I have a logbook which already uses a number of SUMIF formulas but have been trying to create one so that totals the number of hours flown in the above mentioned periods. I am attempting to copy the formula and then modify for the relevant column in this case: =SUM(IF(FlightDates<(TODAY()-90), 0, FlightLength))

FlightDates is the named range of the calender date in column A and FlightLength is the named range for total flying in column Z. However even though this forumla works in another situation e.g. tracking number of landings in the last 90 days, it comes up with an error.

I need to calculate a pay back period for a certain investment. Excel has options for NPV and IRR but not for the Pay back period. (PBP). I've tried finding a solution using google discussion groups and some books but nothing helped me out. attached you'll find an example of my sheet. I need the PBP to be calculated in e.g. 5,3 years. but when the figures change it should automaticly recalculate the PBP.

I am looking to calculate compound interest over a period of 10 years.

I am looking at putting a lump sum in at the beginning and contribute in monthly installments for the entire 10 years. How would I go about this.. I know there are formulas there, however I'm not a financial person at all..

Excel formula to calculate period between multiple dates.

Column A has first arrival Column B has first departure Column C has second arrival Column D has second departure Column E has third arrival Column F has third departure Column G has forth arrival Column H has forth departure Column I has fifth arrival

I am creating a timesheet using excel 2003 users enter their shift start/finish time and a break start/finish time. Emplyee's can work night shifts (ie across midnight).

There are penalty rates which apply at different times. I need to be able to work out the amount of worked time that fits into a certain time period. eg. 10pm-7.30am, 7.30am-10pm.

I have a solution based on A clever formula from Daniel Maher that will calculate time within a period. But it doesn't work when the shift goes over two days.

I have attached a spreadsheet to help show the problem .......

I am trying to calculate the average start time for a machine over a period. However the machine start time varies from 10:00 pm to past midnight. I have tried reviewing past posts but cannot seem to find a similar query.

I need also to calculate difference between dates(dd-mm-aaaa hh:mm) in workhours ( hh:mm):

The work period is 9-18 with lunch interval 13-14 The startdate and end date could be out of the work hours and i can't include the extra hours. I can have several days (workdays) at the difference, but i should maintain the format hh:mm.

Ex1: Startdate 05-03-2013 18:34 ( date to calculation should be 05-03-2013 18:00) end date 06-03-2013 10:30 Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 ) will be equal to: Startdate 06-03-2013 8:34 ( date to calculation sould be 06-03-2013 9:00 ) end date 06-03-2013 10:30 Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

Ex2: Startdate 06-03-2013 12:01 End date 06-03-2013 14:28 Time Difference 01:29

Column A is the COB Date Column B through N are various stock data. I would like to calculate the trend of correlations over a 4 year period. I can't seem to figure out how to manipulate the data analysis tool pak to do this.

I need to determine a formula which will allow me to calculate a future date based upon a current date with varying time periods.

For example:

I have a bill which is paid on the 15th and last business day of each month. I would like to be able to see the next due date regardless of what day of the week it is.

I have a bill which is paid every other Tuesday. I would like to know the next due date without having to enter +14 for every due date in the future. In other words, it is preferable to be able to open the spreadsheet and automatically see the next due date, not use autofill to repeatedly add +14 to a previous date which would limit the # of future due dates that could be calculated.

I have a bill which is paid on the last business day of each month, not the last Friday of each month. I would need excel to return a value for the last day of the month which = Monday-Friday, regardless of what day of the week it may be as long as it isn't Saturday or Sunday(holiday exclusion would be nice but not required).

im trying to put together a system on worksheets that checks 'Absence' in a rolling 12 month period. The 12 month period is any 12 months and not a financial period (eg 25/12/06 -25/12/07).

I have 36 employees and want to have their names in each sheet, calander dates across the top, will mark either a 'S' for sick or 'L' for late ect against the dates if not at work.

Once an absence has been entered, on the sheet somewhere it will show how many days that person has been off (eg, 10th Oct, 16 Nov and 22 Dec would = 3 Days absence).

How do I set up the sheets to work out how many days each person has had off in a rolling 12 month period (so that it does not calculate beyond the 12 months).

I have looked on here to see if there are any programs, formulas which may work but some have lost me in my tracks.

I am trying to re-jig a formula that shows hours worked for a particular day, to showing any absence detail shown for a particular employee. I have the fllowing formula which doesn't work and I'm not sure why. A similiar formula works for me getting basic hours worked etc

My range names are correct and all have the same 'length'. F67 is 09/05/05; StaffNumber = 100 and the value that is within the AbsenceDetail cell for the 09/05/05 for # 100 is Holiay, except my formula returns 0 (I have it formatted as General)

I am trying to get the correct formula to count the number of days it has been for each employee since the last occurrence of an absence/tardy. For each employee, starting with the beginning of the year, we mark and employee as Absent as an "A" or Tardy as "T". See below the examples.

Captain America ................................A ..........................T .....................................T Incredible Hulk.......................................................................................... A Spider Man ........................................................................................................................ ........A Iron Man ....................................................T

( I added dots because it wouldn't let me space them out?)

We are keeping track so that employees have the ability to make up numbers because after so many occurrences they can become terminated. If an employee has about 60 days in a row without an infraction, that employee can deduct a day from their total on the year.

Any formula to use. Also to include a vlookup so that I could have their name as well with the number of days on a separate tab!

i need to share the valve of the job over the months. see attahed excel sheet. say the job worth 10k has a start date of the 30th of nov and the end date is the 1st of dec. the value of the job is shared between two days and then put into the relevent cell. as regards to the months they are not calander months so the start date and end date of the months are diffrent see attached sheet for full details.

I need to find out last occurrence of price (Last Date of Occurrence). Column A contains Date; Column B contains Highest Price of Equity Stock in that date. Reference price (Price we want to look up) is calculated in Cell E1, Cell E2 contains start of evaluation period (date), Cell E3 contains end of evaluation period (date). I want to find out the date on which "last" occurrence of Reference price in Column B "during the evaluation period" was found.

I have a work book that has about 1200 entries. I'd like to grab everything that comes after the last comma or the last period in the cell. Can this be done?

I have a sheet i am working on at the moment, i basically have in Column A (named Interview Date) a date and in column Q (named Date Cleared) another date.

What i want is so when i enter a date in column Q if the date is 14 days or more after the date in column A it will highlight Blue and if the date is upto 14 days after the date in Column A it will highlght green.

How can I find the total of interest (or and expense) during a given calendar range

Data is as follows

Date Type Amount 4/1/11 Interest 4.00 4/15/11 charge 22.00 5/1/11 interest 3.00

I want a cell to compute the interest in april only.

I have tried =sumif(range, end date, amount_range)- sumif(range, beg date, amount_range)

but how do I nest the type argument into the argument

Possible approaches advanced filter? and function? add another column that uses an if statement to do interest only and do the sumif statement above I was hoping to have a drop down box that could have interest, COGS, beside it and april, may, june above it

I'm trying to do a very simple web query drawing a table of holidays based on what country you select.

I'm using this very basic parameter setting

WEB 1 http://["Web Address"] Selection=EntirePage Formatting=All

[Code]....

I set up the connection and when I add the country (using a separate cell and a concatenate) the URL looks ok in the cell (www.timeanddate.com/holidays/Ireland) but the query returns an error saying it it's unable to open "www.timeanddate.com/holidays/Ireland."

I'm attempting to chart 3 series over a 24 hour period (8am-8am). The 3 series are captured in 1 minute intervals. My X axis intervals is displayed hourly though. My issue is, charting goes bad at 00:00:00. i.e. it stops.

I'm doing research with a professor at the University of Florida. This is my first time using Excel to any extent, so I need everything from the ground up!

I have the housing values for each of the 50 states from 1975 to 2006. I need to analyze each state individually to see if there were any points during that 26 year span when housing values increased by more than 20%. I need to know when this increase started and when values peaked and began to fall. I could do this manually, but I'm assuming that would take a while.

Is there a simple way to do this in excel? A macro, or a UDF (I have no clue about either of them by the way).

The 50 states are listed in a column and the rows next to each state having housing values for the 26 years. ( I don't know if that is relevant).

Replaced the period with a colon, 8.23 resulted in 8:23. I have since deleted the Add In. Now every time I enter a "." it is replaced by a ":". This happens even when I disable macros on the spreadsheet. I cannot see any VBA code.

I have an Access DB that I query with excel and I pull two years worth of sales data. I have tried using a pivot table report to display the following data, but I can't figure out how to display the data in the following format.

The pivot table will give period and YTD but the totals for YTD are not cumulative for the year up to that period (it seems to total the period only).

For the current Year- period (month) and YTD (only up to the period displayed).

For the last year- period and YTD (only up to the period displayed).

The fields I query are Customer, City, Product, Salesperson, Period(month), Year and Sales

I have tried putting the queried data on one sheet and then using formulas on another but I am not having any luck.

I would also like to be able to select which period I am viewing but this is secondary.

c: estworking filesabc123.xls c: estworking filesabc123xyz.xls and so on....

How to write the function to extract the string of text after the last backslash () and before the period (.) (i.e. "123 & xyz in the above example"). The length of the path is inconsistent in the column; still the function should extract it.

I'm trying to total data only up to the current period so I presume the answer lies in a =sum and index but I can't get it to work. The attached worksheet explains it better.
