Eight small tools that answer the questions sellers ask before touching a bid: what is my ACoS, what can I afford it to be, what should I bid, and how does Flipkart's ROI compare with Amazon's ACoS. Every calculator works in rupees, runs in your browser, and shows the formula so you can check it in Excel.
Start with the three ratios every ad report is built on. They use the same two numbers, ad spend and sales, arranged differently: ACoS as a percentage of ad sales, ROAS as a multiple of spend, and TACoS against total sales so organic growth shows up.
Ad spend and ad sales in, ACoS and ROAS out. The first number every Amazon seller checks.
Learn more →Ad spend against total sales, so you can see whether ads are lifting organic sales or replacing them.
Learn more →Return on ad spend as a multiple, with the matching ACoS, for sellers who think in x rather than %.
Learn more →ACoS on its own says nothing about profit. These two tools bring in price, cost and fees so the target you set is one the product can pay for.
Flipkart's dashboard reports ROI as a multiple rather than ACoS as a percentage. These tools convert between the two and give a PLA bid ceiling from a target ROI.
Before changing bids, run the account through a checklist. The self-audit covers structure, wasted spend, bids and budgets in twelve questions you can answer from the ad console.
These tools work on one product or one campaign at a time. When the same arithmetic needs to run across every keyword in the account, filtered by ACoS or spend and applied in bulk, that is what the software is for.

Break-even ACoS. It tells you the ACoS at which an ad sale makes zero profit, and every other target, bid and ROI number should be set below it.
Yes. The Flipkart ROI and PLA bid calculators use Flipkart's ROI definition (ad revenue divided by ad spend). Shopsy ads run on the same system, so the same numbers apply.
They calculate on the numbers you enter. Marketplace fees attract 18% GST in India, so enter fees inclusive of GST in the break-even calculator if you want the margin to reflect what you actually pay.
