How to use this calculator
Four steps, and nothing to submit.
Choose what you are solving for. CTR if you already have clicks and impressions. Clicks if you have a rate and a volume of impressions. Impressions if you have a click target and a rate you think you can hold.
Paste the two figures you have. Straight out of the platform report. Commas, percent signs and currency symbols are stripped for you.
Add spend or conversions if you have them. They are optional, and they are what turn a rate into a cost. Without them you get a percentage; with them you get what that percentage is costing you.
Compare against the right benchmark. Not the account average, and not a figure from another channel. The section below gives one current search benchmark with its source and its date attached.
If the result looks impossible, check if the two figures came from the same date range and the same campaign. Mismatched ranges are the most common cause of a CTR that will not reconcile.
What CTR means
Click-through rate is the share of people who clicked after being shown something. Divide clicks by impressions, multiply by a hundred, and you have it.
It is the most portable metric in marketing, because almost everything gets shown and some of it gets clicked. Search ads, display banners, email campaigns, organic listings, social posts - all of them have a CTR, and none of their CTRs mean the same thing.
That last point is where most CTR analysis goes wrong. A 6% search CTR and a 6% display CTR describe completely different outcomes, because someone typing a query has already declared intent and someone scrolling past a banner has not. Read CTR as a measure of how well a message matched the moment it appeared in, not as a score.
The CTR formula
The multiplication by 100 only converts the fraction to a percentage. The whole calculation is one division.
It rearranges two ways, and both are more useful than the forward version once a campaign is being planned rather than reported on.
Clicks a CTR target implies: clicks = impressions × (CTR ÷ 100). At a 6.64% CTR, 250,000 impressions produce about 16,600 clicks.
Impressions a click target needs: impressions = clicks ÷ (CTR ÷ 100). To get 20,000 clicks at a 6.64% CTR you need roughly 301,200 impressions.
That second one is the number media plans are actually built from. You rarely start with clicks and impressions in hand - you start with a click target and a rate you think you can hold.
Where to find your CTR, and what each platform is counting
Every platform reports a click-through rate. They are not all counting the same thing, and two of these differences are big enough to make a comparison meaningless.
The Meta one catches people constantly. A campaign can look like it doubled its click-through rate when the report was simply reading the other column. Decide which definition you are using, write it down, and use the same one every month.
What a good CTR looks like
There is no single good CTR, and the number moves more by channel than by campaign quality.
The most current benchmark available for paid search:
Read the spread, not the midpoint. The gap between the best and worst industries is more than double, and none of that gap is skill - it is how much intent sits behind the query.
Be careful which benchmark you are being shown. The figure most often quoted for search CTR is 3.17%, and it comes from data collected between August 2017 and January 2018. It is nearly a decade old and roughly half the current median, yet it is still repeated as though it were current. If you are being compared against it, you are being compared against a different internet.
Other channels sit on entirely different scales - display is a fraction of search, email sits between them, and organic listings vary enormously by position. Quoting a number for each of those needs a current source for each of them; this page cites what it can stand behind rather than filling a table.
Organic CTR is a different measurement
The same formula runs on organic search, but almost nothing about how to read it carries over.
In Search Console, an impression is your listing being shown for a query and a click is somebody choosing it over everything else on the page. Position therefore drives the rate far harder than the wording does. A listing near the top of the page collects a large share of the clicks and every position below it collects dramatically less, which is why a page can improve its copy, hold its position and see no change at all.
Two things make organic rates harder to compare than paid ones. Results pages now carry AI summaries, product panels and answer boxes that absorb clicks before any listing gets one, so the same position earns fewer clicks than it did a few years ago - the AI visibility checker measures that shift directly. And the rate varies by intent: a query where the answer fits in the snippet will always click through less than one where it does not.
Used the other way round, the calculator estimates traffic. Take the monthly searches for a term, put them in as impressions, put in the rate you expect to hold at your position, and it returns the clicks that ranking is worth. That is the calculation behind most keyword prioritisation, and it is worth doing before writing rather than after.
How to improve CTR
Match the message to the query, not to the brand. The single largest lever in search. An ad that repeats the words someone typed will beat a better-written ad that does not.
Tighten the targeting before rewriting the creative. A low CTR often means the right ad is being shown to the wrong people. Narrowing the audience raises CTR even when nothing about the message changes - though it usually raises CPM at the same time, which is the trade to watch.
Use everything the format gives you. Sitelinks, callouts, images, structured snippets. They cost nothing, they enlarge the ad, and a bigger ad takes a larger share of the screen.
Test one variable at a time. Headline or offer or image - not all three. Three changes at once produce a number you cannot learn anything from.
Cut what has stopped working. Rising frequency with falling CTR is fatigue, and the fix is a genuinely different asset rather than a recoloured one.
The counterweight matters here more than on most metrics. CTR is easy to raise and easy to raise pointlessly. A more provocative headline will lift clicks and can lower conversion rate at the same time, leaving you with more traffic, the same customers and a bigger bill. Judge it beside cost per acquisition, which is why the calculator returns both.
Common mistakes
Comparing CTR across channels. Search and display CTRs are not the same measurement. Placing them side by side looks like analysis and tells you nothing.
Chasing CTR on its own. It is an input to cost, not an outcome. A campaign can improve its CTR and lose money.
Using a benchmark without checking its date. The most-quoted search CTR figure is from 2017-18 data.
Reading a rate off too small a sample. A few hundred impressions is noise. Wait for volume before concluding anything.
Forgetting that CTR feeds Quality Score. In Google Ads, expected click-through rate is one of the components of Quality Score, so CTR affects what you pay per click as well as how many clicks you get.
Averaging CTR across a whole account. The account average is a blend of very different campaigns and usually describes none of them. Compare like with like - you cannot segment CTR by campaign source without tagged links, which is what the UTM builder is for.

FAQ
Frequently Asked Questions
How do you calculate CTR?
Divide the number of clicks by the number of impressions, then multiply by 100 to turn the fraction into a percentage. An ad served 40,000 times that collected 2,800 clicks has a CTR of 7.00%. Both figures appear in the same reporting view on every ad platform, so the arithmetic itself is trivial - the judgement is in what you compare it against.
What is a good CTR?
It depends almost entirely on the channel. Across US search campaigns the median sits near 6.6%, with industries ranging from roughly 5.5% to nearly 13%. Display runs at a small fraction of that, because nobody scrolling past a banner asked to see it. Compare your rate against your own channel and your own previous months.
Can CTR be higher than 100%?
No. Every click has to come from an impression, so clicks can never exceed the times something was shown. A figure above 100% means the two numbers came from different date ranges, different campaigns, or a report counting clicks and impressions on different bases. It is a data problem, not a performance one.
What is the difference between CTR and conversion rate?
CTR measures how many people clicked after seeing something. Conversion rate measures how many of those people then did what you wanted. They move independently, and often in opposite directions - a headline that overpromises will lift the first and damage the second, which is why judging either one alone is misleading.
Does CTR affect what I pay for ads?
In Google Ads, yes. Expected click-through rate is one of the components of Quality Score, and Quality Score influences both your ad rank and your cost per click. A well-matched ad can therefore end up cheaper per click than a poorly matched one bidding the same amount.
How many impressions do I need for a reliable CTR?
Enough that a handful of clicks either way stops moving the number much. At a few hundred impressions, one extra click can shift the rate by a full percentage point. Tens of thousands of impressions give a figure worth acting on; anything smaller is a direction at best.
Is a low CTR always a problem?
Not necessarily. Broad awareness campaigns and prospecting audiences produce low rates by design, because they are shown to people who have not asked for anything. What matters is whether the rate is low for that channel and that audience - and whether the traffic it does bring converts.
What is a good CTR in Search Console?
Ask instead what is good for that position. Organic click-through rate is dominated by where the listing sits and what else the results page is showing, so the same page can carry very different rates on two queries without anything being wrong. Compare a query against its own history, and against other queries where you hold a similar position.
What is CTOR, and is it the same as email CTR?
No, and the gap between them is large. Click-to-open rate divides clicks by opens rather than by emails delivered, so it describes how well the message worked on people who actually saw it, while the standard rate blends that with how well the subject line performed. Quoting one and labelling it the other is the most common reporting error in email.
Why do my two CTR numbers not match?
Usually because the denominators differ. Different date ranges, one figure filtered to a campaign type and the other not, or a platform offering two click definitions and the report picking the wider one. Before assuming performance changed, confirm both numbers were built from the same rows.
