Question 1

How does the inflation tracker calculate real value?

Accepted Answer

The inflation tracker calculates USD purchasing power using official U.S. CPI-U (Consumer Price Index for All Urban Consumers) annual averages from the Bureau of Labor Statistics. You enter a historical dollar amount and year, and the tool outputs the exact equivalent value in 2026 dollars.

Question 2

What years does the inflation calculator support?

Accepted Answer

The calculator supports historical inflation data from 1990 through 2026. It compares your selected past year against a 2026 baseline. The 2026 calculations incorporate current projected CPI-U data to provide accurate modern purchasing power estimates.

Question 3

How does the "What could you buy?" comparison work?

Accepted Answer

The "What could you buy?" feature contextualizes inflation by comparing physical purchasing power. It calculates exactly how many gallons of gasoline, Big Macs, or movie tickets your selected dollar amount purchased in the past versus today. The tool displays the exact quantity difference based on historical average prices.

Question 4

Where do the historical product prices come from?

Accepted Answer

The tool sources historical product prices from three primary authorities. Gasoline prices come directly from the U.S. Energy Information Administration (EIA). Big Mac pricing relies on The Economist's Big Mac Index. Movie ticket costs utilize historical averages provided by the National Association of Theatre Owners (NATO).

Question 5

Why might the result differ slightly from other inflation calculators?

Accepted Answer

Inflation results differ across calculators based on their underlying data choices. This tool specifically uses the annual average of the CPI-U series. Other calculators might use the CPI-W series, month-specific data points, or alternative base periods, resulting in slight percentage variations.

Question 6

Can I calculate inflation for currencies other than the US Dollar?

Accepted Answer

The calculator exclusively supports the U.S. Dollar (USD). It relies entirely on United States Consumer Price Index data. Applying these specific inflation rates and historical product prices to other global currencies produces inaccurate financial results.

Question 7

Is my financial data kept private?

Accepted Answer

Your financial inputs remain completely private. The inflation calculation executes entirely within your browser using a local dataset. We never send, track, or save your entered dollar amounts or selected years to any external servers.
