LOOKIN FOR FORMULAS,

Please read the other responses to your post. Those will do what you asked.

James answer will kinda do what you ask, but instead of replacing the value
in the cell, it will keep the original value and display your desired result
in a different cell.

What you are asking can not be done with a formula. You need to change the
value of the cell. The other 2 responses will change the value of the cell
(Paste SpecialMultiply).

HTH,

Conan

Thank you for your reply.
But excel doesn't let me put that in. If I use the same cell number,
excel
doesn't use the value, it emptys it.
Help Thanks

I need to add 10% to a value that already exist in the cell
Example. Cell C4 contains the value $1.00
I want to add 10% to $1.00 and replace the $1.00 with the answer $1.10
HELP.

=(C4*.10)+(C4)

This should do it. (1.00 * .10) + (1.00) = 1.10
