Understanding your Basal Metabolic Rate (BMR) is essential for achieving your fitness and health goals. Our BMR Calculator provides an accurate estimation of the calories your body needs to perform its basic functions, such as breathing, circulation, and cell production. Use this tool to create a diet and exercise plan that aligns with your needs.
What is BMR?
BMR (Basal Metabolic Rate) is the number of calories your body requires to maintain essential bodily functions while at rest. It represents the minimum energy expenditure needed for survival.
Key Functions of BMR
- Regulating body temperature.
- Supporting organ function.
- Maintaining muscle and tissue health.
Why is Knowing Your BMR Important?
Calculating your BMR helps you:
- Set Weight Goals: Whether you aim to lose, maintain, or gain weight, BMR provides a starting point for calorie adjustments.
- Personalize Nutrition: Determine your daily caloric needs to avoid over- or under-eating.
- Enhance Workout Efficiency: Understand how many calories to burn for effective weight management.

How is BMR Calculated?
Most calculators use these common formulas:
1. Harris-Benedict Equation: For men:
BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) − (5.677 × age in years)
For women:
BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) − (4.330 × age in years)
2. Mifflin-St Jeor Equation (more recent and accurate):
For men:
BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + 5
For women:
BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) − 16
Factors That Influence BMR
Your BMR is affected by several factors:
- Age: BMR decreases with age due to muscle loss and a slower metabolism.
- Gender: Men typically have a higher BMR due to a greater muscle mass.
- Body Composition: More muscle increases BMR; fat has a lower metabolic activity.
- Height: Taller individuals generally have a higher BMR.
- Health Conditions: Certain conditions, like thyroid disorders, can alter BMR.

Frequently Asked Questions
While our calculator provides a reliable estimate, your actual BMR may vary slightly based on unique physiological factors.
Recalculate your BMR whenever there’s a significant change in your weight, age, or activity level.
BMR for women average around 1,400, while BMR for men average between 1,600 and 1,800 is good.
The calories burn between a day ranges from 1,300 to more than 2,000, depending on your age and sex.
