BMR Calculator – Calculate Your Basal Metabolic Rate Instantly
Know how many calories your body needs at rest with our free online BMR Calculator.
BMR & TDEE Calculator
🧮 BMR Formula (With Example)
BMR (Basal Metabolic Rate) is calculated using the Mifflin-St Jeor Equation, one of the most accurate methods:
BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
For Women:
BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161
📌 Example Calculation (For a Male):
- Weight = 70 kg
- Height = 175 cm
- Age = 25 years
BMR = (10 × 70) + (6.25 × 175) – (5 × 25) + 5
BMR = 700 + 1093.75 – 125 + 5 = 1673.75 kcal/day
This means the person needs approximately 1674 calories per day to maintain basic body functions at rest.
