BMR Calculator
Estimate your Basal Metabolic Rate (BMR) – the calories your body burns at rest – using the Mifflin-St Jeor equation.
Estimate your Basal Metabolic Rate (BMR) using the validated Mifflin-St Jeor equation.
[!NOTE] BMR calculations are statistical estimates based on population averages. They do not substitute for professional medical advice or clinical diagnostic evaluation.
Formula & Method
- BMR for Men:
(10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5 - BMR for Women:
(10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
Worked Example
For a 30-year-old male, height 180 cm, weight 75 kg:
BMR = 10(75) + 6.25(180) - 5(30) + 5 = 750 + 1,125 - 150 + 5 = 1,730 kcal/day
Frequently Asked Questions
What is Basal Metabolic Rate (BMR)?+
BMR is the estimated number of calories your body needs to perform basic life-sustaining functions (like breathing, circulation, and cell production) while at complete rest.
Which formula does this BMR calculator use?+
It uses the Mifflin-St Jeor equation, widely recognized in clinical research as one of the most accurate BMR estimation formulas.
Is this calculation medical advice?+
No. BMR estimates provide general educational guidance. Consult a healthcare professional or registered dietitian for clinical health assessment.
