How to use this tool

  2. Enter ads and orders Ad spend, orders and average order value from Ads Manager. Tick if you claim back the GST on ads.
  3. Add costs and COD returns Product cost, gateway fee, shipping, packing, COD share and RTO rate. These change profit a lot.
  4. Read your real profit See profit, ROAS as Ads Manager shows it, net ROAS and the break-even ROAS you must beat.
  5. Set targets and check campaigns Get a target ROAS for the profit you want, and paste campaigns to see which to scale or fix.

Why Ads Manager ROAS is not profit

  • It counts orders that later return (RTO), so revenue is too high.
  • It ignores product cost, shipping, fees and GST on ads.
  • Compare your ROAS with the break-even ROAS shown here, not with a general “good ROAS”.

Improve profit

  • Cut RTO: confirm COD orders on WhatsApp, offer small prepaid discounts, and check addresses.
  • Raise order value with bundles and free-shipping thresholds.
  • Move budget from “fix” campaigns to “scale” ones, step by step.

About GST on ads

  • Google Ads in India is invoiced by Google India with 18% GST. Check your invoice for other platforms.
  • If you are GST registered and add your GSTIN, you can usually claim this as input tax credit; ask your CA.
  • Enter order value before GST so GST you collect from customers does not look like profit.

Questions about this tool

What is a good ROAS?

It depends on your margins and costs. Any ROAS above your break-even ROAS makes a profit. This tool calculates your break-even from your own numbers.

What is RTO and why does it matter?

Return to origin: a COD order the customer refuses or cannot receive. You pay shipping both ways and get no revenue, so a high RTO rate can wipe out profit.

What is POAS?

Profit on ad spend: profit before ads divided by ad cost. Above 1 means the ads paid for themselves and left profit.

Should I include GST on ad spend?

Yes, unless you claim it back as input tax credit. Tick the box if you do.
