CTR Calculator
CTR, or click-through rate, is the share of impressions that result in a click, expressed as a percentage. It is one of the most useful diagnostic metrics in paid media because it isolates how compelling your ad is to the people who see it, independent of what happens after the click. This free CTR calculator returns your click-through rate from clicks and impressions in one step, and it requires no email.

CTR earns its keep as a triage tool. A low CTR points upstream to creative, targeting, or offer, while a healthy CTR paired with weak results points downstream to the landing page or conversion path. Reading it correctly tells you where to spend your next hour of optimization.
Use it to compare ad variants, monitor creative fatigue over time, or benchmark a placement against the range that is normal for its channel.
How it works
CTR equals clicks divided by impressions, multiplied by 100 to express the result as a percentage. It answers a single question: of everyone who saw the ad, what share clicked it.
Because it is a ratio, CTR is comparable across campaigns of very different sizes. A small test and a large flight can be judged on the same scale, which is what makes it a reliable creative signal.
Worked example
Suppose an ad earns 150 clicks from 10,000 impressions. Divide 150 by 10,000 to get 0.015, then multiply by 100 for a CTR of 1.5%.
That 1.5% means 15 of every 1,000 people who saw the ad clicked it. Comparing this number across creative variants tells you which message and visual the audience responds to.
What is a good CTR?
A good CTR varies more by creative and placement than by channel, so always benchmark against the relevant inventory. Prospecting CTR under 0.5% usually indicates a mismatch between audience and message: either the targeting is reaching the wrong people or the creative is not speaking to them. Retargeting CTR under 2% suggests the creative is not resurfacing the right buying moment for people who already know the brand.
Search inventory typically posts higher CTRs than social or display because intent is explicit; someone querying a product is primed to click. Social prospecting runs lower because you are interrupting a feed, and display lower still because banner blindness is real. Comparing a display CTR to a search CTR will always flatter search and tell you nothing useful.
Use CTR as a diagnostic, not a goal. Low CTR isolates a creative, targeting, or offer problem before you waste budget downstream. High CTR with weak conversion isolates a landing page or offer-fit problem. Watch the trend, not the point-in-time value: a CTR that drifts down over weeks is the clearest early signal of creative fatigue.

Frequently asked questions
What is a good CTR?
A good CTR depends on placement and creative more than channel. Prospecting CTR under 0.5% usually signals an audience or message mismatch, and retargeting CTR under 2% suggests the creative is not hitting the right buying moment. Search inventory runs higher than social or display because intent is explicit, so always compare to the relevant placement.
How do you calculate CTR?
CTR equals clicks divided by impressions, multiplied by 100. For example, 150 clicks from 10,000 impressions is (150 / 10,000) x 100, or a 1.5% click-through rate. It tells you the share of people who saw your ad and clicked it.
What does a low CTR tell me?
A low CTR isolates an upstream problem before the click: weak creative, mistargeted audiences, or a poor offer. It does not, on its own, indicate a landing page issue, because nobody who fails to click ever reaches the page. Use low CTR to fix creative, targeting, and offer first.
Why does CTR differ between search, social, and display?
Search CTR is highest because the user has explicit intent and is actively looking for a solution. Social prospecting is lower because the ad interrupts a feed, and display is lower still due to banner blindness. Comparing CTR across these placements is misleading; benchmark each against its own inventory.
Can a high CTR be a problem?
It can, if clicks do not convert. A high CTR paired with weak conversion usually points to a landing page or offer-fit problem, or to clickbait creative that attracts curiosity rather than intent. Pair CTR with conversion rate to tell a strong ad from a misleading one.
