Heart Rate Calculator
Calculate your estimated maximum heart rate and target heart rate zones for different workout intensities. This tool helps you understand whether your training is light, moderate, fat-burning, cardio-focused, or high intensity.
Calculate Heart Rate Zones
Your Results
Enter your age and optional resting heart rate to see your estimated maximum heart rate, heart rate reserve, and training zones.
Training Zones
Heart rate zones help you understand workout intensity. Lower zones are useful for warm-ups and recovery, while higher zones improve cardio performance and endurance.
Fat Burn Range
Moderate intensity workouts are often used for steady calorie burning. This calculator shows a practical range where many people can train comfortably for longer periods.
Cardio Guidance
Your target heart rate can help you avoid training too lightly or pushing too hard. It gives a simple direction for safer and smarter workouts.
What Is a Heart Rate Calculator?
A Heart Rate Calculator estimates your maximum heart rate and target heart rate zones based on your age. These zones are commonly used during walking, running, cycling, gym workouts, HIIT, and other cardio activities.
Instead of guessing your workout intensity, this tool gives you a clear beats-per-minute range for different exercise levels. It is especially useful for beginners, fitness learners, personal training websites, and health-related content pages.
How It Works
Enter Age
Your age is used to estimate your maximum heart rate using the common 220 minus age formula.
Add Resting Rate
If you know your resting heart rate, the Karvonen method can provide more personalized target zones.
Select Method
Choose the basic method for quick results or the Karvonen method for heart rate reserve based estimates.
View Zones
The tool displays warm-up, fat burn, cardio, hard training, and maximum intensity zones.
Heart Rate Zone Guide
Heart rate zones are usually shown as a percentage of your maximum heart rate. A lower percentage means easier effort, while a higher percentage means more intense exercise.
- 50% - 60%: Light activity, warm-up, recovery, and easy movement.
- 60% - 70%: Fat burn and comfortable steady exercise.
- 70% - 80%: Cardio training for stamina and endurance.
- 80% - 90%: Hard effort for performance-focused workouts.
- 90% - 100%: Maximum intensity, usually for short bursts only.
