About this tool
The CTR Calculator divides clicks by impressions to give click-through rate, and runs the formula backward: enter a CTR and an impression count to see the clicks it should produce, or a CTR and a click goal to see how many impressions you need to buy. It is for advertisers reading a campaign report, for email and SEO teams who measure the same ratio under different names, and for planners who need to turn a reach estimate into a traffic estimate. If you add the spend, the page also shows CPM and CPC and how the cost per click would change at other click-through rates. A benchmark table lists rough, clearly approximate CTR ranges by channel and marks whether your rate falls below, within, or above each one.
How it works
CTR = clicks ÷ impressions, shown as a percentage. Solving for clicks gives clicks = impressions × CTR, and solving for impressions gives impressions = clicks ÷ CTR. With spend entered, CPM = spend ÷ impressions × 1,000 and CPC = spend ÷ clicks, and because CPC = CPM ÷ (1,000 × CTR) the sensitivity table can show the cost per click your spend would produce at each CTR. The benchmark ranges are broad industry averages compiled from published platform studies; they vary by industry, country, device, and year, and are labelled approximate for that reason.
Frequently asked questions
What is a good click-through rate?
It depends entirely on the channel. A 2% CTR is strong for a social feed ad, ordinary for a search ad, and exceptional for a display banner, where 0.1% to 0.5% is typical. Compare your CTR against the same channel, the same placement, and ideally your own history; a rise from 0.8% to 1.2% on the same campaign says more than any cross-industry average.
Does a higher CTR always mean a better ad?
It means a more clickable ad, which is not the same thing. Clickbait creative can lift CTR while attracting visitors who bounce and never convert, so cost per acquisition gets worse. Read CTR alongside conversion rate: the ideal change raises both, or raises CTR without lowering the conversion rate.
How do impressions and clicks get counted?
Platforms differ. Some count an impression when the ad is served, others only when it is viewable, and social networks distinguish all clicks (including likes and expands) from link clicks. Email CTR is usually clicks divided by delivered messages, while click-to-open rate divides by opens. Only compare CTRs measured the same way.
How does CTR affect what I pay per click?
On impression-priced inventory it sets your CPC directly: CPC = CPM ÷ (1,000 × CTR). At a 10.00 CPM, a 1% CTR gives 10 clicks per thousand impressions, so each click costs 1.00; at 2% it costs 0.50. Search platforms also fold expected CTR into their quality or relevance scores, so a higher CTR tends to lower the bid needed to win the same position.
