Target Heart Rate Calculator (Karvonen Formula) for 50-Year-Old at 75% Intensity
Cardiovascular training target for a 50-year-old with a resting heart rate of 65 bpm at 75% intensity.
Calculate your target heart rate for exercise using the Karvonen formula based on maximum heart rate, resting heart rate, and exercise intensity. Enter your Maximum Heart Rate, Resting Heart Rate, Exercise Intensity (Decimal) to get an instant target heart rate (bpm). Formula: ((field1 - field2) * field3) + field2.

How It Works
How It Works
This calculator uses the Karvonen formula to find your target heart rate during exercise. It adjusts your workout intensity based on both your maximum heart rate and your resting heart rate.
First, it subtracts your resting heart rate from your maximum heart rate to find your heart rate reserve. Then it multiplies that number by your chosen exercise intensity. Finally, it adds your resting heart rate back to give your personalized target heart rate.
- Subtract Resting Heart Rate from Maximum Heart Rate
- Multiply the result by your chosen intensity (decimal form)
- Add your Resting Heart Rate back to the result
- The final number is your Target Heart Rate in bpm
Understanding the Results
The result shows the heart rate you should aim for during exercise at your selected intensity. It is measured in beats per minute (bpm).
A lower intensity (like 0.5 or 50%) gives a lower target heart rate for lighter workouts. A higher intensity (like 0.8 or 80%) produces a higher target heart rate for more challenging exercise sessions.
- Measured in beats per minute (bpm)
- Higher intensity means a higher target heart rate
- Lower intensity means a lower target heart rate
- Helps guide safe and effective workouts
Frequently Asked Questions
What is the Karvonen formula used for?
The Karvonen formula is used to calculate your target heart rate for exercise based on your maximum heart rate, resting heart rate, and desired intensity level. It provides a more personalized training zone compared to using maximum heart rate alone. This helps you exercise more effectively and safely.
How do I find my maximum heart rate?
A common estimate for maximum heart rate is 220 minus your age. However, this is only an approximation and may vary between individuals. For more accuracy, a supervised fitness test conducted by a healthcare or fitness professional is recommended.
How should I measure my resting heart rate?
Measure your resting heart rate first thing in the morning before getting out of bed. Count your pulse for 60 seconds for the most accurate reading. This value reflects your heart rate at complete rest and is essential for accurate results.
What does exercise intensity as a decimal mean?
Exercise intensity represents how hard you want to work relative to your heart rate reserve. It must be entered as a decimal, such as 0.5 for 50% intensity or 0.7 for 70% intensity. Higher values correspond to more vigorous workouts.
When should I use this Target Heart Rate Calculator?
Use this calculator when planning cardiovascular workouts like running, cycling, or swimming. It helps you stay within a specific training zone to meet goals such as fat burning, endurance building, or performance improvement. It is especially helpful for structured training programs.
Why is the Karvonen formula more accurate than simple percentage methods?
Unlike basic methods that use only maximum heart rate, the Karvonen formula accounts for your resting heart rate. This makes the result more personalized and reflective of your actual cardiovascular fitness level. As a result, it provides a more precise target heart rate for training.
