Working hours calculation (with Neg time) in Excel

This is a mathematical notation for a function of a variable x.
Let there be two quantities say the number of hours worked per week (x) and the salary you get paid (y).
The number of hours you work is the independant variable. The salary paid is the dependant variable.
For each amount of hours you work, your boss calculates the salary that is owed you at the end of the week. The method your boss uses to calculate your salaray is the function.
Symbolically, this can be represented as
Salary ($)=f(hours vorked) or
y=f(x)

For example: if the hourly rate is 8$/h and you work 35h then what is owed you is
35h*8$/h=280$
If you work more hours you will get more pay and if less hours, less pay
The rule is y=8*x

Hi,
Thanks for using fixya , but could you be more specific , with the application or the software you are trying to use these functions in ,
eg, Microsoft excel or normal windows calculator .


Thanks

You can access the .pdf manual for your particular calculator here:

Page 1 for how to set date/time:

“RATE SET”: To set the date, time, and tax rate, set this switch at the “RATE SET” position.
Date:
• Enter in the order of month, day and year, then press to complete the entry.
• Use to separate month, day, and year.
• When is pressed, the number entered is evaluated and displayed as “date” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
date is restored.
Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits)
Time:
• Enter in the order of hour, minutes, then press to complete the entry.
(There is no entry available for the seconds value. The clock starts at zero second.)
• If the hour/minute digit is less than 10, it is not necessary to enter the first digit “0”.
• Use to separate hour and minute values.
• When is pressed, the number entered is evaluated and displayed as “time” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
time is restored.
Hour: 0 - 23 (24-hour system for the hour entry), Minute: 0 - 59

Format both cells with the time format "h:mm AM/PM".
Lets say the start time is in cell A2 and the stop time is in cell B2. In cell C2 put the formula =B2-A2 and custom format the cell C2 as: "h:mm"

Its the same only the interface is different. Use the same technique of the Mathematical algorithm keeping in mind the way the date, time are displayed in their format. Also switch to 24 Hr mode....sodeep

use the below formula to get the date of the LWD (Monday thru Friday) of the month.
Assumed that if the date in cell A1 is 6-May-2005. then formula will be
=DATE(YEAR(A1),MONTH(A1)+1,0)-(MAX(0,WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,0),2)-5))

Excel is a spreadsheet - it is less structured than a database and all of the data appears on one (or more) pages along with many calculations and summaries of data.
A database is structured so that all the information is kept in the same format for each member record of the database - Databases are better at processing larger volumes of information.
Some tasks can be performed equally well in either spreadsheet or database -
Often data is stored in a database but analysis is done in the spreadsheet.

Hello,
The formula should go like this:
=IF(C11>40,(C11-40)*D11,0)
This one will give you the result of (ONLY overtime hours)*(hourly wage), and if there are no overtime hours the result is 0.
Now, if you need to multiply that result with say 1,5 or whatever - insert the number you need like this:
=IF(C11>40,(C11-40)*D11*1.5,0)

If you need more help, please ask.

Just enter using this style


TIME IN TIME OUT HOURS 10:00 16:50 6:50 10:22 17:34 7:12 9:00 10:00 1:00
the formula in HOURS is Time Out - Time In

When i first figured out how to pull data from SQL and put the results in an excel file i referenced these two articles....
Reading and writing excel file using VB.NET (http://www.codeproject.com/KB/vb/Work_with_Excel__VBNET_.aspx)
Get the Values From DataBase and Stored into excell Sheet (http://www.codeproject.com/KB/vb/Getvaluesfromdatabase.aspx)

This is the code i ended up using.... (check out those links to see how you need to import the ms office excel reference file with visual basic)
