How the Percentage of Weight Loss Calculator Works
The calculator uses two key inputs:
- Starting Weight – The weight at the beginning of your weight loss journey.
- Current Weight – Your weight at the time of calculation.
Using these values, the calculator applies a simple formula to determine the weight loss percentage, providing instant feedback on your progress.
Formula Used
The formula for calculating percentage of weight loss is:
Percentage of Weight Loss (%) = ((Starting Weight – Current Weight) ÷ Starting Weight) × 100
Where:
- Starting Weight is your initial weight
- Current Weight is your weight after some time
This formula gives the proportion of weight lost relative to your starting weight, expressed as a percentage.
How to Use the Percentage of Weight Loss Calculator
- Enter Your Starting Weight – Input the weight at the beginning of your journey.
- Enter Your Current Weight – Input your present weight.
- Click Calculate – The calculator will provide:
- Weight lost in absolute terms (kg or lbs)
- Percentage of weight lost (%)
- Analyze Results – Use this percentage to monitor progress, set goals, and stay motivated.
Example Calculation
Example: Tracking Weight Loss
- Starting Weight: 180 lbs
- Current Weight: 165 lbs
Step 1: Calculate Weight Loss
Weight Lost = 180 – 165 = 15 lbs
Step 2: Calculate Percentage of Weight Loss
Percentage = (15 ÷ 180) × 100 ≈ 8.33%
The individual has lost 15 lbs, which is approximately 8.33% of their starting weight.
