CTR Calculator
Click-through rate from clicks and impressions, plus implied click cost.
What is click-through rate?
Click-through rate (CTR) is the percentage of people who click an ad, link, or email after seeing it. It's one of the simplest signals of how compelling a creative is for the audience that saw it. A high CTR means the headline, image, or offer matched what people were looking for; a low CTR usually means the targeting, the message, or both need work. CTR is the entry point to almost every funnel metric — without clicks, there are no visits, no sign-ups, and no conversions to talk about.
How to use this calculator
Enter your raw numbers and the tool returns the rate plus a couple of useful side metrics.
- Enter the total impressions for the campaign or asset.
- Enter the total clicks recorded over the same period.
- Optionally add the average cost per click to see total click cost.
- Compare the result to the channel benchmarks below.
Formula
CTR is a simple ratio of clicks to impressions, expressed as a percentage.
CTR % = ( Clicks ÷ Impressions ) × 100
- Clicks — total interactions with the ad, link, or button.
- Impressions — number of times the ad was rendered or the email was opened.
- CPC — average cost paid per click (optional input for total cost).
Typical CTR by channel
Use these ranges as a sanity check, not a target. Performance varies wildly by industry, audience and creative quality.
| Channel | Low | Average | Good |
|---|---|---|---|
| Paid search (Google, Bing) | 1.5% | 3.2% | 6%+ |
| Display banners | 0.05% | 0.46% | 1%+ |
| Paid social (Meta, TikTok) | 0.5% | 1.2% | 3%+ |
| Email marketing | 1% | 2.5% | 5%+ |
| Video / YouTube ads | 0.3% | 0.8% | 2%+ |

Frequently asked questions
What's a good CTR?
For paid search, anything above 3% is healthy. For display, 0.5% is already good. For social, aim above 1%. Your channel benchmark is the only ceiling that matters.
Why is my CTR so low?
The usual suspects are weak headlines, irrelevant audiences, ad fatigue, and a creative that doesn't match the offer. Test variants of the strongest hook before changing anything else.
Does a high CTR mean the campaign is working?
Not on its own. CTR only tells you the ad got clicked. The conversion rate, cost per acquisition, and ROAS tell you if those clicks turned into business.
How do I improve CTR?
Tighten the headline, lead with the benefit, add numbers and proof, refine the audience, and rotate creatives before they fatigue. Small headline tweaks usually move CTR more than a redesign.
Is CTR the same on email and ads?
The math is identical, but the bases differ: in email, impressions are usually opens or sends; in ads, they are placements. Compare email CTR to email benchmarks only.
Can CTR be over 100%?
Not in standard counting. If you see that, your tool is counting multi-click sessions or counting opens incorrectly. Audit the source data before drawing conclusions.
