IF Then - Using 12 Months - Ongoing Average
Mar 7, 2009
The formula works but under very strict conditions. The spreadsheet has columns for all 12 months, a yearly total and an average column. The “If – Then” is for the average column for entire year. No matter what the month it will calculate the average using the appropriate number of months to divide by, now here’s the catch; each previous month has to have a number greater than “0” and luckily I have but if a previous month has a "0" it blows the formula out of the water. I had to split the into IF-Then into two sections because of the embedding limitations so when I have a lot of items that I need to do this for you can see I am having to reproduce this formula multiple times and tracking gets a little confusing. Example......

I'm trying to make a formula that will calculate the average of the previous 12months. The goal is to tie the formula to a reference cell that contains a date. Each time the date is changed by a user the calculation will be updated accordingly. Here is the CSE formula that I thought would work:
{=AVERAGE(IF($B$5:$B$53=B$2,OFFSET($C$5,(COUNT(C5:$C$53)-1),0,12,1)))}
I've also attached a sample file to illustrate the problem. The 'range' portion ($C$5,(COUNT(C5:$C$53)-1)[/b]of the Offset function was setup simply to get the 12 months which preceeded the reference date.

I wrote code that works just fine, however, I realized there were parts of the data I was using that had 0's in it for holiday.
Bottom line, this is code that calculated the weighted average of prices for 12 months (12 rows across) and Drows across. I'm trying to use the "do while is empty" approach but can't get the syntax to work. Here's the code
Code:
For r = 1 To drows
Totwavg = 0
Tothours = 0
priceavg = 0
For n = 1 To ncontracts

I am trying to calculate the average headcount for different categories (over a certain period of time, by product, by job type etc) and I want to do it using a formula instead of a pivot table.
I have this set of data with a detailed headcount for every month. And I can find out the total HC for different categories using sumif/sumifs but if want to find out the average for a certain period, I need to split that total to the number of months where I have a HC.
For example, if the HC per month would be:
May 2013 - 12
June 2013 - 10
July 2013 - none
August - 5
in a 4 months period I would have a total HC of 27 and the average would be 9 (27/3 - July shouldn't be counted). How can I get the average in a single formula?
Month
Type
L/H
Prod type
HC
[Code].....

I basically need to add the ongoing totals for each house team-so when scores are inputted, the house teams score is automatically being added up.....I think I would need to mail someone the sheet to show how far I have got as I dont think it is a simple count formula.

In the file attached there is only the data to look at, though file is little bit lager.
Now in cell G10 I've got the stock forecast in 3 months time, this stock forecast is calculated from a date rounded to the closest month (according to my criteria), then the formula looks at the reference number cell D1 to work out the formula. All the steps are in the file.
In order to be more accurate my boss and I want to use the exact date, so that delete all the round month process. My intention is to use the day of the date and then make a fraction of the months to calculate the average. Taking into account that a month have as an average of 30.4166 days.
In the file I did an example, to clarify my messy explanation.
Cells B2, C2, D2 won't be needed in order to do so.
Please have a look at the file. At the end my intention is to to such a formula or a similar one. The formula should be an automatic one when typing dates in cell A10
The result of it is in row 31 and 32.

I'm using Excel 2010
I'm working on a workbook for tracking debt. It has 15 sheets. Instructions, Charts (for showing debt change over time), "Invisible" (this is where my chart data is, I plan to hide it), and 12 month sheets. On the Invisible sheet, for example, I have my data set up. I'm pulling the data from other sheets. In the screenshot, I'm using =Month12!P48 as the formula to pull my data from the other sheets. But, the user hasn't entered data yet for month 12, so the line chart drops to zero there. I want it to just stop and do nothing, until there is data in that cell. (I would prefer to use a line chart vs a scatter chart for this, but I have the same problem in both)

E11 through E24 contains numbers and a few errors (#N/A) that need to persist (the errors need to show).
E10 needs to show the average of the numbers that are in E11 through E24, and just ignore the errors.
I have many columns like that - where the errors need to show and I need to show an average of the number/values that do appear, ignoring the errors.

TotHCInv.Value = WorksheetFunction. Sum(KRInv, PBLInv, CRInv, PVInv)
If i >= 34 Then CPSCtphRMA.Value = WorksheetFunction.Average("G" & (i - 30) & ":G" & i)
The first line runs properly, but the second line bugs out with the error message "Unable to get the Average property of the WorksheetFunction class". I can simply do the math, but I thought that using the worksheet function would be easier than summing and dividing. I'm curious, though, as to why I can't seem to use the Average function.

I am attempting to calculate Grade point averages for my students for all classes. There are 5 columns of grades to be considered. I frist assign values of 0-5 to the grades then average the points. My problem is that I want the AVERAGE to ignore the zero but it calculates it as well. (I enter a 0 if I have no grade for that class.) I have tried the{ } to make it an array formula but this also did not work. Here is what I have, can anyone help?
=SUM(AVERAGE(IF(AND(L2>89,L2<100),5,IF(AND(L2<90,L2>79),4,IF(AND(L2>69,L2<80),3,IF(AND(L2<70,L2>59), 2,IF(AND(L2>0,L2<60),1,0))))),IF(AND(T2>89,T2<100),5,IF(AND(T2<90,T2>79),4,IF(AND(T2>69,T2<80),3,IF( AND(T2<70,T2>59),2,IF(AND(T2>0,T2<60),1,0))))),IF(AND(AB2>89,AB2<100),5,IF(AND(AB2<90,AB2>79),4,IF(A ND(AB2>69,AB2<80),3,IF(AND(AB2<70,AB2>59),2,IF(AND(AB2>0,AB2<60),1,0))))),IF(AND(AJ2>89,AJ2<100),5,I F(AND(AJ2<90,AJ2>79),4,IF(AND(AJ2>69,AJ2<80),3,IF(AND(AJ2<70,AJ2>59),2,IF(AND(AJ2>0,AJ2<60),1,0))))) ,IF(AND(AR2>89,AR2<100),5,IF(AND(AR2<90,AR2>79),4,IF(AND(AR2>69,AR2<80),3,IF(AND(AR2<70,AR2>59),2,IF (AND(AR2>0,AR2<60),1,0)))))),-1)
I know it is huge. The syntax is correct. It calculates the average, but always for all 5 columns. It will not ignore a 0 in a column.

I'm using the formula =AVERAGE(B16:L16) to give me the average.
However I have a couple of problems with this. Firstly I would like to exclude the value zero from the average. Secondly to also ignore the lowest and highest values.
Example, if the values in the cells are 0,1,2,3,4,5,6,7,8,9,10 then the current result shows 5, by ignoring the 0 and lowest value 1 and highest value 10 the average should be 4.5.

Ok, I for some reason just cant wrap my head around this. I need to to get the average time per call of two rows, but they are based on how many calls taken.
so in one column i have 50168 calls taken at 4:21 seconds per call. and in the next row i have 597 calls taken at 5:20 per call. I need to see what the new average will be with them combined, and I need it to display in m:ss form.

I need to sum data from the most recent 12 months. For example, on June 1, 2007 I want to find the total from June 1, 2006 to June 1,2007. On the 1st of the next month, July 1, 2007, I want to calculate the total from July 1, 2006 to July 1, 2007. I don't need to keep the total from month to month (on July 1, 2007, June's data is obsolete.)

I am working on yet another worksheet. To simplify the task, let's say I have to columns Date and Amount (several hundered entries). I need to be able to sum the first 60 consecutive months, that do not equal 60. Is there a way to use built-in excel formulas to do so, or would I have to create my own formula. I'm trying to stay away from a macro that is run manually.

I need to be able to calculate age in months, and round whatever remainder to the middle of the month (.5). I am calculating z-scores and percentiles for in a childhood obesity project. The DoB and Date of measurements must be converted to read anything from 142.0 to 142.9 as 142.5.
This value will be used to look up the the appropriate LMS (Box Cox, Median, and Standard Deviation) in another excel table. I have to be able to compute age in months so 142.5, 143.5, 144.5, 144.5 etc. It is just not rounding off to the nearest half month.
