### U.S. Inflation Rate, \$1 from 1831 to 2020

According to the Bureau of Labor Statistics consumer price index, today's prices in 2020 are 2,873.31% higher than average prices since 1831. The U.S. dollar experienced an average inflation rate of 1.81% per year during this period, meaning the real value of a dollar decreased.

In other words, \$1 in 1831 is equivalent in purchasing power to about \$29.73 in 2020, a difference of \$28.73 over 189 years.

The 1831 inflation rate was -5.43%. The current inflation rate (2019 to 2020) is now 2.33%1. If this number holds, \$1 today will be equivalent in buying power to \$1.02 next year. The current inflation rate page gives more detail on the latest official inflation rates.

### Buying power of \$1 in 1831

This chart shows a calculation of buying power equivalence for \$1 in 1831 (price index tracking began in 1635).

For example, if you started with \$1, you would need to end with \$29.73 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$1 is equivalent to \$29.73 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1831 dollars, the chart below shows how \$1 buys less over the past 189 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1831 would be equivalent to £104.43 in 2020, an absolute change of £103.43 and a cumulative change of 10,342.60%.

Compare these numbers to the US's overall absolute change of \$28.73 and total percent change of 2,873.31%.

### Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1831 and 2020.

Compare these values to the overall average of 1.81% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1831 → 2020
Food and beverages 3.86 128,960.42 1,290.60
Housing 4.18 230,612.33 2,307.12

### How to Calculate Inflation Rate for \$1 since 1831

This inflation calculator uses the following inflation rate formula:

CPI in 2020CPI in 1831
×
1831 USD value
=
2020 USD value

Then plug in historical CPI values. The U.S. CPI was 8.7 in the year 1831 and 258.678 in 2020:

258.6788.7
×
\$1
=
\$29.73

\$1 in 1831 has the same "purchasing power" or "buying power" as \$29.73 in 2020.

To get the total inflation rate for the 189 years between 1831 and 2020, we use the following formula:

CPI in 2020 - CPI in 1831CPI in 1831
×
100
=
Cumulative inflation rate (189 years)

Plugging in the values to this equation, we get:

258.678 - 8.78.7
×
100
=
2,873%

Politics and news often influence economic performance. Here's what was happening at the time:

• Ioannis Kapodistrias, first Head of State of modern Greece, is assassinated.
• Ecuador and Venezuela separate from Greater Colombia
• The Bosnian rebellion against Turkey marks the beginning of Great Bosnian uprising.

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
