Inflation in 2012 and Its Effect on Dollar Value

Purchasing power decreased by 2.07% in 2012 compared to 2011. On average, you would have to spend 2.07% more money in 2012 than in 2011 for the same item.

In other words, $1 in 2011 is equivalent in purchasing power to about $1.02 in 2012.

The 2011 inflation rate was 3.16%. The inflation rate in 2012 was 2.07%. The 2012 inflation rate is higher compared to the average inflation rate of 1.54% per year between 2012 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 2012 was 229.59. It was 224.94 in the previous year, 2011. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2011 to 2012 (figures shown are purchasing power equivalents of $1):

San Francisco, California experienced the highest rate of inflation during the 1 years between 2011 and 2012 (2.71%).

Chicago, Illinois experienced the lowest rate of inflation during the 1 years between 2011 and 2012 (1.52%).

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

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 2011 would be equivalent to £1.03 in 2012, an absolute change of £0.03 and a cumulative change of 3.21%.

In Canada, CA$1.00 in 2011 would be equivalent to CA$1.01 in 2012, an absolute change of CA$0.01 and a cumulative change of 0.83%.

Compare these numbers to the US's overall absolute change of $0.02 and total percent change of 2.07%.

Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 2011 and 2012.

Compare these values to the overall average of 2.07% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 2011 → 2012
Food 2.61 2.61 1.03
Shelter 2.16 2.16 1.02
Energy 0.93 0.93 1.01
Apparel 3.40 3.40 1.03
New vehicles 1.66 1.66 1.02
Used cars and trucks 0.89 0.89 1.01
Transportation services 1.81 1.81 1.02
Medical care services 3.90 3.90 1.04
Medical care commodities 2.94 2.94 1.03

It's important to note that not all categories may be tracked since 2011. This table and visualization use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 2011 to 2012

This inflation calculator uses the following inflation rate formula:

CPI in 2012CPI in 2011
2011 USD value
2012 USD value

Then plug in historical CPI values. The U.S. CPI was 224.939 in the year 2011 and 229.594 in 2012:


$1 in 2011 has the same "purchasing power" or "buying power" as $1.02 in 2012.

To get the total inflation rate for the 1 years between 2011 and 2012, we use the following formula:

CPI in 2012 - CPI in 2011CPI in 2011
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

229.594 - 224.939224.939

Alternate Measurements of Inflation

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 2.11% per year between 2011 and 2012 (vs all-CPI inflation of 2.07%), for an inflation total of 2.11%.

When using the core inflation measurement, $1 in 2011 is equivalent in buying power to $1.02 in 2012, a difference of $0.02. Recall that for All Items, the converted amount is $1.02 with a difference of $0.02.

In 2011, core inflation was 1.66%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.95% per year between 2011 and 2012, a total inflation amount of 2.11%.

According to the Chained CPI measurement, $1 in 2011 is equal in buying power to $1.02 in 2012, a difference of $0.02 (versus a converted amount of $1.02/change of $0.02 for All Items).

In 2011, chained inflation was 3.06%.

Comparison to S&P 500 Index

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 2011, our investment would be nominally worth approximately $1.20 in 2012. This is a return on investment of 20.12%, with an absolute return of $0.20.

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 2.03% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $1 investment is $0.20.

Investment in S&P 500 Index, 2011-2012
Original Amount Final Amount Change
Nominal $1 $1.20 20.12%
Inflation Adjusted
$1 $0.20 19.71%
