Calorie Heart Rate Calculator

Your target heart rate for exercise is approximately 0 bpm.


When engaging in physical activity, it’s important to monitor and control your heart rate to ensure that you are working out at the right intensity. The Calorie Heart Rate Calculator is a valuable tool that helps you determine your target heart rate for exercise. By considering factors such as your age, resting heart rate, and exercise intensity, you can achieve optimal workout results while maintaining your health and safety.


The calculator utilizes the Karvonen formula to calculate your target heart rate. This formula takes into account your age, resting heart rate, and exercise intensity as a percentage of your maximum heart rate (Max HR). Here’s the formula in plain text:

  1. Subtract your age from 220 to find your Max HR.
  2. Calculate your Heart Rate Reserve (HRR) by subtracting your resting heart rate from your Max HR.
  3. Determine your target heart rate by multiplying your HRR by the exercise intensity as a decimal (e.g., 60% intensity is 0.60) and adding your resting heart rate.

How to Use

Using the Calorie Heart Rate Calculator is a simple process:

  1. Enter your age in years.
  2. Input your resting heart rate in beats per minute (bpm). Measure this when you are at rest, typically in the morning.
  3. Specify your exercise intensity as a percentage of your Max HR. For example, if you want to work at 60% of your Max HR, enter 60.

Click the “Calculate” button, and the calculator will provide your target heart rate for exercise.


For instance, if you are 30 years old, have a resting heart rate of 70 bpm, and want to work out at 70% of your Max HR, you can use the calculator as follows:

  • Age: 30 years
  • Resting Heart Rate: 70 bpm
  • Exercise Intensity: 70%

Upon clicking “Calculate,” the calculator will display your target heart rate for exercise, which is crucial for effective and safe workouts.


  1. What is the target heart rate for exercise, and why is it important? The target heart rate is the ideal heart rate range for efficient and safe exercise. It ensures you are working out at the right intensity.
  2. How can I measure my resting heart rate? Measure your resting heart rate when you wake up, while still lying in bed. Use a timer and count the beats for one minute.
  3. Why is age a factor in the Karvonen formula? Age affects your Max HR, which is used to determine your target heart rate.
  4. What is the significance of exercise intensity as a percentage of Max HR? It allows you to tailor your workouts to achieve specific fitness goals, such as fat burning or cardiovascular improvement.
  5. Is it safe to exercise at a high intensity close to my Max HR? High-intensity workouts are safe for many people, but it’s crucial to consult a healthcare professional, especially if you have health concerns.
  6. Should I monitor my heart rate during exercise to ensure I’m in the target zone? Monitoring your heart rate during exercise can help you stay within your target heart rate zone.
  7. How often should I calculate my target heart rate? You can calculate your target heart rate whenever your fitness goals change or your resting heart rate significantly varies.
  8. Can I use the Karvonen formula for different types of exercise? Yes, the formula can be used for various activities, from cardio workouts to strength training.
  9. Are there different target heart rate zones for different fitness goals? Yes, there are different target zones for fat burning, endurance, and cardiovascular fitness.
  10. Is it necessary to consult a healthcare professional before using a target heart rate for exercise? It’s advisable, especially if you have pre-existing health conditions or are new to exercise.


The Calorie Heart Rate Calculator is a valuable tool for individuals looking to optimize their workouts and ensure they are exercising at the right intensity. By understanding and using your target heart rate, you can achieve fitness goals, improve cardiovascular health, and enjoy the benefits of safe and efficient exercise. Remember to monitor your heart rate during workouts and seek guidance from a healthcare professional if needed.
