Rolling Sum Fomula
Aug 13, 2009
I need a formula to give me a ROLLING SUM of the last 12 entries in a column, to give a rolling year sum.
Each month a new number would be added to the column at the end just before the rolling sum calculation.
The formula then would sum the new entry plus the preceding 11 entries.
E.g. Cell values as follows: A1=10, A2=6, A3=3, A4=9, A5=4, A6=5, A7=13, A8=2, A9=7, A10=1, A11=14, A12=5
Say the sum is in cell A13, the sum=79.
A row is inserted above A13 and 7 is entered.
Now the sum calculation is in cell A14 and the calculation is from A2:A13 which equals 76.

I would like to copy one cell formula to another but i would like the constant to remain intact. When i pull it over to another cell there is an incremental effect.
from:
=SUM(LEN(B9:B300)-LEN(SUBSTITUTE(B9:B300,B4&","&D8,"")))/(LEN(B4&","&D8))
to
=SUM(LEN(B9:B300)-LEN(SUBSTITUTE(B9:B300,B5&","&D8,"")))/(LEN(B5&","&D8))
But i want it to be either
=SUM(LEN(B9:B300)-LEN(SUBSTITUTE(B9:B300,B4&","&D8,"")))/(LEN(B4&","&D8))
or better still simple increment just value
=SUM(LEN(B9:B300)-LEN(SUBSTITUTE(B9:B300,B4&","&D9,"")))/(LEN(B4&","&D9))

I have a spreadsheet which uses MS Query to import data from our MRP System. This Spreadsheet has all new orders and qtys required per sales order etc. Each Part number may have several sales orders and different qtys for each. I am looking for help to write a fomula which looks the required qty`s for each sales order & part and check another sheet which has all the avaliable stock to sell on it and populate a column next to the qty req`d with what if anything is available.
Both the orders sheet and the stock sheet are MS Queries which refresh at a given interval so cells may change position.
Cutdown Example of Orders Sheet.
Sales Order No. ¦ Part ¦ Qty Req`d ¦
--------------------------------------
1234 ¦ Apple ¦ 12 ¦
6777 ¦ Apple ¦ 16 ¦
7989 ¦ Pear ¦ 4 ¦
cutdown Example of Stock Sheet.
Part ¦Qty in Stock ¦
----------------------
Apple ¦ 12 ¦
Pear ¦ 3 ¦
Now the fomula should bring back the following
Sales Order No. ¦ Part ¦ Qty Req`d ¦ Qty Avaliable ¦
----------------------------------------------------
1234 ¦ Apple ¦ 12 ¦ 12 ¦
6777 ¦ Apple ¦ 16 ¦ 0 ¦
7989 ¦ Pear ¦ 4 ¦ 3 ¦

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.

I am working on a spread sheet and am trying to use rolling averages of the last 3 months. I am using worksheets for each month with a final worksheet containing the 3 mo. rolling average. I tried using a formula with OFFSET and it worked fine if all the data was in 1 worksheet, but did not work for multiple worksheets averaging to another worksheet in the same workbook.

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.

Is there a way to make a VBA code where everytime I run this macro it adds 1 to a cell and keeps a running total?
Example:
E17 currently = 0
Running the macro makes it display 1
Running it again makes it display 2 etc...

I have a column of data (Column A) and I'd like to build first the Average of the first 20 data points (like in an Excel spreadsheet, cell B21 will contain the average(A2:A21), cell B22 will contain average(A3:A22), and so on... rolling).
I looked up on the internet, but I simply don't know how to start with, I mean, how to name the new array and make it rolling.
Then I will need to calculate STDEV for the same interval, and then Zscore ((Value - Average)/STDEV), but I guess it comes automatic once you made the first part.

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 data that is linked and is updated automatically. I am trying to use named ranges for the rolling data for each area and my date range is 5 cells using the Today()-5,4,3,2,1. The dates are rolling fine, but I cannot get the data to update, it stays the same from day to day.
look at this and see what my error is? cookies and kudos(no password on the unprotect)

Alas I need to put more dynamics and fill this data set from other sheets, so I'm putting formula into column A, and this force chart react and insert another category.
In other words I want to have this fill only if data present on different tab(worksheet).
That what I have now:
[Code] ........
COUNTA
Counts the number of cells that are not empty and the values within the list of arguments. Use COUNTA to count the number of cells that contain data in a range or array.

I have an excel sheet setup with several tabs which are organized by work days in a week. (i.e. aug 18, aug 19, aug 20, aug 21, aug22, aug 25, aug 26, aug 27, aug 28, aug 29) Sample file has been included.
I would like to do a rolling total of 1 particular cell (the same location on all the sheets, i.e. cell a2 on all sheets) for the past 4 weeks, and it automatically adjusts itself based on today's date (i.e. today is august 27, it will total everything from jul 30, 31, aug 1, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 18, 19, 20, 21, 22, 25, 26.).
Is it possible to do this?
I am not familiar with VBA or Macros, so solutions using either of these will require some detailed explanation for me to understand how to apply them.

One of our govt. agencies requires that I compute the 24-month rolling averages of the daily average input to a manufacturing process. In this instance, the agency is demanding the rolling average since 2003, so there are a fair number of data points involved. The process control computer can provide me the daily data (attached file contains 30 months of data), but cannot compute the 24-month rolling average.

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:

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

Whenever I add new data I need two cells of the old data to not be counted. This should continue until old data isn’t being counted anymore.
EXAMPLE:
New Data entered Cell C36:E36 (148, 147, 214)
Old data shouldn’t be counted anymore from Cell C67:E68 (137, 152, 156, 94, 117, 158)
Total before New data Entered: 14066
After New data Entered: 13761
This formula is required for a total of 16 weeks or until all the old data isn't being calculated anymore in my rolling total.
I only need one total the three examples are just showing what the total should be calculated.

I need to create a Sum of numbers month to date Rolling. Meaning... if I have a expected number for the month, I need to be able to sum the processed numbers for each day up to the current day excluding any day after the current day.
So the formula would need to sumif the total month numbers UP TO the current day and compare that against the processed UP TO the current day.
Month Expected Processed
April 1 500 450
April 2 500 450
April 3 400 425
April 4 400 450
April 5 400
April 6 450
Month Total

What it is, I have a rolling report for the whole year, each with a score for the week.
However, it needs to show the whole year, but I need a seperate box with a summary of only the last 4 weeks on a rolling basis, ideally this would automatically update depending on the week.

My employer uses a scoring system to give a value to an individual’s sick record in the current rolling year.
Each person, has recorded, the number of sickness occasions and the total number of days in this rolling year period, these details go onto the final sheet where a score is calculated.
At present to get an accurate period, I have needed manually to deduct days to produce the correct time frame, ie 27/3/06 to 28/3/07 or when the sikness carrys on into the folling month.
I have tried without success to modify the rolling year formula, which as it is, will include the whole of March 06.
The formula is
=SUMIF(B5:D49,">="& DATE(YEAR(TODAY()),MONTH(TODAY())-12,1),L5:L49)

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.

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?
