Plumbing margin is easy to overstate when the estimate only includes parts and the time spent at the fixture. Travel, dispatch, warranty callbacks, truck stock, fuel, licensing, insurance, and non-billable technician time all affect whether a job really contributes profit.
Use this calculator to review a job, a service line, or a month of plumbing revenue. The goal is not only to see a percentage, but to decide whether pricing, scheduling, or callback control needs attention.
Use revenue from the job or period, subtract direct parts and subcontractor cost for gross profit, then subtract payroll, truck cost, insurance, rent, software, marketing, and admin overhead for net margin.
A plumbing company records $85,000 in monthly revenue, $24,000 in parts and subcontractor cost, and $43,000 in payroll, fuel, truck, insurance, rent, software, and admin overhead.
The margin may be acceptable if callback rates are low and technicians are well utilized. If net margin is weak, look at dispatch density, billable hours, and whether flat-rate pricing covers truck overhead.
For job-level margin, technician labor usually belongs in direct cost. For this calculator, include it consistently either in cost of goods sold or operating expenses and compare periods the same way.
Track callback labor and parts as real cost. High callback rates can make an apparently profitable job type unattractive.
Yes, if you enter job revenue and job-specific cost. Monthly overhead still needs to be allocated separately for a full net margin view.
Turn plumbing scope, parts, and payment terms into a clearer invoice.
Use the broader construction model for project-based work.
Estimate loaded labor cost for field crews.
Focuses on food cost, labor scheduling, delivery platform fees, waste, rent, and the difference between menu-level and month-level margin.
Connects margin to occupancy, average daily rate, OTA commission, housekeeping load, utilities, amenities, and event or food revenue mix.
