Max Heart Rate Calculator

Estimate the upper limit of your heart rate during exercise.

How the Math Works

The Max Heart Rate Calculator uses two well-established formulas to estimate your maximum heart rate. The traditional formula subtracts your age from 220 (220 - age), providing a quick estimate based on decades of research. The Tanaka formula offers a more refined approach, calculating 208 minus 0.7 times your age (208 - 0.7 × age), which studies show may be more accurate for certain populations. Both equations recognize that cardiovascular capacity naturally declines with age, though at different rates.

Practical Applications

To use this calculator, simply enter your age in years and select either formula based on your preference or fitness goals. Once you have your estimated maximum heart rate, you can determine target training zones by multiplying it by percentages (for example, 70% for moderate intensity or 85% for vigorous exercise). This calculation is particularly valuable for structuring workouts, monitoring exercise intensity, and ensuring you're training within safe and effective heart rate ranges.

Day-to-Day Use

Knowing your maximum heart rate helps you exercise more intelligently in everyday life. Whether you're walking your dog, taking a fitness class, or working out at the gym, you can now gauge whether you're pushing too hard or not challenging yourself enough. This information is useful for setting realistic fitness goals, tracking improvements in cardiovascular health over time, and communicating with fitness professionals or healthcare providers about appropriate exercise intensities for your age and condition.

Worked example

Age 30 → 190 bpm (Tanaka 187).
