### U.S. Inflation Rate, \$1 from 2015 to 2013

According to the Bureau of Labor Statistics consumer price index, prices in 2013 are 1.71% lower than average prices since 2015. The U.S. dollar experienced an average inflation rate of 0.87% per year during this period, meaning the real value of a dollar decreased.

In other words, \$1 in 2015 is equivalent in purchasing power to about \$0.98 in 2013, a difference of \$-0.02 over 2 years.

The 2013 inflation rate was 1.46%. The inflation rate in 2015 was 0.12%. The 2015 inflation rate is lower compared to the average inflation rate of 1.71% per year between 2015 and 2020.

### Buying power of \$1 in 2013

This chart shows a calculation of buying power equivalence for \$1 in 2013 (price index tracking began in 1635).

For example, if you started with \$1, you would need to end with \$0.98 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$1 is equivalent to \$0.98 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 2013 dollars, the chart below shows how \$1 buys less over the past 2 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
2013 \$1.00 1.46%
2014 \$1.02 1.62%
2015 \$1.02 0.12%
2016 \$1.03 1.26%
2017 \$1.05 2.13%
2018 \$1.08 2.49%
2019 \$1.10 1.76%
2020 \$1.11 0.90%*

### Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2015 to 2013 (figures shown are purchasing power equivalents of \$1):

San Diego, California experienced the highest rate of inflation during the 2 years between 2013 and 2015 (2.94%).

Detroit, Michigan experienced the lowest rate of inflation during the 2 years between 2013 and 2015 (-0.12%).

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 2015 would be equivalent to £0.97 in 2013, an absolute change of £-0.03 and a cumulative change of -3.26%.

In Canada, CA\$1.00 in 2015 would be equivalent to CA\$0.97 in 2013, an absolute change of CA\$-0.03 and a cumulative change of -3.00%.

Compare these numbers to the US's overall absolute change of \$-0.02 and total percent change of -1.71%.

### 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 2015 and 2013.

Compare these values to the overall average of 0.87% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 2013 → 2015
Food and beverages 2.06 4.16 1.04
Housing 2.33 4.71 1.05
Apparel -0.59 -1.18 0.99
Transportation -4.31 -8.44 0.92
Medical care 2.51 5.09 1.05
Recreation 0.29 0.59 1.01
Education and communication 0.85 1.71 1.02
Other goods and services 1.72 3.47 1.03

For all these visualizations, it's important to note that not all categories may have been tracked since 2015. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 2013 to 2015

This inflation calculator uses the following inflation rate formula:

CPI in 2013CPI in 2015
×
2015 USD value
=
2013 USD value

Then plug in historical CPI values. The U.S. CPI was 237.017 in the year 2015 and 232.957 in 2013:

232.957237.017
×
\$1
=
\$0.98

\$1 in 2015 has the same "purchasing power" or "buying power" as \$0.98 in 2013.

To get the total inflation rate for the 2 years between 2013 and 2015, we use the following formula:

CPI in 2013 - CPI in 2015CPI in 2015
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

232.957 - 237.017237.017
×
100
=
-2%

### 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 1.79% per year between 2015 and 2013 (vs all-CPI inflation of 0.87%), for an inflation total of 3.61%.

When using the core inflation measurement, \$1 in 2015 is equivalent in buying power to \$1.04 in 2013, a difference of \$0.04. Recall that for All Items, the converted amount is \$0.98 with a difference of \$-0.02.

In 2015, core inflation was 1.76%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 0.66% per year between 2015 and 2013, a total inflation amount of 3.61%.

According to the Chained CPI measurement, \$1 in 2015 is equal in buying power to \$1.01 in 2013, a difference of \$0.01 (versus a converted amount of \$0.98/change of \$-0.02 for All Items).

In 2015, chained inflation was 1.22%.

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

• Barack Obama and Raul Castro, hold the first meeting between Cuban and American leaders since the Cuban Revolution.
• The population of India reaches 1 billion (officially). The billionth baby was named Astha Arora.
• Donald Trump announces his intention to join the US presidential campaign.
• China brings an end to its one child policy, 35 years after it was first introduced.

### 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.
