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

Tip: Use the basic method if you do not know your resting heart rate. Use the Karvonen method for a more personalized estimate.

Your Results

Enter your age and optional resting heart rate to see your estimated maximum heart rate, heart rate reserve, and training zones.

Max Heart Rate 0
Heart Rate Reserve 0
Important: This calculator gives estimated values only. If you have heart disease, high blood pressure, chest pain, breathing issues, or any medical condition, speak with a qualified healthcare professional before starting intense exercise.

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

1

Enter Age

Your age is used to estimate your maximum heart rate using the common 220 minus age formula.

2

Add Resting Rate

If you know your resting heart rate, the Karvonen method can provide more personalized target zones.

3

Select Method

Choose the basic method for quick results or the Karvonen method for heart rate reserve based estimates.

4

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.

Frequently Asked Questions

What is the formula for maximum heart rate?
The common formula is 220 minus your age. For example, if you are 30 years old, your estimated maximum heart rate is 190 beats per minute.
What is a good target heart rate for exercise?
For many people, a moderate workout range is around 60% to 70% of maximum heart rate. More intense cardio training is often around 70% to 85%.
Is the Karvonen method better?
The Karvonen method can be more personalized because it uses your resting heart rate and heart rate reserve, not only your age.
Can beginners use this calculator?
Yes. Beginners can use this calculator to understand safe workout intensity. Start with lower zones and increase intensity gradually.
Is this calculator medical advice?
No. This tool provides general fitness estimates only. Always consult a healthcare professional if you have medical concerns or symptoms.
