The standard plumbing flat rate pricing formula is:
Flat Rate Price = (Labor Rate × Labor Hours) + Parts Cost + Overhead + Profit Margin
Each variable includes hidden costs many plumbers underestimate:
- Truck and stock costs — fuel, insurance, maintenance, and the parts you carry on the truck. This often adds $10–$25/hour to your true cost of deploying a plumber.
- Loaded labor — beyond the hourly wage, factor in payroll taxes, workers' comp, licensing, training time, and PTO. The real cost of a $30/hour plumber is usually $42–$55/hour.
- Callback allowance — build 3–5% into your flat rates. Sewer and drain work in particular has a higher callback rate than most trades.
- Emergency/after-hours pricing — nights, weekends, and holiday calls should carry a 1.5×–2× multiplier to cover on-call pay and the opportunity cost of pulling a tech from scheduled work.
Most profitable plumbing shops target a 50–60% gross margin on flat-rate repair work. If your margin is below 45%, your loaded labor rate or parts markup is likely too low.
Flat Rate vs Hourly Pricing
| Flat Rate Pricing | Hourly Pricing |
|---|---|
| Predictable invoices — customer knows the price before work begins | Variable billing — final cost unknown until job ends |
| Faster approvals — techs present price from the book instantly | Slower approvals — customers hesitate when cost is open-ended |
| Consistent margin regardless of how fast the tech works | Fast techs get penalized; slow techs get subsidized |
| Fewer invoice disputes — no surprises on the bill | Higher dispute rate — customers question hours logged |
How to Use This Template
Download the PDF and use it as your technicians' field reference. Print it, laminate it, or load it onto a tablet so pricing stays consistent between the office and the truck.
Customize in this order: first update your loaded labor rate, then adjust parts costs for your suppliers, then set your target margin, and finally revise line items so the mix matches the jobs you actually run — drop what you never do, add your top callback repairs.
