## Buying power of \$100 in 1780

This chart shows a calculation of buying power equivalence for \$100 in 1780 (price index tracking began in 1635).

For example, if you started with \$100, you would need to end with \$1,789.20 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$1,789.20 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.

## 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 1780 and 2017.

Compare these values to the overall average of 1.22% per year:

## How to Calculate Inflation Rate for \$100, 1780 to 2017

Our calculations use the following inflation rate formula to calculate the change in value between 1780 and 2017:

CPI in 2017 CPI in 1780
×
1780 USD value
=
2017 USD value

Then plug in historical CPI values. The U.S. CPI was 13.7 in the year 1780 and 245.12 in 2017:

245.1213.7
×
\$100
=
\$1,789.20

\$100 in 1780 has the same "purchasing power" or "buying power" as \$1,789.20 in 2017.

To get the total inflation rate for the 237 years between 1780 and 2017, we use the following formula:

CPI in 2017 - CPI in 1780CPI in 1780
×
100
=
Cumulative inflation rate (237 years)

Plugging in the values to this equation, we get:

245.12 - 13.713.7
×
100
=
1,689%

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