- Loaded Plumber Rate: Base hourly wage plus payroll taxes, workers comp, health insurance, and paid time off.

Frequently Asked Questions
What is a plumbing service call fee?
A plumbing service call fee (or diagnostic fee) covers the business expense of dispatching a equipped plumbing van to a job site, inspecting pipes, fixtures, or drains, testing pressure, and diagnosing leak issues before repair work starts.
How do I calculate a profitable diagnostic call fee?
Sum loaded plumber labor cost (base wage + payroll taxes & benefits), vehicle fuel and wear allocation, and dispatch administrative overhead for the diagnostic visit. Divide total direct costs by (1 - target gross margin) to establish your target call fee.
Should the diagnostic call fee be credited toward repair work?
Many plumbing contractors waive or credit the initial call fee toward the repair subtotal if the customer authorizes the repair proposal on the spot. Others charge it separately to cover non-billable drive time.
