If I'm referring to a cell many times in a workbook, is there any difference
between linking to the cell reference (ie $A$3) or naming the cell and
linking to the name? Would it speed up calculations to link to a name?

Thanks

Adam Bush

Just my guess...

I'd bet any difference in calculation would close to unnoticeable by the human
eye. I think the better reason for doing it is to make updates easier. And
using a nice name can make the formula much more self-documenting, too.

Dave,

How about if I have a very long formula with if statements. Would it speed
up calculations to create a function in VBA rather than putting this long
formula in every cell?

Thanks

My bet is no.

For the most part, UDFs are much slower than using the functions built into
excel.

Dave,

But I'm not using a function built into excel, I'm using a formula with six
if statements and several polynomials. Would the UDF improve this?

Thanks

Almost certainly not. It is very hard to get even near the speed of Excels intrinsic calculations, both formulas and functions.

Niek,

The reason I'm asking this is I have an entire worksheet that does
calculations for a formula that can all be condensed in VBA. This would save
me a pretty large worksheet worth of calculations. Do you think this would
speed up my workbook at all if I got rid of this extra worksheet?

Thanks

Hi Adam,

Most tests show that the number of formulas to be evaluated is more important for performance than the complexity of the formulas
itself. So that makes you think that missing an entire sheets should help.
But then again, UDFs are mostly much slower than comparable formulas.

Why not try? Do let us know your findings!

BTW, if performance is a problem, visit Charles Williams' site for lots of tips and information:
