## 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.

This chart shows the average rate of inflation for select CPI categories between 1918 and 2021.

Compare these values to the overall average of 2.84% per year:

Category Avg Inflation (%) Total Inflation (%) \$490 in 1918 → 2021
Food and beverages 3.90 5,067.92 25,322.79
Housing 4.18 6,673.74 33,191.33

## How to Calculate Inflation Rate for \$490, 1918 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 1918 and 2021:

CPI in 2021 CPI in 1918
×
1918 USD value
=
2021 USD value

Then plug in historical CPI values. The U.S. CPI was 15.1 in the year 1918 and 270.97016666667 in 2021:

270.9701666666715.1
×
\$490
=
\$8,793.07

\$490 in 1918 has the same "purchasing power" or "buying power" as \$8,793.07 in 2021.

To get the total inflation rate for the 103 years between 1918 and 2021, we use the following formula:

CPI in 2021 - CPI in 1918CPI in 1918
×
100
=
Cumulative inflation rate (103 years)

Plugging in the values to this equation, we get:

270.97016666667 - 15.115.1
×
100
=
1,695%

## Comparison to S&P 500 Index

The average inflation rate of 2.84% has a compounding effect between 1918 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 1,694.50% over 103 years.

To help put this inflation into perspective, if we had invested \$490 in the S&P 500 index in 1918, our investment would be nominally worth approximately \$18,950,594.80 in 2021. This is a return on investment of 3,867,368.33%, with an absolute return of \$18,950,104.80 on top of the original \$490.

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 94.43% of returns (\$17,894,559.79) during this period. This means the inflation-adjusted real return of our \$490 investment is \$1,055,545.01. You may also want to account for capital gains tax, which would take your real return down to around \$897,213 for most people.

Investment in S&P 500 Index, 1918-2021
Original Amount Final Amount Change
Nominal \$490 \$18,950,594.80 3,867,368.33%
Real
Inflation Adjusted
\$490 \$1,056,035.01 215,417.35%

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 1918 to latest available data for 2021 using average monthly close price.
