This chart shows a calculation of buying power equivalence for $100 in 2009 (price index tracking began in 1635).

For example, if you started with $100, you would need to end with $114.26 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $114.26 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 2009 dollars, the chart below shows how $100 is worth less over 8 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 Francisco, California experienced the highest rate of inflation during the 8 years between 2009 and 2017 (2.58%).

Chicago, Illinois experienced the lowest rate of inflation during the 8 years between 2009 and 2017 (1.34%).

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 2009 would be equivalent to £127.51 in 2017, an absolute change of £27.51 and a cumulative change of 27.51%.

In Canada, CA$100.00 in 2009 would be equivalent to CA$113.59 in 2017, an absolute change of CA$13.59 and a cumulative change of 13.59%.

Compare these numbers to the US's overall absolute change of $14.26 and total percent change of 14.26%.

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.

Between 2009 and 2017:

- Gas prices increased from $1.79 per gallon to $2.35
- Bread prices increased from $1.38 per loaf to $1.35
- Milk prices increased from $0.00 per gallon to $0.00
- Egg prices increased from $1.85 per carton to $1.60

This chart shows the average rate of inflation for select CPI categories between 2009 and 2017.

Compare these values to the overall average of 1.68% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $100 in 2009 → 2017 |
---|---|---|---|

Food and beverages | 1.70 | 14.47 | 114.47 |

For all these visualizations, it's important to note that not all categories may have been tracked since 2009. 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 2009 and 2017:

$100 in 2009 has the same "purchasing power" or "buying power" as $114.26 in 2017.

To get the total inflation rate for the 8 years between 2009 and 2017, 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 1.76% per year between 2009 and 2017 (vs all-CPI inflation of 1.68%), for an inflation total of 15.02%.

When using the core inflation measurement, $100 in 2009 is equivalent in buying power to $115.02 in 2017, a difference of $15.02. Recall that for All Items, the converted amount is $114.26 with a difference of $14.26.

In 2009, core inflation was 1.70%.

**Chained CPI** is an alternative measurement that takes into account how consumers adjust spending for similar items.
Chained inflation averaged 1.46% per year between 2009 and 2017, a total inflation amount of 15.02%.

According to the Chained CPI measurement, $100 in 2009 is equal in buying power to $112.26 in 2017, a difference of $12.26 (versus a converted amount of $114.26/change of $14.26 for All Items).

In 2009, chained inflation was -0.47%.

The average inflation rate of 1.68% has a compounding effect between 2009 and 2017. As noted above, this yearly inflation rate compounds to produce an overall price difference of 14.26% over 8 years.

To help put this inflation into perspective, if we had invested $100 in the S&P 500 index in 2009, our investment would be * nominally* worth approximately $388.06 in 2017. This is a return on investment of 288.06%, with an absolute return of $288.06 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 12.48% of returns ($48.42) during this period. This means the inflation-adjusted * real* return of our $100 investment is $239.65. You may also want to account for capital gains tax, which would take your real return down to around $204 for most people.

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

Nominal |
$100 | $388.06 | 288.06% |

RealInflation Adjusted |
$100 | $339.65 | 239.65% |

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 2009 to latest available data for 2017 using average monthly close price.

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

- Barack Obama is inaugurated as the 44th President of the United States.
- An arrest warrant is issued for Omar Hassan al-Bashir, Sudanese President, by International Criminal Court, for war crimes and crimes against humanity. This is the first time a sitting head of state was indicted.
- Chrysler, an automotive company, files for bankruptcy.

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.
