Will I speed up calculation if I add an IF before a huge formula?

[whatever61]

When I have a very heavy formula and before the whole formula I am adding an IF formula and if it's true and it will get the result.
Will it make my formula less heavy? I mean will it not conitnue calculating the other conditions then?

Example:

The current formula:

=IF(something very complicated, bla bla, if(complicated.... and etc.)

The optimized formula:

=IF(B2="","V",the current formula)

When the first condition is true (B2=""), will it not continue the calculation and thus the formula will be calculated quicker?

I hope it is clear what I wanted to say

Thanks

I would expect so as excel is only doing the big calculation when needed. best way to see how much effect you get is to try it. Small file won't make an appreciable difference. large one might. It will all depend on how much work is involved with your big complicated blah blah.....
