I was wondering if there is a way to insert incremented conditions perpetually.

For example:

I'm trying to calculate how many hours it would take for a job.

For every 20 units, it takes me 30 minutes. My current formula reads:

=IF(AND(G17<=20),"0.5",IF(AND(G17>=21,G17<=40),"1",IF(AND(G17>=41,G17<=60),"1.5",IF(AND(G17>=61,G17<=80),"2",IF(AND(G17>=81,G17<=100),"2.5",IF(AND(G17>=101,G17<=120),"3",IF(AND(G17>=121,G17<=140),"3.5","5")))))))

I cannot go beyond this many nested formulas (excel warns and does not except the formula) but I have to be able to calculate working on much, much more than 140 units.

How can I increment with 30 minutes for every 20 units I work on in one formula?

Muza:

I suggest the following...

=(ROUNDDOWN((G17-1)/20,0)+1)*0.5

This is an algebraic solution instead of using a series of IF functions. This should work no matter what positive value you enter into G17.
