How to calculate inflation rate for $99.75 since 1901
Our calculations use the following inflation rate formula to calculate the change in value between 1901 and today:
CPI today CPI in 1901
×
1901 USD value
=
Today's value
Then plug in historical CPI values. The U.S. CPI was 8.5 in the year 1901 and 315.664 in 2024:
315.6648.5
×
$99.75
=
$3,704.41
$99.75 in 1901 has the same "purchasing power" or "buying power" as $3,704.41 in 2024.
To get the total inflation rate for the 123 years between 1901 and 2024, we use the following formula:
CPI in 2024 - CPI in 1901CPI in 1901
×
100
=
Cumulative inflation rate (123 years)
Plugging in the values to this equation, we get:
315.664 - 8.58.5

=
3,614%
Comparison to S&P 500 Index
The average inflation rate of 2.98% has a compounding effect between 1901 and 2024. As noted above, this yearly inflation rate compounds to produce an overall price difference of 3,613.69% over 123 years.
To help put this inflation into perspective, if we had invested $99.75 in the S&P 500 index in 1901, our investment would be nominally worth approximately $10,885,169.36 in 2024. This is a return on investment of 10,912,350.48%, with an absolute return of $10,885,069.61 on top of the original $99.75.
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 0.00% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $99.75 investment is $0.00. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.
| Original Amount | Final Amount | Change | |
|---|---|---|---|
| Nominal | $99.75 | $10,885,169.36 | 10,912,350.48% |
| Real Inflation Adjusted | $99.75 | $0.00 | 0.00% |
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 1901 to latest available data for 2024 using average monthly close price.
