Free reply rate calculator for cold email
Enter your campaign numbers to get your reply rate per email and per contact, your positive reply rate and how many positive replies become meetings, compared with 2026 benchmarks.
How the reply rate calculator works
Reply rate per email = replies ÷ emails sent × 100. That is the definition used by Instantly's 2026 Cold Email Benchmark Report, so you can compare like with like.
Reply rate per contact = replies ÷ contacts × 100. It is higher for multi-step sequences, because one contact gets several emails.
Positive reply rate = positive replies ÷ contacts. Reply-to-meeting rate = meetings ÷ positive replies. The calculator runs in your browser, and nothing you type is sent anywhere.
