The calculator will display the percentage increase and the absolute dollar amount of your cost of living increase.

Formula Used

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

Cost of Living Increase (%) = [(Current Expenses - Original Expenses) / Original Expenses] × 100 Absolute Increase = Current Expenses - Original Expenses

Where:

Current Expenses = Your current monthly expenses
Original Expenses = Your monthly expenses at the beginning of the period

Worked Example

Suppose your original monthly expenses were $2,000 and your current monthly expenses are $2,500.

Using the formula:

Cost of Living Increase (%) = [($2,500 - $2,000) / $2,000] × 100 = 25% Absolute Increase = $2,500 - $2,000 = $500

This means your cost of living has increased by 25% ($500) over the period.

Interpreting Results

The calculator provides two key pieces of information:

Percentage Increase: This shows how much your expenses have grown relative to your original amount. A 25% increase means your expenses are now 125% of what they were originally.
Absolute Increase: This shows the exact dollar amount by which your expenses have risen. For example, a $500 increase means you're spending $500 more each month than you did before.

Understanding both metrics helps you assess the true impact of inflation on your budget. A high percentage increase might indicate significant inflation, while a large absolute increase might show a more substantial financial burden.
