Buying power of $1 in 1855

This chart shows a calculation of buying power equivalence for $1 in 1855 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $1.51 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.51 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 1855 dollars, the chart below shows how $1 is worth less over 15 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:

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 1855 and 1870.

Compare these values to the overall average of 2.77% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1855 → 1870

How to Calculate Inflation Rate for $1, 1855 to 1870

Our calculations use the following inflation rate formula to calculate the change in value between 1855 and 1870:

CPI in 1870 CPI in 1855
×
1855 USD value
=
1870 USD value

Then plug in historical CPI values. The U.S. CPI was 8.7 in the year 1855 and 13.1 in 1870:

13.18.7
×
$1
=
$1.51

$1 in 1855 has the same "purchasing power" or "buying power" as $1.51 in 1870.

To get the total inflation rate for the 15 years between 1855 and 1870, we use the following formula:

CPI in 1870 - CPI in 1855CPI in 1855
×
100
=
Cumulative inflation rate (15 years)

Plugging in the values to this equation, we get:

13.1 - 8.78.7
×
100
=
51%
