What Is The Most Accurate Way To Calculate Your Bmr

What does BMR Stand for, and what is its importance

Allcalculator.net, your go-to online resource for health and fitness calculations, offers an accurate and user-friendly BMR calculator to determine your Basal Metabolic Rate.

The Value of BMR is determined by measuring a person's gender, age, height, and Weight. BMR value is crucial while a person is on a weight loss journey or needs it for medical purposes. Allcalculator.net offers a user-friendly BMR calculator that accurately calculates your Basal Metabolic Rate based on your unique characteristics, providing you with valuable insights to support your weight management goals.

BMR Calculator

Our BMR Calculator is a simple yet accurate way of calculating the BMR value of a person. It's the most accurate tool for understanding how many calories your body needs at rest. For accurate calculation of BMR, the Calculator needs some details like age, Weight, gender, and height. The Calculator uses any of the equations per your details to provide an accurate BMR value.

The most important thing to note is that the regular consumption of fluid volumes and ions utilizes more energy. These concentrations are adjusted automatically and preserved in the body to maintain homeostasis. Some particles are transported within our body from one part to another and require energy. On the whole, it requires a lot of energy. It is why the central nervous system consumes more energy than BMR.

People tend to use more energy in comparison to BMR

It is because of a person's little or more movement, like walking, running, or exercising. To utilize less energy, one has to be physically less active. BMR is calculated during a period of sleep.

The BMR accounts for at least 60-75% of the energy used. It is closely related to a person's lifestyle and physical activity. Likewise, the Body Surface Area, Body Fat, and many other factors affect the BMR of a person.

So how do you calculate the BMR value to get the most accurate results?

Once you have the BMR of yourself, you can make the necessary changes as to how many calories you need to consume on average or to maintain your Weight. It is important to mention your energy-using activities to calculate the BMR more accurately. In the Calculator, if you also input 10 percent of your digestion. You can get the most accurate BMR value by following these steps.

The following is the method to calculate your BMR.

  • Measure your Weight and input it into the BMR Calculator. Make sure to input the correct values for accurate results.
  • Check your height and input it in the Height column of the BMR Calculator.
  • Next, Input your age in the Calculator.
  • Lastly, select your gender. It is important because the limits of BMR differ for men and women.
  • Now within seconds, the BMR Calculator will determine your BMR value, and you can make necessary changes in your calorie intake and activity level.

The most accurate calculations provided by the BMR Calculator are by using the following equations.

  • Mifflin-St Jeor equation.

The equation is considered one of the most accurate equations to calculate the BMR. Then the Harris-Benedict Equation was also revised.

To calculate the BMR For men:

BMR = 10W(kg) + 6.25H(cm)- 5A(y)+ 5

To calculate the BMR for women:

BMR = 10W(kg) + 6.25H(cm) - 5A(y) - 161

Harris-Benedict Equation

There were generally two equations of Harris-Benedict, but the latter provided more accurate results. It makes it another most accurate way or equation to calculate the BMR. Hence the revised equation of the Harris-Benedict is the most accurate way of calculating your BMR.

To calculate the BMR For men:

BMR = 13.397W(kg)+ 4.799H(cm) - 5.677A(y) + 88.362

To calculate the BMR For women:

BMR = 9.247W(kg) + 3.098H(cm) - 4.330A(y) + 447.593

Katch-McArdle Equation

It differs from the other equations as it calculates the resting energy expenditure. It considers lean muscle mass, which is not considered by the other equations. It is the most accurate way of calculating the BMR of a person who is lean or has more muscle mass.BMR = 370 + 21.6(1 - F)W(kg)

Here W indicates Weight.H=HeightA=Age and F=Body Fat in percentage.

These are the formulas adjusted and used by the Calculator to determine your BMR. Of all these mentioned equations, the most accurate results of BMR are achieved through Mifflin-St Jeor Equation.Katch-McArdle Equation can provide accurate results for lean people who know the value of their muscle mass. One can use the above equation per their choice and calculate the BMR. Or you can use our BMR Calculator to avoid the hassle of calculating it manually. Not only will it be accurate and easy, but it will also be free to calculate your BMR.


The Basal Metabolic Rate or BMR Calculator can determine the energy expenditure while your body is at rest. Or you can use the above equations to compare and calculate. Although the Calculator uses the same equation, it is the most accurate way to calculate your BMR.

With AllCalculator.net's BMR calculator, you can effortlessly calculate your Basal Metabolic Rate, taking into account factors such as age, weight, height, and gender. Get accurate results and valuable insights to optimize your calorie intake and activity level for effective weight management.
