Sorry-didn't explain properly. If I do a total of the data I've input
(I9-I11), the result is 855.29. The result of the calculation on that is
20.10, which is correct and what I need to see. If I don't do a total of the
input data, but do a sum of the calculated answers for each individual piece
it comes to 24.25. Why so much difference?

Are you saying that the total of:

-14.42 + -7.93 + -1.91

Should be -20.10

If so, you'll have to explain why you think that should be the result.

The formulas are returning the correct results. Maybe they're not doing what
you think they're doing.

I'm hoping someone somewhere can tell me what's happening and how to fix
it.
This is the formula I'm using:
=-MAX(0,MIN(I9,100)*0.05)+-MAX(0,(I9-100)*0.02) and copy down through I11

Starting in I9 I have the following amounts.
I Results i'm getting
570.75 (14.42)
246.36 (7.93)
38.18 (1.91)

If I do a Total cell and use the same calculation on it, the answer will
be
20.10, which is what I expect. The results of 9-11 are obviously going to
total to more than 20.10. Can someone explain what's happening and is
there
a way to fix it so that the results are reasonably in line. It seems to
me
to be too big a difference to be a rounding thing??

Thanks
