How to use the acos & roas calculator

  1. Copy spend and attributed sales for the same dates from your ads dashboard.
  2. Add your total sales for TACoS.
  3. Enter your margin before ads: ACoS below it means the ads pay for themselves.

How it's worked out

ACoS = ad spend ÷ ad sales. ROAS = ad sales ÷ ad spend. TACoS = ad spend ÷ all sales. Ads break even when ACoS equals your margin before ads.

Questions sellers ask

What is a good ROAS for Meesho or Flipkart ads?

Any ROAS above 1 ÷ your margin makes money. At a 25% margin that is a ROAS of 4 (ACoS 25%).
