How to Use the BMR Calculator

The BMR Calculator estimates your Basal Metabolic Rate, the number of calories your body needs at rest, based on age, gender, weight, and height. This tool helps you plan your diet and fitness goals.

Step-by-Step Guide

  1. Enter your age in years (e.g., 30).
  2. Select your gender: Male or Female.
  3. Enter your weight in kilograms (e.g., 70 kg).
  4. Enter your height in centimeters (e.g., 170 cm).
  5. Click “Calculate Now” to compute your BMR instantly.
  6. Review your BMR result in calories per day and tips for managing calorie intake.
  7. Use “Calculate Again” to adjust inputs or try different settings.

The calculator uses the Mifflin-St Jeor Equation: for men, BMR = 10 × Weight + 6.25 × Height − 5 × Age + 5; for women, BMR = 10 × Weight + 6.25 × Height − 5 × Age − 161. Results provide your daily calorie needs at rest to guide diet planning.
