About the Ad Metrics Calculator (CTR, CPC, ROAS)
Paste in what a campaign spent and what it produced to get the standard paid-media ratios: click-through rate, cost per click, cost per thousand impressions, cost per acquisition, conversion rate, return on ad spend and ROI.
How to use it
- Enter the ad spend, impressions, clicks, conversions and the revenue they generated.
- Leave out anything you do not have; the matching ratio shows a dash.
- Compare the results against your targets or previous campaigns.
Frequently asked questions
What is a good ROAS?
It depends on your margins. ROAS above your break-even point (1 ÷ profit margin) is profitable; a 30% margin needs a ROAS above about 3.3 just to break even on ad cost.
What is the difference between ROAS and ROI?
ROAS = revenue ÷ ad spend. ROI = (revenue − spend) ÷ spend. A ROAS of 3 equals an ROI of 200% before other costs.
