some of the not so good responses here. First of all - forget about percentages. Jobs should be based on actual estimated material costs. The material costs should also factor in waste, fudge factors, etc. You also need to calculate your production hrs. Production hrs need to include loading and unloading, clean up, drive time to and fro per employee. You also need to factor in your labor burden. No one here can tell you what your labor burden is, that is data that only you know and must calculate. Where will you go wee-wee? Did you factor in a Porta Potty rental or will you jus pee behind the customer's house and make it smell to high heaven? Profit? The profit margins in the hardscape industry are not very good. The NATIONAL ANNUAL average is around 8%, according to a VanderKoi seminar I attended. For us, I shoot for 20-25% net profit on a per job basis.
