Update it to how you see fit.
Value / Amount Of Item Sold
Then get the percentage.
If made on 2013, then get 95% of the number.
IF made in 2012, then get 90% of the number.
and so on.
Than subtract the original number by the percentage.
This updates once a year.
So in 2014, it equals 95% of the number. |
