This chart shows a calculation of buying power equivalence for $20 in 2015 (price index tracking began in 1635).

For example, if you started with $20, you would need to end with $25.71 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $20 is equivalent to $25.71 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 2015 dollars, the chart below shows how $20 is worth less over 8 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:

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 £20.00 in 2015 would be equivalent to £26.74 in 2023, an absolute change of £6.74 and a cumulative change of 33.72%.

In Canada, CA$20.00 in 2015 would be equivalent to CA$24.81 in 2023, an absolute change of CA$4.81 and a cumulative change of 24.05%.

Compare these numbers to the US's overall absolute change of $5.71 and total percent change of 28.56%.

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 2015 and 2023:

- Gas prices increased from $2.11 per gallon to $3.45
- Bread prices increased from $1.48 per loaf to $1.89
- Egg prices increased from $2.11 per carton to $4.82
- Chicken prices increased from $1.55 per per 1 lb of whole chicken to $1.86
- Electricity prices increased from $0.14 per KwH to $0.17

This chart shows the average rate of inflation for select CPI categories between 2015 and 2023.

Compare these values to the overall average of 3.19% per year:

$20 in 2015 has the same "purchasing power" or "buying power" as $25.71 in 2023.

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 2.71% per year on average between 2015 and 2023. The total PCE inflation between these dates was 23.84%. In 2015, PCE inflation was 0.18%.

This means that the PCE Index equates $20 in 2015 with $24.77 in 2023, a difference of $4.77. Compare this to the standard CPI measurement, which equates $20 with $25.71. The PCE measured -4.72% 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 3.06% per year between 2015 and 2023 (vs all-CPI inflation of 3.19%), for an inflation total of 27.30%. In 2015, core inflation was 1.83%.

When using the core inflation measurement, $20 in 2015 is equivalent in buying power to $25.46 in 2023, a difference of $5.46. Recall that the converted amount is $25.71 when all items including food and energy are measured.

**Chained CPI** is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 2.89% per year between 2015 and 2023, a total inflation amount of 25.57%.

According to the Chained CPI measurement, $20 in 2015 is equal in buying power to $25.11 in 2023, a difference of $5.11 (versus a converted amount of $25.71/change of $5.71 for All Items).

In 2015, chained inflation was -0.12%.

The average inflation rate of 3.19% has a compounding effect between 2015 and 2023. As noted above, this yearly inflation rate compounds to produce an overall price difference of 28.56% over 8 years.

To help put this inflation into perspective, if we had invested $20 in the S&P 500 index in 2015, our investment would be * nominally* worth approximately $55.83 in 2023. This is a return on investment of 179.14%, with an absolute return of $35.83 on top of the original $20.

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 22.21% of returns ($12.40) during this period. This means the inflation-adjusted * real* return of our $20 investment is $23.43. You may also want to account for capital gains tax, which would take your real return down to around $20 for most people.

Original Amount | Final Amount | Change | |
---|---|---|---|

Nominal | $20 | $55.83 | 179.14% |

RealInflation Adjusted | $20 | $43.43 | 117.13% |

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 2015 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.
