$100 in 2000 is equivalent in purchasing power to about $158.87 today, an increase of $58.87 over 21 years. The dollar had an average inflation rate of 2.23% per year between 2000 and today, producing a cumulative price increase of 58.87%.

This means that today's prices are 1.59 times higher than average prices since 2000, according to the Bureau of Labor Statistics consumer price index. A dollar today only buys 62.94% of what it could buy back then.

The 2000 inflation rate was 3.36%. The current year-over-year inflation rate (2020 to 2021) is now 5.25%^{1}.
If this number holds, $100 today will be equivalent in buying power to $105.25 next year.

This chart shows a calculation of buying power equivalence for $100 in 2000 (price index tracking began in 1635).

For example, if you started with $100, you would need to end with $158.87 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $158.87 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 2000 dollars, the chart below shows how $100 is worth less over 21 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:

San Diego, California experienced the highest rate of inflation during the 21 years between 2000 and 2021 (3.92%).

Detroit, Michigan experienced the lowest rate of inflation during the 21 years between 2000 and 2021 (1.76%).

Note that some locations showing 0% inflation may have not yet reported latest data.

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 2000 would be equivalent to £172.66 in 2021, an absolute change of £72.66 and a cumulative change of 72.66%.

In Canada, CA$100.00 in 2000 would be equivalent to CA$142.09 in 2021, an absolute change of CA$42.09 and a cumulative change of 42.09%.

Compare these numbers to the US's overall absolute change of $58.87 and total percent change of 58.87%.

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 2000 and 2021.

Compare these values to the overall average of 2.23% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $100 in 2000 → 2021 |
---|---|---|---|

Food and beverages | 2.34 | 62.40 | 162.40 |

Housing | 2.38 | 63.96 | 163.96 |

Apparel | -0.36 | -7.32 | 92.68 |

Transportation | 1.84 | 46.61 | 146.61 |

For all these visualizations, it's important to note that not all categories may have been tracked since 2000. This table and charts use the earliest available data for each category.

Our calculations use the following inflation rate formula to calculate the change in value between 2000 and today:

Then plug in historical CPI values. The U.S. CPI was 172.2 in the year 2000 and 273.567 in 2021:

$100 in 2000 has the same "purchasing power" or "buying power" as $158.87 in 2021.

To get the total inflation rate for the 21 years between 2000 and 2021, we use the following formula:

The above data describe the CPI for all items. Also of note is the **Core CPI**, which measures inflation for all items except for the more volatile categories of food and energy.
Core inflation averaged 2.00% per year between 2000 and 2021 (vs all-CPI inflation of 2.23%), for an inflation total of 51.61%.

When using the core inflation measurement, $100 in 2000 is equivalent in buying power to $151.61 in 2021, a difference of $51.61. Recall that for All Items, the converted amount is $158.87 with a difference of $58.87.

In 2000, core inflation was 2.43%.

**Chained CPI** is an alternative measurement that takes into account how consumers adjust spending for similar items.
Chained inflation averaged 1.88% per year between 2000 and 2021, a total inflation amount of 51.61%.

According to the Chained CPI measurement, $100 in 2000 is equal in buying power to $147.75 in 2021, a difference of $47.75 (versus a converted amount of $158.87/change of $58.87 for All Items).

In 2000, chained inflation was 1.99%.

The average inflation rate of 2.23% has a compounding effect between 2000 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 58.87% over 21 years.

To help put this inflation into perspective, if we had invested $100 in the S&P 500 index in 2000, our investment would be * nominally* worth approximately $471.02 in 2021. This is a return on investment of 371.02%, with an absolute return of $371.02 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 37.05% of returns ($174.53) during this period. This means the inflation-adjusted * real* return of our $100 investment is $196.49. You may also want to account for capital gains tax, which would take your real return down to around $167 for most people.

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

Nominal |
$100 | $471.02 | 371.02% |

RealInflation Adjusted |
$100 | $296.49 | 196.49% |

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 2000 to latest available data for 2021 using average monthly close price.

Politics and news often influence economic performance. Here's what was happening at the time:

- Steve Ballmer becomes CEO of Microsoft after Bill Gates steps down.
- Dot-com bubble bursts after NASDAQ Composite stock market index peaks.
- George Bush becomes President of the U.S. in a disputed election that is eventually resolved by the Supreme Court.
- Gisborne, New Zealand becomes the first city to enter the new millennium.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
