increase the value of a cell by a percentage

[Guest]

How do i increase the value of a cell by a percentage and keep it in the
existing cell. I have a spreadsheet that has payment values in for customers.
I want to increase this amount by .08%. I have a mailmerge that creates
letters based on the amount in that cell that is why I need to keep it in the
same cell. thanks

In a blank cell enter 1.0008 (i.e. 0.08% increase) and click <copy>

Then select the cell you want to apply this to and Edit | Paste Special
| Values (check) and Multiply (check) and click OK followed by <esc> or
<enter>

In another cell input 1.0008.
Copy this cell and right click the cell you want to change.
Select Paste Special, and them select multiply.
Select Okay.
