Cash stashed as of January 1: EUR/USD/Whatever
Inflation rate (in percentage): %



With an inflation of %...

Your initial wealth is now equivalent to (value on January 1st).
That means that you need (at today's value) in order to keep your original purchasing power.
That means that you essentially lost (at today's value) to inflation.
If you do nothing, at the end of the year your wealth will be worth (at January 1st value).
At the end of the year, you will need to have in your account in order to keep the purchasing power you had on January 1st.


Now, assuming constant inflation during the following 10 years...

In 10 years, your wealth will be worth (using the value at January 1st this year).
In 10 years, you will need to have in your account in order to keep the purchasing power you had on January 1st this year.
