Prorated Monthly Invoices With Variable Billing Days.

Hello everyone I'm new here but hopefully I can get some help with this question and of course be happy to help anyone that I can with my limited knowledge.

I need to show monthly invoice charges based on a bill cycle date, a service start date, and a service end date.

I will provide monthly rate for a service (variable on type of service) and will provide the start and end dates (changing for various services) as well as the bill cycle end day (the same for every account but may change from one account to the next so this being a variable in the formula would be great - could be 12th day of month or 1st day of month or whatever as it may be.) I've been able to accomplish the formula and have it work great for monthly invoices as well as total for a given time period EXCEPT the following cases:

The bill cycle does not start on the first of the month, and so the service start day() value may be < or > the billcycle day() value.

The start and end dates may be in the same month which causes an error in the calculation of the "in between months" when calculating the total.

Any ideas? Thanks.

I am trying to figure out how to write a formula to figure out production cycle time.
We will be building 8 "widgets" a day.
We will work 10 hours a day.
There is a 20 minute break at 9:20 am.
Production shuts down for lunch 30 minutes for lunch at 12:30.
Production starts at 6:00 am.
Here is what I can do.
Production cycle time = (10*60)-30/8 or 71.25 minutes
If we start at 6:00 am, the first scheduled cycle completion time = TIME(6,0,0+71.25/1440)

My problem is when I am trying to use a logical "IF' statement to account for the 20 minute break or lunch and still calculate the end of each cycle time through the day I receive a number of error messages.
This is the formula I am trying to make work. I have the cell the formula is in, formatted with a "mm,ss" format.
=(IF(D4+G1/1440>9:20,(D4+G1)/24,(D4+G1+15)/1440))
I have included an attachment to help (a picture is worth a thousand words).

Any help will be greatly appreciated.
I have bought a number of books in an attempt to figure this out, and I am still stumped


This formula is supposed to calculate difference between today and date hired to give years and months of service. Works fine for all except if the person was hired in year 2000 then this formula shows 110 y. Any one know how to fix this? or have a different formula that works.

=DATEDIF(E21,TODAY(),"y")&" y "&DATEDIF(E21,TODAY(),"ym")&" m"

Thanks

I was able to convert start date and and end date to the number of days
inbetween the two dates. Does anyone know how to then convert the number of
days into months?



I have a sheet which has the start, stop and time taken for lunch breaks.

I want to calculate the total time worked such that i have the hours worked. So if i worked 7 hours and 30min then the total time would be 7.5hrs. But i am not sure how to take into account the lunch break time (see enclosed sheet).

anyone have any ideas?


Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin


Hi Guys,
I need help....I am working production scheduling with Start and End time but there is a lunch time and tea time. Is there any formula to calculate Start time to End time with excluding lunch time?
Here is example :

Lunch time :12:00pm to 1:00pm.
Duration Process :6 hours.
Start Time (8:00am)
End time (5:00 pm)

I need a formula to calculate from Start Time 8:00am and what is the End Time? with 1 hour lunch time...

Thanks,

Newbie here and I don't know where to start... I'm trying to set up a macro to when data is pasted to a TEMPLATE worksheet tab it will automatically copy and paste data to another sheet based on the month value.
For example:
If data contains 06/01/2011 in cell A1, then data needs to be pasted to "Jun" worksheet within the same workbook.

Can someone assist or can give some direction? Thank you


Happy Day to all,

Can you please help me,

A1= time in
B1= time out
C1= time in
D1= time out

I want to calculate the late and under time,
Office start at 9:am w/30 mins Grace period,
The break time is one hour only, please include over breaktime in calculation.
End of office hours 6:00 pm, strickly no over time


I am looking for assistance in having one cell in a text format equals another cell that contains a time value in hh:mm format.

For example: Cell A1 has a time format (hh:mm) value of 04:00; which is the Start Time. I would like cell D1 to have a text format value of "04:00" (result is dependant upon what is entered in A1). I would duplicate the same formulas to reflect Stop Times in other cells.

My final result is to have another cell (F1) use the Concatenate formula to have the Start and Stop time shown in one cell as "04:00 - 12:30". The times would change based on the Time formated values entered into the Start and Stop time cells.

I have researched this in the board and found many excellent ways to do the opposite, but not convert Time format to Text format. Any assistance is greatly appreciated.

Dear Sir,

If any one could give me a solution for this its will be a great help for me.

I am working in a bank and on every day we receive Month to date data of Loans and advances made by every branch with Region wise total and manager wise total. With Sum of loan and count of loan. In our MIS format the in A coulum branches are sorted and listed in a sequence with sub total Region. I have data where if if do the pivot and change the data the out put should be displayed accordingly in the MIS format. Can any one help me how can we do this or is there any other office addins/softwares are available if so the data is changed on a daily basis and if we do the pivot it will automatically copy the data to the MIS format.

Thanks.


In Excel I have been trying to find an easier way to calculate a time
difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00

How would you formulate an equation to determine the duration of time or
differnce between the start and end time?



From limited experience I know that excel calculates dates via serial numbers.

I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)

I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.

What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?

Hopefully a simpler question for your experience level than mine.


I have a graph with various information in it. One is a line graph that tracks hours used in that department per month. The problem is that when it gets to the last month, and there is not yet data for future months, the line goes down to Zero (leavin this big diagonal line that makes the data look funny). I need this line to stop on the last month there is data for. (I do not manually enter the data, it is a formula that I do not wish to delete.) I know I can manually move the data that the line is pulling to make it stop on the last month, but I have a graph for 36 different departments and that's a pain to have to manually adjust 36 graphs each month. Is there a way to tell the line to stop if there is no data? Thanks!!

A previous poster explained what I also need; there were no responses,
so I thought I would try again.

Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.

Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."

Thanks very much.




I'm trying to format a worksheet to show how many days overdue certain tasks are, and running into a couple of issues. The sheet is set up with Due Dates in Column A, Days Overdue in Column B, and Date Completed in Column C. My first thought was just to use as simple a formula as possible in Column B =Today()-A2. This worked alright for tasks that already had Due Dates assigned, but if Column A was blank I'd get a high number in Column B. I also realized that tasks will continue to show as overdue even after I enter the completed-on date in Column C. Is there a relatively simple way to tackle this formula? Thanks in advance for suggestions. (I've attached an example with the column headings I want to use.)


Good afternoon!

I'm working with Excel 2003 sp 3 on Windows xp.

I have been banging my head trying to jar loose the formula to calculate man days where 1 equals 8 hours. I have one that was given to me by a coworker:

=INT(Q3/8)+(((Q3/8)-(INT(Q3/8)))*0.8)

That calculates man days from total hours. I need a formula that will total man days and return the man day answer. Example:

weekending 12/25 = 16.2 which is 16 man days and 2 hours
weekending 1/1 = 24.7 which is 24 man days and 7 hours

Total = 41 man days and 1 hour

I have also been asked if there was a way for a number to be entered into a spreadsheet and automatically put in order without a macro or "pushing a button".

Any advice is greatly appreciated!

Happy New Year!

How do I calculate the number of batches per hour? Here's what I have so far:

Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")

as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.

HI...can anyone help me with a formula for aging data in days (to be aged based on current date vs. for eg., Invoice date)
