Timesheet - What time to clock out not to exceed 37.50 hours?

An image attachment has limited value. Just attach the Excel file. It's easier than taking a screenshot first and then attaching that. Having your file allows us to see and experiment with your data, layout, formulas, code, and possibly attach a file with a completed solution. If you are looking for formulas to produce a desired result, it helps if you create a mock-up of what you want the result to look like. Otherwise we would have to build something from scratch, trying to guess what you want it to look like.

The paper clip icon does not work for attachments. To attach a file:

1. Under the text box where you type your reply click the Go Advanced button.
2. On the next screen scroll down and under the Attachments section click the Manage Attachments link, which will show a pop-up window.
3. Click the Choose File button to select a file to attached.
4. Click the Upload button to upload the file.
5. Then click the Close This Window button. Your file is now attached to your post.

I am sorry, I thought I attached the actual file.

Case:

Clock in each day (Monday - Friday)
Clock out for lunch each day (Monday - Friday)
Clock in after lunch each day (Monday - Friday)
Clock out end of day each day (Monday - Friday)
Calculate total hours worked (cumulatively)

Each day the work hours are 8:30 - 5:00 p.m.
1 hour break for lunch.
7.50 hours each day.
37.50 hours each week.
Anything over 37.50 is considered overtime.

the system will review the hours worked and determine what time the employee needs to clock out to avoid going over the 37.50 hours\

That is what I'm hoping to achieve.

Try

in H15

=D11+($H$2-SUM($F7:$F10)-($C11-$B11))
