### U.S. Inflation Rate, \$3.20 from 2007 to 2020

According to the Bureau of Labor Statistics consumer price index, today's prices in 2020 are 24.42% higher than average prices since 2007. The U.S. dollar experienced an average inflation rate of 1.69% per year during this period, meaning the real value of a dollar decreased.

In other words, \$3.20 in 2007 is equivalent in purchasing power to about \$3.98 in 2020, a difference of \$0.78 over 13 years.

The 2007 inflation rate was 2.85%. The current inflation rate (2019 to 2020) is now 2.49%1. If this number holds, \$3.20 today will be equivalent in buying power to \$3.28 next year. The current inflation rate page gives more detail on the latest official inflation rates.

### Buying power of \$3.20 in 2007

This chart shows a calculation of buying power equivalence for \$3.20 in 2007 (price index tracking began in 1635).

For example, if you started with \$3.20, you would need to end with \$3.98 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$3.20 is equivalent to \$3.98 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 2007 dollars, the chart below shows how \$3.20 buys less over the past 13 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:

Year Dollar Value Inflation Rate
2007 \$3.20 2.85%
2008 \$3.32 3.84%
2009 \$3.31 -0.36%
2010 \$3.37 1.64%

### Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2007 to 2020 (figures shown are purchasing power equivalents of \$3.20):

San Diego, California experienced the highest rate of inflation during the 13 years between 2007 and 2020 (3.03%).

Detroit, Michigan experienced the lowest rate of inflation during the 13 years between 2007 and 2020 (1.36%).

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 £3.20 in 2007 would be equivalent to £4.47 in 2020, an absolute change of £1.27 and a cumulative change of 39.66%.

In Canada, CA\$3.20 in 2007 would be equivalent to CA\$3.90 in 2020, an absolute change of CA\$0.70 and a cumulative change of 21.79%.

Compare these numbers to the US's overall absolute change of \$0.78 and total percent change of 24.42%.

### 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 2007 and 2020.

Compare these values to the overall average of 1.69% per year:

Category Avg Inflation (%) Total Inflation (%) \$3.20 in 2007 → 2020
Food and beverages 1.92 28.05 4.10
Housing 1.96 28.73 4.12
Apparel 0.12 1.56 3.25
Transportation 0.93 12.78 3.61
Medical care 2.94 45.72 4.66
Recreation 0.71 9.61 3.51
Education and communication 1.17 16.28 3.72
Other goods and services 2.48 37.50 4.40

### How to Calculate Inflation Rate for \$3.20 since 2007

This inflation calculator uses the following inflation rate formula:

CPI in 2020CPI in 2007
×
2007 USD value
=
2020 USD value

Then plug in historical CPI values. The U.S. CPI was 207.342 in the year 2007 and 257.971 in 2020:

257.971207.342
×
\$3.20
=
\$3.98

\$3.20 in 2007 has the same "purchasing power" or "buying power" as \$3.98 in 2020.

To get the total inflation rate for the 13 years between 2007 and 2020, we use the following formula:

CPI in 2020 - CPI in 2007CPI in 2007
×
100
=
Cumulative inflation rate (13 years)

Plugging in the values to this equation, we get:

257.971 - 207.342207.342
×
100
=
24%

### 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 1.81% per year between 2007 and 2020 (vs all-CPI inflation of 1.69%), for an inflation total of 26.23%.

When using the core inflation measurement, \$3.20 in 2007 is equivalent in buying power to \$4.04 in 2020, a difference of \$0.84. Recall that for All Items, the converted amount is \$3.98 with a difference of \$0.78.

In 2007, core inflation was 2.34%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.48% per year between 2007 and 2020, a total inflation amount of 26.23%.

According to the Chained CPI measurement, \$3.20 in 2007 is equal in buying power to \$3.87 in 2020, a difference of \$0.67 (versus a converted amount of \$3.98/change of \$0.78 for All Items).

In 2007, chained inflation was 2.53%.

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

• The British Army withdraws from Northern Ireland, marking the end of, operation Banner - the longest operation in British military history.
• The South Korean President enters North Korea, crossing the Military Demarcation Line, to the second Inter-Korean Summit with the leader of North Korea.
• Bulgaria and Romania join the European Union. Aside from Irish, languages of the two countries become official EU languages, amongst 20 others.
• Slovenia becomes the 13th Eurozone country, after adopting the Euro currency.
