What 100 dollars from each year is worth today

Each year's average price level against the latest reading, August 2026. Select a year to load it into the calculator. 1920: 1,674.90 · 1950: 1,389.96 · 1970: 863.35 · 1980: 406.53 · 1990: 256.30 · 2000: 194.53 · 2010: 153.62 · 2020: 129.43.

How the calculation works

The Consumer Price Index tracks the price of a fixed basket of goods and services. Money from one date is carried to another by the ratio of the two index readings: amount × (index at the later date ÷ index at the earlier date). With the 2000 average at 172.200 and August 2026 at 334.980, 100 becomes 194.53.

The yearly figure is the steady annual rate that compounds to the same total change. It is shown only for spans of a year or more, because stretching a few months into a yearly rate exaggerates short swings.

Which price index this uses

The Consumer Price Index for All Urban Consumers, United States city average, all items, not seasonally adjusted, the same series the Bureau of Labor Statistics uses in its own calculator. Seasonal adjustment helps read one month against the next; comparing dates years apart wants the actual price level, which is the unadjusted index. The inflation readings inside the Quantamatica app use the seasonally adjusted index, so results there can differ from this page by a few tenths of a percent.

"Whole year" uses the average of that year's twelve monthly readings, the usual way to answer a question like "what was money from 1980 worth". A single month is more precise when you know the date.

What this does not capture

• Your own costs may have risen faster or slower than the average basket, for example if housing or healthcare is a large share of your spending.
• Taxes are not included. A gain that only keeps pace with prices can still be taxed as a gain.
• Figures arrive about two weeks after each month ends, so the latest month here trails the calendar.
