Average Daily Data By Month

Jan 15, 2009

I have a workbook with two sheets - DATA and SUMMARY.
DATA has two columns - date and data_value. Data will be added to this sheet on a regular basis

SUMMARY has two columns - month and average

In the column for average I would like a formula to calculate the average of data_value for each month without having to manually determine the range for the particular month.

Daily Average Based On Day Of Month?

Mar 2, 2014

I am performing a given exercise every day in the month of march. I have the dates all lined up in my spreadsheet, with the sum at the bottom. What I want to do is have another cell that will give me my daily average of performance. For example today is the 2nd and I have performed this exercise 360 times, making my daily average 130 per day. If I performed 200 of the exercise tomorrow I would have a grand total of 560 repetitions making my daily average roughly 186 per day (the day, march 3 divided by the number of repetitions, 560) and so on and forth.

I need a formula that will automatically calculate that daily average as I progress with the month. But I want the calculation to stop at the end (i.e. I don't want it to continue as the year progresses, meaning the divisor keeps going throughout the rest of the year). Basically, I guess, I am looking to fill in the daily repetition and the divisor to increase each day as I do so. My average is to be displayed in cell B36, so today my formula should read (=2/B36) and on March 31st the formula would be (=31/B36).

Average Daily Values

Sep 14, 2009

I have a table of data covering the last 9 months based on values automatically collated from 15 minute intevals.
The date/time is in column A (01/01/2009 00:00) with the data collected in column D.

My wish is to get the average daily data from column D and I am slowly losing my head!!!

Is there anyway of getting a formula to auto-average the daily values bearing in mind there are currently 96 daily entries.

I have tried converting the first 5 digits of column A to numeric (i.e. 31894 for 01/01) then trying to write a formula saying =average(D1:D24577,if(range="31894",1)).

I can now see a simpler way but am so confused after an hour or so of trying.

Each day has 96 readings so I need an auto adding formula. average column cell A would say =average(D1:D96).

Is there are way to have the cell below auto-update itself to look at the next 96 values and so on and so forth?

Monthly Average From Daily Data

Oct 28, 2011

I have data in the following format (columns A & B):

Code:
Day Value
1/1/2002 2.1
2/1/2002 4.8
3/1/2002 0.1
" "
" "
" "
31/12/2011 5.2

I'd like to be able to write a formula so that I can get the daily data averaged over each month, e.g so that I have something like:

Code:
Day Value
Jan 2002 3.3
Feb 2002 4.3
Mar 2002 3.1
" "
" "
" "
Dec 2011 4.2

I'd like the data in monthly averages so that I can graph them. I have read about array formulas and averageif statements, but I can't seem to combine them to make them work.

Formula For Average Daily Balance

Mar 30, 2005

Am trying without success to create a formula to calculate average daily balance from a ledger that has a variable amount of entries per month. The variability of # of entries has me stumped. For example:

date, amount
1/1/2005, 10
1/5/2005, 1
1/10/2005, 4.65
1/18/2005, 7
1/22/2005, 20

Aver Daily Bal = 23.78. and I can get this easily manually, but I'd like a more automated solution. I'm trying a sumproduct angle, to no avail.

Summarize Daily Data Into Weekly Average

Jan 17, 2009

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?

Calculate An Average Daily Expense Cell

Feb 6, 2009

I've set up a simple spreadsheet to keep track of my food expenses every month. The first column is for the date, the second is for the daily total expenses and then the next three columns are where I add the data which is then calculated into the daily total column.

I also have a total at the bottom for the entire month. Now what I want to do is I want to also have underneath the grand total, a cell which keeps track of my average daily expenses. Basically I want to divide the total expenses by the number of days which I've entered data. Now normally this would be fine but because I've applied the formula to all the cells in the expense column, it automatically lists every day as "0" rather than leaving it blank. So when it does the average calculation it's dividing my total by 30 days rather than by only the 7 days I have data for.

Average Daily Balance - Recursive Equation For Calculating Interest

May 21, 2013

I create this spreadsheet as a loan schedule using average daily balance method. (1/payment is constant, fortnightly 2/interest is 5.5% per annum)

In the interest column, at the beginning of each month ( when the day is 1) the interest will be added up from calculation of previous month daily balance.

My idea is that at interest column(let start at 1/08/2013) if (day(A49)=1, average the 30 or 31 cells above E49, 0).
I will manually make adjustment for February where 28 or 29 days applicable.

Daily Worksheet Macro - Make Copy Of Template For Each Day Of Month?

Dec 22, 2011

We have a workbook that we create each month that has one worksheet per day of the month, labeled 12_01_2011, 12_02_2011, 12_13_2011...etc. The pages are an empty template with formulas and fields in place that we simply copy and paste the results of an SQL query into. Presently, we are copying the page manually several times over, and then manually renaming the pages with the new dates for the upcoming month.

So, here is my question. Macro that I might use that would:

1) Make a copy of the template for each day of the month.

2) Label each page in sequence with the dates for the upcoming month.

which basically looks at the Month and Year in reference cells then looks through my data on a sheet called DSA..

I have a colum on the DSA sheet AX5:AX10000 where there is a number

I want to be able to calculate the average of these numbers but only if the conditions in the above formula are met.

For example, if the month was MAR 2009 then i would only have the average of numbers present in Colum AX on the DSA sheet for March 2009.

Formula For Rolling 12 Month Average?

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?

Formula To Return Average Days Between Two Dates In A Given Month?

Jan 13, 2014

I have a workbook with two sheets. The first has a list of job positions open, columns designated to stages in the employment process and in these columns, my staff enter the dates that they completed a particular stage.

"Position | Date Opened | Stage 1 | Stage 2 | Stage 3 | Stage 4"
Pos 1 | 01/01/2014 |02/01/14|03/01/14|07/01/14|09/01/14

This has a great number of entries and they are increasing and decreasing every day depening on the amount of jobs available.

On the second sheet, I am trying to set up a table which shows the average working days it is taking to complete each stage, divided into the months in which the job position was opened (i.e. for positions opened in january, the average completion working days for stage 1 was X amount of days etc...)

I have tried using =IF(AND(Logical, Logical),TRUE,FALSE) but this doesn't return any info as the logicals will always be false. I tried the OR function, but that requires only one of the criteria to be true to return a value. What I need is for the formula to return a number of days between two dates, ONLY if the opened date falls in one month.

Average With Conditional Month, Year And Date Range

May 8, 2008

I collect unique prices each day. I am trying to find a way to determine the average of the numbers collected from the 21st of the previous month to the 20th of the current month. This formula will need to calculate for multiple months and years. So for example, I need Feb2008 average-which would be the average of numbers found between Jan21-Feb20, I then need Mar 08 average which would be data from Feb21-Mar20 etc. My spreadsheet is setup with the first column having the dates (ex. 01/01/08, 01/02/08 etc) and the second column containing the value for that particular date ($2.85, $3.00 etc).

As the number of days between the 21st and 20th change each month, I just can't seem to find a way to do it without a whole lot of manual effort.
