Formula Used in Weight Loss Calculation
The calculator is based on simple but effective mathematical formulas.
1. Weight to Lose Formula
This calculates how much weight you need to lose.
Wloss=Wcurrent−Wgoal
Example
If:
- Current Weight = 180 lbs
- Goal Weight = 150 lbs
Then:
Weight to Lose = 180 - 150 = 30 lbs2. Estimated Weeks Formula
This calculates how many weeks you need to reach your goal.
Weeks = \frac{W_{loss}}{Rate}}
Example
If:
- Weight to lose = 30 lbs
- Weekly loss rate = 2 lbs
Then:
Weeks = 30 ÷ 2 = 15 weeks3. Estimated Goal Date Formula
This estimates your target completion date.
Goal Date=Today+(Weeks×7 days)
Example
If today is January 1 and:
- Weeks = 15
Then:
Goal Date ≈ April 16Weight Loss Calculation Example Table
