I have a table with "ordered amount", "percentages", and "total sum". Note that "ordered amount" and "total sum" should be the same.
column F= sum of C:F
*rows 4,6,8,10 used =round()
As shown in the table(image), for some numbers, value in F is not the same as A when it should be. (e.g. A6(105) and F7(104), -1 after rounding).
Is there anyway to avoid this?
Thank you very much.
If the sum of the decimal points adds up to > 5, your final rounded number will round up. If they add up to < 5, the final number will round down.
Consider this example:
10.5 + 5 = 15.5, which rounds to 16.
However
10 + 5 = 15
This is what is happening in your table.
In order to get the sum of rounded numbers to add up to the same as the sum of the numbers, in your example, you will need to NOT round, but rather subtract, one of the values. I would suggest altering the largest value, as it would seem to have the least effect on the percentages, but that is a choice you can make.
To do that, with your data in row 8, for example you could do the following.
A9: =IF(B$8=MAX($B$8:$E$8),SUM($B$8:$E$8)-SUM(ROUND($B$8:$E$8,0))+ROUND(B$8,0),ROUND(B$8,0))
entered as an array formula with ctrl+shift+enter and fill right to E9.
This would give a sum of 344 which is the same as F8

I'm trying to write a code in Excel that basically counts multiplies valueA by 5 when ValueA<=15. Once valueA surpasses 15 (therefore ValueA>15), it will the multiply ValueA by 9 for the remaining amount value. For example, if ValueA=20, 1-15 will be multiplied by 5, and the 16-20 will be multiplied by 9, to give the total amount.
Can anybody else out with this?
So far, I have:
=IF(AND(A2="LR",B2<=15),B2*5, IF(AND(A2="LR",B2>16....
not sure how to finish off!
=IF(AND(A2="LR",B2<=15),B2*5, IF(AND(A2="LR",B2>15),B2*9-75, ... Whatever value you want if A2 doesn't equal LR))
Consider the following sheet/table:
A B
1 90 71
2 40 25
3 60 16
4 110 13
5 87 82
I want to have a general formula in cell C1 that sums the greatest value in column A (which is 110), plus the sum of the other values in column B (which are 71, 25, 16 and 82). I would appreciate if the formula wasn't an array formula (as in requiring Ctrl + Shift + Enter). I don’t have Office 365, I have Excel 2019.
My attempt
Getting the greatest value in column A is easy, we use MAX(A1:A5).
So the formula I want in cell C1 should be something like:
=MAX(A1:A5) + SUM(array_of_values_to_be_summed)
Obtaining the values of the other rows in column B (what I called array_of_values_to_be_summed in the previous formula) is the hard part. I've read about using INDEX, MATCH, their combination, and obtaining arrays by using parenthesis and equal signs, and I've tried that, without success so far.
For example, I noticed that NOT((A1:A5 = MAX(A1:A5))) yields an array/list containing ones (or TRUEs) for the relative position of the rows to be summed, and containing a zero (or FALSE) for the relative position of the row to be omitted. Maybe this is useful, I couldn't find how.
Any ideas? Thanks.
Edit 1 (solution)
I managed to obtain what I wanted. I simply multiplied the array obtained with the NOT formula, by the range B1:B5. The final formula is:
=MAX(A1:A5) + SUM(NOT((A1:A5 = MAX(A1:A5))) * B1:B5)
Edit 2 (duplicate values)
I forgot to explain what the formula should do if there are duplicates in column A. In that case, the first term of my final formula (the term that has the MAX function) would be the one whose corresponding value in column B is smallest, and the value in column B of the other duplicates would be used in the second term (the one containing the SUM function).
For example, consider the following sheet/table:
A B
1 90 71
2 110 25
3 60 16
4 110 13
5 110 82
Based on the above table, the formula should yield 110 + (71 + 25 + 16 + 82) = 304.
Just to give context, the reason I want such a formula is because I’m writing a spreadsheet that automatically calculates the electric current rating of the short-circuit protective device of the feeder of a group of electric motors in a house or building or mall, as required by the article 430.62(A) of the US National Electrical Code. Column A is the current rating of the short-circuit protective device of the branch-circuit of each motors, and column B is the full-load current of each motor.
You can use this formula
=MAX(A1:A5)
+SUM(B1:B5)
-AGGREGATE(15,6,(B1:B5)/(A1:A5=MAX(A1:A5)),1)
Based on #Anupam Chand's hint for max-value-duplicates there could also be min-value-duplicates in column B for corresponding max-value-duplicates in column A. :) This formula would account for that
=SUM(B1:B5)
+(MAX(A1:A5)-AGGREGATE(15,6,(B1:B5)/(A1:A5=MAX(A1:A5)),1))
*SUMPRODUCT((A1:A5=MAX(A1:A5))*(B1:B5=AGGREGATE(15,6,(B1:B5)/(A1:A5=MAX(A1:A5)),1)))
Or with #Anupam Chand's shorter and better readable and overall better style :)
=SUM(B1:B5)
+(MAX(A1:A5)-MINIFS(B1:B5,A1:A5,MAX(A1:A5)))
*COUNTIFS(A1:A5,MAX(A1:A5),B1:B5,MINIFS(B1:B5,A1:A5,MAX(A1:A5)))
The explanation works for bot solutions:
The SUM-part just sums the whole list.
The second line gets the max-value for column A and the corresponding min-value of column B for the max-values in column A and adds or subtracts it respectively.
The third line counts, how many times the corresponding min-value for the max-value occurs and multiplies it with the second line.
Can you try this ?
=MAX(A1:A5)+SUM(B1:B5)-MINIFS(B1:B5,A1:A5,MAX(A1:A5))
What we're doing is adding the max of A to all rows of B and then subtracting the min value of B where A is the max.
If you have Excel 365 you can use the following LET-Formula
=LET(A,A1:A5,
B,B1:B5,
MaxA,MAX(A),
MinBExclude, MINIFS(B,A,MaxA),
sumB1,SUMPRODUCT(B*(A=MaxA)*(B<>MinBExclude)),
sumB2,SUMPRODUCT(B*(A<>MaxA)),
MaxA +sumB1+sumB2
A and B are shortcuts for the two ranges
MaxA returns the max value for A (110)
MinBExclude filters the values of column B by the MaxA-value (25, 13, 82) and returns the min-value of the filtered result (13)
sumB1 returns the sum of the other MaxA values from column B (26 + 82)
sumB2 returns the sum of the values from B where value in A <> MaxA (71 + 60)
and finally the result is returned
If you don't have Excel 365 you can add helper columns for MaxA, MinBExclude, sumB1 and sumB2 and the final result
I have a list of product price that i need to markup.
I've tried using with Regular Formula
=A1*10%+A1+5,000 = 36,130 (A1 = 28,300)
Is there any way to remove the last 2 Digit and adjust the price if the price result is 36,130 it will remove the 30 (36,100) but if the price 36,160 it will adjust to 36,200 ?
Use:
=MROUND(<YourExpression>,100)
In order to round up to a certain number of digits, this is what I usually do (example of 2 digits):
multiply by 100
round to the nearest integer
divide by 100 again
(use 1000 for 3 digits, ...)
For rounding, you might use the ROUND() worksheet function.
I have a formula which gives me different dates depending on the multiplier. I am not sure how it works though, except that it rounds a date. The formula is the following:
=DATE(YEAR($L$4),CEILING(MONTH($L$4),2),0)
So imagine today´s date is 18/08/2015 in cell L4. If i change the multiplier i get the following results:
=DATE(YEAR($L$4),CEILING(MONTH($L$4),2),0) = 31/07/2015
=DATE(YEAR($L$4),CEILING(MONTH($L$4),3),0) = 31/08/2015
=DATE(YEAR($L$4),CEILING(MONTH($L$4),4),0) = back again to 31/07/2015.
Why does this happen? Why does it go back to 31/07/2015 if the multiplier increases to 4?
=CEILING('number', 'multiple') returns a multiple of the 'multiple' that is nearest to the 'number'.
Since MONTH evaluates to 8 or August, you would have =CEILING(8, 3), which evaluates to 9, because 9 is the multiple of 3 closest to 8. 2 and 4 as multiples will both return 8.
=DATE(2015, 9, 0) will return the last date of the previous month, because the day is 0.
If you tried your formula with CEILING(MONTH($L$4), 10), you would get 31/9/2015, because the multiple of 10 nearest to 8 is 10, and the DATE formula will end up looking like =DATE(2015, 10, 0) which evaluates to 31/9/2015.

I have a table which describes "Products Per User" distribution.
It has 2 columns nProducts and nUsers:
First row has values nProducts = 1, nUsers = 60000, meaning 60000 users bought 1 product.
Second row has values nProducts = 2, nUsers = 20000, meaning 20000 users bought 2 products, and so on...
I want to calculate its STDEV. How do I do it in excel?
In addition, could you tell me how to calculate in excel how many users bought:
nProducts > thresh?
Thanks
Li
Do you mean you want to calculate the standard deviation of the number of products bought? Try this "array formula"
=STDEV(IF(B2:B10>=TRANSPOSE(ROW(INDIRECT("1:"&MAX(B2:B10)))),A2:A10))
confirmed with CTRL+SHIFT+ENTER
So in a small example if you have 1 product bought by 4 people and 2 products bought by 3 people that will give you the standard deviation of the following values
1,1,1,1,2,2,2
Is that what you need?
Note that you can also use this "non array" version
=(SUMPRODUCT((A2:A10-SUMPRODUCT(A2:A10,B2:B10)/SUM(B2:B10))^2,B2:B10)/(SUM(B2:B10)-1))^(1/2)
which calculates standard deviation by calculating the square root of the average of the squared differences of the values from their average value
Just select all the second column values.
Then on the Ribbon bar:
go to Forumulas
click More Functions
select Statistical
click on STDEV.P
At this point as parameters you should have your second column already selected, just clik OK and you will have your Standard Deviation calculated.
In case you can write it manually the formula is =STDEV.P(B2:B10)
I supposed you have values from the 2nd to the 10th row in column B.
