Buying power of $100 in 1705
This chart shows a calculation of buying power equivalence for $100 in 1705 (price index tracking began in 1635).
For example, if you started with $100, you would need to end with $300 in order to "adjust" for inflation (sometimes refered to as "beating inflation").
When $100 is equivalent to $300 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 1705 dollars, the chart below shows how $100 is worth less over 95 years.

How to calculate inflation rate for $100, 1705 to 1800
Our calculations use the following inflation rate formula to calculate the change in value between 1705 and 1800:
CPI in 1800 CPI in 1705
×
1705 USD value
=
1800 USD value
Then plug in historical CPI values. The U.S. CPI was 4.2 in the year 1705 and 12.6 in 1800:
12.64.2
×
$100
=
$300
$100 in 1705 has the same "purchasing power" or "buying power" as $300 in 1800.
To get the total inflation rate for the 95 years between 1705 and 1800, we use the following formula:
CPI in 1800 - CPI in 1705CPI in 1705
×
100
=
Cumulative inflation rate (95 years)
Plugging in the values to this equation, we get:
12.6 - 4.24.2
×
100
=
200%
