Why plumbing contractors track profit margin on every job
Revenue is not profit. A $850 plumbing service call can net $45 or $280 depending on loaded labor, parts cost, drive time, commission, and overhead recovery. Most shops discover they are underpricing install and over-discounting service because they track revenue, not margin per job.
Industry-standard pricing uses burdened labor (not base wage), materials at wholesale cost, overhead recovery per billable hour or job, and the divisor method for target net margin, not simple markup. This calculator implements both single-job and monthly business views with plumbing-specific gross and net margin benchmarks so you can validate flat-rate prices before they hit your P&L.

Profit Margin Calculator FAQs
Plumbing service work typically needs 55-65% gross margin and 15-25% net after overhead. Install and project work runs lower gross (38-55%) but higher ticket volume. Your market, crew efficiency, and overhead load shift these ranges, use benchmarks as a starting point, not a ceiling.
Gross margin is (revenue − direct job costs) ÷ revenue, labor, materials, subs, and commission on that job. Net margin subtracts business overhead (rent, office, marketing, non-field payroll) and reflects true shop profitability. A job can look profitable on gross margin and still lose money if overhead is not recovered.
Base wage ignores payroll taxes, workers’ compensation, benefits, and non-billable time. Burdened rate is the true hourly cost of putting a tech on a job, typically 25-35% above base pay. Pricing from base wage is the most common reason contractors underprice service calls.
