How to Calculate ROAS for Facebook Ads
Facebook Ads ROAS measures how much revenue you earn for each dollar spent on Meta advertising. The formula is: ROAS = Revenue from Facebook Ads / Total Ad Spend. For instance, if you spend $2,000 on Facebook campaigns and generate $10,000 in sales, your ROAS is 5.0x. Meta Ads Manager reports ROAS directly, but you should also consider the attribution window — Facebook defaults to 7-day click and 1-day view attribution. Including only purchase events linked to your ads gives the most accurate ROAS.
