Why a yen today is worth only 19% of a yen in 1961

Updated: November 12, 2020

According to the World Bank consumer price index for Japan, today's prices in 2020 are 430.21% higher than average prices since 1961. This means that a yen today only buys 18.86% of what it could buy in 1961. The Japanese Yen experienced an average inflation rate of 2.87% per year during this period, causing the real value of a yen to decrease.

In other words, ¥100 in 1961 is equivalent in purchasing power to about ¥530.21 in 2020, a difference of ¥430.21 over 59 years. This inflation data is collected by the World Bank and is specific to Japan.

The 1961 inflation rate was 5.37%. The current year-over-year inflation rate (2019 to 2020) is now 0.48%1. If this number holds, ¥100 today will be equivalent in buying power to ¥100.48 next year.

Buying power of ¥100 in 1961

This chart shows a calculation of buying power equivalence for ¥100 in 1961 (price index tracking began in 1960).

For example, if you started with ¥100, you would need to end with ¥530.21 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When ¥100 is equivalent to ¥530.21 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 1961 dollars, the chart below shows how ¥100 is worth less over 59 years.

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

How to Calculate Inflation Rate for ¥100 since 1961

Our calculations use the following inflation rate formula to calculate the change in value between 1961 and today:

CPI today CPI in 1961
×
1961 JPY value
=
Today's value

Then plug in historical CPI values. The Japanese CPI was 19.9894396961 in the year 1961 and 105.98529435141579 in 2020:

105.9852943514157919.9894396961
×
¥100
=
¥530.21

¥100 in 1961 has the same "purchasing power" or "buying power" as ¥530.21 in 2020.

To get the total inflation rate for the 59 years between 1961 and 2020, we use the following formula:

CPI in 2020 - CPI in 1961CPI in 1961
×
100
=
Cumulative inflation rate (59 years)

Plugging in the values to this equation, we get:

105.98529435141579 - 19.989439696119.9894396961
×
