formula to calculate number of hours worked in a day

[xololady]

I am trying to put together a time sheet, where I can put my time in and out,
and then give the total hours at the end of the day. For example, I sum (12
pm -8 am) + (5 pm -1 pm). I have formatted these cells to show time. But my
formula spits out a sub zero number. Do I need to divide these by 24?

Format cells as hh:mm and Total cell as [h]:mm: the latter will stop Excel
subtracting 24 from the total if it is >24

Start time in A1 and Finish Time in B1

in C1: =MOD(B1-A1,1)

This will allow for times running over midnight

If this doesn't ever happen then =(B1-A1) will suffice

Assuming times are in rows 1 to 7 , then in C8: =SUM(C1:C7)

C8 formatted as [h]:mm

Thank you! That worked! I thought my formula made sense, but it didn't
work.

If you want to get decimal hours, rather than Excel time format, divide by
24 and format as General or Number.

But the answer is 8 hours, not a sub-zero number. You may need to check
that all your data are times, not text. Temporarily format the four input
cells as number, rather than time, and then you should see them all change
to decimals of a day. If they don't all change to decimals of a day, there
may be spare spaces or non-printing characters which are keeping them as
text.

OK< Next question. When I total the hours at the bottom, I want to take that
total and multiply by an hourly wage, such as $8. I got 10 hours for a sum,
but when I multiplied it by 8, I got $3.33.

I got the hours to do what I want. Now I am trying to calculate wages
earned. So I add the total hours by $8. I got 10 hours times $8 and it gave
me $3.33. The hours are formated as time and the total hours is formated as
time. I calculated the pay cell cell as currency.

If you want to convert Excel times (which are counted in days) into hours,
then you need to multiply by 24. Your 10 hours, if still an Excel time, is
stored as 10/24, so when you multiply by 8 you get 3.33.

[Toppers]

If total hours in C8 (as per my posting), then in D8:

=C8*24*8 and format as NUMBER (or Currency)

If you want total hours to be decimal number:

in C8: =SUM(C1:C7)*24 and format as NUMBER

in D8: =C8*8


(As per David's replies)

I was, of course, asleep when I said DIVIDE by 24. I should have said
MULTIPLY by 24.
