$100 in 2018 is equivalent in purchasing power to about $263.29 in 2050, an increase of $163.29 over 32 years. The dollar had an average inflation rate of 3.07% per year between 2018 and 2050, producing a cumulative price increase of 163.29%. The buying power of $100 in 2018 is predicted to be equivalent to $263.29 in 2050.

This calculation is based on future inflation assumption of 3.00% per year. Use the calculator on the left to change this prediction. Or, use the annual inflation rate calculator to view inflation in the past.

This chart shows a calculation of buying power equivalence for $100 in 2018 (price index tracking began in 1635).

For example, if you started with $100, you would need to end with $263.29 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

Future inflation is estimated at 3.00%.When $100 is equivalent to $263.29 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 2018 dollars, the chart below shows how $100 is worth less over 32 years.

This table shows the results of the inflation prediction, with base values from the Bureau of Labor Statistics:

The average inflation rate of 3.07% has a compounding effect between 2018 and 2050. As noted above, this yearly inflation rate compounds to produce an overall price difference of 163.29% over 32 years.

To help put this inflation into perspective, if we had invested $100 in the S&P 500 index in 2018, our investment would be * nominally* worth approximately $161.03 in 2050. This is a return on investment of 61.03%, with an absolute return of $61.03 on top of the original $100.

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 100.62% of returns ($162.03) during this period. This means the inflation-adjusted * real* return of our $100 investment is $-101.00. You may also want to account for capital gains tax, which would take your real return down to around $-86 for most people.

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

Nominal |
$100 | $161.03 | 61.03% |

RealInflation Adjusted |
$100 | $-1.00 | -101.00% |

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 2018 to latest available data for 2050 using average monthly close price.

For more details on the S&P 500 between 2018 and 2050, see the stock market returns calculator.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1634 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.
