A Heart Rate Calculator is a specialized tool that estimates your maximum heart rate, resting heart rate, and target training zones based on your age and fitness level. Our calculator uses the proven 220-age formula for maximum heart rate and the Karvonen method for target zones, providing accurate results for users in India, USA, UK, Canada, Australia, and worldwide.
A normal resting heart rate for adults typically ranges from 60-100 beats per minute (BPM). However, highly trained athletes may have resting rates of 40-60 BPM. For children, normal ranges are higher: newborns (120-160), infants (80-140), children 1-10 years (70-130). Our heart rate calculator by age provides personalized ranges based on your specific demographic and fitness level.
For optimal fat burning, target 60-70% of your maximum heart rate. This is known as the fat burn zone. Our heart rate calculator for weight loss automatically calculates this range based on your age and resting heart rate. For a 30-year-old with a resting HR of 70, this would typically be 129-144 BPM using the Karvonen method.
Maximum heart rate (MHR) is the highest number of beats per minute your heart can achieve during maximum exertion, typically calculated as 220 minus your age. Target heart rate is the ideal range for exercise intensity, usually 50-85% of your MHR. Our target heart rate calculator provides specific zones for different training goals including fat burning, cardio fitness, and peak performance.
Our heart rate calculator is highly accurate for runners, cyclists, and athletes of all levels. It incorporates both the standard maximum heart rate formula and the more precise Karvonen method that accounts for individual fitness levels through resting heart rate. For professional athletes, we recommend using a heart rate monitor during actual training for the most precise measurements.
