Target Heart Rate Calculator is a health and wellness calculator that helps you calculate target heart rate values from your input data. The formula used is: Target HR = (Max HR − Resting HR) × Intensity% + Resting HR (Karvonen Formula). Enter values using the units shown next to each input field (e.g. kg, cm, years).

Formula

Target HR = (Max HR − Resting HR) × Intensity% + Resting HR (Karvonen Formula)

Example Calculation

Inputs
  • Age: 35 years
  • Resting Heart Rate: 70 bpm
  • Target Intensity: 70 %

Suppose you enter: Age = 35, Resting Heart Rate = 70, Target Intensity = 70. The calculator applies the formula (Target HR = (Max HR − Resting HR) × Intensity% + Resting HR (Karvonen Formula)) and shows all output values below. Change any input field to immediately see how the result changes.
