Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2013 to 2018 (figures shown are purchasing power equivalents of $1):

San Diego, California experienced the highest rate of inflation during the 5 years between 2013 and 2018 (4.14%).

Philadelphia, Pennsylvania experienced the lowest rate of inflation during the 5 years between 2013 and 2018 (0.89%).

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 2013 would be equivalent to £1.12 in 2018, an absolute change of £0.12 and a cumulative change of 11.64%.

In Canada, CA$1.00 in 2013 would be equivalent to CA$1.07 in 2018, an absolute change of CA$0.07 and a cumulative change of 6.60%.

Compare these numbers to the US's overall absolute change of $0.08 and total percent change of 7.79%.


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 2013 and 2018.

Compare these values to the overall average of 1.51% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 2013 → 2018
Food and beverages 1.35 6.92 1.07
Housing 2.60 13.69 1.14
Apparel -0.28 -1.38 0.99
Transportation -0.63 -3.10 0.97
Medical care 2.66 14.02 1.14
Recreation 0.65 3.31 1.03
Education and communication 0.13 0.66 1.01
Other goods and services 1.98 10.30 1.10

How to Calculate Inflation Rate for $1, 2013 to 2018

This inflation calculator uses the following inflation rate formula:

CPI in 2018CPI in 2013
×
2013 USD value
=
2018 USD value

Then plug in historical CPI values. The U.S. CPI was 232.957 in the year 2013 and 251.10683333333 in 2018:

251.10683333333232.957
×
$1
=
$1.08

$1 in 2013 has the same "purchasing power" or "buying power" as $1.08 in 2018.

To get the total inflation rate for the 5 years between 2013 and 2018, we use the following formula:

CPI in 2018 - CPI in 2013CPI in 2013
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

251.10683333333 - 232.957232.957
×
100
=
8%

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 1.95% per year between 2013 and 2018 (vs all-CPI inflation of 1.51%), for an inflation total of 10.16%.

When using the core inflation measurement, $1 in 2013 is equivalent in buying power to $1.10 in 2018, a difference of $0.10. Recall that for All Items, the converted amount is $1.08 with a difference of $0.08.

In 2013, 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 1.21% per year between 2013 and 2018, a total inflation amount of 10.16%.

According to the Chained CPI measurement, $1 in 2013 is equal in buying power to $1.06 in 2018, a difference of $0.06 (versus a converted amount of $1.08/change of $0.08 for All Items).

In 2013, chained inflation was 1.22%.


Comparison to S&P 500 Index

The average inflation rate of 1.51% has a compounding effect between 2013 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 7.79% over 5 years.

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 2013, our investment would be nominally worth approximately $1.98 in 2018. This is a return on investment of 98.29%, with an absolute return of $0.98 on top of the original $1.

These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.

The compounding effect of inflation would account for 7.23% of returns ($0.14) during this period. This means the inflation-adjusted real return of our $1 investment is $0.84. You may also want to account for capital gains tax, which would take your real return down to around $1 for most people.

Investment in S&P 500 Index, 2013-2018
Original Amount Final Amount Change
Nominal $1 $1.98 98.29%
Real
Inflation Adjusted
$1 $1.84 83.95%

Information displayed above may differ slightly from other S&P 500 calculators. Minor discrepancies can occur because we use the latest CPI data for inflation, annualized inflation numbers for previous years, and we compute S&P price and dividends from January of 2013 to latest available data for 2018.
