Timesheet formula for calculating ordinary hours and overtime hours.

Hi I am building a timesheet and I have become a bit stuck.

I have already got the timesheet to automatically calculate the number of hours once the start time and end time are entered(these cells are all in hh:mm format). The column which calculates the total time is AA4.

Then I have the following columns:
Wages rate: Y4
Ordinary total: AB4
Overtime total:AD4
(See attachment)

After 38 hours we need to pay at the overtime rate, so I can't just multiply the total hours by their hourly rate.

I need two formulas that will

1. Work out ordinary hours: If the number of hours is less than or equal to 38 it will calculate the hours (up to 38) by the rate, but if it is greater than 38 it will just multiply the rate by 38 (giving maximum number of ordinary hours)

2. Work out overtime hours: Where the hours exceed 38, I need a formula that will calculate how many hours are greater than 38 and multiple these additional hours by the rate by time and a half.

Can someone help me I have been stuck on this for two weeks!

Cheers

Thank you so much JBeaucaire!

I just have one further problem, column AA doesn't seem to be working properly. I have tried a sum formula to total the hours from each day to the weekly total but it seems to stop at 13:30.

Should I be using the time format, is that what is preventing this column from working?. If I switch to number format it gives me an incredibly low number (like 2.5) when I put in dummie times that total to 60+ hours.

Once again, thank you so much- I am learning slowly!!

Thank you, you beauty!

I hope you have a lovely Christmas!
