# U.S. inflation rate in 1999: 2.21%

### Inflation in 1999 and Its Effect on Dollar Value

Purchasing power decreased by 2.21% in 1999 compared to 1998. On average, you would have to spend 2.21% more money in 1999 than in 1998 for the same item.

In other words, \$1 in 1998 is equivalent in purchasing power to about \$1.02 in 1999.

The 1998 inflation rate was 1.56%. The inflation rate in 1999 was 2.21%. The 1999 inflation rate is higher compared to the average inflation rate of 2.19% per year between 1999 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1999 was 166.60. It was 163.00 in the previous year, 1998. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

### Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1998 to 1999 (figures shown are purchasing power equivalents of \$1):

San Diego, California experienced the highest rate of inflation during the 1 years between 1998 and 1999 (6.56%).

Miami-Fort Lauderdale, Florida experienced the lowest rate of inflation during the 1 years between 1998 and 1999 (1.15%).

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 1998 would be equivalent to £1.02 in 1999, an absolute change of £0.02 and a cumulative change of 1.54%.

In Canada, CA\$1.00 in 1998 would be equivalent to CA\$1.03 in 1999, an absolute change of CA\$0.03 and a cumulative change of 2.63%.

Compare these numbers to the US's overall absolute change of \$0.02 and total percent change of 2.21%.

### 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 1998 and 1999.

Compare these values to the overall average of 2.21% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1998 → 1999
Food 2.13 2.13 1.02
Shelter 2.83 2.83 1.03
Energy 3.65 3.65 1.04
Apparel -1.30 -1.30 0.99
New vehicles -0.40 -0.40 1.00
Used cars and trucks 0.95 0.95 1.01
Transportation services 1.49 1.49 1.01
Medical care services 3.35 3.35 1.03
Medical care commodities 4.00 4.00 1.04

It's important to note that not all categories may be tracked since 1998. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1998 to 1999

This inflation calculator uses the following inflation rate formula:

CPI in 1999CPI in 1998
×
1998 USD value
=
1999 USD value

Then plug in historical CPI values. The U.S. CPI was 163 in the year 1998 and 166.6 in 1999:

166.6163
×
\$1
=
\$1.02

\$1 in 1998 has the same "purchasing power" or "buying power" as \$1.02 in 1999.

To get the total inflation rate for the 1 years between 1998 and 1999, we use the following formula:

CPI in 1999 - CPI in 1998CPI in 1998
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

166.6 - 163163
×
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 2.08% per year between 1998 and 1999 (vs all-CPI inflation of 2.21%), for an inflation total of 2.08%.

When using the core inflation measurement, \$1 in 1998 is equivalent in buying power to \$1.02 in 1999, a difference of \$0.02. Recall that for All Items, the converted amount is \$1.02 with a difference of \$0.02.

In 1998, core inflation was 2.29%.

### Comparison to S&P 500 Index

To help put this inflation into perspective, if we had invested \$1 in the S&P 500 index in 1998, our investment would be nominally worth approximately \$1.52 in 1999. This is a return on investment of 51.99%, with an absolute return of \$0.52.

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 2.16% of returns (\$0.01) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.51.

Investment in S&P 500 Index, 1998-1999
Original Amount Final Amount Change
Nominal \$1 \$1.52 51.99%
Real
\$1 \$0.51 50.87%

### News headlines from 1998

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

• Osama Bin Laden declares a Jihad against Jews and Crusaders.
• The Good Friday Agreement is accepted in a referendum in Northern Ireland.
• President of the US Bill Clinton admits that he had an "improper physical relationship" with an intern and then denied it in the same day. The event has come to be known as the Monica Lewinsky scandal.

### 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.
