How do I use the ad metrics calculator?
Enter the numbers from your ad platform: impressions, clicks, conversions, spend and revenue. Every metric updates as you type. If you leave a field empty, the metrics that need it show a dash.
What do CTR, CPC and CPM mean?
CTR is the share of impressions that led to a click (clicks ÷ impressions × 100). CPC is what you pay for each click (spend ÷ clicks). CPM is what you pay for every 1,000 impressions (spend ÷ impressions × 1,000).
What do conversion rate and CPA mean?
Conversion rate is the share of clicks that led to a conversion (conversions ÷ clicks × 100). CPA is what you pay for each conversion (spend ÷ conversions). A conversion can be a sale, a sign-up, a form fill or any other action you track.
What is the difference between ROAS and ROI?
ROAS is the revenue you earn for each £1 of ad spend (revenue ÷ spend). A ROAS of 4 means £4 of revenue for every £1 spent. ROI is the profit as a percentage of spend ((revenue – spend) ÷ spend × 100). ROAS ignores other costs, such as product cost and fees. Add those costs to your spend figure to get a truer ROI.
What is a good ROAS?
It depends on your margins. A business with a 50% margin needs a ROAS of 2 to break even on ad spend. A business with a 20% margin needs a ROAS of 5. Work out your break-even ROAS first, then compare your result to it.
Is my data uploaded anywhere?
No. Every calculation runs in your browser. The numbers you enter never leave your device.
How do I track which campaign drove each click?
Add UTM parameters to your ad links with the UTM URL builder. Your analytics tool can then report clicks, conversions and revenue for each campaign.
