This calculator estimates your maximum heart rate from your age using two widely cited formulas so you can compare them. The classic Fox formula is simply 220 minus your age, which is easy to remember but tends to run high for older adults. The Tanaka formula, 208 minus 0.7 times your age, was derived from a large meta analysis and often gives a more accurate estimate across the adult age range. Enter your age once and both estimates appear together in beats per minute. Maximum heart rate is a population average, so your true maximum can differ by ten beats or more, and only a supervised test measures it precisely. Everything runs locally in your browser. This is general information, not medical advice, so anyone with a heart condition should speak to a doctor before high intensity exercise.
It shows the classic 220 minus age formula alongside the Tanaka formula of 208 minus 0.7 times age, so you can compare the two estimates.
These formulas are population averages, so an individual maximum heart rate can differ by roughly ten beats either way.
The Tanaka formula tends to fit older adults better, so seeing both gives a fuller picture than one number alone.
