## Buying power of ¥100 in 2019

This chart shows a calculation of buying power equivalence for ¥100 in 2019 (price index tracking began in 1955).

For example, if you started with ¥100, you would need to end with ¥108.73 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When ¥100 is equivalent to ¥108.73 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 2019 dollars, the chart below shows how ¥100 is worth less over 5 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:

## How to calculate inflation rate for ¥100 since 2019

Our calculations use the following inflation rate formula to calculate the change in value between 2019 and today:

CPI today CPI in 2019
×
2019 JPY value
=
Today's value

Then plug in historical CPI values. The Japanese CPI was 101.824 in the year 2019 and 110.71358916166263 in 2024:

110.71358916166263101.824
×
¥100
=
¥108.73

¥100 in 2019 has the same "purchasing power" or "buying power" as ¥108.73 in 2024.

To get the total inflation rate for the 5 years between 2019 and 2024, we use the following formula:

CPI in 2024 - CPI in 2019CPI in 2019
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

110.71358916166263 - 101.824101.824
×
