What is Target Heart Rate Calculator?

A target heart rate calculator finds the heart rate zone you should train in for cardiovascular fitness, based on your age and resting heart rate.

Training in the right zone — typically 60-85% of your maximum heart rate — maximizes fitness gains safely.

How does the Target Heart Rate Calculator work?

Max HR = 220 – Age | Target Zone = Max HR × 0.6 to 0.85

The Karvonen method refines this using your resting heart rate for more personalized zones.

The calculator shows fat-burn, cardio, and peak zones.

How to use the Target Heart Rate Calculator?

  1. Enter your age and resting heart rate.
