Maximum Heart Rate Calculator
Enter your age as a whole number (years).
What Is the Maximum Heart Rate Calculator?
This calculator gives a quick estimate of your maximum heart rate (HRmax) using a well-known formula — 220 minus your age. It's mostly used by fitness experts, athletes, trainers, and people tracking their cardio zones during workouts. The value it gives helps you set target heart rate zones for safe, effective exercise intensity.
Just type in your age in years. The tool does the math and shows your estimated HRmax in bpm — that's beats per minute. You’ll also see the equation used right below the result. If you make a mistake or wanna try again, hit the Clear button.
Formula Used in This Tool
The calculation here is based on:
HRmax ≈ 220 − Age
It’s not perfect, yeah, it’s a general formula that works okay for most people, but individual values might be a bit different in reality, depending on your heart condition, fitness level, or even genes.
How to Use the Calculator
- Enter your age as a whole number, like 22, 37, or 65
- Hit Calculate — the tool finds your HRmax
- Click Clear to reset the input and result
- Age must be between 1 and 120
That’s it — no units to convert, no confusion. Everything’s instant. Works best when planning your warmups, aerobic workouts, or high-intensity intervals. Some fitness coaches also use this to find fat burn or VO2 max zones.
