Click-Through Rate (CTR) Calculator
Works click-through rate, which measures interest rather than results.
Result
More clicks are only better if they convert. A high CTR from a vague headline that attracts the wrong people raises cost without raising booked jobs.

Clicks divided by impressions, expressed as a percentage. It measures how often people who saw something acted on it, which makes it a creative and targeting signal rather than a performance one, since a click costs money and produces nothing by itself.
What moves the number
- Creative and message relevance to the audience.
- Audience targeting precision.
- Placement and position.
- Frequency, which degrades rate over time.
Where this one goes wrong
A high click-through rate with poor conversion is worse than a lower rate that converts, because the clicks cost money and the visitors were not the right people, which happens when creative promises something the page does not deliver. Read rate and conversion together. Frequency is the other factor: the same audience shown the same creative repeatedly clicks less over time, so a declining rate is frequently fatigue rather than a worsening message.
Before you quote
- Read click-through rate alongside conversion rate.
- Check frequency before concluding creative has stopped working.
- Make sure the creative's promise matches the landing page.
Questions
About this calculator
Is a high click-through rate good?
Only with conversion behind it. A high rate with poor conversion is worse than a lower rate that converts, because the clicks cost money and the visitors were the wrong people, usually because the creative promised what the page did not deliver.
Why is my click-through rate falling?
Frequency, most often. The same audience shown the same creative repeatedly clicks less, so a declining rate is frequently fatigue rather than a worse message. Checking frequency before rewriting the creative saves a lot of wasted work.
What is a good click-through rate?
It varies so much by channel, placement, industry and intent that a general figure is not useful. Your own rate over time on the same placement is the comparison that means something, and the trend matters more than the level.
The formula
CTR = clicks ÷ impressions × 100

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Impressions | 84,000 |
| Clicks | 2,520 |
| Target CTR | 4% |
| Average cost per click | $3.2 |
What comes out
| Result | Value |
|---|---|
| Click-through rate main result | 3.00% |
| Extra clicks at your target | 840 |
| Extra cost for those clicks | $2,688 |
| Impressions per click | 33 |
Your CTR is 3.00%, one click per 33 impressions. Reaching 4% would bring 840 more clicks from the same impressions.
How sensitive the answer is
Holding everything else steady and changing only average cost per click, this is what happens to click-through rate. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Average cost per click ($) | Click-through rate |
|---|---|
| $1.6 | 3.00% |
| $2.4 | 3.00% |
| $3.2 example above | 3.00% |
| $4.8 | 3.00% |
| $6.4 | 3.00% |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.

Attribution is the weak link
Return and cost-per-lead figures depend on knowing which enquiries came from which source, and most home-services businesses do not track that reliably. If the source data is guesswork, so is the return.
