Hello Experts,

I have a problem and need your help please. I need to bring total price of 8.91 to 12.00 but the problem is with 3% commercial cost and commission because it is calculated on the very same value which needs to be adjusted.

Is there any formula or similar to get around this please?

Below is just a summary for ease of understand. Actually ton of background calculations are involved in multiple sheets.

Thanks in Advance.

BELOW IS FIXEDTWO ITEMS CAN CHANGE
Trim Cost (A)$1.60$1.60CAN NOT CHANGE
Fabric Cost$2.99$5.16CAN ADJUST
Accessories Cost (B)$1.28$2.21CAN ADJUST
CM COST$2.96$2.99CAN NOT CHANGE
Commercial %3% OF A+B$0.08$0.08CAN NOT CHANGE
Total$8.91$12.04CAN NOT CHANGE
Commission %0$0.00$0.00CAN NOT CHANGE
TOTAL PRICE$8.91$12.00THIS IS TOTAL

"Don't use TRUNC. It will make the differences worse. Format the cells to 2 decimals. (noted, will try it three ways in format to 2 decimals, round to 2 decimals and trunc to 2 decmials in three columns side by side to see what effect each brings )"
No. Just format the cells as number with 2 decimal places 0.00
(Right click>Format Cells>Number tab>Number>Decimal places: 2>OK

I couldn't work out formulas that avoid circular references (maybe someone else can), so below is a macro.
Before running the macro, do the following :
• Put 2.99 in N101 (no formula, but must not be blank)
• Put 1.28 in N102 (no formula, but must not be blank)
• In N105 put this formula : =SUM(N100:N104)*M105
• In N106 put this formula : =(SUM(N100:N105)+(SUM(N100:N105)*M106))*M106
• In N107 put this formula : =SUM(N100:N106)
• Put 12 in N108 (no formula) - you can put any total you want

After that, run the macro :
VBA Code: 
Sub Calculate_N101_N102()
Dim totalCost!: totalCost = [N108]
Dim x!, y!
[N107].GoalSeek Goal:=totalCost, ChangingCell:=[N101]
x = [N101]
y = [N102]
[N101] = (x + y) / ([J101] + [J102]) * [J101]
[N102] = (x + y) / ([J101] + [J102]) * [J102]
End Sub

thanks @footoo

noted, will format it to two decimal places.

VBA scripts and Macros are not an option. But thanks anyway.

There is one aggregate function could that help in anyway? or any other way around it?

@kvsrinivasamurthy @CSmith Would you be kind enough to look into the problem and help to solve please?

Thanks.

Excel Facts

Select all contiguous cells
Pressing Ctrl+* (asterisk) will select the "current region" - all contiguous cells in all directions.
Other than a formula, could do with Goal Seek, but presumably you do not want to do manually.

Using Goal Seek will be quite messy in that a helper column will be required and if you want to remove it later, the formulas in N101 & N102 would first have to be converted to values only.

If we need to convert the formulas to values then the whole purpose of automating the process will die :(

First let's start with how do you know it needs to be $12?
Something is missing from the details, but are you looking to generate the $12 or the numbers $5.16 and $2.21?
It looks like based on the sample data you provided the COMMISSION is 0%? But in other text you as for COMMISSION AND COMMERCIAL % to both be 3%?

Without better idea of what direction you are "needing" to go I cannot provide a solution that fits your "needs". All I can do is throw out suggestions.

Perhaps you might:
  • Stated your business case at the top and how you might adjust the values? Should they be linked adjustments within a given % of deviation?
  • Stated what you’ve tried . . . There is a disconnect of your data from your description and it is difficult to get a clear picture of an answer without concise delimiters of how things are/can be adjusted.
  • Explained what should have happened and why it should be that way . . . Your data shows you trying to get to $12 but why/how did you get that number?
  • A xl2BB would have made this the perfect post!

Thanks @CSmith

I'll try to explain as much as possible in red.

First let's start with how do you know it needs to be $12? ....We get this number by word of mouth that we need to bring that calculation to this number, no logic, no reference to the is number and it varies from one cost sheet to another......
Something is missing from the details, but are you looking to generate the $12 or the numbers $5.16 and $2.21? ....$12 is fixed not generated, we need to adjust above prices to bring that number from original to new price......
It looks like based on the sample data you provided the COMMISSION is 0%? But in other text you as for COMMISSION AND COMMERCIAL % to both be 3%? ....yes, initially I tried with commercial only (which is calculted on sum of three cells j100+j101+j102) and its not 3% fixed, % varies from one sheet to another. For commission, it should be calculated on $12 which will then go into $12 itself with other numbers. commission is also not fixed, it also varies from one sheet to another.

....I am all here and I can explain everything again if have any questions... basic idea is to get $9.14 to $12.00 in with making adjustment in: (1) total of part "A", j101 (2) total part "B" j102, (3) j105 (4) j106
Perhaps you might:
  • Stated your business case at the top and how you might adjust the values? Should they be linked adjustments within a given % of deviation? .....yes should change with % deviation....
  • Stated what you’ve tried . . . There is a disconnect of your data from your description and it is difficult to get a clear picture of an answer without concise delimiters of how things are/can be adjusted. ....tried again above in red......
  • Explained what should have happened and why it should be that way . . . Your data shows you trying to get to $12 but why/how did you get that number? .....explained as above.....
  • A xl2BB would have made this the perfect post! .....sure, attaching the same again.....

This might help :

shah101 has sent xl2BB’s with his posts.
What he wants in N101:N108 is as follows :

N100 1.60 (fixed)
N101 Change the 2.99 in J101 to make the Total 12.00
N102 Change the 1.28 in J102 to make the Total 12.00
N103 2.96 (fixed)
N104 0.00 (fixed)
N105 Formula to calculate 3% of N100:N102 (fixed formula)
N106 Formula to calculate 1.5% of the Total, net of this amount (fixed formula)
N107 Total of N100:N106
N108 12 (the required Total)

Basically, he just needs to calculate the amounts for N101 and N102.

I’ve provided a macro that does what he wants, but he can’t use a macro.

thanks for explianing @footoo

only thing is the 3% and 1.5% varies from one sheet to another so there is a cell where one can put in the %.

I thought you were removing TRUNC from your formulas - it doesn't do what you need.
