> The CTR calculator works out the click-through rate of an ad, email or search result – clicks divided by impressions – and the effective cost per click and cost per thousand impressions if you enter the spend.

## Inputs

- Impressions
- Clicks
- Amount spent

## Results

- Click-through rate
- Cost per click
- Cost per thousand impressions

## Formula

```
CTR = clicks ÷ impressions × 100
CPC = spend ÷ clicks; CPM = spend ÷ impressions × 1,000
```

## Explanation

Click-through rate shows how compelling your ad or listing is to the people who see it. A higher CTR usually lowers your cost per click on platforms like Google Ads because it improves the quality score.

### How to use the CTR Calculator – Click-Through Rate

- **Impressions**
- **Clicks**
- **Amount spent**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the number of impressions and clicks, and optionally the amount spent.

### Tips

- Use figures for the same period (a month, a quarter or a year) for every input so ratios compare like with like.
- Track the metric over time – the trend usually tells you more than a single value.
- Compare your result with industry benchmarks, which vary a lot between sectors.
- Treat the result as a starting point for a decision, then check the assumptions behind each input.

### Common mistakes to avoid

- Mixing monthly and yearly numbers in the same calculation.
- Using revenue where the formula needs profit (or the other way round).
- Forgetting hidden costs such as taxes, fees, overheads or your own time.

### What each result means

- **Click-through rate** = [Clicks]÷[Impressions]×100
- **Cost per click** = [Amount spent]÷max([Clicks], 0.000001)
- **Cost per thousand impressions** = [Amount spent]÷[Impressions]×1000

### Example values

How the main result changes when **Impressions** changes and everything else stays at the example values above:

## Worked example

Inputs — Impressions: 50,000; Clicks: 900; Amount spent: $450.

Results — **Click-through rate = 1.8 %**; Cost per click = $0.50; Cost per thousand impressions = $9.00.
