About this calculator

What is the Maximum Heart Rate Calculator?

The maximum heart rate calculator estimates the maximum heart rate using several formulas. The Tanaka formula (208 − 0.7 × age) is more accurate than the traditional 220 − age, especially for those over 40 years old.

The calculator is completely free, works directly in the browser, and does not store personal information. All calculators on this site are based on up-to-date information.

Calculation Principles

220 − age (Fox, 1971). Tanaka: 208 − 0.7 × age. Gulati (for women): 206 − 0.88 × age.

Enter your measurements into the calculator fields and press the calculate button – the result will be displayed immediately. You can try different values to compare various scenarios.

Practical Example

A 45-year-old woman: Fox 175, Tanaka 176.5, Gulati 166 bpm. Gulati is more accurate for women.

The result is an estimate – for precise clinical measurements, consult a healthcare professional.

Purpose of the Calculator

The calculator is suitable for self-monitoring health, planning workouts, and general health literacy. Tracking values over time provides valuable insights into changes in the body.

Remember that a single measurement result does not tell the whole story – what matters more is the direction and trend over multiple measurement periods.

Practical Tips

  • Use the Tanaka or Gulati formula instead of the 220−age formula after the age of 40.
  • Determine your actual HRmax with a stress test if you are doing serious training.
  • Resting heart rate is a more practical fitness indicator than HRmax.
