A 25% ACoS equals a ROAS of 4, and a 20% ACoS equals a ROAS of 5. Amazon Ads reports both. Teams that also run Google and Meta often prefer ROAS because those platforms use it, while sellers who think in margin tend to prefer ACoS.\n\n### Why it matters\n\nROAS makes channels easy to compare, for example [Sponsored Products](\u002Fglossary\u002Fsponsored-products) against [Amazon DSP](\u002Fglossary\u002Famazon-dsp) or Google Ads sending traffic to Amazon. Break-even ROAS is 1 divided by your margin before ad spend: at a 30% margin it is about 3.3.\n\n### Common mistake\n\nComparing ROAS across ad types without checking the [attribution window](\u002Fglossary\u002Fattribution-window) and whether view-through sales are included. A display campaign that counts views can look far better than a search campaign that counts only clicks. Our comparison of [ACoS, ROAS and TACoS](\u002Fblog\u002Facos-vs-roas-vs-tacos) shows when to use each metric.","What Is ROAS (Return on Ad Spend)?","ROAS (return on ad spend) on Amazon explained: the formula, how it converts to ACoS, break-even ROAS, and why ROAS across ad types can mislead.","acos-vs-roas-vs-tacos","ACoS vs ROAS vs TACoS: Which Metric Should Steer Your Ad Budget","amazon-ppc-management","Amazon PPC Management",[28,32],{"id":11,"slug":29,"term":30,"short_definition":31},"acos","ACoS (Advertising Cost of Sales)","ACoS (advertising cost of sales) is the share of ad-attributed sales spent on advertising, calculated as ad spend divided by ad sales times 100; an ACoS of 25% means $25 of ad spend for every $100 in ad sales.",{"id":12,"slug":33,"term":34,"short_definition":35},"tacos","TACoS (Total Advertising Cost of Sales)","TACoS (total advertising cost of sales) is ad spend divided by total revenue, both ad-attributed and organic, times 100; it shows how much of a brand's whole Amazon business goes to advertising.",[37,42,47,48,53,58,63,68,73,78,79],{"id":38,"slug":39,"term":40,"short_definition":41},"265eb399-2ba5-411c-a1eb-9c41391b3f13","a-plus-content","A+ Content","A+ Content is the section of an Amazon product detail page where brand owners replace the plain product description with images, comparison charts and formatted text modules; it requires Brand Registry.",{"id":43,"slug":44,"term":45,"short_definition":46},"87df8b1f-4811-4e07-9171-63fd4923c405","a9-algorithm","A9 Algorithm","A9 is the common name for Amazon's product search ranking algorithm, which decides which products appear for a search and in what order, based mainly on relevance to the query and the product's sales performance.",{"id":11,"slug":29,"term":30,"short_definition":31},{"id":49,"slug":50,"term":51,"short_definition":52},"aaa36c94-6a2a-4d4c-800c-fa1d48c8684b","brand-registry","Amazon Brand Registry","Amazon Brand Registry is Amazon's program for trademark owners that gives them more control over their product listings, access to brand-only advertising and content tools, and tools to report counterfeits and infringement.",{"id":54,"slug":55,"term":56,"short_definition":57},"9b5c7c9a-d511-4c8e-9774-2307ec4add2c","storefront","Amazon Storefront","An Amazon Storefront, officially called an Amazon Store, is a multi-page branded shopping destination on Amazon with its own URL, available at no cost to brands enrolled in Brand Registry.",{"id":59,"slug":60,"term":61,"short_definition":62},"a65df449-1de8-4ad2-8ec4-7973fb32f59b","vine","Amazon Vine","Amazon Vine is an invitation-only review program where Amazon sends products from enrolled brands to trusted reviewers, called Vine Voices, who get the item at no cost in exchange for an honest review.",{"id":64,"slug":65,"term":66,"short_definition":67},"230b5a40-78dc-443c-a421-a29a8d1c8efb","asin","ASIN","An ASIN (Amazon Standard Identification Number) is the 10-character alphanumeric code Amazon assigns to each product in its catalog; it identifies one detail page that every seller of that exact item shares.",{"id":69,"slug":70,"term":71,"short_definition":72},"56722521-a391-4396-a435-80460d0ec95d","buy-box","Buy Box","The Buy Box is the purchase panel on an Amazon product page with the Add to Cart and Buy Now buttons; when several sellers offer the same product, Amazon decides whose offer fills it and now calls it the Featured Offer.",{"id":74,"slug":75,"term":76,"short_definition":77},"3ce8cb16-1838-4b86-a5b5-3eaa1110bc31","fba","FBA (Fulfillment by Amazon)","FBA (Fulfillment by Amazon) is the Amazon program where you send inventory to Amazon's fulfillment centers, and Amazon stores it, picks, packs and ships each order, and handles customer service and returns for those units.",{"id":4,"slug":5,"term":18,"short_definition":19},{"id":12,"slug":33,"term":34,"short_definition":35},1793651103941]
