$100 in 2022 is worth $40.42 in 1988

Buying power of $100 in 1988

This chart shows a calculation of buying power equivalence for $100 in 1988 (price index tracking began in 1635).

For example, if you started with $100, you would need to end with $40.42 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $40.42 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 1988 dollars, the chart below shows how $100 is worth less over 34 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:

San Diego, California experienced the highest rate of inflation during the 34 years between 1988 and 2022 (3.49%).

St Louis, Missouri experienced the lowest rate of inflation during the 34 years between 1988 and 2022 (2.46%).

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 2022 would be equivalent to £33.10 in 1988, an absolute change of £-66.90 and a cumulative change of -66.90%.

In Canada, CA$100.00 in 2022 would be equivalent to CA$47.10 in 1988, an absolute change of CA$-52.90 and a cumulative change of -52.90%.

Compare these numbers to the US's overall absolute change of $-59.58 and total percent change of -59.58%.

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.

Between 1988 and 2022:

• Gas prices increased from $0.93 per gallon to $3.41
• Bread prices increased from $0.59 per loaf to $1.56
• Egg prices increased from $0.76 per carton to $1.93
• Chicken prices increased from $0.74 per per 1 lb of whole chicken to $1.62
• Electricity prices increased from $0.08 per KwH to $0.15

This chart shows the average rate of inflation for select CPI categories between 2022 and 1988.

Compare these values to the overall average of 2.70% per year:

How to calculate inflation rate for $100, 1988 to 2022

Our calculations use the following inflation rate formula to calculate the change in value between 1988 and 2022:

Then plug in historical CPI values. The U.S. CPI was 292.65583333333 in the year 2022 and 118.3 in 1988:

$100 in 2022 has the same "purchasing power" or "buying power" as $40.42 in 1988.

To get the total inflation rate for the 34 years between 1988 and 2022, we use the following formula:

Plugging in the values to this equation, we get:

Alternate Measurements of Inflation

There are multiple ways to measure inflation. Published rates of inflation will vary depending on methodology. The Consumer Price Index, used above, is the most common standard used globally.

Alternative measurements are sometimes used based on context and economic/political circumstances. Below are a few examples of alternative measurements.

Personal Consumption Expenditures (PCE) Inflation

The PCE Price Index is the U.S. Federal Reserve's preferred measure of inflation, compiled by the Bureau of Economic Analysis. It measures the change in prices of goods and services purchased by consumers.

The PCE Price Index changed by 2.23% per year on average between 2022 and 1988. The total PCE inflation between these dates was 111.63%. In 2022, PCE inflation was 3.91%.

This means that the PCE Index equates $100 in 2022 with $211.63 in 1988, a difference of $111.63. Compare this to the standard CPI measurement, which equates $100 with $40.42. The PCE measured 171.21% inflation compared to standard CPI.

For more information on the difference between PCE and CPI, see this analysis provided by the Bureau of Labor Statistics.

Core Inflation

Also of note is the Core CPI, which uses the standard CPI but omits the more volatile categories of food and energy.

Core inflation averaged 2.59% per year between 2022 and 1988 (vs all-CPI inflation of 2.70%), for an inflation total of 138.47%. In 2022, core inflation was 4.41%.

When using the core inflation measurement, $100 in 2022 is equivalent in buying power to $238.47 in 1988, a difference of $138.47. Recall that the converted amount is $40.42 when all items including food and energy are measured.
