The RMR calculator estimates how many calories your body needs per day at rest. Your Resting Metabolic Rate (RMR) is the best indicator to make decisions about your diet and fitness goals.
Resting Metabolic Rate is the equivalent of calories you need to stay alive while at rest.
It provides a baseline to schedule your weight goals including weight loss, gain, and maintenance.
RMR is interchangeably used with Resting Energy Expenditure (REE) and decreases by 0.01 kcal/min for each 1% increase in body fat. For precise body fat estimations, use the body fat calculator.
Most often, RMR is considered as BMR. But it refers to your daily calorie needs required to perform low-energy tasks like sitting or lying down.
The following Harris-Benedict Equation is commonly used to estimate resting metabolic rate (RMR):
Men: (13.397m + 4.799h – 5.677a) + 88.362
Women: (9.247m + 3.098h – 4.330a) + 447.593
Where
Approximately 75-100 calories are burnt at rest in one hour. If an individual does nothing then 0.48 calories per pound of weight or 0.05 calories per kilogram of weight per hour are burned. This is not the exact amount, because it changes from person to person depending upon factors like age, gender genetics, etc.
To figure out the RMR use the following equations:
Men: (13.397m + 4.799h – 5.677a) + 88.362
Women: (9.247m + 3.098h – 4.330a) + 447.593
For convenience, and precision in understanding your body's energy needs at the rest state, use the RMR calculator. It provides valuable insights into the resting metabolic rate and helps in making informed decisions about your diet and exercise.
Let’s say John is 26 years old! Assuming the body weight is 75 kg and height is 174 cm, find the resting metabolic rate.
Solution:
Given that:
Put these values in the RMR Formula:
RMR = (13.397m + 4.799h – 5.677a) + 88.362
RMR = (13.397*75 + 4.799*174 – 5.677*26) + 88.362
RMR = 1004.775 + 835.026 – 147.602 + 88.362
RMR = 1,928.163 – 147.602 = 1,780.561 resting calories burned
Both the terms BMR and RMR can be used interchangeably, but there is a slight variation.
The basal metabolic rate (BMR) is the number of calories that your body requires for basic functions while the resting metabolic rate (RMR) is the number of resting calories that your body burns at rest. It is also known as resting energy expenditure (REE).

RMR is a deciding factor in planning your weight loss calendar. Let's see how you can use it for weight loss!
Using of weight loss calculator also enables you to tailor your calorie intake or consult a medical professional for a better prescription.
Not actually! Fasting does not impact your resting metabolic rate, but starving for a long time can cause severe changes in your metabolism. However, no evidence supports the theory. Once you start to intake normal calories, your metabolism will continue to function at a normal rate.
A good resting metabolic rate (RMR) aligns with your individual physiological needs (respiration, blood circulation, food digestion, etc.) and supports overall health. For men, it is 1,800 to 2,400 calories while for women, it ranges from 1,200 to 1,800 calories per day.
