About this calculator
A maximum heart rate calculator estimates the highest heart rate you can safely reach during all-out exercise, from your age. The classic estimate is 220 minus your age; the Tanaka formula (208 − 0.7 × age) is more accurate for older adults. These are population averages — individual maximums vary by roughly ±10–12 beats per minute.
Frequently asked questions
Which max heart rate formula is best?
220 − age is the best-known but tends to overestimate for the young and underestimate for older adults. Tanaka (208 − 0.7 × age) fits the population better, which is why both are shown.
How accurate is an age-based estimate?
It is only an average. True maximum heart rate varies by about ±10–12 bpm between individuals of the same age, so a graded exercise test is the only precise way to measure yours.
