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

Do the cells N101 and N102 need to be equal % adjustment? or ?
Is the $12 always 12? Why $12? at least from the example?

N101 and N102 equal % adjustment is needed please.
No, $12 varies from one cost sheet to another.

Good now we're getting somewhere . . .
How will the $12 vary? % of margin? or something else?

I've asked the same question many different ways without any real answer other than 'just cuz I picked it' . . . lol I'm not a mind reader I don't know what you will pick next . . .

@CSmith as I mentioned earlier, $12 is not fixed. it could be $13 in the next sheet and $15 in the next sheet. This $12 price comes as word of mouth from bosses and we have to adjust that difference in the cost sheet.

The figure of 12 is not important and does not affect the method of calculation.

Actually it is it determines how much % I apply to each value to find some predetermined end result like ceiling of the next 4$ or something . . . Something or some reason for choosing the $12 as the appropriate value...

You don't have to do that.
All I can do is repeat (for about the fourth time) : format the cells as a number 0.00
Don't use TRUNC or ROUND in any of the formulas.

@footoo I already did that in P column so.... I am just keeping other two to see if there is any decimal difference among the three.

That is exactly the problem that is why the heading is "Calculating a Number from the very number it is based on" and i tried many way sometime ended up with errors and most of the times ended up with cross referencing..... This is the reason I came to experts!

just word of mouth, bosses gives the sheet and tell us make $12 for this one, make $13 for this one and so on....

Ok, so using what you just said you will have a number and then enter $12 into a desired value area and voila I can now give you $12 as a result from the above. . .
