FAQs
Can a good ROAS still produce a loss?
ROAS compares attributed sales with ad spend. Product costs, fulfilment, returns and other expenses can still leave a loss. Review the margin and break-even figures alongside the ratio.
Which inputs do I need for ROAS, ACOS & Break-Even Ad Spend Calculator?
Use Total Ad Spend (₹); Ad-Attributed Revenue / Sales (₹); Total Store Sales (Ad + Organic for TACOS) (₹); Product Profit Margin Before Ads (%). The built-in examples show how those fields fit together.
What should I check before using this result?
Ensure Ad Spend and Ad Sales use consistent tax-exclusive or tax-inclusive bases. Check the assumptions and output against your intended task before relying on the result.
