How it works
Enter the requested values, check the units, then run the Heart Rate Zones Calculator for a copyable informational estimate.
The tool works by estimating maximum heart rate as 220 minus age and applying five percentage bands. The result is a general estimate that cannot account for every individual factor and does not replace a clinician. Inputs stay in the browser.
Examples
Practical example
Age 40 gives an estimated maximum near 180 bpm before percentage zones.
Method and source
Uses the American Heart Association general guide: estimated maximum heart rate is about 220 minus age; exercise ranges are averages.
