Default "IF" function: Can a calculation be an answer? help plz

Hi, Gord,
Almost there....but not quite. Checked out your answer. Used 2,500,000 in
A2, (assuming proposal was for $2.5M). I know this result would be $9000
premium due (2,500,000/1000)*.3.6.
Your equation gave me $8,000 (incorrect)

I went further and and used a hypothetical Proposal of $2,750,000.
The first 2,500,000 of this = $9000

the next 2,500,000 is rated at $3.20/1000. Which is would be calculated on
the difference between proposal amont of $2,750,000 - 2,500,000 =
250,000/1000 = 250 X 3.2 = $800

Total premium due = $9,800.00
Using your calculation, I get a result of $9,900.00

I've plugged in various other numbers in A2 and again,not getting correct
result. (BTW, in order to accurately calculate premium based on proposal
<$2,500,000, I have to delete the "0" in your formula, which does give me
correct premium, as it picks up the $3.60/$1000 premium rate.)

I'm working on it...see if we can both arrive at the correct formula using
lookup.

Thanks so much.
FMW


MANY THANKS!

Try this one to get premium due.

=LOOKUP($A$2,{0,250000.01,5000000.01,7500000.01},{ 3.6,3.2,2.8,2})*$A$2/1000

Hello, Biff,
Tried your formula:
=SUMPRODUCT(--(A2{0;25000;50000}),(A2-{0;25000;50000}),{0.05;-0.01;-0.01})
Did not work.

Perhaps I was not clear in what I was requesting:
In my job, we submit proposals for construction projects and if we are
awarded the job, we have to pay our insurance company a premium, based on our
proposal $:
So, say I submit a proposal for exactly $2,500,000, ez enough to figure out
(2,500,000/1000) = 2500 X $3.60 = a premium due to insurance company of:
$9,000.00

I have multiple propososals, ranging from $20,000 up to and over
$10,000,000. I am trying to figgure out a formula to use that will calculate
the premium based on the "sliding scale" rate the insurance company has us
pay:

Proposal Awarded for:
First 0$-$2,500,000 = $3.60 per $1,000
2nd 2,500,000 = $3.20 per $1,000
3rd 2,500,000 = $2.80 per $1,000
over 7,500,000 = $2.00 per $1,000


So, say for instance my proposal amount in A2 = $441,883.000.
Another proposal amount is $1,200,000.00 (I would insert this amount in A2).

Would you give it another try, while I also try to figure it out based on on
the formula you've provided.
(I'm pulling my hair out!!--It's probably so obvious and I am missing it!!!)

Again, MANY THANKS!

oops!

Typo:

=SUMPRODUCT(--(A2{0;25000;50000}),(A2-{0;25000;50000}),{0.05;-0.01;-0.05})

Should be:

=SUMPRODUCT(--(A2{0;25000;50000}),(A2-{0;25000;50000}),{0.05;-0.01;-0.01})

Try this:

Based on your table:

Example of commissions:
5% of first $25,000 premium
4% of next $50,000 premium
3% of remaining premium

A2 = premium

=SUMPRODUCT(--(A2{0;25000;50000}),(A2-{0;25000;50000}),{0.05;-0.01;-0.05})

BJ,
I've tried your equation...but I can't seem to get past the first part. I
have to calculate insurance premiums to pay, based on the $ amount of our
estimates to perform work. Insurance rate is based on a sliding scale:

First 2,500,000 = $3.60 per $1,000
2nd 2,500,000 = $3.20 per $1,000
3rd 2,500,000 = $2.80 per $1,000
over 7,500,000 = $2.00 per $1,000

I used your calculation below, and replaced the percentage points with
the
$/1000 above. But I am not getting the correct amount. I've also tried
the
MIN calculation. Both would be helpful.

MANY THANKS!

The format of your equation is wrong, try
=IF(A2<25000,A2*.05,IF(A2<75000,25000*.05+(A2-25000)*.04,25000*.05+50000*.04+(A2-75000)*.03))

or simpler
= A2*.03+Min(A2,75000)*.01+min(A2,25000)*.01

Using Excel XP. Trying to determine commissions that are on a sliding
scale.
Excel will not let me use a calculation as an answer in "value if
true" or
"value if false".
Example of commissions:
5% of first $25,000 premium
4% of next $50,000 premium
3% of remaining premium
Here is the IF formula I used:
=IF(A2<25000,"[+A2*.05]",IF(A2<75000,"[(25000*.05)+((A2-25000)*.04)]","[(25000*.05)+(50000*.04)+((A2-75000)*.03)]"))
The IF function itself seems to work, but instead of calculating using
the
value entered in cell A2, it just regurgitates the whole equation.
Sorry for such a technical question. Thanks for any help.
