CTR Calculator

What does this calculator do?

The CTR Calculator has three modes behind one "Mode" switch:

• Basic — enter clicks and impressions, get the click-through rate, the non-click rate, and a plain-language performance rating.
• Reverse — enter a target CTR and your impression count, get the exact number of clicks you need to hit it.
• Compare — paste in several campaigns at once and see each one's CTR side by side, plus which one wins.

The core formula (used everywhere):

CTR = (Clicks ÷ Impressions) × 100

Basic mode example: 250 clicks on 10,000 impressions is 250 ÷ 10000 × 100 = 2.50% CTR, a 97.50% non-click rate, and a "Good" rating.

Reverse mode example: to hit a 2.5% CTR on 333 impressions you need ⌈2.5% × 333⌉ = 9 clicks (rounded up, since clicks are whole numbers) — which actually lands at a 2.703% CTR, slightly above target because 9 is the smallest whole number that clears it.

Compare mode example: paste Search Ads | 317 | 10000, Email | 262 | 10000, and Display | 46 | 10000 and the table shows 3.17%, 2.62%, and 0.46% CTR respectively, with Search Ads flagged as the best performer.

How to use it

1. Pick a Mode at the top.
2. Basic: enter Clicks and Impressions.
3. Reverse: enter your Target CTR (%) and Impressions.
4. Compare: paste one campaign per line into Campaigns, in the format Name | Clicks | Impressions — the same format works if you paste rows out of a spreadsheet.

The result updates as you type. Copy or download the table as CSV from any mode.

What counts as a "good" CTR?

There's no single universal number — it depends heavily on the channel. As a rough reference, published averages run around 3.17% for search ads, 2.62% for email, and 0.46% for display ads, and a CTR above 5% is generally considered excellent across most channels. This tool's rating band (Below Average / Average / Good / Excellent) is a general-purpose scale built around that same ">5% is excellent" benchmark — treat it as a sanity check, not a precise verdict for your specific channel or industry.

Why does Reverse mode's resulting CTR not exactly match my target?

Clicks are whole numbers, but the exact click count for an arbitrary target CTR usually isn't. The tool rounds up to the nearest whole click (so you're guaranteed to meet or beat your target, never fall short), which means the resulting CTR is often a hair above what you asked for.
