Auto-updating Formula For Week Over Week Change?

Dec 11, 2013

I was wondering if there's a way to add a formula to calculate week over week % change automatically every week when I enter in new data. see the attached excel file for reference.

What I would like to have is the ability for the formulas in c5 and f5 to be able to auto-update to the newest week and the previous week's data instead of manually having to update it each week. So if I were to add a new row with data for week beginning 12/2, the formula in c5 and f5 would automatically update to calculate the week over week variance. I tried researching prior to asking the question on this forum, and I think it may be possible to do it using the index match function, but I'm not sure how to apply it in this case.

Auto Open Macro To Find Correct Week Tab & Day/date In 52 Week Worksheets

Jan 19, 2010

I am new to VBA & not sure of the full understanding of code copied from a workbook which worked on the same principle but with Monthly (12) tabs. I thought if modified to show weeks, the macro would be able to locate the current week tab & day/date within - but upon opening, the cell stops at WK19 & column O - rather than WK43, Column N (which changes daily).

Sub Auto_Open()
week(1) = "WK1"
week(2) = "WK2"
week(3) = "WK3"
week(4) = "WK4"
week(5) = "WK5"
week(6) = "WK6"
week(7) = "WK7"
week(8) = "WK8"
week(9) = "WK9"
week(10) = "WK10"
week(11) = "WK11"
week(12) = "WK12"
week(13) = "WK13"
week(14) = "WK14"
week(15) = "WK15"
week(16) = "WK16"
week(17) = "WK17"
week(18) = "WK18"
week(19) = "WK19"
week(20) = "WK20"
week(21) = "WK21"
week(22) = "WK22"
week(23) = "WK23"
week(24) = "WK24"......................................

I have a comparison model that looks at two weeks of data. I am trying to get around the deletion and insertion of records week on week. With the code below, I can currently find and correct the deletions and insertions to the list, and then resort the list so that the comparison will work.

Week Number Caluclating Hours For Week

Mar 6, 2010

I have a running time sheet daily. It has 2 columns for Labor and 2 columns for travel
i.e. travel From / To 1300-1400 calculate 1 hour then travel home 1600-1700 1 hour this is calculated by the date entry 01/02/10 I have another calculation that tracks by the date i.e. 01/02/10 then Next job which all works fine.

The problem becomes how do I calculate a weekly total labor and travel by the date So added another column called weekly hours labor and use the Weeknum to determine which week is which day/date so the first Monday in January 2010 is week 2

2 problems
Having many multiple day / date entries are the same date x 7 days Monday Sunday
(Relies on the date entered and the weeknum) 01/03/10 each line is complete however the dates carry over as does the time

When trying to calculate each row x 3 same date time then the value will be incorrect I need to calculate
Say 9.5 hour labor from the date 01/03/10 not 28.5 hours and then calculate the total weekly hours
01/03/10, 9.5 hours labor, 3 hours travel
01/03/10, 9.5 hours labor, 3 hours travel
01/03/10, 9.5 hours labor, 3 hours travel

i do have work and travel times for each job on the same line (separate columns) but I display the total here by date to summarize the totals
i have tried sum products and sumif to avail. I am using Windows XP SP2 with MS Office 2007

how do i calculate weekly hours by date and weeknum ?

Total Work per day

Total Travel per day

Daily....................

Formula For Week # Of Month

Mar 12, 2008

what is the equivalent command to WEEKNUM if I want to properly calculate Week # of Month?

For example (Sunday being the first day of the week):
January 5th 2008 = Week 1 of January
January 6th 2008 = Week 2 of January
February 2nd 2008 = Week 1 of February
February 3rd 2008 = Week 2 of February

WEEKNUM perfectly calculates this, but it is applicable for the whole year.

Formula To Get Date From Month And / Or Week

May 30, 2014

I uploaded an example file.

Now, what I need to accomplish is that the D1 and D3's in sheet 2 need to result in a date next to the correct country (the date (in full) must be the first monday of the correct week). I find it quit difficult to do this because in sheet 2 you have once the country name, but several possible dates. So in sheet 1 there must be a date for every D1 or D3 but under each other.

The second problem is that I need to accomplish to get a "x" in sheet 3 under the correct month where there is an D1 or D3 in sheet 2 (week).

So I need to go from a week to a month and this can be for one country 1, 2, 3 or even more months (it depends from the D1 and D3's in sheet 2).

Sum Formula: Count Of How Many Gallons Of Gas I Put In Car Each Week

Mar 25, 2009

I need to be able to keep a running count of how many gallons of gas i put in my car each week. Each week is one column. Column A is where i want the total to show.
column B,C,D,E...etc is where i put the numbers in this is all in row 1 for now.

currently i have =sum(B1:BB1). But something is not right because it is not adding the numbers together it will only add what is already there not any numbers that i put in after the formula is made. Do i have the wrong formula or something else wrong. My goal is to see how many gallons i put in at the end of the year, month, quarter, and so i have several other reason for this info.

Changing Cell Formula Each Week

Oct 3, 2006

I have a sheet (sheet2) that this week has the formula
Cell B2
=Sheet1!D2
Cell B3
=Sheet1!B2

Next week I want the formula to be
Cell B2
=Sheet1!F2
Cell B3
=Sheet1!D2

And so forth.

Each Column has the Week ending date (a sunday) in Row 1. So D2 represents this week and B2 Last week, until next week when D2 becomes the 'last week' and F2 becomes the this week.

The inbetween letters contain another set of data for those weeks so i will apply the same formula to these.

Excel 2003 :: Calculate Formula For Third Value Of Week?

Nov 9, 2012

On a excel sheet I've got columns, each column represents a weeknumber. I want to calculate the so-called 4 wk average for each row and for each week and this is the formula I use:

(value*Tvalue)+(value*Tvalue)+(value*Tvalue)+(value*Tvalue)/(Tvalue)

(this is not the actual formula but simplified, that's not really important).

It's the checks that make things a bit more complex. If a value of a weeknr is zero, skip it, but if the next value is also zero, just skip the formula alltogether and make it a zero (or text like "false"). So another thing that has to be accounted for is that if a value is zero, the next weeks value is taken instead.Example (see included file):

I want to calculate the formula (mov 4wk avg) for the third value for week 12, which will make the formula

(0.2*6)+(0.3*6) now there's a zero on week 14 so I skip it, then formula will be:
(0.2*6)+(0.3*6)+(0.6*6)+(0.9*6)/(6).

Right now I'm doing this in VBA with a lot of variables and a lot of if statements.Is there an easier more effective

I know the example sheet is a 2007/2010 version but I need to accomplish this for 2003.
