Frequently asked questions

What is a good ROAS?

A common rule of thumb is 4:1 (₹4 revenue per ₹1 spent), but the right target depends entirely on your profit margin. A low-margin business needs a much higher ROAS to stay profitable than a high-margin one.

What’s the difference between ROAS and ROI?

ROAS compares revenue to ad spend only. ROI compares profit (revenue minus cost) to the cost, so it factors in that you don’t keep the whole revenue. This tool shows both.

How do I find my break-even ROAS?

Divide 1 by your profit margin. At a 25% margin you need a 4× ROAS just to break even; above that you’re profitable. Enter your margin above and the tool works it out for you.

How do I calculate ROAS?

To calculate ROAS (return on ad spend), divide the revenue an ad campaign generated by what you spent on it. This free ROAS calculator does it instantly — enter your ad revenue and ad spend and it shows ROAS as both a multiple (e.g. 4×) and a percentage.

What is a ROAS calculator used for?

A ROAS calculator measures how much revenue each rupee of advertising returns, so you can judge whether a Google Ads, Facebook or Instagram campaign is profitable. It’s the quickest way to compare campaigns, channels and ad sets on the same return-on-ad-spend basis.

What does a 4x ROAS mean?

A 4× ROAS means you earned ₹4 in revenue for every ₹1 of ad spend — a 400% return on ad spend. Whether that’s profitable depends on your margin, so add your profit margin above to see the break-even ROAS you actually need.

What is the difference between ROAS and ROI?

ROAS (return on ad spend) compares revenue to ad spend only — e.g. 4× means ₹4 revenue per ₹1 spent. ROI factors in profit, comparing (revenue − all costs) to cost. A 4× ROAS can still be unprofitable if your margins are thin, which is why this tool shows both plus a break-even ROAS.

How do I calculate break-even ROAS?

Break-even ROAS is 1 ÷ your profit margin. At a 25% margin you need a 4× ROAS just to cover costs; at 50% you only need 2×. Enter your profit margin above and the calculator shows the break-even ROAS you must beat to make a profit.
