Formula & Methodology of the BMR Calculator (Basal Metabolic Rate, Mifflin St Jeor Equation)
Formula Used in “BMR Calculator (Basal Metabolic Rate, Mifflin St Jeor Equation)”
The Basal Metabolic Rate (BMR) can be calculated using the Mifflin St Jeor Equation, which is widely regarded as one of the most accurate methods for estimating BMR. The standard formula is as follows:
- For men: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(years) + 5
- For women: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(years) – 161
Step-by-Step Breakdown of the Formula
This section breaks down each variable in the Mifflin St Jeor Equation.
- Weight (kg): The individual’s weight in kilograms. To convert pounds to kilograms, divide the weight in pounds by 2.2046.
- Height (cm): The individual’s height in centimeters. To convert height in feet and inches to centimeters, multiply the feet by 30.48 and the inches by 2.54, then sum the two.
- Age (years): The individual’s age in years, which influences metabolic rate as metabolic processes generally slow with aging.
- Gender: This variable affects the calculation due to differences in body composition and metabolic rates between men and women.
Example Calculation
To illustrate how to use the Mifflin St Jeor Equation, let’s assume the following example:
| Input Variable | Value |
|---|---|
| Gender | Male |
| Weight | 75 kg |
| Height | 175 cm |
| Age | 30 years |
Using the formula for men:
- BMR = 10 × 75 + 6.25 × 175 – 5 × 30 + 5
- BMR = 750 + 1093.75 – 150 + 5
- BMR = 1698.75
The individual’s Basal Metabolic Rate (BMR) is approximately 1699 calories/day. This means that this person would need to consume about 1699 calories per day to maintain their weight at complete rest, without any physical activity.

How to Use “BMR Calculator (Basal Metabolic Rate, Mifflin St Jeor Equation)”
Follow these simple steps to effectively use the BMR (Basal Metabolic Rate) calculator based on the Mifflin St Jeor Equation:
- Access the BMR Calculator:
Visit the appropriate website or application offering the BMR Calculator for the Mifflin St Jeor Equation.
- Select Your Gender:
Choose either “Male” or “Female.” Gender affects calorie requirements due to differences in body composition.
- Enter Your Age:
Input your age in years. This is crucial, as metabolic rates typically decrease with age.
- Input Your Weight:
Provide your weight in either pounds or kilograms. Weight significantly influences your BMR.
- Enter Your Height:
Fill in your height using either inches or centimeters. Height impacts the calculation of your BMR.
- Calculate Your BMR:
Click the “Calculate” button to obtain your Basal Metabolic Rate.
Understanding the Input Fields
It’s essential to know what each input field represents to ensure accurate calculations:
- Gender: Affects the calculation because men typically have a higher muscle mass than women, impacting metabolic rate.
- Age: As you age, your metabolism tends to slow, making age a key factor.
- Weight: More weight can mean a higher BMR as your body requires more energy to function.
- Height: Taller individuals usually have a larger body mass, which can increase BMR.
For example, a 30-year-old male weighing 180 pounds and 6 feet tall will have a different caloric need than a 30-year-old female of the same weight and height due to physiological differences.
How to Interpret the Results
Once you’ve calculated your BMR, you will receive a number that represents the calories your body needs at rest to maintain essential functions like breathing and circulation.
- Understanding the Number: This BMR value is in calories. For example, a BMR of 1800 means you burn 1800 calories at rest daily.
- Common Mistakes:
- Confusing pounds with kilograms or vice versa. Always check units to ensure accuracy.
- Ignoring the impact of muscle mass versus fat in the body’s composition. Muscle burns more calories than fat, which can skew BMR results.
- Not considering additional activity levels. BMR is just a baseline; you may need more calories depending on your daily activity.
