    Reduce cells by fixed amount

    Hi, fairly new to Excel and need assistance.
    I have several ranges of cells i.e. A1 to T1 etc that contain varying figures I want to
    create a formula that will reduce each cell by a fixed amount i.e. $800.00. Can someone assist? Also a formula to increase or decrease cell amount by a percentage.

    Many thanks
    Richard

    Re: Reduce cells by fixed amount

    If the fixed amount were in Z1, then the A1 formula would be:

    =500 + $Z$1

    Obviously, the "500" can be replaced by the existing formulas that "add up" to 500, whatever is currently in the cell (formula, that is). Then copy A1 across to T1.

    If A1:T1 do not have formulas in them, rather have constants typed in, then no "formula" will do what you want IN the original cells. you could put a formula in the row below... in A2:

    =A1+$Z$1

    ...and copy across row 2.


    Percentage changes are similar:

    =A1 * (1-$Z$1)
