Maximum Heart Rate Calculator by Age

What is the Maximum Heart Rate Calculator – Training Limit?

The maximum heart rate calculator estimates your maximum heart rate using different formulas and shows a safe training zone. This is useful for beginner exercisers who want to ensure the effectiveness of their training.

The calculator is free and works in the browser without registration. This site offers over 200 calculators.

Calculation Principle

Fox: HRmax = 220 − age. Tanaka: HRmax = 208 − 0.7 × age. Training with reserve heart rate: HR = HRres × intensity% + resting heart rate

Enter your information in the calculator fields – the result updates immediately. You can try different values to compare scenarios.

Practical Example

42 years old, resting heart rate 62 bpm → HRmax (Tanaka) = 178 bpm. Reserve heart rate = 116. Aerobic zone 60% = 131 bpm.

This example illustrates a typical situation. Enter your own information to get a personalized result.

Who is the calculator suitable for?

The calculator serves individuals, entrepreneurs, students, and professionals. All calculators on this site are free and no registration is required.

The results are indicative – official decisions are always made based on calculations by professionals.

Tips and Considerations

• As a beginner, stay in the 50–70% HRmax range for the first 4–8 weeks.
• Using the reserve heart rate (Karvonen) provides a more accurate training zone than a direct percentage of HRmax.
• If you do not own a heart rate monitor, try the talk test: during aerobic exercise, you should be able to speak complete sentences.
