Buying power of ¥100 in 1956

This chart shows a calculation of buying power equivalence for ¥100 in 1956 (price index tracking began in 1955).

For example, if you started with ¥100, you would need to end with ¥606.46 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When ¥100 is equivalent to ¥606.46 over time, that means that the "real value" of a single Japanese yen decreases over time. In other words, a yen will pay for fewer items at the store.

This effect explains how inflation erodes the value of a yen over time. By calculating the value in 1956 dollars, the chart below shows how ¥100 is worth less over 66 years.

According to the OECD and the World Bank, each of these JPY amounts below is equal in terms of what it could buy at the time:

To get the total inflation rate for the 66 years between 1956 and 2022, we use the following formula:

CPI in 2022 - CPI in 1956CPI in 1956
×
100
=
Cumulative inflation rate (66 years)

Plugging in the values to this equation, we get:

103.5378 - 17.072617.0726
