## Buying power of \$100 in 1990

This chart shows a calculation of buying power equivalence for \$100 in 1990 (price index tracking began in 1635).

For example, if you started with \$100, you would need to end with \$181.34 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$181.34 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 1990 dollars, the chart below shows how \$100 is worth less over 25 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 1990 to 2015 (figures shown are purchasing power equivalents of \$100):

Seattle, Washington experienced the highest rate of inflation during the 25 years between 1990 and 2015 (3.45%).

Detroit, Michigan experienced the lowest rate of inflation during the 25 years between 1990 and 2015 (2.16%).

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 £100.00 in 1990 would be equivalent to £205.03 in 2015, an absolute change of £105.03 and a cumulative change of 105.03%.

In Canada, CA\$100.00 in 1990 would be equivalent to CA\$158.32 in 2015, an absolute change of CA\$58.32 and a cumulative change of 58.32%.

Compare these numbers to the US's overall absolute change of \$81.34 and total percent change of 81.34%.

## Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes. This chart shows the average rate of inflation for select CPI categories between 1990 and 2015.

Compare these values to the overall average of 2.41% per year:

Category Avg Inflation (%) Total Inflation (%) \$100 in 1990 → 2015
Food and beverages 2.53 86.87 186.87
Housing 2.50 85.19 185.19
Apparel 0.06 1.47 101.47
Transportation 2.03 65.18 165.18
Medical care 4.12 174.42 274.42

## How to Calculate Inflation Rate for \$100, 1990 to 2015

Our calculations use the following inflation rate formula to calculate the change in value between 1990 and 2015:

CPI in 2015 CPI in 1990
×
1990 USD value
=
2015 USD value

Then plug in historical CPI values. The U.S. CPI was 130.7 in the year 1990 and 237.017 in 2015:

237.017130.7
×
\$100
=
\$181.34

\$100 in 1990 has the same "purchasing power" or "buying power" as \$181.34 in 2015.

To get the total inflation rate for the 25 years between 1990 and 2015, we use the following formula:

CPI in 2015 - CPI in 1990CPI in 1990
×
100
=
Cumulative inflation rate (25 years)

Plugging in the values to this equation, we get:

237.017 - 130.7130.7
×
100
=
81%

## 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 2.35% per year between 1990 and 2015 (vs all-CPI inflation of 2.41%), for an inflation total of 78.83%.

When using the core inflation measurement, \$100 in 1990 is equivalent in buying power to \$178.83 in 2015, a difference of \$78.83. Recall that for All Items, the converted amount is \$181.34 with a difference of \$81.34.

In 1990, core inflation was 5.03%.

## Comparison to S&P 500 Index

The average inflation rate of 2.41% has a compounding effect between 1990 and 2015. As noted above, this yearly inflation rate compounds to produce an overall price difference of 81.34% over 25 years.

To help put this inflation into perspective, if we had invested \$100 in the S&P 500 index in 1990, our investment would be nominally worth approximately \$968.00 in 2015. This is a return on investment of 868.00%, with an absolute return of \$868.00 on top of the original \$100.

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 44.86% of returns (\$434.21) during this period. This means the inflation-adjusted real return of our \$100 investment is \$433.79. You may also want to account for capital gains tax, which would take your real return down to around \$369 for most people.

Investment in S&P 500 Index, 1990-2015
Original Amount Final Amount Change
Nominal \$100 \$968.00 868.00%
Real
\$100 \$533.79 433.79%

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 1990 to latest available data for 2015 using average monthly close price.

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

• Nelson Mandela is released having spent 27 years in South African prison.
• The Hubble Space Telescope takes its first photos from space.
• Dr Penny Jamieson, becomes the first woman to be made an Anglican Bishop, in New Zeeland
• The United States sends troops to Saudi Arabia, marking the beginning of Operation Desert Shield.
