U.S. Inflation Rate, $1 in 1980 to 2020

According to the Bureau of Labor Statistics consumer price index, today's prices in 2020 are 211.86% higher than average prices since 1980. The U.S. dollar experienced an average inflation rate of 2.88% per year during this period, meaning the real value of a dollar decreased.

In other words, $1 in 1980 is equivalent in purchasing power to about $3.12 in 2020, a difference of $2.12 over 40 years.

The 1980 inflation rate was 13.50%. The current inflation rate (2019 to 2020) is now 2.29%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 1980

This chart shows a calculation of buying power equivalence for $1 in 1980 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $3.12 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $3.12 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 1980 dollars, the chart below shows how $1 buys less over the past 40 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 City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1980 to 2020 (figures shown are purchasing power equivalents of $1):

San Francisco, California experienced the highest rate of inflation during the 40 years between 1980 and 2020 (3.40%).

Detroit, Michigan experienced the lowest rate of inflation during the 40 years between 1980 and 2020 (2.63%).

Note that some locations showing 0% inflation may have not yet reported latest data.


Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1980 would be equivalent to £4.32 in 2020, an absolute change of £3.32 and a cumulative change of 331.64%.

In Canada, CA$1.00 in 1980 would be equivalent to CA$2.95 in 2020, an absolute change of CA$1.95 and a cumulative change of 195.24%.

Compare these numbers to the US's overall absolute change of $2.12 and total percent change of 211.86%.


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 1980 and 2020.

Compare these values to the overall average of 2.88% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1980 → 2020
Food and beverages 2.83 205.85 3.06
Housing 3.09 238.32 3.38
Apparel 0.80 37.50 1.38

How to Calculate Inflation Rate for $1 since 1980

This inflation calculator uses the following inflation rate formula:

CPI in 2020CPI in 1980
×
1980 USD value
=
2020 USD value

Then plug in historical CPI values. The U.S. CPI was 82.4 in the year 1980 and 256.974 in 2020:

256.97482.4
×
$1
=
$3.12

$1 in 1980 has the same "purchasing power" or "buying power" as $3.12 in 2020.

To get the total inflation rate for the 40 years between 1980 and 2020, we use the following formula:

CPI in 2020 - CPI in 1980CPI in 1980
×
100
=
Cumulative inflation rate (40 years)

Plugging in the values to this equation, we get:

256.974 - 82.482.4
×
100
=
212%

Alternate Measurements of Inflation

The above data describe the CPI for all items. Also of note is the Core CPI, which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 3.07% per year between 1980 and 2020 (vs all-CPI inflation of 2.88%), for an inflation total of 225.82%.

When using the core inflation measurement, $1 in 1980 is equivalent in buying power to $3.26 in 2020, a difference of $2.26. Recall that for All Items, the converted amount is $3.12 with a difference of $2.12.

In 1980, core inflation was 12.42%.
