Understand the Real Value of Money

A dollar in 1990 does not buy what a dollar buys today. The Inflation Adjuster uses Consumer Price Index (CPI) data to calculate how purchasing power changes over time, letting you compare prices across different years in real terms.

Enter an amount and two years, and the tool shows you the equivalent value adjusted for inflation. It also displays the cumulative inflation rate, average annual inflation, and a chart showing purchasing power decline over your selected period.

This is essential for salary negotiations, investment analysis, contract pricing, and understanding whether costs have truly risen or just kept pace with inflation.

Frequently Asked Questions

What is CPI?

The Consumer Price Index measures the average change in prices paid by consumers for a basket of goods and services. It is the standard measure used to calculate inflation.

How accurate are future projections?

Forward projections use historical average inflation rates (typically 2-3% annually). Actual future inflation may differ significantly from projections.

Why does my salary feel lower even after a raise?

If your raise was less than the inflation rate, your purchasing power actually decreased. A 3% raise with 4% inflation means a 1% real pay cut.

Does this account for specific categories?

The CPI represents overall consumer prices. Specific categories like healthcare, education, or housing may inflate at very different rates from the overall index.
