# Weighted SUM By Criteria

Jan 22, 2008
I am trying to find a formula that will calculate a running total of employee time off. Time off is recorded in Excel spreadsheets that I created. V = vacation, S = sick, PD = personal day, and so on.

For example: If a V is entered in any cell in their attendance worksheet, I would like for a 1 to display under the vacation total column. The next time a V is entered in, I would like it to update the cell containing the vacation days used for the year to 2. If a 1/2 V is entered, a .5 would be added to the total used.

I have trouble finding the right formula for a weighted average price. The formula which i used in cell B2 of the attached file doesn't exclude irrelevant numbers. In the formula "= sumproduct(a5:a21;b5:b21)/sum(b5:b21)", i like to exclude cells B8, B9, B15, B19, B20 because the list prices are missing. How can i exclude these irrelevancies in the formula above?

I have a data set that looks something like the following:

TypeAmountCost

A100$50

A200$40

A300$35

B250$40

B275$55

B500$60

A700$20

B350$25

B450$35

C400$80

C400$60

I am having trouble creating a formula that would calculate the weighted average cost depending on the type (i.e. weighted average cost of $28.84 for A, weighted avg cost of $70 for C).

It is a database in which each row represents a unique individual.

Columns A - G contains information which is irrelevant for this question

Columns H - CQ contains answers to the individual's questions (Yes/No or "-" for N/A)

Column CS contains a array formula which determines the % of "Yes" answered only in Question 1 (Columns H to X).

The formula finds all "S1*" (within H1 to CQ1) and if the corresponding "S1" has a "Yes" (within eg. row 2 - H to X) it adds it and divides by the total number of "S1" (17 in this example excluding the "-")

Eg:

In Row 2: S1 = 17, Yes = 7, "-" = 0, % = 7/17 =35.29%

In Row 3: S1 = 17, Yes = 8, "-" = 1, % = 8/16 = 50%

So I have the array formula in column "CS" which does the above.

What I want to achieve:

I want to get the average of all the individual rows in column "CS". This is shown in "CS1 (48.32%". I am looking for a way I can achieve this with just one formula - A formula which first calculates the individual %s and averages the %s within the same formula.

I have a large dataset that includes information on the investment payout ratios of US companies over the period 2004-2006. I need to calculate the weighted average investment ratio for each company---see sample below

Microsoft Excel - example.xls ....

[HtmlMaker 2.42] To see the formula in the cells just click on the cells hyperlink or click the Name box

PLEASE DO NOT QUOTE THIS TABLE IMAGE ON SAME PAGE! OTHEWISE, ERROR OF JavaScript OCCUR.

The corresponding weight for each year must be as follows: 0.5 for 2006, 0.3 for 2005 and 0.2 for 2004. Then, for company A, the weighted average will be: (0.5*B2)+(0.3*C2)+(0.1*D2) = 7.8 (see cell E2)

The problem is that for some companies there are missing data for some years. For example, for company B, there are no data available for year 2004. In this case , the weights have to change to 0.6 for 2006 and 0.4 for 2005. Then, the weighted average investment for company B will be (0.6*B3)+(0.4*C3) = 16 (see cell E3). Similarly, in cases when there are data for only 1 year , the weight has to change to 1. Then, for company C the weighted average is 35 (see cell E4)

Is there any formula to give me the weighted average as it appears in column E without having to adjust it for each single case?

I'm doing a GCSE project for which I need a little help with Excel.

I have a set of data about a persons monthly spending habits on

Food 300

Entertainment 200

Clothing 100

Transport 260

The pre calculated budget allowance for the month was 500

I would like to write a formula that would do the following; give the person an score out of 1.1-10 based on how well he spent on the above items which are in order of priority (i.e. it is better to spend more on food than on entertainment etc) And then an over all score (1.1-10) that will reflect how well they spent.

In Col DL are digits ranging from 1-36, in Col Dm are the number of times they were drawn in 36 draws. I have a weighted avg formula in Col DN, that I found thru search, but it doesn't appear to be working right or maybe I don't understand the formula. I have no idea if this can be done.

I have a spreadsheet which basically looks like this

2, 5, 15, 20

2, 8, 12, 13

2, 7, 19, 46

F, 1, 10, 26

P, 1, 10, 39

P, 6, 22, 89

P, 7, 14, 46

P, 2, 11, 14

...

Column A is the key. If multiple rows have the same key, they're related.

The last column (DX on my spreadsheet) represents minutes participated, and is the weight variable. The middle columns are data that I'd like a weighted average for.

Here is the output I'm looking for given the above example:

2, 6.66, 16.83, 79

F, 1, 10, 26

P, 4.91, 16.73, 188

Column A remains the same, with one row for each key. The middle columns have their weighted average (where 6.66 = (5*20+8*13+7*46)/(20+13+46)), and the final column (DX) is the sum of minutes for all like keys.

I have long lists of data which has name of manufacturer, number of items and fault rates of items.

E.G

Manufacturer.......Number of Items......Fault Rate

Dell....................40000....................0.2%

Dell....................42200....................0.4%

Sharp.................303003..................0.1%

Microsoft.............312340..................0.04%

Dell....................3249321..................1%

Panasonic............300020...................2%

I need to find the weighted average of each manufacturers fault rate for just themselves, and also how the average of all the manufactueres would be if they weren't in it.

So for example for Dell I would need their weighted average of their three data entries and also then the weighted average of Sharp, Microsoft, Panasonic together.

I have been doing this by splitting the data into sections so for the example above I would do:

Manufacturer.......Number of Items......Fault Rate

Dell....................40000....................0.2%

Dell....................42200....................0.4%

Dell....................3249321..................1%

Panasonic............300020...................2%

Sharp.................303003..................0.1%

Microsoft.............312340..................0.04%

I would sum the Dell items, then sum the number of items excluding Dell then do two weighted average calculations giving me the ones that include then the ones that exclude Dell.

Then I would do...

Manufacturer.......Number of Items......Fault Rate

Sharp.................303003..................0.1%

Microsoft.............312340..................0.04%

Dell....................3249321..................1%

Dell....................40000....................0.2%

Dell....................42200....................0.4%

Panasonic............300020...................2%

And do the same process but with Sharp totals etc then move onto the next one.....

This example is with a very small data set so I'm sure you can see that this process is very time consuming, but I don't know any other way of doing it without splitting out the data first.

I have a set number that I need to allocate over a flexible period of say 5 -11 days.

I have applied the traditional split per day to each number i.e. a monday normally results in 20% of transactions, Tuesday 25% etc.

The issue comes in when I try to allocate the budget over a period longer or shorter than a week.

Therefore the budget for the 9 days is being allocated over the period of 9 days which results in a overall allocation of 150%. (duplicate mondays etc).

Is there a way to limit the entire period to a set number and have the numbers adjust themselves accordingly up or down to match it other than multiplying it by a factor?

Example attached: Excel Problem.xlsx

I have two columns. One has cost (column A) and the other has profit (column B). I'd like to calculate the percentage profit as a function of how much something cost. So, if it cost $100 and the profit was $20 I would like to calculate 20%. For all percentages, I'd like to average them. I understand this is a "weighted average" and was able to get this working with this formula:

I'm trying to use the 2007 histogram tool (or frequency) to show me the frequency of data, but my data is in a different form than required for either of these tools. Let me use the following simple case -- to show the frequency of student grades both tools assume I have a list of student's test grades. What if I instead have more than one column, e.g., "grade" and "number students with that grade"??

My application is actually different, but it's still 2 columns, a numeric property and a weighting factor (e.g., fraction of the total).

I created an Excel tool into which really thousands of records are based on weighted averages calculations. And discovered Excel struggling in term of permormance.

The issue is: the user needs to uploads a couple of times in a day new data for further analysis, and the only way to make the Excel spreadsheat humanely usable (performance) was to calculate everything upfront.

To optimize the tool performance, I had to:

- First I made all weighted average calculations upfront when data is uploaded the first time. Leaving formulas in the tool was not viable, since this tool run live analysis, every click would have been a pain of 30 sec at best to re-calculate new conditions,

- Second optimization was to not leave formulas into columns > as soon as a calculation is done, the macro copy/paste values

The formula I chose is sumproduct based weighted averages..

Here is my question:

1. Does it exits specific formulas in Excel to handle nicely large amount of weighted averages to calculate ?

2. Should I consider to use an external application (an Access table, SQL or whatever) to perform those weighted average calculations quickly/quicker.

Each individual enters 6 different qualifying numbers (columns) resulting in a "place" in each column. Placement in each of those columns is equal to the other columns or as important as the other. Is there a way to set up a formula to reflect each individuals "place" in each column and then have those columns weighted equally and averaged to determine the Winner?

In my spreadsheet (testing.xls) I have a chart to mark the quality of a phone call based on a list of 8elements being judged. I have a likert scale for the quality result for each element, say for example 5 for highest, 3 for average, 1 for the poor, 0 for very poor and NA for an element which is not counted.

At the bottom of my table I have a cell where it would work out the % based on the outcome of the result from the different cells being ticked, what would i need to do to have excel work this out for me? Please bare in mind that if there is for example 1 element out of the 8 elements marked as NA the result would be divided 7 instead of 8.

What I am trying to do is rank my employees based on certain metrics. They are weighted in three different catagories. Talk time is 40%, Quality 50%, Attendance is 10%. I can weight the Talk Time and Quality, as those are basically the higher the score the better the weight. Attendance is the opposite, the lower the number, the higher the weight. Meaning, if employee has 1 absence that would better than someone who is at 4 absences. Is there a way to do this. I am somewhat educated on VBA, I understand if,then,else statements and/or Select/Case statements, so if I needed to do it in VBA I can. I just need direction to get it going.

DATA: D1:D11 contains either blank cells or a dollar figure from a payroll check.

E1:E11 contains either blank cells or the date of the check.

Current Situation: Using the following formula I obtain a weighted average of the pay checks, not including the largest. =(SUM(D1:D11)-MAX(D1:D11))/(COUNT(D1:D11)-1)

Problem:

I desire to calculate the weighted average based on the checks issued only prior to a certain date. I have used SUMIF() in other parts of the workbook successfully but needing to withold the largest value has presented me with a problem I can not find a solution to. =SUMIF((E1:E11,">="&TargetDate,D1:D11)-MAXIF(E1:E11,">="&TargetDate,D1:D11))/COUNTIF(E1:E11,">="&TargetDate,D1:D11)

See attached picture. This shows Profit and Growth for the stores in each region.

The percentage total is weighted based on the profit of each store in the region.

What I have is an excel sheet with hundreds of regions (going down), all with a different amount of stores. I need a way to populate each of its Region % Total with the weighted average formula (in my example, cells C8, C12, and C20) while also varying the formula to include only the stores in the region.

For example, C8 calculates the weighted average for %s in rows 2 through 7 (6 stores), but C12 calculates it for rows 9 through 11 (3 stores). I need the formula to vary based on the number of stores.

I am making a spreadsheet that requires multiple dates and percentages. Is there any way that I can make the percentage that is related to the most recent date weighted more than a percentage with a date from a month or two ago?

For example:

X//Y//DATE

90%//85%//3-March

85%//70%//21-May

87%//90%//6-June

Is there formula so that I can have the 90% and the 87% be the most important (or weighted), the 70% and the 85% be the second most important, and the 85% and the 90% be the least important when I average them out?
