BMR Calculator
Use this BMR calculator to estimate basal metabolic rate, which is a rough measure of resting energy needs. It is an educational tool for understanding metabolism concepts, not a medical assessment.
Estimated BMR
1,758 kcal/day
Basal metabolic rate is a resting-energy estimate, not a diagnosis or personal nutrition plan.
How this calculator works
This tool uses a common BMR formula built from age, sex, height, and weight. It estimates the energy your body may use at rest before daily movement and exercise are layered on top.
That makes it a useful foundation for broader calorie planning. If you want the next step beyond resting metabolism, use the calorie calculator.
What the result means
The result is a resting-energy estimate expressed in calories per day. It is not the same thing as maintenance calories, because most people burn more than their BMR once activity is included.
In practical use, the number is best treated as a baseline rather than as a daily eating target by itself.
Important limitations
Formula-based BMR estimates cannot capture every individual difference. They do not directly measure metabolism, hormone status, or clinical health conditions.
This calculator does not provide diagnosis or medical advice. For a personalized interpretation, consult a qualified healthcare professional.
When to use this calculator
Use this calculator when you want to understand the resting side of calorie planning, compare scenarios, or learn how BMR fits into total daily energy estimates.
It works well alongside what BMR is, the calorie calculator, and the health hub.

FAQs
Is BMR the same as total calories burned in a day?
No. BMR is a resting estimate, while total daily energy use usually includes movement and activity.
Can online tools measure metabolism exactly?
No. They estimate metabolism with formulas rather than direct testing.
Why does age affect BMR?
Age is one of the common inputs used by formula-based estimates because energy needs often shift over time.
Should I base medical decisions on this result?
No. This is an educational estimate and not a substitute for professional care.
Is this medical advice?
No. It is a general educational calculator only.
