CTR Calculator: Click-Through Rate (Free)
Calculate click-through rate (CTR) as a percentage: divide clicks by impressions and multiply by 100.
CTR (Click-Through Rate) is the share of impressions that become clicks. Formula: CTR = (Clicks ÷ Impressions) × 100. Example: 2,500 clicks ÷ 100,000 impressions = 2.50% CTR.

Worked examples
Plug in sample numbers to see how the CTR Calculator formula works in practice.
Social ad set
- Clicks
- 3,000
- Impressions
- 150,000
CTR = (3,000 ÷ 150,000) × 100 = 2.0%
Display placement
- Clicks
- 400
- Impressions
- 200,000
CTR = (400 ÷ 200,000) × 100 = 0.20%
Display CTRs are often much lower than search—compare like with like.
Benchmarks
Directional ranges—always prefer your own baselines and unit economics.
| Context | Guidance |
|---|---|
| Search ads | Often higher CTR than display (varies by query) |
| Social feed | Roughly 0.5–2% is common; creative dependent |
| Display | Often under 0.5% |
| How to judge “good” | Beat your own account baseline for that placement |
Common mistakes
- Comparing search CTR to display CTR — Baselines differ by format. Segment reports.
- Assuming high CTR equals profit — Connect CTR to landing-page conversion rate, CPA, and ROAS.
- Ignoring frequency fatigue — CTR often falls as frequency rises—refresh creative.
