Maximum Heart Rate Calculator
Estimate your maximum heart rate, the basis for training heart-rate zones.
The top of your range
Maximum heart rate is roughly the highest your heart can beat during all-out effort, and it is the reference point from which training zones are calculated. This estimates it, commonly from your age, giving the anchor for heart-rate-based training.
Enter your age to estimate your maximum heart rate.
A rough estimate, and its uses
The familiar age-based estimate — subtracting your age from a fixed number — is convenient but genuinely rough, because true maximum heart rate varies considerably between individuals of the same age, so your actual maximum could be meaningfully higher or lower than the formula suggests. It is fine as a starting point for setting training zones, but athletes seeking precision often use a measured test instead. Maximum heart rate also naturally declines with age, which is normal. This is general information, not medical advice; if you have any heart condition or are starting intense exercise, it is wise to consult a doctor before training near your limits.
Common questions
How is maximum heart rate estimated?
Commonly from age, using a simple formula. It is a rough estimate, since true maximum varies considerably between people of the same age.
What is it used for?
As the reference point for calculating training heart-rate zones, so you can target different intensities of exercise.
Is this medical advice?
No — it is general information. If you have a heart condition or are starting intense exercise, consult a doctor before training near your limits.
