About this tool

What the Plumbing Job Pricing Calculator does

Flat-rate pricing quotes a fixed price per task instead of charging by the hour. The price is built from the expected labour time at a billable rate that covers wages, vehicles and overhead, plus parts with a markup and a trip or dispatch charge. Knowing the cost behind it shows the margin you keep.

It also works as a plumbing job flat rate pricing calculator or a flat rate pricing calculator.

Formula

  • Price = hours × billable rate + parts × (1 + markup) + trip charge
  • Direct cost = hours × technician cost + parts
  • Gross margin = (price − direct cost) ÷ price

Worked example

Using the starting values in the calculator above:

Input Value
Expected labour hours 2.5
Billable labour rate $125
Parts at cost $85.00
Parts markup 50%
Trip or dispatch charge $75.00
Technician cost per hour (wage and burden) $55.00
Result Value
Flat-rate price $515
Gross margin 56.8%
Gross profit $293
Direct cost (labour and parts) $223

How to read the result

Gross margin must also cover unbilled time, vehicles, marketing and office costs, which is why service businesses often target 50% or more.

Base the hours on your average for the task, including diagnosis and clean-up, not your best day.

For planning only. Electrical, gas and refrigerant work must follow current codes and be carried out or checked by a licensed professional.
