This maximum rate is based on the person's age. An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 50 years = 170 beats per minute (bpm).
The maximum heart rate is, on average, the highest your pulse rate can get based on your age. To calculate your predicted maximum heart rate, use this formula: 220 - Your Age = Predicted Maximum Heart Rate.Example: a 40-year-old's predicted maximum heart rate is 180.he maximum heart rate is, on average, the highest your pulse rate can get based on your age. To calculate your predicted maximum heart rate, use this formula: 220 - Your Age = Predicted Maximum Heart Rate.
