent, create unique discount codes per platform — like META10 and GOOGLE10 — and track redemptions in Shopify for a cleaner, platform-independent attribution picture.
