Margin is applied divide-style (price = cost ÷ (1 − margin)), so the margin you set is the margin you actually keep — the #1 flat-rate mistake is multiplying by (1 + margin) and keeping less than you think.
How this calculator works — the formula
materials = (parts + PVC lengths × metro price) × (1 + misc%)
price = (materials + hours × burdened rate) × (1 + overhead%) ÷ (1 − margin%)
The misc percentage covers fittings, primer/cement, hangers, and tape — the small stuff that eats margin when nobody itemizes it. 8–12% of materials is typical for service plumbing.

Questions contractors actually ask
How do plumbers price flat-rate jobs?
Task by task: parts at cost, labor at the burdened hourly cost times the book time, overhead recovery on top, then margin applied divide-style. That price goes in the book and gets quoted before work starts — this calculator is that math for one task.
What does PVC pipe cost right now?
As of Aug 24, 2026, PVC Sch-40 1" × 10 ft runs a national median of $7.65 at big-box retailers, with metro prices in the table on this page. Re-verified weekly — the stamp moves only when a fresh check succeeds.
What margin do plumbing service calls target?
Commonly 15–25% net after true overhead recovery. Drain/rooter work often runs higher margin on lower materials; repipes flip that. The engine above keeps the target honest either way.
