How the Calculator Works
The calculator estimates your weight loss percentage by using the formula:
Weight Loss Percentage (%) = [(Start Weight - Current Weight) / Start Weight] × 100
Simply enter your starting weight and your current weight, and the tool will compute both the percentage of weight you've lost and the total weight lost in your preferred unit (lbs or kg).
Example Calculation:
For example, if your starting weight was 220 lbs and your current weight is 200 lbs:
- Subtract your current weight from your starting weight: 220 - 200 = 20 lbs
- Divide the difference by your starting weight: 20 / 220 = 0.09091
- Multiply by 100 to get the percentage: 0.09091 × 100 = 9.091%
Thus, you have lost approximately 9.1% of your starting weight and a total of 20 lbs.
