Subtracting values up column databases

Hello,

 

What DAX measure (or column) would be required if I wanted to count the difference in values within a column of a fact table - per year?

 

Below the subtract of 8 (2021) from 5 (2010) gives me 3.

Diff: =
VAR _previousvalue =
    CALCULATE (
        [Total coffees:],
        OFFSET ( -1, ALL ( Data[Year] ), ORDERBY ( Data[Year], ASC ) )
    )
RETURN
    IF (
        NOT ISBLANK ( _previousvalue ) && HASONEVALUE ( Data[Year] ),
        [Total coffees:] - _previousvalue
    )
