Amazon TACoS Calculator: Connect Ad Spend to Total Revenue
ACoS tells you half the story. TACoS tells you whether your ads are actually building a profitable business. Nova connects ad spend to total revenue and real margins.
Why ACoS alone is misleading
ACoS only measures ad-attributed sales. TACoS shows the full picture of advertising efficiency.
A 30% ACoS looks terrible in isolation
A 30% ACoS looks terrible in isolation. But if your TACoS is 8% and declining, ads are driving organic growth efficiently. Without TACoS, you'd cut a campaign that's actually working.
Amazon's ad console shows ACoS by campaign
Amazon's ad console shows ACoS by campaign, not product profitability. You can't see if a 25% ACoS product is profitable after COGS and 40+ Amazon fee types. TACoS alone isn't enough.
Manual TACoS calculations use stale data
Manual TACoS calculations use stale spreadsheet data. By the time you pull last week's numbers, ad spend has already shifted. Real-time tracking catches efficiency drops as they happen.
Most sellers only track account-level TACoS
Most sellers track TACoS at account level only. Product-level TACoS reveals which ASINs efficiently convert ad spend into total revenue, and which are just burning through your budget.

What is an Amazon TACoS calculator?
TACoS (Total Advertising Cost of Sale) is the ratio of your total ad spend to your total revenue, including both paid and organic sales. The formula is simple: TACoS = Total Ad Spend / Total Revenue x 100. It's the single best metric for measuring whether your advertising is building a sustainable, profitable business on Amazon.
Unlike ACoS, which only measures the efficiency of ad-attributed sales, TACoS captures the "halo effect" of advertising. Good ads don't just generate direct sales. They improve organic ranking, increase brand awareness, and drive future organic purchases. TACoS captures all of this in one number.
Nova's TACoS calculator goes beyond the basic ratio by connecting advertising efficiency to actual profitability. You see TACoS at the product level alongside real margins after COGS and all 40+ Amazon fee types. This means you can answer the question most tools can't: "Are my ads generating profitable growth?"
