RMR and BMR Calculator

There are two methods of calculating how many calories you burn in a day, or how many calories you need to eat to sustain your current weight. These methods are called RMR (resting metabolic rate) and BMR (basal metabolic rate). We've provided calculators for both methods.

Cardiovasculor / Target Heart Rate Calculator

Your target heart rate is a useful way of pacing yourself when you exercise, to make sure your level of activity is not too high or too low. You also can use your target heart rate to evaluate your initial fitness level and your progress over time. To do this, you'll need to measure your heart rate from time to time as you exercise. Our calculator will provide you with the appropriate target heart rate range.

Note: This calculator is not intended for children or the very elderly.
