Key Formulas Behind Cost of Living Calculators

1. Cost of Living Index (CLI) Calculation

$\text{CLI}_{location} = \sum_{i=1}^n (W_i \times C_{i,location})$

• $W_i$: Weight of expense category $i$
• $C_{i,location}$: Average cost of category $i$ in the location
• $n$: Number of expense categories

2. Income Adjustment Formula

$\text{Adjusted Income} = \text{Current Income} \times \frac{\text{CLI}_{target}}{\text{CLI}_{current}}$

This formula helps estimate the income needed in the target location to maintain the same standard of living.

3. Percentage Difference in Cost of Living

$\text{Difference \%} = \left( \frac{\text{CLI}_{target} - \text{CLI}_{current}}{\text{CLI}_{current}} \right) \times 100$
