Quickly estimate your Maximum Heart Rate (MHR) using the standard age-based formula to help set up your cardiovascular training zones.
Maximum Heart Rate (MHR) is the highest number of times your heart can safely beat in one minute during intense physical exercise. It's not a measure of fitness, but rather an age-related guide used to set up personalized cardiovascular training zones.
The most common and widely used formula to estimate MHR is straightforward:
$MHR = 220 - Age$
| Age | Estimated Max HR (bpm) |
|---|---|
| 20 | 200 |
| 30 | 190 |
| 40 | 180 |
| 50 | 170 |
| 60 | 160 |
Note: This is an estimate. Individual MHR can vary. For elite athletes or specific medical conditions, a clinically supervised stress test is the most accurate method.

Estimates an age-predicted maximum heart rate.
The calculator applies the age-based maximum-heart-rate formula configured in the live tool. The calculation uses age.
Age-predicted maximum heart rate is an average estimate and can differ materially from an individual measured maximum. Use the number as an estimate and consider professional advice when the result may affect health, treatment, pregnancy, nutrition, exercise safety or another important decision.
