Frequently Asked Questions
What is CPI?
The Consumer Price Index (CPI) measures the average change in prices over time for a basket of goods and services. It's the most widely used measure of inflation.
How accurate is this calculator?
We use official historical CPI data. While accurate for general comparisons, individual costs may vary based on specific purchases, location, and lifestyle.
Why does $100 from 1970 seem so valuable?
Due to cumulative inflation over decades, the same amount of money bought much more in the past. This is why wages and prices have increased over time.
What currencies are supported?
This calculator supports US Dollar (using BLS CPI data from 1913) and Turkish Lira (using TUIK CPI data from 2003). More currencies may be added in the future.
What is purchasing power?
Purchasing power refers to how much goods and services your money can buy. When inflation rises, your purchasing power decreases because prices go up.
