## The U.S. dollar has lost 28% its value since 2009

Updated: August 10, 2022

Updated: August 10, 2022

$100 in 2009 is equivalent in purchasing power to about $138.10 today, an increase of $38.10 over 13 years. The dollar had an average inflation rate of 2.51% per year between 2009 and today, producing a cumulative price increase of 38.10%.

This means that today’s prices are 1.38 times higher than average prices since 2009, according to the Bureau of Labor Statistics consumer price index. A dollar today only buys 72.411% of what it could buy back then.

The inflation rate in 2009 was -0.36%. The current inflation rate compared to last year is now 8.52%. If this number holds, $100 today will be equivalent in buying power to $108.52 next year. The current inflation rate page gives more detail on the latest inflation rates.

## Buying power of $100 in 2009

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 $138.10 in order to “adjust” for inflation (sometimes refered to as “beating inflation”).

When $100 is equivalent to $138.10 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 13 years.

## How to calculate inflation rate for $100 since 2009

Our calculations use the following inflation rate formula to calculate the change in value between 2009 and today:

CPI today

CPI in 2009

×

2009 USD value

=

Today’s value

Then plug in historical CPI values. The U.S. CPI was 214.537 in the year 2009 and 296.276 in 2022:

**$138.10**

$100 in 2009 has the same “purchasing power” or “buying power” as $138.10 in 2022.

To get the total inflation rate for the 13 years between 2009 and 2022, we use the following formula:

CPI in 2022 – CPI in 2009

CPI in 2009

**Cumulative inflation rate (13 years)**

Plugging in the values to this equation, we get:

**38%**

## Alternate Measurements of Inflation

There are multiple ways to measure inflation. Published rates of inflation will vary depending on methodology. The Consumer Price Index, used above, is the most common standard used globally.

Alternative measurements are sometimes used based on context and economic/political circumstances. Below are a few examples of alternative measurements.

### Personal Consumption Expenditures (PCE) Inflation

The PCE Price Index is the U.S. Federal Reserve’s preferred measure of inflation, compiled by the Bureau of Economic Analysis. It measures the change in prices of goods and services purchased by consumers.

The PCE Price Index changed by 1.98% per year on average between 2009 and 2022. The total PCE inflation between these dates was 29.09%. In 2009, PCE inflation was -0.28%.

This means that the PCE Index equates $100 in 2009 with $129.09 in 2022, a difference of $29.09. Compare this to the standard CPI measurement, which equates $100 with $138.10. The PCE measured -9.01% inflation compared to standard CPI.

For more information on the difference between PCE and CPI, see this analysis provided by the Bureau of Labor Statistics.

### Core Inflation

Also of note is the **Core CPI**, which uses the standard CPI but omits the more volatile categories of food and energy.

Core inflation averaged 2.20% per year between 2009 and 2022 (vs all-CPI inflation of 2.51%), for an inflation total of 32.74%. In 2009, core inflation was 1.70%.

When using the core inflation measurement, $100 in 2009 is equivalent in buying power to $132.74 in 2022, a difference of $32.74. Recall that the converted amount is $138.10 when all items including food and energy are measured.

### Chained Inflation

**Chained CPI** is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 2.07% per year between 2009 and 2022, a total inflation amount of 30.58%.

According to the Chained CPI measurement, $100 in 2009 is equal in buying power to $130.58 in 2022, a difference of $30.58 (versus a converted amount of $138.10/change of $38.10 for All Items).

In 2009, chained inflation was -0.47%.

## Comparison to S&P 500 Index

The average inflation rate of 2.51% has a compounding effect between 2009 and 2022. As noted above, this yearly inflation rate compounds to produce an overall price difference of 38.10% over 13 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 $575.72 in 2022. This is a return on investment of 475.72%, with an absolute return of $475.72 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 27.59% of returns ($158.83) during this period. This means the inflation-adjusted real return of our $100 investment is $316.88. You may also want to account for capital gains tax, which would take your real return down to around $269 for most people.

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 2022 using average monthly close price.
