Email CTR Calculator
Calculate Email CTR metrics for ecommerce, SaaS, marketing, and operations.
This email CTR calculator finds click-through rate (clicks relative to emails delivered) and click-to-open rate (clicks relative to emails opened) - two related metrics that reveal different things about an email campaign's effectiveness.
Enter your clicks, opens, and delivered count, and the calculator returns both rates.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 10,000 delivered, 2,500 opens, 300 clicks | CTR 3% · CTOR 12% | CTR = (300 ÷ 10,000) × 100 = 3%. CTOR = (300 ÷ 2,500) × 100 = 12%. |
| 8,000 delivered, 1,600 opens, 80 clicks | CTR 1% · CTOR 5% | CTR = (80 ÷ 8,000) × 100 = 1%. CTOR = (80 ÷ 1,600) × 100 = 5% - a low CTOR here suggests the email content itself isn't compelling enough, even though it was opened. |
CTR vs. Click-to-Open Rate
Click-through rate (CTR) = (clicks / delivered) x 100, measuring overall campaign performance from send to click. Click-to-open rate (CTOR) = (clicks / opens) x 100, isolating how compelling the email content was for people who actually opened it, independent of subject line performance.
Why Both Metrics Matter Together
A low CTR with a high CTOR suggests the subject line or send timing needs improvement (few people are opening), while a high CTR with a low CTOR suggests the email content or call-to-action needs work (people are opening but not clicking) - looking at both metrics together helps diagnose where a campaign is underperforming.

Frequently Asked Questions
How do you calculate email click-through rate?
Divide the number of clicks by the number of emails delivered, then multiply by 100: CTR = (clicks / delivered) x 100.
What is click-to-open rate?
It's clicks divided by opens (not total delivered), showing how effective the email content was at generating clicks among people who actually opened the email.
Why is my CTR low even though my open rate is high?
This pattern suggests the subject line is working well, but the email content, offer, or call-to-action isn't compelling enough to drive clicks - reviewing click-to-open rate specifically can help confirm this diagnosis.

What does the Email CTR Calculator calculate?
Calculate Email CTR metrics for ecommerce, SaaS, marketing, and operations. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this email ctr use?
The formula is: CTR = (Clicks ÷ Delivered) × 100; CTOR = (Clicks ÷ Opens) × 100. Distinguishing CTR from click-to-open rate became standard email marketing analysis in the 2000s as marketers realized the two metrics diagnose different problems: a weak CTR with strong CTOR points to a subject line or deliverability issue, while a strong CTR-relative-to-opens but weak CTOR points to unengaging email content - a diagnostic distinction still central to A/B testing methodology in email marketing today.
