## Excel 2007 :: Last Twelve Months Total Rolling

May 6, 2010

I am trying to add the total values from twelve months sales together, then when i add the next months sales value (month13) it is added to the twelve months total but the first months value is deducted from the total. So basically it is a rolling twelve months total figure that both adds the latest months value and deducts the first months value automatically. i am not sure if this is possible in excel 2007.

## Average From Whole Months Data Taking Exact Date To Start With

Jan 7, 2014

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.

## Rolling Average VBA

Jul 30, 2013

I have a spreadsheet which has data in the format of:

Date
Sales

Monday, 8 July 2013
191

Tuesday, 9 July 2013
180

[Code] ....

I calculate the average of the last four weekdays individually with =Average(A1,A8,A14..) in a cell above them to get a four week average.

Each time I add a new weeks worth of data, I manually adjust the formula to remove the first cell, and include the latest cell with new data.

I'm looking to find out if there is a way I can automate adjusting the formula so it always grabs the last four Mondays (for example)? Either in VBA or a formula.

## Rolling Average

Could you please supply a formula that will calculate a four week rolling average of column B in relation to the dates in column A? I tried using the average and offset functions but can't quite get it to calculate the correct averages.

## Rolling Average 12 Mth

Mar 25, 2009

I'm looking for some help to create a rolling 12 mth average. To explain better I have added a copy of the part of the sheet to help you understand what I am working with.

What I'm looking for is the 12 mth average to show up in cell c26. I have the mths listed in cell A2-A25 and the data I want averaged is in C2-C25

An additional problems is that I only want the 12 mth avg calculated if data in the next mth is greater than zero. Meaning since this month is Mar-09 (which is already collecting data) I dont want to include Mar-09 data yet. I only want to know Mar-08 to Feb-09 average. Once data is returned to Apr-09 then I want the average to show for Apr-08 to Mar-09 and so on. I dont what is better to use vba code or a formula which ever is easier.

Or if someone has a better idea please share.

## Calculating A Rolling Average

Oct 8, 2009

I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below:
...
C9 39.65 653.95 5.28 163.56 99.56 14.49 ... ...
E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ...
G9 111568 298021 12940 31645 181797 36996 ... ....
...

I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?

Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly

## Average Formula For Rolling Range?

Jan 24, 2014

I am trying to create a formula that looks for the last populated cell, counts 12 cells back and returns an average for all of the cells in that range. I know I have done this before with some combination of INDEX and COUNT, but I can't seem to remember how I did it and my experimenting is not proving fruitful.

Attached is a simplified version of the layout I am working with

## Formula For Rolling 12 Month Average?

Mar 16, 2010

See Attached.

The YTD 10 column is fine that will change everytime you update each month. I was wondering if there was a formula I could use for the Rolling 12 month Column.

At the moment it is averging from Mar 09-Feb10 which is correct but when it comes to putting in data for Mar 10, the Rolling 12 month column will obviously not change.

Is there a way of moving the formula along one each time you input data into a new month. So when Mar 10 has been entered the rolling 12 month column will pick up Apr-09-Mar-10 then when Apr 10 has been entered the formula will change again to May-09-APr-10?

## Rolling Average That Excludes Zeros

Dec 7, 2006

I've got a worksheet that has chronological quarterly data for which I'd like to do a 5-year rolling average. The layout is: Column A = Dates, Column B = Values, and Column C = 5-year Rolling Average. My problem is that I want to exclude zero-values from the averaging calculation. I tried the following:

={AVERAGE(IF(B1,B5,B9,B13,B170,B1,B5,B9,B13,B17))}

However, Excel will not accept this formula (I assume an array must be contiguous? Please let me know if that's correct).

## Calculating Rolling Average Ignoring 0 Values

Jun 6, 2014

What I have is a spreadsheet with a whole bunch of sporting data on it. see attachment for an idea of the layout, Stats.jpg

In these data each round a player is given a rating. What I want to do is calculate is the average rating for each player across the last 3 and 5 games they have played. When a player misses a game they get a rating of 0 for the round. I want 0 ratings to be ignored in the running averages. Additionally, games yet to be played have a 0 in the cell and should be ignored. To get overall averages ignoring 0's was simple I used the averageif function, but I couldn't figure out how to use that but only extract the last 3 non 0 values. I currently have data up to round 12, so if a player has played in 12, 11 and 10 then the 3 round average should just be the average of these 3, but if they missed for example round 11 then the 3 round average should return the average of 9, 10 and 12.

The data is set out in the following way.

In column B I have a list of player names from cells B3:B618.

Across row 1 from N1:AM1 are labels "round 1" "round 2" etc.

The ratings for each player in each round are in N-AM and from 3-618. i.e. N3:AM3 contains the weekly rating for player 1, 4 contains player 2 etc.

I would like the 3 round averages to be returned for each player in column L and 5 round averages in column M.

## Calculate Rolling Weekly And Monthly Average

Feb 19, 2012

I am wanting to calculate a rolling monthly average and a rolling weekly average.

The following cells have the headers k2 has Allan, Cell L2 has Bill, Cell M2 has Charlie, Cell N2 has Don, cell o2 has Ellen and Cell P2 has Flora

Column J3 to J14 respectivley has Jan to Dec

The balance of the cells will have the data.

I then need to plot the rolling averages for each person on a gaph as teh months data is filled.

## Rolling Average Based On Current Date?

Aug 21, 2012

I have the formula for calculating a 13 week rolling average, but I need to be able to set goals in the future and still have the average calculate from current and not from future.

I have my dates set up in row 3 (these dates are all mondays, not every day) and my data in row 4. I need the 13 week rolling average to calculate starting from the prior monday and going back 12 more mondays for the 13 weeks. IE: This monday I'm running reports that the info will be entered into the previous week's monday.

Here is the formula that I'm currently using: =AVERAGE(OFFSET(K4,,COUNT(K4:BV4)-13,,13))
The formula works but will calculate the average for 13 weeks prior based on the last cell with data in it. It's calculating the average of the last 13 weeks of next year.

how to make this work without having to remember my weekly goals every week??

## Create Rolling 30 Day Average Based On Dates In Heading

Apr 16, 2014

I am trying to create a rolling 30 day average based on a date in a particular cell. I have 62 columns that I am looking at. We can call A1 7/1/14 and the 62nd column 8/31/14 for simplicity sake. I want to grab 30 values in row 2 as these columns are filled in daily so 8/1/14 takes the average of 7/2/14-8/31. On 8/5, I want 7/6-8/4 so on and so forth. The average that I need has to include at least one averageif stating that only nonzero "<>0" figures should be tabulated (just have business day transaction data but need all dates listed to tabulate 30 days). The range of dates will be fixed every month and info copied to tabulate on the first day.

## Rolling & Average (write A Single Formula That I Can Copy Down)

Mar 2, 2009

I've got a "Date" Column which has every day of every month, and next to that several columns with different types of data to correspond to a particular date.

To simplify this (because there are TONS of dates), I've made another "Date" column that displays only every 5th day. Now what I'd like to do of course is average the corresponding data over five days.

I don't know how to write a single formula that I can copy down that will do this.

I've attached a sample spreadsheet with only one month's data, the stuff I need a formula / code for is in red

## 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......

## Calculate The Average Of The Previous 12 Months

Oct 14, 2009

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.

## Calculate Weighted Average Of Prices For 12 Months

Jul 9, 2012

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

## Count No Of Unique Months For Finding Average

Mar 11, 2014

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?

L/H
Prod type

## Rolling Up Data From Several Sheets Into One Sheet

Jun 23, 2009

I am trying to get data from one sheet to another. For example:

You'll notice on my attached workbook I have serveral sheets that I would like to show on the one sheet labeled Rollup. Now i know all i have to do is copy and paste, but I would rather for the data to automatically update on the Rollup sheet.

## Graphing 12 Month Rolling Data

Jul 2, 2008

I have researched and read multiple threads related to graphing rolling averages per month. I've setup my own but I cannot get it to graph correctly. The x axis will be the days of the month ie. 1-31. The y axis is obviously the sales volume. The legend should be a line graph for each individual month sales. I want the graph to reflect the current month and previous 12 full months.

I used the file user rockycj started for another user in a different thread labeled, "Excel Line Chart - 12 month chart moving with dates ". It was very helpful and I'm trying to get this completed before my deadline. If anybody could take a look and let me know, I would greatly appreciate the help. I have attached the file for reference.

## Macro To Create Unique Rolling Data List

Feb 4, 2012

I need a Macro to create a unique, rolling data list. On Sheet 1, a report is pasted(from outside source) in cell A3(Rows 1 & 2 are headers) on a weekly basis. It is always the same amount of columns wide(138). The number of rows will always vary but will never be more than 500.

Hereâ€™s what I need for Sheet 2:

-Column A should be a copy from Column A on Sheet 1 (data is ITEMS)
-Column B should be a copy from Column BH on Sheet 1 (data is QUANTITY of items)
-Column C should be a copy from Column BI on Sheet 1 (data is PRICE of items)

Hereâ€™s the challenge (when the new report is pasted on Sheet 1):

-Sheet 1. Find new ITEMS not on Sheet 2 and paste them at the end of the report on Sheet 2 along with their QUANTITY and PRICE
-Sheet 1. Find any ITEMS already on Sheet 2, then update new QUANTITY and PRICE from Sheet 1 onto Sheet 2
-Sheet 2. Leave ITEMS alone that are now missing from the new report on Sheet 1

## Conditional Format - Dates Greater Than 18 Months And 24 Months?

## Add Months & Return Decimal As Years & Months

Jul 31, 2007

I am looking for a formula that will add months and return the year. E.g. if I add 1.05 and 1.07 I should get 3.01. i.e. 3 years and 1 month.

## Sum 3 Months Together With The Data Given

Aug 7, 2009

I am trying to find a way to sum 3 months together with the data given. (See attched file). Basically a quarter report. Right now the months are in text format (Jan, Feb, Mar, etc). They can be numeric instead of text if it is easier.

## Moving Old Data By Months

Sep 4, 2009

I have 6 rows of data with 12 columns. The first row of data consists of the 12 months and the order changes with the current month -1 listed first. The first column of data is updated from a separate sheet. When the first column is updated I would like the old data to follow the month it was originally listed under until that month becomes the first month again.
