Complex IF formula

[elanum]

Going to try to give some background on the data of this needed formula so that hopefully its clear (as mud?) for whoever is so gracious to help me.

Nomination = Estimated Gas flow
Burn = Actual gas flowed
Imbalance = Nomination minus Burn
Tolerance = Amount of Imbalance allowed before the shipper has to park/loan the gas

The formula that I want to create is going to look for the gas outside of the tolerance.

Here is the tolerance per the contract:
nomination </= 50,000 = +/- 5,000 tolerance
nomination > 50,000 = 10% tolerance

Ex. 1
Nom = 10,000
Burn = 6,000
Imb = 4,000
Tolerance = +/- 5,000 (because the nomination is less than 50,000)
Gas outside of tolerance = 0 (Imb < 5000)

Ex. 2
Nom = 25,000
Burn =34,000
Imb = 9,000
Tolerance = +/- 5,000 (because the nomination is less than 50,000)
Gas outside of tolerance = 4,000 (Imb > 5,000, therefore 9,000 minus 5,000)

Ex. 3
Nom = 56,000
Burn = 70,000
Imb = -14,000
Tolerance = 10% = 5600 (56,000 * 10%)
Gas outside of tolerance = -8400 (5600 - 14000)

Ex. 3
Nom = 56,000
Burn = 46000
Imb = 10,000
Tolerance = 10% = +/- 5600 (56,000 * 10%)
Gas outside of tolerance = 4400 (10000 - 5600)

One issue I see with creating a formula is with the 10% tolerance, because it can be plus or minus the nomination. See the green highlights above.


Here is a walkthrough of how I envision the formula…
Nom = Cell Q4
Burn = Cell R4
Imb = Cell T4

IF Q4 <= 50000, then if T4>5000 or T4<-5000, then T26-5000, otherwise 0.
If Q4 > 50000, then if (0.1*Q4) > T4 or –(0.1*Q4) < T4, then T4 – (0.1*Q4) or (0.1 * Q4) – T4, otherwise 0.

I’d like this to be just one formula, but if that isn’t at all possible, I can have 2 different formulas.

i would suggest you upload a sample work book, (all sensitive data removed), showing what data you are working with, a few examples of what your expected outcome is, and how you arrived at that
To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.

Here you go, just need to use the ABS() function to get absolute value.

Or using only one formula from the two input columns.
