Maximum Heart Rate Calculator

The simplest formula is 220 minus your age. More accurate formulas include Tanaka (208 - 0.7 x age) for the general population and Gulati (206 - 0.88 x age) for women. The only truly accurate method is a maximal exercise stress test.

The Tanaka formula (208 - 0.7 x age) is generally considered more accurate than the traditional 220 - age formula. For women, the Gulati formula (206 - 0.88 x age) may be more appropriate. Individual variation can be 10-20 bpm.

Yes. Maximum heart rate naturally declines with age at a rate of about 0.7 bpm per year. This is a normal physiological change and does not necessarily indicate reduced fitness. Fitness is better measured by resting heart rate and recovery rate.
