### Buying power of \$1 in 1640

This chart shows a calculation of buying power equivalence for \$1 in 1640 (price index tracking began in 1635).

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

When \$1 is equivalent to \$1 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 1640 dollars, the chart below shows how \$1 buys less over the past 2 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. This chart shows the average rate of inflation for select CPI categories between 1640 and 1642.

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

Category Avg Inflation (%) Total Inflation (%) \$1 in 1640 → 1642
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1640. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1640 to 1642

This inflation calculator uses the following inflation rate formula:

CPI in 1642CPI in 1640
×
1640 USD value
=
1642 USD value

Then plug in historical CPI values. The U.S. CPI was 9.6 in the year 1640 and 9.6 in 1642:

9.69.6
×
\$1
=
\$1

\$1 in 1640 has the same "purchasing power" or "buying power" as \$1 in 1642.

To get the total inflation rate for the 2 years between 1640 and 1642, we use the following formula:

CPI in 1642 - CPI in 1640CPI in 1640
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

9.6 - 9.69.6
×
100
=
0%

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
