Target Heart Rate Calculator

Use this target heart rate calculator to determine your heart rate at the target percentage you desire for your workouts. It will also show you the range of heart rate you should be in to be in the moderate-to-vigorous intensity aerobic fitness zone.
Enter your age:
Level of exercise: % of maximum heart rate
Target heart rate at this level: beats per minute
Recommended target range: to beats per minute
Note: these calculations are based on averages. It is recommended that you exercise within 55 to 85 percent of your maximum heart rate for at least 20 to 30 minutes to get the best results from aerobic exercise.

To see a different result for your age or target percentage, simply change the number and select the "Calculate Your Target Heart Rate" button again.

This calculator uses a simple age-graded estimation of your maximum heart rate and multiplies it by your chosen percentage. For a more customized heart rate percentage, you may wish to use the Karvonen formula which requires you to know your resting heart rate .
