Calculate Overtime double time

[shizuka]

Hi...
I am having a hard time calculating over and double time.
I am making a list and i have this columns:

Start time Finish Time Reg time Overtime Double time Total hrs
8 AM 7.30 PM

To calculate the regular time I have used this formula:
=IF(((H9-G9)*24)>8,8,(H9-G9)*24)

To Overtime
=IF((H9-G9)*24>8,(H9-G9)*24-8,0)

To total Hrs
=IF((OR(H9="",G9="")),0,IF((H9<G9),((H9-G9)*24)+24,(H9-G9)*24))

And I am having trouble doing the Double time...
And I think the 3 formulas I have used aren't correct, because Regular time
cannot be more than 8h, and overtime can not be more than 4hrs... the rest
goes to double time...
Can you please help me???

Hi,

Let's deal with the regular time first - here is a shorter formula:

=MIN(24*(H9-G9),8)

Overtime:

=MIN(MAX((H9-G9)*24-8,0),4)

Double time:

=MAX(24*(H9-G9)-12,0)

Total:

=SUM(Regular,OT,DoubleTime)

Where Regular,OT,DoubleTime just represent the cells containing the above
three formulas.
