Buying power of $1 in 1913
This chart shows a calculation of buying power equivalence for $1 in 1913 (price index tracking began in 1635).
For example, if you started with $1, you would need to end with $25.38 in order to "adjust" for inflation (sometimes refered to as "beating inflation").
When $1 is equivalent to $25.38 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 1913 dollars, the chart below shows how $1 is worth less over 105 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 £1.00 in 1913 would be equivalent to £112.65 in 2018, an absolute change of £111.65 and a cumulative change of 11,164.51%.
Compare these numbers to the US's overall absolute change of $24.38 and total percent change of 2,437.68%.
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 1913 and 2018.
Compare these values to the overall average of 3.13% per year:
| Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1913 → 2018 |

How to calculate inflation rate for $1, 1913 to 2018
Our calculations use the following inflation rate formula to calculate the change in value between 1913 and 2018:
CPI in 2018 CPI in 1913
×
1913 USD value
=
2018 USD value
Then plug in historical CPI values. The U.S. CPI was 9.9 in the year 1913 and 251.23 in 2018:
251.239.9
×
$1
=
$25.38
$1 in 1913 has the same "purchasing power" or "buying power" as $25.38 in 2018.
To get the total inflation rate for the 105 years between 1913 and 2018, we use the following formula:
CPI in 2018 - CPI in 1913CPI in 1913
×
100
=
Cumulative inflation rate (105 years)
Plugging in the values to this equation, we get:
251.23 - 9.99.9
×
100
=
2,438%
Comparison to S&P 500 Index
The average inflation rate of 3.13% has a compounding effect between 1913 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,437.68% over 105 years.
To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1913, our investment would be nominally worth approximately $20,781.61 in 2018. This is a return on investment of 2,078,060.73%, with an absolute return of $20,780.61 on top of the original $1.
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 96.06% of returns ($19,962.68) during this period. This means the inflation-adjusted real return of our $1 investment is $817.92. You may also want to account for capital gains tax, which would take your real return down to around $695 for most people.
| Original Amount | Final Amount | Change | |
|---|---|---|---|
| Nominal | $1 | $20,781.61 | 2,078,060.73% |
| Real Inflation Adjusted | $1 | $818.92 | 81,792.26% |
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 1913 to latest available data for 2018 using average monthly close price.
