Resting Heart Rate Calculator
Enter your age, sex and resting heart rate to see where you sit against broad adult population norms for age 40 and up.
This is a population benchmark, not a diagnosis. Lower is not automatically better, and higher is not automatically dangerous. Resting heart rate is affected by fitness, stress, sleep, illness, caffeine, dehydration and medication such as beta-blockers. Use trends, not one-off readings.
How the calculator works
The calculator compares your resting heart rate with age- and sex-banded reference values using the 10th, 25th, 50th, 75th and 90th percentile points from the norm table. Percentiles are shown in the normal statistical direction: a lower percentile means a lower resting heart rate than most people, not a worse score.
| Percentile band | Meaning |
|---|---|
| ≤25th percentile | Lower than average — often favourable, especially in active people |
| 25th–75th percentile | Typical range |
| ≥75th percentile | Higher than average — worth watching if it is your usual level |
