# 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.

Below is the table:

I have created a table for a business to monitor all income and expenses within a financial year of that business. This table contains raw data for example, date, income/expense, wholesale amount, retail amount etc. So when the business makes a sale for example I enter in the date of the sale, type of sale, wholesale and retail amounts etc, and i do this for every sale I make.

What i need to do is figure out a way to calculate the average monthly and weekly income to date so as the financial year continues and i make more sales i will continue to enter more data into this table and it will automatically adjust to the new weekly or monthly average income. This way i always have an actual and live average for every cent the business has made as the year progresses and i can use this to budget for the business. I would also like to know what the income is for the current week or month. that way i can say for example on average the business makes $4000 a week and in this week it has made say $5000.

I have a pivot table that summarizes expenses (cash advances, cashe remitted, etc.). The issue that I'm having is the way the data is displayed on my pivot table.

When I adjust the custom calculations to "show data as Running Total in MONTH" I get the desired outcome on my row totals, but I do not get the correct figures on the actual data within the Pivot Table. When I remove this custom calculation and just "sum by value" then the data is correct, but the row totals are not.

In a perfect world I would need the values to sum by value, while the row totals are set to "show data as running total in MONTH". I'm not smart enough to figure out how to produce both.

I've got data in E4:I4, Monday - Friday.

What I need to do, is add the total of those 5 figures in a total, but then clear the data in those 5 days.

Then when I input the data for the next week in to those days, I want it to add to the previos week.

So basically;

In week 1 the 'Total' is just week 1

In week 2, the 'Total' is week 1 & week 2'

I will only be going up to week 5. (only week 5 once in a 3 month period, so 2 4 weeks and a 5 week)

I assume there's a database (or pivot table?) solution for my task, which is to detect the days, weeks and months within a very long table, and obtain the totals of the data therein.

See attached worksheet.

I am to the end of my wits - or maybe it's impossible to do the following with formulas?

I have the data like this:

Column A: Date (which is basically the date for the beginning of weeks)

Column B: Month of the date in Column A

Column C: Year of the data in Column A

Column D: Weekly data.

A: DateB: MonthC: YearD: Weekly data

12/11/200612200619

12/18/200612200644

12/25/200612200650

1/1/20071200741

1/8/20071200737

1/15/20071200741

1/22/20071200741

1/29/20071200741

2/5/20072200732

2/12/20072200736

2/19/20072200740

2/26/20072200735

Maybe it's because it's Friday night, but I just can't invent how to do the following:

Create a new column E that would contain the monthly sum of ColumnD across all weeks of this month - but entered only against the first week of that month (that is currently in Column A)

I.e., in my example it should be:

113

empty

empty

201

empty

empty

I'll use following as an example.

I work for a supermarket, I receive many fruits per day and I want to see what percentage of them are bananas, apples, oranges, watermelons etc.

Are there any templates of pie charts and bar graphs that I can use for this that will show the percentage of said fruits daily, weekly and monthly?

I have the following setup:

52 weeks of 2010 cost with the following structure:

week number | wk1 | wk2 | wk3

week ending | 1/10/2010 | 1/17/2010 | 1/24/2010

weekly cost | 57,000 | 35,000 | 42,000

I want to be able to use the above data to present a summary, but instead of weekly, list the data on a monthly basis:

month | Jan | Feb | Mar

monthly cost | wk1-4 | wk5-8 | wk9-12+3days wk13

Any way to set this up automatically instead of having to split the weekly data as many months share the same weeks?

I have an excel 2007 script that downloads daily stock data and prices. I do analysis and graph the data.

I would like to keep the download the same, but modify my analysis so as to obtain weekly and/or monthly data.

I am sure this is commonly done, and is not rocket science, but so far I am baffled as to the procedure / algorithm to do this.

I can't seem to figure out to easily aggregate & automate a series of weekly values (ie. forecast volumes by a specific part number) into vertical monthly summaries, by product.

Here's the before picture:

column A column B column C column D column E column F

Part num 1/1/2013 1/8/2013 1/15/2013 1/22/2013 1/29/2013A

100 100 100 100 100B

150 150 150 150 150C

200 200 200 200 200D

250 250 250 250 250

The output after manually doing this would look like this:

column A column B column CPart num Date QuantityA

Jan-2013 500B Jan-2013 750C Jan-2013 1000D Jan-2013 1250

We have a weekly "On-Time" report that shows early, late, on time, or no data. Each week has a total percentage of early, late, on time, or no data deliveries. I now need a monthly total on a seperate worksheet, but for some reason I can not get the percentages to total correctly. I am attaching the spreadsheet.

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.

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 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 52 week rolling forecast that I would like to have displayed in each calendar month that it corresponds to. I have come up with a solution where it does lump the data together into months but it is not a smooth lumping of the weeks as some weeks cross over from one month to the next. Is there a way to lump each week into its respective month. My current solution places in some months 4 weeks worth of data and in other months 5 weeks worth of data. Attached is the spreadsheet that I am using. The tab "Weekly Sales" is the 52 week data which has specified the exact dates on the calendar that that week represents. The "Monthly Sales" tab has the 12 week data which has specified the exact dates on the calendar that that month represents. I've tried SUMPRODUCT but that is giving me 4 weeks in some months and 5 weeks in others.

I have a sales level that I need to track...My rolling 12 months' sales must be $85,000 and my currently monthly sales must be $7,000. I have a sheet that tracks the $85,000 and tells me what I need to achieve that, but I haven't figured out how to include the $7,000 monthly minimum....

The chart below is what I have. So for example, this month it's telling me I only need to sell another 3016.46 to hit the $85,000 rolling 12, but I actually need to hit $4821.79 to meet the $7k minimum.

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'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

I hope this question has not been addressed but the closest I can find is in this link:

I am now a commission based contractor who started earlier this year & I want to be able to calculate my current average weekly income which should fluctuate greatly. I have a spreadsheet that works out what my current to date net income is but can't figure out how to break this down to a weekly avarage. My basic guess is that I want to take the figure provided and divide it by the number of weeks from "stated start date" to the current date (but on a divided by 7 basis?) to get my average weekly net income.

I am sure this is pretty simple for you all so I hope I am not wasting time it's just that if I try figure it out I am using something like WEEKNUM & that will fail after the next new year. -Although it would be better to base it all around the financial year if that can be done?

I have two time series which span several years. The first series measures stock levels on every Friday (52 values a year). The second series measures the price level every weekday (260 values a year).

I'd like to condense the daily data in to a weekly average, can I do this easily? For example, I could manually use the Weeknum function to calculate the week number of each daily price data, then find the average daily price for each week, thus giving me 52 values which I can compare to the weekly stock series. Is there an automatic, fast way of doing this? Alternatively, I'd be happy to settle with a monthly average. Is this possible via macro's or does VBA need to be used?
