The calculator will provide a cost of living index that compares your expenses to the national average. A higher index means your living costs are higher than average.

Formula Used

The cost of living index is calculated using the following formula:

Cost of Living Index = (Your Monthly Expenses / National Average Monthly Expenses) × 100

Where:

Your Monthly Expenses - Sum of your housing, food, transportation, and other expenses
National Average Monthly Expenses - Average expenses for the selected location

This formula provides a percentage that indicates how your living costs compare to the national average.

Interpreting Results

The cost of living index helps you understand where your expenses stand relative to the national average. Here's how to interpret the results:

Index < 100 - Your living costs are below the national average.
Index = 100 - Your living costs match the national average.
Index > 100 - Your living costs are above the national average.

Note: A cost of living index above 100 doesn't necessarily mean you're spending too much. It simply indicates that your expenses are higher than the national average.

Worked Example

Let's say you live in a city where the national average monthly expenses are $3,000. Your monthly expenses are $3,600. Here's how to calculate your cost of living index:

Cost of Living Index = ($3,600 / $3,000) × 100 = 120

Your cost of living index is 120, which means your living costs are 20% higher than the national average.
