Amazon PPC Calculator Suite by Sequence Commerce

About

The free Amazon PPC calculator suite built by an agency managing $500M+ in Amazon ad spend.

Sequence Commerce's PPC Calculator Suite puts the three metrics every Amazon advertiser relies on, ACoS, ROAS, and TACoS, into one fast side panel alongside breakeven calculations and real category benchmarks. Open it next to Seller Central or Campaign Manager, enter your numbers, and get instant, accurate answers. No spreadsheets, no signup, and no data leaving your browser.

We built it because we use it. Sequence Commerce runs Amazon PPC and full-account management for more than 100 brands, including Heinz, Nestlé, Catelli, and Joe Boxer, and these are the exact calculations our team performs every day. Now they're free for every seller.

Four tools in one side panel

ACoS Calculator: Enter your ad spend and ad-attributed sales to calculate your Advertising Cost of Sales instantly. You'll also see your breakeven ACoS based on product price, Amazon fees, shipping costs, and target margin so you know exactly how much you can spend before profitability disappears.

ROAS Calculator: Enter ad spend and attributed revenue to instantly calculate Return on Ad Spend.

TACoS Calculator: Factor in product price, Amazon fees, shipping, and product costs to calculate Total Advertising Cost of Sales, profit margin, target ACoS, and projected profit at your target ACoS. It's the metric that shows whether your overall business is truly profitable.

Category Benchmarks: Compare your ACoS and ROAS against real benchmarks across categories including Apparel, Beauty, Grocery, Electronics, Pet Supplies, Sports, Supplements, Industrial, and more. Benchmarks are segmented by Branded vs. Launch campaigns and fulfillment type, helping you quickly determine whether your performance is healthy or needs improvement.
