📘 About the Max Heart Rate

Maximum heart rate, often written as HRmax, is the highest heart rate a person is expected to reach during maximal physical effort.

Because maximum heart rate is difficult to determine without a maximal exercise test, age-based equations are commonly used to provide an estimate.

This calculator uses sex-specific equations published from a large dataset of people who completed maximal exercise testing.

The equations estimate maximum heart rate from age and sex only. Your actual maximum heart rate can be different from the calculated value.

🧭 How to use this calculator

What you enter

  • SexSelect male or female.
  • Age (years)Enter your age in completed years.

What you get

  • Estimated Maximum Heart Rate (bpm)
  • Moderate Exercise Lower Range (bpm)
  • Moderate Exercise Upper Range (bpm)
  • Vigorous Exercise Lower Range (bpm)
  • Vigorous Exercise Upper Range (bpm)

💡 Maximum heart rate formula

  • For males: HRmax = 208.609 - (0.716 x age).
  • For females: HRmax = 209.273 - (0.804 x age).
  • Age is entered in completed years.
  • The result is expressed in beats per minute, abbreviated as bpm.

💡 Where the equations came from

  • The sex-specific equations were developed from maximal exercise-test data involving 28,137 participants aged 10 to 80 years.
  • The research included 20,691 males and 7,446 females.
  • The researchers also tested the equations against a separate validation sample.
  • The study found that maximum heart rate decreased with age and that the rate of decline differed between males and females.

💡 Maximum heart rate versus resting heart rate

  • Maximum heart rate is the estimated highest heart rate during maximal exercise.
  • Resting heart rate is measured when you are relaxed and at rest.
  • They are different measurements and should not be confused.
  • The American Heart Association states that a resting heart rate between 60 and 100 bpm is typical for many adults.

💡 Exercise heart rate zones

  • The American Heart Association describes moderate-intensity exercise as approximately 50% to 70% of maximum heart rate.
  • Vigorous-intensity exercise is approximately 70% to 85% of maximum heart rate.
  • These percentages are general guides rather than exact personal limits.
  • The calculator displays these ranges using the estimated maximum heart rate.

💡 Why your actual maximum heart rate may differ

  • Age-based equations provide population-level estimates rather than an exact measurement for one person.
  • Individual maximum heart rate can differ substantially from an age-predicted value.
  • Fitness status, health conditions, medications and other factors can influence heart rate responses.
  • Some medications can lower maximum heart rate and change appropriate exercise heart-rate zones.

💡 220 minus age formula

  • The commonly known 220 minus age equation is another traditional estimate of maximum heart rate.
  • The American Heart Association continues to present 220 minus age as a general age-based estimate.
  • Research has also evaluated alternative equations, including sex-specific equations and the Tanaka equation.
  • Different equations can produce different estimates, so the result should be viewed as an approximation rather than an exact personal maximum.

💡 Important safety information

  • Do not deliberately push yourself to your estimated maximum heart rate simply to test the calculator.
  • If you have a heart condition or take medication that affects heart rate, ask your healthcare professional about appropriate exercise intensity.
  • If you experience chest pain, fainting, severe shortness of breath or other concerning symptoms during exercise, stop exercising and seek appropriate medical attention.
  • A medically supervised exercise test can provide a measured maximum heart rate when clinically appropriate.

💡 Limitations

  • This calculator provides a predicted maximum heart rate rather than a measured value.
  • The prediction can have meaningful individual error.
  • It is not a diagnostic tool and does not determine whether an exercise intensity is safe for a particular person.
  • Children and adolescents may require different approaches because adult age-based prediction equations can have limited accuracy in younger populations.

❓ Frequently asked questions

What is maximum heart rate?

Maximum heart rate, or HRmax, is the highest heart rate reached during maximal physical effort. An age-based calculator provides an estimate rather than a direct measurement.

How do I calculate maximum heart rate?

This calculator uses a sex-specific age-based equation. For males it uses 208.609 minus 0.716 times age. For females it uses 209.273 minus 0.804 times age.

Does maximum heart rate depend on gender?

Research has produced both sex-independent and sex-specific prediction equations. This calculator uses the sex-specific equations from a large study because the study found different age-related declines in maximum heart rate for males and females.

What is the 220 minus age formula?

The 220 minus age formula is a traditional age-based estimate of maximum heart rate. It remains widely used as a general guide, including by the American Heart Association, but it is only an estimate.

What is a normal maximum heart rate?

There is no single normal maximum heart rate for every person. Maximum heart rate generally decreases with age, but individuals can differ considerably from age-based estimates.

What should my heart rate be during moderate exercise?

The American Heart Association describes moderate-intensity exercise as approximately 50% to 70% of maximum heart rate. The appropriate range can vary between individuals.

What should my heart rate be during vigorous exercise?

The American Heart Association describes vigorous-intensity exercise as approximately 70% to 85% of maximum heart rate.

Is the calculated maximum heart rate exact?

No. It is a statistical estimate. Research comparing predicted and measured maximum heart rates shows that individual differences can be substantial.

Can medications affect my maximum heart rate?

Yes. Some medicines can affect heart rate and may lower the maximum heart rate you can achieve. If you take medication that affects heart rate, ask your healthcare professional about appropriate exercise intensity.

Can I use this calculator for children?

Age-based adult equations should not automatically be assumed to be accurate for children and adolescents. Research indicates that commonly used equations can have limited accuracy in younger populations.

How can maximum heart rate be measured?

Maximum heart rate can be measured during a properly conducted maximal exercise test, often under professional supervision. A calculator cannot directly measure your heart rate.

Is maximum heart rate the same as resting heart rate?

No. Resting heart rate is measured while you are at rest, whereas maximum heart rate refers to the highest heart rate reached during maximal exercise.
