Calculate click-through rate
Click-through rate is the percentage of people who click after seeing something, and it measures how compelling your ads or listings are. This calculator computes CTR from clicks and impressions, plus related CPC, CPM and CPA metrics.
Why CTR measures appeal
CTR is clicks divided by impressions, so it captures how effectively something turns a view into a click, whether an ad, a search listing, or an email. A low CTR means people see but do not act, pointing at weak creative, poor targeting, or an unappealing offer; a high CTR means the message is landing. Because it isolates the appeal of what is shown from later steps, CTR is where you diagnose and improve the top of the funnel. Seeing it alongside CPC, CPM and CPA connects appeal to cost and result.
A planning estimate
This is an estimate for planning from the figures you enter, not financial or business advice. Real outcomes depend on factors beyond any single calculation, so treat the result as a guide. It runs entirely in your browser, so your figures are never uploaded and stay on your own machine, which matters for business numbers you would not want to share.

Frequently Asked Questions
What is click-through rate?
The percentage of people who click after seeing something, clicks divided by impressions. It measures how compelling an ad, listing or email is.
Why does CTR matter?
Because it isolates the appeal of what is shown. A low CTR points at weak creative, targeting or offer; a high one means the message is landing.
How does CTR relate to other metrics?
It sits at the top of the funnel: CTR drives clicks, which combine with conversion rate for CPA, and with spend for CPC and CPM. The calculator shows these together.
What is a good CTR?
It varies widely by channel and context, so compare against benchmarks for your specific channel rather than an absolute number.
