1099 Field Kit asks whether Saturday’s job paid for itself

Field notes

The calculator models a job from the driveway outward: quoted price, owner and helper time, round-trip business miles, materials, disposal, and payment fees. It distinguishes cash leaving the business from economic owner labor, then calculates contribution margin and effective hourly earnings. The page uses a pre-filled gutter-job example, including $16.72 in mileage and $180 in owner labor. A separate Excel workbook is listed at $97, but checkout is not live; a $49-per-month Books version is presented as a waitlisted product.
