# U.S. inflation rate in 1988: 4.14%

### Inflation in 1988 and Its Effect on Dollar Value

Purchasing power decreased by 4.14% in 1988 compared to 1987. On average, you would have to spend 4.14% more money in 1988 than in 1987 for the same item.

In other words, \$1 in 1987 is equivalent in purchasing power to about \$1.04 in 1988.

The 1987 inflation rate was 3.65%. The inflation rate in 1988 was 4.14%. The 1988 inflation rate is higher compared to the average inflation rate of 2.53% per year between 1988 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1988 was 118.30. It was 113.60 in the previous year, 1987. 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 1987 to 1988 (figures shown are purchasing power equivalents of \$1):

Boston, Massachusetts experienced the highest rate of inflation during the 1 years between 1987 and 1988 (5.87%).

Seattle, Washington experienced the lowest rate of inflation during the 1 years between 1987 and 1988 (0.00%).

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 1987 would be equivalent to £1.05 in 1988, an absolute change of £0.05 and a cumulative change of 4.90%.

In Canada, CA\$1.00 in 1987 would be equivalent to CA\$1.04 in 1988, an absolute change of CA\$0.04 and a cumulative change of 3.88%.

Compare these numbers to the US's overall absolute change of \$0.04 and total percent change of 4.14%.

### 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 1987 and 1988.

Compare these values to the overall average of 4.14% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1987 → 1988
Food 4.13 4.13 1.04
Shelter 4.82 4.82 1.05
Energy 0.74 0.74 1.01
Apparel 4.34 4.34 1.04
New vehicles 1.87 1.87 1.02
Used cars and trucks 4.33 4.33 1.04
Transportation services 5.02 5.02 1.05
Medical care services 6.45 6.45 1.06
Medical care commodities 6.86 6.86 1.07

It's important to note that not all categories may be tracked since 1987. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1987 to 1988

This inflation calculator uses the following inflation rate formula:

CPI in 1988CPI in 1987
×
1987 USD value
=
1988 USD value

Then plug in historical CPI values. The U.S. CPI was 113.6 in the year 1987 and 118.3 in 1988:

118.3113.6
×
\$1
=
\$1.04

\$1 in 1987 has the same "purchasing power" or "buying power" as \$1.04 in 1988.

To get the total inflation rate for the 1 years between 1987 and 1988, we use the following formula:

CPI in 1988 - CPI in 1987CPI in 1987
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

118.3 - 113.6113.6
×
100
=
4%

### 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 4.41% per year between 1987 and 1988 (vs all-CPI inflation of 4.14%), for an inflation total of 4.41%.

When using the core inflation measurement, \$1 in 1987 is equivalent in buying power to \$1.04 in 1988, a difference of \$0.04. Recall that for All Items, the converted amount is \$1.04 with a difference of \$0.04.

In 1987, core inflation was 4.12%.

### 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 1987, our investment would be nominally worth approximately \$1.15 in 1988. This is a return on investment of 15.10%, with an absolute return of \$0.15.

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 3.97% of returns (\$0.01) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.15.

Investment in S&P 500 Index, 1987-1988
Original Amount Final Amount Change
Nominal \$1 \$1.15 15.10%
Real
\$1 \$0.15 14.50%

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

• New Zealand becomes the only nation to legislate against nuclear power, when their Labour government legislates against nuclear weapons and nuclear powered vessels.
• Margaret Thatcher becomes the first British PM in 160 years to win a third consecutive term in office.
• The Dow Jones stock index falls by 508.32 points, the event is later known as Black Monday.

### 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.
