Enter the required values to calculate your Resting Metabolic Rate (RMR), which represents the number of calories your body needs at rest.
Related
The RMR calculator estimates how many calories your body needs per day at rest. Your Resting Metabolic Rate (RMR) is a key metric for guiding your diet and fitness goals.
Resting Metabolic Rate represents the calories your body needs to stay alive while at rest.
It provides a baseline for planning your weight goals, whether for loss, gain, or maintenance.
RMR is sometimes used interchangeably with Resting Energy Expenditure (REE) and tends to decrease by approximately 0.01 kcal/min for each 1% increase in body fat. For more accurate body fat measurements, try the body fat calculator.
RMR is often considered the same as BMR. It represents the calories needed for minimal activities, such as sitting or lying down.
The Harris-Benedict Equation is commonly used to estimate Resting Metabolic Rate (RMR):
Men: (13.397 × m + 4.799 × h – 5.677 × a) + 88.362
Women: (9.247 × m + 3.098 × h – 4.330 × a) + 447.593
Where:
On average, 75–100 calories are burned per hour at rest. Roughly, 0.48 calories per pound (0.05 calories per kg) are burned per hour if no activity is performed. This value varies depending on factors like age, gender, and genetics.
To estimate your RMR, use the equations below:
Men: (13.397 × m + 4.799 × h – 5.677 × a) + 88.362
Women: (9.247 × m + 3.098 × h – 4.330 × a) + 447.593
Using an RMR calculator can give you a precise understanding of your body's energy needs at rest, helping you make informed decisions about diet and exercise.
Let’s say John is 26 years old, weighs 75 kg, and is 174 cm tall. Let’s calculate his resting metabolic rate.
Solution:
Given:
Using the RMR formula for men:
RMR = (13.397 × m + 4.799 × h – 5.677 × a) + 88.362
RMR = (13.397 × 75 + 4.799 × 174 – 5.677 × 26) + 88.362
RMR = (1004.775 + 835.026 – 147.602) + 88.362
RMR = 1,692.199 + 88.362 = 1,780.561 calories/day
BMR and RMR are often used interchangeably, but there is a subtle difference.
Basal Metabolic Rate (BMR) refers to the calories your body needs for essential functions at complete rest. Resting Metabolic Rate (RMR) measures calories burned at rest and is also known as Resting Energy Expenditure (REE).

RMR helps you plan your weight loss strategy. Here’s how to use it effectively:
Using a weight loss calculator can help tailor your calorie intake, or consult a medical professional for personalized guidance.
Not necessarily. Short-term fasting doesn’t significantly reduce RMR, but prolonged starvation may affect metabolism. Evidence shows that once normal caloric intake resumes, metabolism generally returns to normal.
A healthy RMR supports your body’s essential functions such as breathing, blood circulation, and digestion. Typical ranges are:
