- ✓Uses the Mifflin–St Jeor equation
- ✓Simple metric inputs in centimetres and kilograms
- ✓Instant daily calorie estimate with no sign-up
Calculate Your BMR

This is an estimate of energy use at rest. Your total daily calorie needs are usually higher because normal movement and exercise are not included.
What Is BMR?
BMR stands for Basal Metabolic Rate. It estimates the calories your body needs to maintain essential functions while you are at rest.
Your body uses energy even at rest
Breathing, circulation, brain activity, temperature regulation and organ function all require energy. BMR is an estimate of this minimum daily energy use.
BMR does not represent the calories you normally burn across an entire day because it does not include walking, work, exercise or most other activity.
How the estimate works
The calculator uses your age, sex, height and weight.
The result is shown as estimated calories used per day at rest.
BMR Formula Used by This Calculator
The Mifflin–St Jeor equation is used to estimate BMR from common body measurements.
For men
For women
BMR vs TDEE: What Is the Difference?
The two numbers are related, but they answer different questions about your energy needs.
BMR
Estimates the calories your body may use at complete rest.
- Does not include exercise
- Does not include normal daily movement
- Acts as a base energy estimate
TDEE
Estimates your total daily calorie use after activity is included.
- Starts with a BMR estimate
- Applies an activity factor
- Better suited for daily calorie planning
How to Use Your BMR Result
Your BMR is useful for understanding your baseline energy needs, but it should not automatically be treated as a daily eating target.
For maintenance calories
Use your BMR as the base of a TDEE calculation. TDEE adds an activity multiplier so the estimate better reflects your normal day.
For weight goals
Weight-loss or weight-gain planning is usually based on estimated TDEE rather than BMR alone. Your needs can also change as your body weight or activity changes.
Frequently Asked Questions
Quick answers to common questions about Basal Metabolic Rate.
What does BMR mean?
BMR means Basal Metabolic Rate. It is an estimate of the energy your body uses to maintain essential functions while at rest.
Is BMR the same as maintenance calories?
No. Maintenance calories usually refer to TDEE, which includes BMR plus daily movement and exercise.
Can I eat exactly my BMR calories every day?
BMR is not designed to be a universal calorie target. Your total daily needs are usually higher because you also use energy through normal activity.
Why does age affect BMR?
Age is one of the variables used in the Mifflin–St Jeor equation. The formula generally produces a lower estimate as age increases when other inputs stay the same.
Does muscle mass affect BMR?
Body composition can affect real energy needs, but this calculator does not directly measure muscle mass. It estimates BMR using age, sex, height and weight.
How often should I recalculate BMR?
Recalculate when your body weight changes noticeably or when you want an updated baseline estimate.
