J,

Looks to me like you're performing the calculation twice:

=20%*(F4-D4*38.46) gives you 303.76
and
+IF(F4-D4*38.46)0,(F4-D4*38.46)*.2,0)

resolves to give you the same amount again, the two of which are then added
together.

Good luck,
Tom Hayakawa

Hello all,
I have an IF function to calculate Federal Tax. In the Function Arguments
Dialog Box the logical test = True, and the Value_if_true = 303.7605, which is
what I want. The Value_if_false = 0, which is also what I want. The formula
result in the bottom left of the dialog box however = 607.52. Double what it
should be. I have uploaded a screenshot here http://home.earthlink.net/~janderson3/
Any suggestions as to what I'm doing wrong would be appreciated.
Thanks in advance.
