How the plumber break-even rate works
Your break-even rate = (target salary + all annual overhead) ÷ real billable hours per year. Your target rate adds your profit margin on top. If your target rate is above what you currently charge, every hour you bill below it is subsidizing your customers.
Frequently asked questions
How do I calculate my plumbing hourly rate?
Add your target salary and all annual overhead (truck, insurance, tools, rent, software), divide by your real billable hours per year. That number is your floor — profit margin goes on top.
How many billable hours does a plumber have per week?
Typically 20–28 of a 40-hour week once you subtract drive time, parts runs, and quoting.
What profit margin should a plumbing business target?
Residential service plumbing should net 10–15%. If you're below that, raise prices before cutting costs.
Is flat-rate pricing better for plumbers?
Yes — a flat-rate price book built from your true hourly cost protects you from slow jobs and makes quoting instant.
