Frequently asked questions

How do you calculate ROI?
ROI = (amount returned − amount invested) ÷ amount invested × 100. For example, earning $2,500 from $1,000 of ad spend is a net return of $1,500 and a 150% ROI.
What is the difference between ROI and ROAS?
ROAS (return on ad spend) is revenue divided by ad spend, expressed as a ratio like 2.5x. ROI is net profit as a percentage of cost. A 2.5x ROAS is the same as a 150% ROI. This tool shows both — the return ratio is your ROAS.
What is a good ROI?
Any positive ROI means you earned more than you spent, but a "good" ROI depends on your margins and goals. For paid advertising, your ROI needs to clear your break-even point — which depends on your profit margin — to be truly profitable.
Can I use this for ad campaigns?
Yes. Enter your total ad spend as the amount invested and the revenue it generated as the amount returned to see your campaign ROI and return ratio (ROAS).
