Calculate your Maximum Heart Rate (MHR) and Target Heart Rate (THR) zones.Target Heart Rate Calculator ❤️🔥
Target Heart Rate Calculator – Find Your Ideal Exercise Heart Rate Zones
A Target Heart Rate Calculator is a useful fitness tool that helps you determine your maximum heart rate (MHR) and calculate your target heart rate (THR) zones in beats per minute (bpm). These zones guide you on how hard your heart should be working during exercise to achieve specific fitness goals such as fat burning, cardiovascular endurance, or peak performance. This calculator is designed for adults aged 19 years and older and provides accurate, easy-to-understand results.
What Is a Target Heart Rate Calculator?
A Target Heart Rate Calculator estimates your ideal heart rate range during physical activity based on proven heart rate formulas. By understanding your MHR and THR zones, you can exercise more effectively, avoid overtraining, and improve overall cardiovascular health.
This calculator supports multiple calculation methods, allowing you to choose the approach that best matches the data you have available.

What Is Maximum Heart Rate (MHR)?
Maximum Heart Rate (MHR) is the highest number of times your heart can beat per minute during intense physical activity. It is commonly estimated using age-based formulas and serves as the foundation for determining target heart rate zones.
A widely used formula is:
MHR = 220 − Age
The Target Heart Rate Calculator can also use a measured maximum heart rate if you have one, providing more personalized and accurate results.
What Are Target Heart Rate (THR) Zones?
Target Heart Rate (THR) zones represent different intensity levels of exercise, expressed as a percentage of your MHR. Each zone supports specific fitness goals:
- 50–60% of MHR: Light activity and warm-up
- 60–70% of MHR: Fat-burning zone
- 70–80% of MHR: Aerobic and endurance training
- 80–90% of MHR: High-intensity training
- 90–100% of MHR: Maximum effort and performance training
The calculator displays these zones clearly in beats per minute.
How the Target Heart Rate Calculator Works
This calculator can determine THR zones using different input methods:
- Age only: Estimates MHR and calculates THR zones.
- Age and resting heart rate (RHR): Uses the Karvonen formula for more accuracy.
- Measured MHR and measured RHR: Provides the most personalized target heart rate zones.
By selecting the method that matches your available data, you get results that suit your fitness level and goals.
Target Heart Rate Formula (Karvonen Method)
When resting heart rate is included, the calculator uses the Karvonen formula:
THR = [(MHR − RHR) × Intensity] + RHR
Where:
- MHR = Maximum Heart Rate
- RHR = Resting Heart Rate
- Intensity = Desired training percentage
This method is often preferred because it accounts for individual fitness differences.
How to Use the Target Heart Rate Calculator
Using the calculator is simple:
- Enter your age (and optionally your resting heart rate or measured MHR).
- Choose the calculation method.
- Click Calculate.
- View your maximum heart rate and target heart rate zones in bpm.
The results help you tailor workouts to your fitness goals safely and effectively.
