Buying power of $1 in 1785

This chart shows a calculation of buying power equivalence for $1 in 1785 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $26.67 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $26.67 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 1785 dollars, the chart below shows how $1 buys less over the past 235 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:

How to Calculate Inflation Rate for $1 since 1785

This inflation calculator uses the following inflation rate formula:

CPI in 2020CPI in 1785
×
1785 USD value
=
2020 USD value

Then plug in historical CPI values. The U.S. CPI was 9.7 in the year 1785 and 258.678 in 2020:

258.6789.7
×
$1
=
$26.67

$1 in 1785 has the same "purchasing power" or "buying power" as $26.67 in 2020.

To get the total inflation rate for the 235 years between 1785 and 2020, we use the following formula:

CPI in 2020 - CPI in 1785CPI in 1785
×
100
=
Cumulative inflation rate (235 years)

Plugging in the values to this equation, we get:

258.678 - 9.79.7
×
100
=
2,567%
