## Buying power of \$100,000,000 in 1877

This chart shows a calculation of buying power equivalence for \$100,000,000 in 1877 (price index tracking began in 1635).

For example, if you started with \$100,000,000, you would need to end with \$2,563,761,904.76 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100,000,000 is equivalent to \$2,563,761,904.76 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 1877 dollars, the chart below shows how \$100,000,000 is worth less over 144 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 by Country

Inflation can also vary widely by country. For comparison, in the UK £100,000,000.00 in 1877 would be equivalent to £11,958,257,092.78 in 2021, an absolute change of £11,858,257,092.78 and a cumulative change of 11,858.26%.

Compare these numbers to the US's overall absolute change of \$2,463,761,904.76 and total percent change of 2,463.76%.

## 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 1877 and 2021.

Compare these values to the overall average of 2.28% per year:

Category Avg Inflation (%) Total Inflation (%) \$100,000,000 in 1877 → 2021
Food and beverages 3.87 23,524.75 23,624,746,584.79

For all these visualizations, it's important to note that not all categories may have been tracked since 1877. This table and charts use the earliest available data for each category.

## How to Calculate Inflation Rate for \$100,000,000 since 1877

Our calculations use the following inflation rate formula to calculate the change in value between 1877 and today:

CPI today CPI in 1877
×
1877 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 10.5 in the year 1877 and 269.195 in 2021:

269.19510.5
×
\$100,000,000
=
\$2,563,761,904.76

\$100,000,000 in 1877 has the same "purchasing power" or "buying power" as \$2,563,761,904.76 in 2021.

To get the total inflation rate for the 144 years between 1877 and 2021, we use the following formula:

CPI in 2021 - CPI in 1877CPI in 1877
×
100
=
Cumulative inflation rate (144 years)

Plugging in the values to this equation, we get:

269.195 - 10.510.5
×
100
=
2,464%

## Comparison to S&P 500 Index

The average inflation rate of 2.28% has a compounding effect between 1877 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,463.76% over 144 years.

To help put this inflation into perspective, if we had invested \$100,000,000 in the S&P 500 index in 1877, our investment would be nominally worth approximately \$44,999,440,231,626.04 in 2021. This is a return on investment of 44,999,340.23%, with an absolute return of \$44,999,340,231,626.04 on top of the original \$100,000,000.

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 96.10% of returns (\$43,244,228,870,226.04) during this period. This means the inflation-adjusted real return of our \$100,000,000 investment is \$1,755,111,361,400.00. You may also want to account for capital gains tax, which would take your real return down to around \$1,491,844,657,190 for most people.

Investment in S&P 500 Index, 1877-2021
Original Amount Final Amount Change
Nominal \$100,000,000 \$44,999,440,231,626.04 44,999,340.23%
Real
\$100,000,000 \$1,755,211,361,400.00 1,755,111.36%

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 1877 to latest available data for 2021 using average monthly close price.

For more details on the S&P 500 between 1877 and 2021, see the stock market returns calculator.
