# 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.

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??

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.

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.

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.

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

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

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?

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).

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.

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 my spreadsheet has columns A-H.

A is Date

B is Room Number

C is Location

D,E,F all have numbers results in them.

G is the average of D,E,F for each person

H is group average.

If I want to define a group average in column H where it calculates the average of a group that attended the same location, date and room, for each group that attended would that be possible?

So For Example (Columns DEF left out for clarity)

Date

Rm

Location

G Inidivual Average

[Code]....

So because room number changed it calculated as a different group. Is this possible?

Is there anyway for a chart to show only a certain range, ie the past 12 months, without having to update the range every month?

We need to show our scrap rate over the last 3 years. At the end of every month we add a new line. When we enter the number of pieces scrapped for this month I want the chart to drop the number scrapped in January '07

I am trying to do is create a total of only the last 90 days of entries from a list of $ amounts. Attached is an example. We are going to start keeping track of our cashiers variances but at the top of the sheet we only want to know what their last 90 days of entries equal.

This would be considered a rolling 90 days, so older variances drop off after 90 days, they would still be left on screen but would not effect the main total.

I am working on Project Planning, I need to create the Progress curve for our Project based on Weight Factor every month.

I need to create the Plan and actual curve based on the dates defined in particular activities. Once the activity progress is calculated every month based on cut off date then it will sum product with corresponding WF to get the progress achieved every month. Presently I am calculating the values every month and pasting the values in Chart data every month. I had created the S Curve and attached here.

Now my objective is to automatically calculate the values for the entire cut off date at one time (From Project Start to End). i.e I don't want to do any manual work in the Chart. I will update only the actual Dates in the file, then the curves need to get automatically updated.

1) I don't want to calculate the progress for individual activities, I would like to calculate the overall progress directly.

2) When I change the Cut off date, then the previous values needs to become static.

I am trying to create a list which will summarise information from a dataset depending on two input cells in which dates are inputted by the user. I would really appreciate it if you could have a look at the file I have attached and give me some idea as to what formulae I should be using!

It is important that the position of the output list remains where it is (as ideally I want to draw graphs using the information summarised in the output list.

If your confused now when you look at the file it should make a bit more sense.

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.

Here’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)

Here’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

I have been perusing various Excel sites in hopes of finding a macro or function that can create columns based upon two dates input into specific cells. My ultimate goal is to use this macro or automated function so that when the user inputs the dates, the columns would automatically be created for them, rather than having them do it manually.

ideally, the 'start' and 'finish' dates are named cells and the macro could determine the difference between the two and automatically insert columns to the left of a ' Totals' column.

I've got a table with columns for each day of the month, the second row contains the days of the week (MON, TUE, WED, etc...). I want to have two cells at the end of each line, one for summing the numbers in the working days (mon-fri) and another - for the sum of the numbers in the weekend cells.

The idea is the change the content of the second row every month so that the days of the week correspond with the respective date.

what formulas should I employ to accomplish this task and how exactly to do that?

In my spreadsheet there is a main table that has the following:

Name of Company ABC Fund XYZ Fund

Acme $8888 $9999

Joe Co. $9595 $5555

Now, on another sheet I enter in the company name in Cell A1 and then the Fund name in A2. I want A3 to then be equal to the appropriate amount (name of company and amount in fund). I have used vlookup before but that only returns half of the equation.

I need to name a dynamic range of cells. The only constant is the column - H, and the heading "MRC".

MRC column in a table represents an array formula. Unknown is the row where it is going to show up and the number of rows that this array formula will take. I need to name this range (active cells based on the array formula) but do not know what row does it start with and how many rows will it take.

It is not the last table in column H either but there are 2 empty rows before the next table.

Trying something like that...

=========================

Set aCell = Range("H:H").Find(What:="MRC", LookIn:=xlValues, _

LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _

MatchCase:=False, SearchFormat:=False)

If Not aCell Is Nothing Then

aCell.Offset(1, 0).Select

========================================

That's how I select the first cell in the range. Not sure how to select the whole range and name it ..

ActiveCell.End(1xDown) ?

I have been trying to create a formula (with little success) to calcuate an average figure between two dates i.e.

Column A Column B

01/12/06 40

02/12/06 39.5

03/12/06 39.9

04/12/06 41

I want the average of 01/12/06 and 04/12/06 (or any 2 dates), I can write a formula to pull in the 40 and 41 and have an average of 40.5 but I need it to calculate the average of all values within the range so the end result is 40.1.

If you have some low time resolution data you need to compare with high time resolution data how do you average the high resolution data. For example data that starts and ends a fortnight apart and you want to compare it with data that starts and ends 1 hour apart you need to average the hourly data to do so. I can't figure out how:

So if I had Sheet 1 with hourly data

A B C D E

1 Date, Time, Measurement

2 01/01/2014, 01:00, 62

3 01/01/2014, 02:00, 38

etc....

Then in Sheet 2, fortnightly data

A B C D E

1 Date on, Time On, Date Off, Time Off, Measurement

2 02/01/14, 15:23, 18/01/2014, 12:25, 52

3 18/01/2014, 12:25, 01/02/2014, 14:19, 34

etc....

I'd want to add a new column of data to average the hourly data so I can use the correl function.
