U.S. inflation rate in 1912: 2.11%

Inflation in 1912 and Its Effect on Dollar Value

Purchasing power decreased by 2.11% in 1912 compared to 1911. On average, you would have to spend 2.11% more money in 1912 than in 1911 for the same item.

In other words, \$1 in 1911 is equivalent in purchasing power to about \$1.02 in 1912.

The 1911 inflation rate was 0.00%. The inflation rate in 1912 was 2.11%. The 1912 inflation rate is lower compared to the average inflation rate of 3.11% per year between 1912 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1912 was 9.70. It was 9.50 in the previous year, 1911. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

 Average inflation rate 2.11% Converted amount (\$1 base) \$1.02 Price difference (\$1 base) \$0.02 CPI in 1911 9.500 CPI in 1912 9.700 Inflation in 1911 0.00% Inflation in 1912 2.11%

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1911 would be equivalent to £1.03 in 1912, an absolute change of £0.03 and a cumulative change of 3.13%.

Compare these numbers to the US's overall absolute change of \$0.02 and total percent change of 2.11%.

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 1911 and 1912.

Compare these values to the overall average of 2.11% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1911 → 1912
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 0.00 0.00 1.00
Medical care commodities 0.00 0.00 1.00

It's important to note that not all categories may be tracked since 1911. This table and visualization use the earliest available data for each category.

How to Calculate Inflation Rate for \$1, 1911 to 1912

This inflation calculator uses the following inflation rate formula:

CPI in 1912CPI in 1911
×
1911 USD value
=
1912 USD value

Then plug in historical CPI values. The U.S. CPI was 9.5 in the year 1911 and 9.7 in 1912:

9.79.5
×
\$1
=
\$1.02

\$1 in 1911 has the same "purchasing power" or "buying power" as \$1.02 in 1912.

To get the total inflation rate for the 1 years between 1911 and 1912, we use the following formula:

CPI in 1912 - CPI in 1911CPI in 1911
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

9.7 - 9.59.5
×
100
=
2%

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 1911, our investment would be nominally worth approximately \$1.11 in 1912. This is a return on investment of 10.94%, with an absolute return of \$0.11.

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 2.06% of returns (\$0.00) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.11.

Original Amount Final Amount Change
Nominal \$1 \$1.11 10.94%
Real
\$1 \$0.11 10.72%

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

• Vicenzo Perugia steals Leonardo da Vinci's masterpiece, the Mona Lisa. It was recovered in Florence in 1913.
