Basal Metabolic Rate (BMR) Calculator: Calculates calories burned at rest.
Understand the minimum calories your body needs to function while at rest. This tool is fundamental for anyone looking to manage weight, optimize nutrition, and plan exercise programs, providing the basis for your daily energy requirements.
Basal Metabolic Rate (BMR) Calculator
How to Use the Calculator
This calculator estimates the number of calories your body burns at rest (Basal Metabolic Rate) and your total daily calorie needs based on your activity level. Simply fill in your details, choose your preferred unit system, and click "Calculate".
Your Basal Metabolic Rate (BMR) is:
0
Calories/dayThis is the number of calories your body needs to perform basic, life-sustaining functions if you were to rest for 24 hours.

The Mifflin-St Jeor equation is generally considered more accurate for most people.
Calculate Your Total Daily Calorie Needs (TDEE)
Now, select your daily activity level to find out your Total Daily Energy Expenditure (TDEE) — the total calories you burn in a day.

Glossary of Terms
- BMR (Basal Metabolic Rate)
- The number of calories your body needs to accomplish its most basic (basal) life-sustaining functions, such as breathing, circulation, nutrient processing, and cell production.
- TDEE (Total Daily Energy Expenditure)
- The total number of calories you burn each day. It's calculated by multiplying your BMR by your activity level factor.
Frequently Asked Questions (FAQ)
Yes. Factors like age, weight changes (especially muscle mass), and health conditions can alter your BMR over time.
The most effective way is through strength training to build more muscle mass. Muscle tissue burns more calories at rest than fat tissue.
