BMR Calculator
Loading tool workspace...
Your Basal Metabolic Rate (BMR) is the number of calories your body burns to perform basic life-sustaining functions, like breathing and heart rate, while at rest. Knowing your BMR is the foundation of any successful nutrition or fitness plan.
Combine this with your activity level to determine your total daily energy expenditure (TDEE).
How to Calculate Your BMR
- 1
Select your Gender and enter your current Age.
- 2
Input your Weight and Height using either Metric or Imperial units.
- 3
View your BMR results and see the calorie breakdown for various activity levels.

Mifflin-St Jeor Equation
Our tool uses the most widely accepted scientific formula for calculating BMR in healthy adults.
BMR vs. TDEE
BMR is resting calories. TDEE (Total Daily Energy Expenditure) adds your exercise and daily movement on top of your BMR.
Frequently Asked Questions
How do I use this to lose weight?
Generally, eating roughly 500 calories below your TDEE (BMR + activity) can lead to sustainable weight loss of about 1lb per week.
Can I increase my BMR?
Yes! Building muscle mass is the most effective way to increase your BMR, as muscle burns more calories at rest than fat.
