Questions

FAQ

How is ROAS calculated?

ROAS is revenue divided by ad spend. If you spent $1,000 and got $8,730 in revenue, ROAS is 8.73x. The calculator shows ROAS next to the break-even ROAS, so you see not just the ratio but whether the ratio is enough for your margin.

What is break-even ROAS?

The ROAS at which revenue exactly covers the cost of ads at your gross margin: 1 / margin. At a 40% margin it is 2.5x - below that the campaign spends more than the gross profit it brings.

Are the default values based on real numbers?

The defaults are the same ratio we use in our own media plans, just converted to USD. Change every input: budget, CPC, both conversions, average order value and margin.

Does the calculator send my numbers anywhere?

No. All math runs in your browser, the page does not collect or transmit the values you enter.
