The fat burning zone calculator estimates the target heart rate required to achieve the desired level of fat loss.

What is Fat Burning Zone?

The fat-burning zone is the optimal fat burning rate achieved during aerobics or exercise that is considered ideal for your fat loss. It is necessary to calculate the fat burning zone and keep your heartbeat per minute at a normal rate. The fat-burning zone is directly related to the heartbeat and your heart rate. If you want to lose weight by exercising and workout, then use the fat burn heart rate calculator.

How to Calculate Fat Burning Zone?

There are 3 methods to calculate your fat burning zone:

  • 60-80% of your maximum heart rate
  • Zoladz method
  • Karvonen method

Let’s try to estimate the fat burning zone for a person that is 30 years of age and resting heart rate of 60. 

First, we need to measure the maximum heart rate according to age: 

MHR = 220 – age

MHR = 220 – 30

MHR = 180

The MHR (Maximum Heart Rate) for a person =  220 – age

The 60-80% of Maximum Heart Rate:

Fat Burning Zone =  [60% x 180] – [80% x 180]

Fat Burning Zone = 108 – 144 BPM

 BPM  stands for the beats per minute

The Zoladz Method:

Fat Burning Zone = HRmax − Adjuster ± 5 bpm

Fat Burning Zone =  [180 – 50 ± 5] – [180 – 40 ± 5]

Fat Burning Zone =  130 – 140 BMP


HRmax stands for maximum heart rate

Karvonen Method:

Fat Burning Zone= ((MHR − RHR) × % intensity) + RHR

Fat Burning Zone=  [((180 − 60) × 60%) + 60] – [((180 − 60) × 80%) + 60]

Fat Burning Zone =  [120 x 60% + 60] – [120 x 80% + 60]

Fat Burning Zone = 132 – 156 BPM

It seems complicated to find the fat-burning zone, use the fat burning heart rate calculator to obtain your result in a matter of few seconds. You can estimate the intensity and the time of your exercise by measuring the burning fat zone. The heart rate increases during the exercise and the harder you exercise the more your heart rate increases.

71–75 101–104

The fat-burning zone will change while you grow and get older. If you are finding any difficulty in measuring what is my fat burning zone, just use the fat burning zone calculator and know yours.
