Reply rate and acceptance rate calculator
Enter five counts from your campaign and the calculator returns the acceptance rate, the reply rate, the meeting rate and replies to meetings, each with a 95% range. It counts people, not messages: acceptance per person invited, reply rate per person messaged.

Calculate your rates
| Rate | Value | 95% range | Counted as |
|---|---|---|---|
| Acceptance rate | 35.0% (175 of 500) | 30.9% to 39.3% | accepted divided by invited, one invitation per person |
| Reply rate | 33.3% (50 of 150) | 26.3% to 41.2% | replied divided by people messaged after they accepted |
| Meeting rate | 5.3% (8 of 150) | 2.7% to 10.2% | meetings divided by people messaged |
| Replies to meetings | 16.0% (8 of 50) | 8.3% to 28.5% | meetings divided by people who replied |
The range is a Wilson interval at 95%. With a small base the range is wide, so do not read much into a gap of a few points. Nothing you type leaves this page.
The definitions
| Rate | Numerator | Denominator |
|---|---|---|
| Acceptance rate | People whose invitation was accepted | People invited, counted once on the first invitation |
| Reply rate | People who wrote back after the first message | People who received a message after accepting |
| Meeting rate | Meetings booked | People messaged |
| Replies to meetings | Meetings booked | People who replied |
Count each person once. Auto replies and out of office messages are not replies. Give invitations at least 30 days to be accepted before you measure.
A worked example
| Rate | Value | 95% range |
|---|---|---|
| Acceptance | 35.0% (175 of 500) | 30.9% to 39.3% |
| Reply | 33.3% (50 of 150) | 26.3% to 41.2% |
| Meeting | 5.3% (8 of 150) | 2.7% to 10.2% |
| Replies to meetings | 16.0% (8 of 50) | 8.3% to 28.5% |
The range is a Wilson interval at 95%. The 150 messaged leave a wide range: the true reply rate could sit anywhere from 26% to 41%.
For examples measured the same way, with their own bases, read the case studies. The numbers differ by audience and offer, so compare with the study closest to yours.
Limits
- Small bases move a lot. Fewer than 100 people in a denominator leaves a range of more than 10 points.
- Rates differ by audience and offer. A foundry president writing to engineers and a referral network writing to advisors are different markets, so Sellinger's case studies are never averaged.
- Quick replies count. At the referral network 44.8% replied overall, and 33.7% replied with more than a pleasantry, so decide which one you measure.
The tool runs entirely in your browser. Nothing you type is sent to Sellinger or stored, so it needs no account, has no rate limit and costs nothing to run.
