How to Use This Calculator

To calculate the cost of living increase from 2018 to today:

Enter the amount you had in 2018 in the "Amount in 2018" field.
Select the appropriate inflation rate from the dropdown menu.
Click the "Calculate" button to see the adjusted amount for today.

The calculator will display the equivalent amount in today's dollars, showing both the raw value and the percentage increase.

Formula and Assumptions

The calculation uses the following formula:

Adjusted Amount = Amount in 2018 × (1 + Inflation Rate)^(Years)

Where:

Amount in 2018 - The original amount you had in 2018
Inflation Rate - The average annual inflation rate for the period
Years - The number of years from 2018 to today (2023)

Note: The calculator uses the average annual inflation rate for the period. Actual inflation rates may vary by category and location.

Worked Example

Suppose you had $1,000 in 2018 and the average inflation rate was 2% per year. Here's how the calculation works:

Adjusted Amount = $1,000 × (1 + 0.02)^5 Adjusted Amount = $1,000 × 1.10408 Adjusted Amount = $1,104.08

This means $1,000 in 2018 would be equivalent to $1,104.08 today, representing a 10.41% increase.

Interpreting Results

The calculator provides two key pieces of information:

Adjusted Amount - The equivalent value of your 2018 amount in today's dollars.
Percentage Increase - The percentage by which your amount has increased due to inflation.

Use these results to understand how inflation has affected your purchasing power. A higher percentage increase may indicate that your cost of living has risen significantly, while a lower percentage suggests more stable prices.
