# Excel/reduce cell numbers by percent

Question
hi Jan
sorry to bother you ( hope i explain this well) i have an excel sheet as a price list and i have about 40 cells with separate prices in each of them, is it possible for me to reduce or increase those prices by "percent" just by typing that percent in a separate empty cell thanks.
regards Rick

Hi Rick,

I can think of two ways.

1. Formula:

=A1*(1+\$C\$1)

(put the percentage in cell C1)

2. Copy paste

- Put one plus the percentage in a separate cell like this: 10 percent becomes: 1.1
and copy that cell
- Select the cells that need the change, select Paste Special and choose multiply as the
operation.
