This chart shows a calculation of buying power equivalence for $10 in 1991 (price index tracking began in 1635).
For example, if you started with $10, you would need to end with $22.37 in order to "adjust" for inflation (sometimes refered to as "beating inflation").
When $10 is equivalent to $22.37 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 1991 dollars, the chart below shows how $10 is worth less over 32 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 can vary widely by city, even within the United States. Here's how some cities fared in 1991 to 2023 (figures shown are purchasing power equivalents of $10):
San Diego, California experienced the highest rate of inflation during the 32 years between 1991 and 2023 (3.70%).
Chicago, Illinois experienced the lowest rate of inflation during the 32 years between 1991 and 2023 (2.29%).
Note that some locations showing 0% inflation may have not yet reported latest data.
Inflation can also vary widely by country. For comparison, in the UK £10.00 in 1991 would be equivalent to £25.90 in 2023, an absolute change of £15.90 and a cumulative change of 158.96%.
In Canada, CA$10.00 in 1991 would be equivalent to CA$18.97 in 2023, an absolute change of CA$8.97 and a cumulative change of 89.69%.
Compare these numbers to the US's overall absolute change of $12.37 and total percent change of 123.72%.
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 1991 and 2023:
This chart shows the average rate of inflation for select CPI categories between 1991 and 2023.
Compare these values to the overall average of 2.55% per year:

---|---|---|---|
Food and beverages | 2.70 | 134.29 | 23.43 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1991. This table and charts use the earliest available data for each category.
Our calculations use the following inflation rate formula to calculate the change in value between 1991 and 2023:
Then plug in historical CPI values. The U.S. CPI was 136.2 in the year 1991 and 304.70216666667 in 2023:
$10 in 1991 has the same "purchasing power" or "buying power" as $22.37 in 2023.
To get the total inflation rate for the 32 years between 1991 and 2023, we use the following formula:
Plugging in the values to this equation, we get:
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.
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 2.11% per year on average between 1991 and 2023. The total PCE inflation between these dates was 95.05%. In 1991, PCE inflation was 3.34%.
This means that the PCE Index equates $10 in 1991 with $19.51 in 2023, a difference of $9.51. Compare this to the standard CPI measurement, which equates $10 with $22.37. The PCE measured -28.66% 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.
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 2.45% per year between 1991 and 2023 (vs all-CPI inflation of 2.55%), for an inflation total of 117.00%. In 1991, core inflation was 4.91%.
When using the core inflation measurement, $10 in 1991 is equivalent in buying power to $21.70 in 2023, a difference of $11.70. Recall that the converted amount is $22.37 when all items including food and energy are measured.
The average inflation rate of 2.55% has a compounding effect between 1991 and 2023. As noted above, this yearly inflation rate compounds to produce an overall price difference of 123.72% over 32 years.
To help put this inflation into perspective, if we had invested $10 in the S&P 500 index in 1991, our investment would be nominally worth approximately $282.28 in 2023. This is a return on investment of 2,722.81%, with an absolute return of $272.28 on top of the original $10.
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 55.30% of returns ($156.10) during this period. This means the inflation-adjusted real return of our $10 investment is $116.18. You may also want to account for capital gains tax, which would take your real return down to around $99 for most people.
Original Amount | Final Amount | Change | |
---|---|---|---|
Nominal | $10 | $282.28 | 2,722.81% |
Real Inflation Adjusted | $10 | $126.18 | 1,161.78% |
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 1991 to latest available data for 2023 using average monthly close price.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Price index data from 1774 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University and from the American Antiquarian Society. Price index data from 1634 to 1773 is from the American Antiquarian Society, using British pound equivalents.
