This inflation calculator uses official records published by the U.S. Department of Labor. Inflation has averaged 0.93% per year since 1635, causing an overall price difference of 3,490.51%.

Use the form on this page to look up inflation for any year (this year's inflation is estimated based on latest monthly CPI data).

What is inflation? Inflation is a measure of how prices change over time. The U.S. Bureau of Labor Statistics (a part of the U.S. Department of Labor) selects a "basket of goods," which is a collection of many goods and services that are commonly used by consumers. Every month, the prices of these goods are measured and compared to previous prices.

Use the inflation calculator form as a starting point for answering questions that you have about the historical inflation rate in the U.S. This calculator allows you to "correct for inflation". You can also learn about inflation for the UK, Canada, Australia, and Europe.

Compared to last year's annual rate, the inflation rate in 2022 is now 7.75%^{1}. If this number holds, $100 today would be equivalent to $107.75 next year.

Every item in the Consumer Price Index "basket of goods" is categorized into spending categories. There are 8 major categories (food, housing, apparel, transportation, medical care, recreation, education, and other), and over 200 subcategories.

In the past year, the biggest mover is **Transportation**, which changed by 15.99%. This is followed by **Food and beverages** (8.77%), **Housing** (6.47%), and finally **Other goods and services** (5.70%).

Transportation has averaged 3.43% inflation since 1935. Food and beverages, Housing, and Other goods and services averaged 3.99%, 4.22%, and 4.97% respectively since they were first recorded.

In summary:

**Transportation**: 15.99% (avg. 3.43% between 1935 and 2022)**Food and beverages**: 8.77% (avg. 3.99% between 1967 and 2022)**Housing**: 6.47% (avg. 4.22% between 1967 and 2022)**Other goods and services**: 5.70% (avg. 4.97% between 1967 and 2022)

Note that category changes will appear as "-100%" if data for this year has not yet been released.

Inflation can vary widely by city, even within the United States. For obvious reasons we do not have inflation data going all the way back to the 1600s for these cities, but this excerpt showing inflation from 1990 to present day will give you an idea of how inflation varies by location.

Here's how purchasing power in some major cities changed between 1990 and 2020:

**San Diego, California**: 3.41% average rate, $100 → $255.60, cumulative change of 155.60%**Seattle, Washington**: 3.33% average rate, $100 → $258.44, cumulative change of 158.44%**Denver, Colorado**: 2.80% average rate, $100 → $216.67, cumulative change of 116.67%**San Francisco, California**: 2.78% average rate, $100 → $221.79, cumulative change of 121.79%**Atlanta, Georgia**: 2.63% average rate, $100 → $212.52, cumulative change of 112.52%**Miami-Fort Lauderdale, Florida**: 2.60% average rate, $100 → $210.49, cumulative change of 110.49%**Tampa, Florida**: 2.52% average rate, $100 → $200.77, cumulative change of 100.77%**Boston, Massachusetts**: 2.45% average rate, $100 → $202.00, cumulative change of 102.00%**New York**: 2.42% average rate, $100 → $199.92, cumulative change of 99.92%**Minneapolis-St Paul, Minnesota**: 2.37% average rate, $100 → $192.89, cumulative change of 92.89%**Houston, Texas**: 2.23% average rate, $100 → $189.62, cumulative change of 89.62%**Dallas-Fort Worth, Texas**: 2.22% average rate, $100 → $188.82, cumulative change of 88.82%**Philadelphia, Pennsylvania**: 2.19% average rate, $100 → $187.52, cumulative change of 87.52%**Chicago, Illinois**: 2.09% average rate, $100 → $182.26, cumulative change of 82.26%**Detroit, Michigan**: 2.08% average rate, $100 → $181.85, cumulative change of 81.85%**St Louis, Missouri**: 2.04% average rate, $100 → $179.57, cumulative change of 79.57%

San Diego, California experienced the highest average inflation rate of all the cities, 3.41%, in the 29 years between 1990 and 2020.

In other words, $100 in 1990 is equivalent to $255.60 in 2020 in San Diego!

St. Louis, Missouri experienced the lowest inflation rate of 2.04% during the 29 years between 1990 and 2020. $100 in 1990 is equivalent to $179.57 in 2020 in St. Louis.

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1990 would be equivalent to £225.41 in 2020, an absolute change of £125.41 and a cumulative change of 125.41%. For more, see the UK inflation calculator.

In Canada, CA$100.00 in 1990 would be equivalent to CA$166.96 in 2020, an absolute change of CA$66.96 and a cumulative change of 66.96%. This site also has a Canada inflation calculator.

Compare the rates above to the US's overall absolute change of $95.98 and total percent change of 95.98%.

We also track rates for other countries:

**Inflation in Europe**: how the Euro tracks across 37 countries**Inflation in Australia**: inflation down under**Inflation in Venezuela**: a recent example of runaway hyperinflation

The result of the Bureau of Labor Statistics' monthly "basket of goods" measurement is a single number known as the **Consumer Price Index** (CPI). This the weighted average of many changes in the price of goods and services.

Inflation is quantified as a *rate* because it is a measure of how the CPI changes over time. When you see an inflation rate, the number is based on change in CPI between two points in time.

It's important to know which dates are being compared in order to understand the inflation rate. In most cases, inflation rates are 12-month trailing. This means, for example, that the inflation rate released in March 2022 is based on a comparison to the CPI in March 2021. If the inflation rate is annual, then it's based on the year-over-year CPI.

The concept of "purchasing power" is used to compare the value of a dollar between different years. The Consumer Price Index directly measures purchasing power by keeping track of how many dollars it takes to buy common goods and services.

For example, if an apple costs $0.50 last year and $1.00 today, we can say that "the purchasing power of a dollar has decreased," because a dollar now buys you 1 apple instead of 2 (you can view actual inflation rates for apples and many other items).

Inflation is linked to purchasing power. As inflation takes place, the purchasing power of the dollar *decreases*. If deflation takes place, the purchasing power of the dollar *increases*.

This inflation calculator uses the following inflation rate formula:

2000 USD value

=

2020 USD value

Then plug in historical CPI values. The U.S. CPI was 172.2 in the year 2000 and 257.208 in 2020:

257.208172.2

$100 in 2000 has the same "purchasing power" or "buying power" as $149.37 in 2020.

To get the total inflation rate for the 20 years between 2000 and 2020, we use the following formula:

CPI in 2020 - CPI in 2000CPI in 2000

Plugging in the values to this equation, we get:

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1634 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University and from the American Antiquarian Society.
