## Inflation in 1911 and its effect on dollar value

\$1 in 1910 is equivalent in purchasing power to about \$1 in 1911. The dollar had an average inflation rate of 0.00% per year between 1910 and 1911, producing a cumulative price increase of 0.00%. Purchasing power decreased by 0.00% in 1911 compared to 1910. On average, you would have to spend 0.00% more money in 1911 than in 1910 for the same item.

The inflation rate in 1910 was 4.40%. The inflation rate in 1911 was 0.00%. The 1911 inflation rate is lower compared to the average inflation rate of 3.14% per year between 1911 and 2024.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1911 was 9.50. It was 9.50 in the previous year, 1910. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

## Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1910 would be equivalent to £1.00 in 1911, an absolute change of £0.00 and a cumulative change of 0.00%.

Compare these numbers to the US's overall absolute change of \$0.00 and total percent change of 0.00%.

## Inflation by Spending Category

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 1910 and 1911.

Compare these values to the overall average of 0.00% per year:

For all these visualizations, it's important to note that not all categories may have been tracked since 1910. This table and charts use the earliest available data for each category.

## How to calculate inflation rate for \$1, 1910 to 1911

Our calculations use the following inflation rate formula to calculate the change in value between 1910 and 1911:

CPI in 1911 CPI in 1910
×
1910 USD value
=
1911 USD value

Then plug in historical CPI values. The U.S. CPI was 9.5 in the year 1910 and 9.5 in 1911:

9.59.5
×
\$1
=
\$1

\$1 in 1910 has the same "purchasing power" or "buying power" as \$1 in 1911.

To get the total inflation rate for the 1 years between 1910 and 1911, we use the following formula:

CPI in 1911 - CPI in 1910CPI in 1910
×

Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

9.5 - 9.59.5

=

## 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 1910, our investment would be nominally worth approximately \$1.00 in 1911. This is a return on investment of 0.00%, with an absolute return of \$0.00 on top of the original \$1.

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 0.00% of returns (\$0.00) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.00. You may also want to account for capital gains tax, which would take your real return down to around \$0 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 1910 to latest available data for 1911 using average monthly close price.
