The Job Cost Grid displays and calculates your bid numbers.

    The divisor column divides all your totals, what you enter in this column is 
  very important !

  The Job cost Grid is the main focal point of the RoofCalculator program. It collects all the numbers
 you have entered and divides them into the usable units you have specified. It totals your squares and calculates your total price based on the price per square you enter.

 The yellow shaded cells in the units column is where you will always enter your price per square.

The top row is a total of your roof area measurements with pitch added + 5% for waste.
The 4085.75 is the total of your actual roof measurements.
The Sub-Total is 4085.75 x 1.08 = 4412.61, = pitch has been added.
The waste is 4412.61 / .95 (Divisor) = 4644.85. If you do not want to add for waste then enter 100 as the divisor.

You can see the details of all your calculations by looking at your form or your form
