Instead of using I4 in your formula, write it as $I$4 - this is using
absolute references and will not change when you copy the formula
across or down.

Hope this helps.

Hi,

I'm trying to create a worksheet that calculates the compounding
effect of a specified percentage increase on a given starting figure
i.e. starting with 100 and increasing it in steps by 10% each time.

How do I copy the formula I've created whilst stopping Excel from
automatically changing the reference of the cell containing the
percentage I want to use? I want every formula to refer to cell I4
which contains the percentage I'm using instead of changing it to I5,
I6, I7 etc

To put it another way, how do I tell Excel that one cell referenced in
the formula is not to change whilst the others are?

I hope that makes sense....it's a simple problem but a difficult one
to put into words.

Many thanks

Paul

Brilliant, thanks very much.....I knew it would be something simple.
