Multiplying the results of two columns of sums - Total Billed and Total Paid

I'm sure there's a simple answer to this, however I'm new to Excel and can't seem to find a suitable answer by Googling this issue. Thanks in advance for your patience, I'll try to explain the issue the best I can.

Here's the background:

I have a number of contract employees that work variable hours, I pay them a specific rate and bill my client for their services, at a marked up rate. I'm trying to calculate the TOTAL I pay the contractors over a two week period; and the TOTAL I bill the client over a two week period.

I've attached a sample worksheet, however in case there's issues opening it, my spread sheet looks like this:


Pay Rate Bill Rate Pay Period 1 Pay Period 2 Profit

Employee A $20.00 $25.00 40 40 $400.00
Employee B $30.00 $35.00 35 40 $375.00
Employee C $20.00 $25.00 40 40 $400.00
Employee D $15.00 $20.00 45 40 $425.00
Employee E $30.00 $40.00 40 40 $800.00
Employee F $25.00 $35.00 40 40 $800.00
Employee G $30.00 $45.00 40 40 $1,200.00
Employee H $40.00 $50.00 40 40 $800.00



Total Pay ??? (need formula)

Total Billed ??? (need formula)

The formula I use to calculate the "Profit" per line is =SUM((C2-B2)*(D2+E2)) (e.g. Profit for "Employee A")

What I need is a formula that allows for the variance in weekly hours, and automatically calculates the 'Total Pay' and 'Total Billed' fields.

Any help would be greatly appreciated!!
