Calculate your maximum heart rate using multiple scientific formulas
Traditional: 220 - age
Tanaka: 208 - (0.7 × age)
Gulati (male): 207 - (0.7 × age)
Maximum heart rate (MHR) is the highest number of times your heart can safely beat in one minute during maximum physical exertion. It's used to calculate target heart rate zones for training and exercise prescription.
While formulas provide estimates, your true MHR can only be determined through a maximal exercise test. Individual variation of 10-15 bpm from predicted values is normal and depends on genetics, fitness level, and other factors.
The most widely known formula. Simple but may overestimate MHR for older adults and underestimate for younger people.
Based on a meta-analysis of 351 studies. More accurate across age groups, especially for older adults.
Developed specifically for women based on research showing women have different MHR patterns than men.
Very light activity. Used for warm-up, cool-down, and active recovery.
Light activity. Builds aerobic base and improves fat metabolism. You can maintain a conversation.
Moderate activity. Improves cardiovascular fitness and endurance. Conversation becomes difficult.
Hard activity. Increases lactate threshold and performance. Only short phrases possible.
Maximum effort. For short intervals only. Develops speed and power. No conversation possible.
Formulas provide estimates that may vary by 10-15 bpm from your true MHR. For precise measurement, a graded exercise test with medical supervision is recommended.
Yes, but it requires maximum effort. Most people rarely reach true MHR during regular exercise. Consistently training at maximum HR is not recommended without medical clearance.
MHR is primarily determined by age and genetics, not fitness level. However, well-trained athletes may be able to reach and sustain higher percentages of their MHR during exercise.
