About ROAS Calculator
The one formula
ROAS (return on ad spend) is ad revenue ÷ ad spend. The calculator prints it as a multiple such as 5.00x, meaning each rupee of advertising produced five rupees of revenue.
Example
Revenue Rs. 50,000 from Rs. 10,000 spend gives 5.00x.
A high ROAS is not always profit
ROAS uses revenue, not profit. Whether 5x is good depends on your gross margin. The break-even ROAS is 1 ÷ gross margin: at a 40% margin you need at least 2.5x to cover product cost and ad spend, and anything above is profit before other overheads. At a 20% margin you need 5x just to break even.
How to use it
- Calculate it per campaign or ad set, not only account-wide, since averages can hide losers.
- Use the same attribution window for revenue and spend, because delayed purchases skew short-window figures.
- Zero spend gives an undefined result.
Pair it with the profit margin calculator to find your own break-even ROAS.
Frequently Asked Questions
ROAS is simply revenue ÷ ad spend, expressed as a multiplier (e.g. 5x). ROI is (return − investment) ÷ investment, expressed as a percentage, and nets out the cost. A 5x ROAS and a 400% ROI describe the same underlying numbers, just presented differently.
The revenue you attribute to the ad spend being measured — typically from your ad platform's conversion tracking or attribution model. This calculator doesn't do attribution itself; it just divides whatever revenue figure you enter by spend.
It depends entirely on your margins — a business with 20% profit margin needs a much higher ROAS to be profitable than one with 60% margin. There's no universal 'good' number; compare ROAS against your break-even ROAS (1 ÷ your margin %).
No — this is a pure revenue-to-ad-spend ratio. To know if a campaign is actually profitable, compare ROAS against your break-even ROAS which factors in product cost and other expenses.
