CTR & Ad Metrics Calculator

Calculate the core performance metrics for any ad campaign or search listing from a few raw numbers. Enter impressions, clicks, conversions, ad spend and revenue, and the tool instantly computes click through rate, conversion rate, cost per click, cost per acquisition, and return on ad spend. These are the numbers that tell you whether a campaign is working: a low click through rate points to weak creative or targeting, a high cost per acquisition eats your margin, and return on ad spend below your break even means you are losing money on every sale. Everything recalculates as you type so you can model scenarios quickly, such as what a small lift in conversion rate does to your cost per acquisition. Use it for Google Ads, Meta, or organic search from Search Console. All math runs locally in your browser with nothing uploaded.
