Formula and Calculation Method
Our Weight Loss Calculator uses simple and scientifically-backed formulas to estimate your Basal Metabolic Rate (BMR) and total daily calorie needs.
Step 1: Calculate BMR (Basal Metabolic Rate)
The BMR is the number of calories your body needs at rest to maintain basic bodily functions like breathing, circulation, and cell production.
For Men: BMR = 66 + (6.23 × weight in pounds) + (12.7 × height in inches) – (6.8 × age in years)
For Women: BMR = 655 + (4.35 × weight in pounds) + (4.7 × height in inches) – (4.7 × age in years)
Step 2: Adjust for Activity Level
Your daily activity affects how many calories you burn beyond resting:
- Not Active: BMR × 1.2
- Lightly Active: BMR × 1.375
- Moderately Active: BMR × 1.55
- Very Active: BMR × 1.725
Step 3: Adjust for Weight Goal
Depending on your goal:
- To Lose Weight: Subtract 500 calories per day.
- To Maintain Weight: No adjustment.
- To Gain Weight: Add 500 calories per day.
Thus, the final calorie requirement is:
Calories per day = (BMR × Activity Multiplier) – Weight Goal Adjustment
Example Calculation
Let’s go through an example:
- Weight: 180 lbs
- Height: 70 inches
- Age: 30 years
- Gender: Male
- Activity Level: Moderately Active
- Goal: Lose Weight
Step 1: Calculate BMR
BMR = 66 + (6.23 × 180) + (12.7 × 70) – (6.8 × 30)
BMR = 66 + 1121.4 + 889 – 204
BMR = 1872.4 calories/day
Step 2: Adjust for Activity
Moderately Active multiplier = 1.55
Daily calorie needs before weight goal = 1872.4 × 1.55 = 2902.22 calories/day
Step 3: Adjust for Weight Loss
To lose weight, subtract 500 calories:
Final calorie intake = 2902.22 – 500 = 2402.22 calories/day

13. What is BMR?
BMR stands for Basal Metabolic Rate — the calories your body needs to function at rest.
14. How is BMR different from calories burned during activity?
BMR is for basic functions; activities like walking and exercising burn additional calories.
