Spyder:
You have to take all your expenses that are not directly related to jobs, come up with a total dollar amount first. (Office/Insurance/Vehicle Costs/etc)
Then, take the above total & divide it to get a "per day cost"
Take the projected days for the bid job & multiply by the daily cost and thats overhead recovery.
Don't overlook Health Insurance , Tax expenses related to payroll & Workers Comp, unless you figured these costs into your "Labor" figures.
