Excel Average Dates - Calculate Percentage For Each Column Individually
Feb 11, 2014
I have an excel spread sheet with columns of dates I am trying to get an average formula that counts dates less than a year old as 1 and blank cells and dates greater than a year old as 0 and then gives me a percentage. For example I have a column with 10 dates all less than 1 year old I would get 100% but if I had a column with 8 dates less than a year old and 1 dates older than a year, and 1 blank cell, I would get 80%
Is this possible at all, or do I have to calculate the percentage for each column individually.

I want to display the percentage of occupancy for each month for condo rentals.
I have columns with dates that represent bookings throughout the year. check in and check out dates to be more precise. (A1 and B1 for example) and I have columns with months Jan, Feb, etc. (C1, D1, etc. for example)
The problem I run in to is that I can calculate the number of days between the dates and the fraction of the year (*12 to get a monthly value, but I fail to understand how I can break that up so that I can populate each month with a correct percentage of the total term.
E.g. A1=1-jan-2014 and B1=20-jan-2014 is an easy one because it only covers 1 month:
formula: =(YEARFRAC(A1,B1,3))*12 gives me 62,47% which I could just use as is for that month.
So far so good, but when the period covers more than one month or when the months overlaps, I don't know how to break the outcome up into the appropriate months to display the correct percentage for each month in its own column.
e.g. A1=1-jan-2014 and B1=20-Mar-2014 gives me a result of 253% with the same formula.
100% for November, 100% for December and 63% for January, which I could somehow formulate to break up over different Months.
But then it gets more tricky. What if the booking starts on a day other than the 1st of the Month?
e.g. A1=5-jan-2014 and B1=20-Mar-2014
The result of the formula (243%) is correct, but isn't sufficient to put the correct percentages for each month in their respective column.
What formula(s) should I use to break down the percentages to match the correct fraction of each individual month?
I attached an example of what I have so far for your review : test.xlsx

I'm trying to figure out if there is a formula I could use that will calculate the average of a group cells in one column based on the condition of another column. It's hard to explain, so I will show an example. All the data is on a one worksheet and I'm trying to show totals and averages on another worksheet. Location, Days
17, 4
17, 3
17, 5
26, 4
26, 8
26, 10
26, 7
On a different worksheet I would want to know what the average days are for each location. So is there a formula that I could use that will look at column A for a specified location number and then average all the days in column B for that location? I'm using Excel 2003 and have tried using the Average(if) but with no success.

I have a pivot that includes customer data and I need to create an average for each row based on the first populated column for each customer. After one month of units appears for the customer, I need to calculate the average going forward, and if there are blanks after that they should be treated as 0 in the average. Below is an example of my description of the pivot.
Jan Feb Mar Apr
Customer #1 1 1 3
Customer #2 1 3
Customer #3 2 2
So, the average for customer #1 would be calculated from Column B to Column E, and factor column D as a 0 in that calculation. Customer 2's average would start in Column C and go to Column E, and factor column E as a 0 in that calculation. Customer 3's average would start in column D to column E.

I'm currently using this formula to calculate the average values in column B where the value in column A ='s E1 eg:
=AVERAGEIF($A$2:$A$21,E1,B2:B21)
Instead of doing this however, I need the formula to calulate the average from column B where the "Date" in column A ='s the year and month I specify in other cells.
Year value specified in: F1
Month value specified in: G1

I have a DATEDIF column which I have used to calculate the age of a group of people from their dates of birth. This has produced results in cells which look like this: Age is 44 years, 1 Months and 28 Days
Where I am stuck is that I need to calculate the average of this column so I get the average of the total group. Is this possible?

I have a pivot table and I created a formula that says:
=jobCompletedDate-jobCreatedDate
and so for example, I have
3/31/2014 7:21AM - 3/31/2014 6:33AM
and that difference is giving me: .03367
I'm not sure what this value represents......the difference in dates, converted to ??

I have been trying to get excel to calculate elapsed time between two dates using mostly what I've read from other elapsed time posts. But I am clearly missing a step. I'm trying to streamline my process for taxes.
I want to take a time in the format of " yy/mm/dd hhmm " example: 1
3/04/24 2245 ( note its a 24hr clock) 13/04/24 2245 would represent 2013 April the 24th at 10:45PM.
------- A --------------- B -------------------- C
13/04/24 2245 ------13/05/24 0900 ---------[display hrs elapsed] <-- currently get #name?
I have custom formatted A and B to yy/mm/dd hhmm and formatted c to [h]:mm
When you enter b-a in column c you get #name?
If its easier to have the date and time into separate columns I can give that a shot, I was just trying to make it as streamlined as possible for copy past.

I'm stuck on the final piece of my macro project. I've attached a workbook with two sheets: sheet 1 is what I currently have, and sheet 2 is what I'd like my report to look like when complete.
On Sheet 1:
- column B is called Supervisor Name
- Columns D-O are months of the year, with either a Yes or No in each cell.
I'd like to write a macro that will:
- Take all unique values in Supervisor Name column, and paste these Above the current table.
- For each Supervisor, and each month, I'd like it to calculate, as a %, the number of Yes mentions in each month divided by the total cells (Yes/(Yes+No)).
Sheet 2 contains the output, in the format I'd like to see it.
Sheet 2:
Supervisor Name
October
November
December
Supervisor 1
8.3%

I'm using Excel 2003 & Windows XP Professional.
I have two sets of data tables. One contains Number, Name & Date. The other contains amounts which those people have paid in 2007, 2008, 2009 & 2010. So in the below Jones has paid a total of $580 over those years, Smith has paid a total of $650 over those dates & so on.
The amounts in 2007, 2008 etc are full year amounts. I'm after a formula that can calculate the amounts for part years based on the dates from C1 to C11 by number (or name).
I've got what I think the results should be (I think with some rounding problems), but my real data has much more data.

I have a column say column B for example that has a list of dates in the format dd/mm/yyyy. I would like a summary at the top of the columns to state how many dates there are for the current month. But I wondered if this was possible based on the TODAY() function or similar. Thus the user would not have to change anything.
So for example at the start of the month it may state 14. Half way through the month down to 6 and at the end of the month 0 for example.

I'm trying to calculate the number of days between dates in column A and B. I've looked at the examples in this site and thought I used the formula correctly, but the cell returns an error message when I type: =DATEDIF(A1,B1,"D")

I have two rows of data representing marks out of different amounts.
E.g.
A1=23, A2=14, A3=50 etc.
B1=12, B2=10, B3=32 etc.
So, the first mark is 12 out of 23, the second is 10 out of 14 and so on. I have a large number of these for at least 250 people. Is there a simple formula that will immediately work out the average percentage for all of the marks above? If so, will it still work if some marks are missing?

I just can't figure out how to create a formula to figure out the average Percentage increase over two figures.
For example:
Amount 1 Amount 2
$17,330,000$20,150,000
Would I use the average function?

I have a simple issue i cannot figure out how to write a formula for.
In A2 i have the number of operations.
In A4 i have the percentage of CPU usage it requires to complete those operations.
I need an output somewhere that will tell me how may operations I can get per 0.1% of CPU usage.

I have attached a file with both a sample section of data on the first sheet and the outcome I would like on the second sheet... I would do it all manually but there are over 200,000 rows in the actual file.
The macro needs to calculate the percentage of sale for each reference number within each part number and move down to the next part number and do the same until it reaches the bottom.

code needed to be able to automatically calculate the percentage needed from one year to the next. I simply need it to automatically create a third column each time the copy old data button is pressed, and I need the column to have the percent increase ((current year - past year)/current year). Hopefully you can understand what I am aiming for. I have the current code below, and I will attach a compressed and stripped version of my workbook.

In the attched sheet, I am wanting to draw data from the worksheet "On-Off" Array $AI$14:$AJ$91 into column AA, while at the same time choosing the closest match to the time. I have managed to get the closest matching time into column AC.
What I am having trouble with is now calculating the number of staff on that break time (column Z) against the number of staff rostered on at that stage "On-Off" (column AJ). I thought it would be a simple division and format as a percentage, however something in it using the extract from the "On-Off" sheet is stopping me, and I cannot figure it out.

I have a row of numbers from 1 to 26 in cells A1 to Z1 representing numbers
'chosen' at random by 500 unique people.
I have another row of numbers representing the 'frequency' that the
aforementioned number was chosen in cells A2 to Z2.
Example:
1 2 3 4 5 6 7 8 9 10 11 ...
10 4 16 9 23 20 61 13 18 43 17 ...
Is there a formula that I could use to calculate the percentage (0%-100%)
that each number was chosen?

I need a correct formula to calculate percentage...mine is not correct
Cell J18 will hold the formula.Range C18:I18 will have values.
C18 will have a value for today,D18 will get a value tomorrow,E18 will get a value 1 day after tomorrow etc..etc..
J18 formula - =sum(C18:I18)/7
If I only has a value in J18 then it will divide that single number by 7.......can a formula only divide by entries in cells....if I have 1 entry then it divides by 1,if I have 4 entries then it divides by 4 etc..etc until thee is 7 entries.

What I have is four columns with data. First column name second column number third column name fourth a number. Trying to get the total of the numbers for the names. So the first and third columns have names in them and they can be in each column or just once in either. I need to get a total column with all the unique names and then their corresponding number (added together if they are in both columns) to display the name and total. The names could be duplicated in each column as we (hopefully) have a lot of the same people coming week in week out.
What it is being used for is a two week and four week revolving attendance. I have a daily sheet one that I am using data filter unique values and then a countif to show me their attendance for the week. Putting it into a totals page sheet with week 1 week 2 etc.
So looking for a way to get all the unique names and their corrorsponding cell value added together to show the persons attendance for two weeks and then the month.
