Free Heart Rate Zone Calculator Online

Want to train at the right intensity? Our free Heart Rate Zone Calculator maps out your personal training zones the moment you enter your age. As a fast and reliable heart rate zone calculator, it estimates your maximum heart rate and breaks it into the five standard training zonesโ€”each with its own beats-per-minute rangeโ€”so you know exactly what to aim for during a workout.

But it does more than one number. Enter a known max heart rate instead of the age estimate for accuracy, add your resting heart rate to use the more personalised Karvonen method, and read a clear explanation of what each zone is forโ€”from easy recovery to high-intensity effort. Whether you run, cycle, or train, your zones are all in one place.

Simply enter your age to see your zones instantly. No sign-up, no downloads, no limitsโ€”just clear results whenever you need them. Learn more in the FAQ or About pages.
