Formula Behind Weight Loss Calculation

This calculator works on simple mathematical formulas used in fitness planning.


1. Total Weight Loss Formula

Total Loss=Current WeightGoal Weight\text{Total Loss} = \text{Current Weight} - \text{Goal Weight}Total Loss=Current Weight−Goal Weight

This calculates how many kilograms you need to lose.


2. Time (Weeks) Calculation

Weeks=Total LossWeekly Loss Rate\text{Weeks} = \frac{\text{Total Loss}}{\text{Weekly Loss Rate}}Weeks=Weekly Loss RateTotal Loss​

This estimates how many weeks you will need to reach your goal.


3. Target Date Calculation

Target Date=Start Date+(Weeks×7 days)\text{Target Date} = \text{Start Date} + (\text{Weeks} \times 7 \text{ days})Target Date=Start Date+(Weeks×7 days)

This helps you determine your expected goal completion date.


Example Calculation

Let’s understand how the calculator works with a real example.

Given Data:

  • Current Weight = 80 kg
  • Goal Weight = 65 kg
  • Weekly Loss Rate = 0.5 kg/week
  • Start Date = 1 January 2026

Step 1: Total Weight Loss

80 − 65 = 15 kg


Step 2: Estimate Weeks

15 ÷ 0.5 = 30 weeks


Step 3: Calculate Target Date

Start Date + 30 weeks ≈ End of July 2026


Final Result:

  • Total Weight Loss: 15 kg
  • Time Needed: 30 weeks
  • Target Date: Around July 2026
