Enter the total cost of the plumbing job and the total number of hours spent on the job to determine the plumber cost per hour.

Plumber Cost Per Hour Formula

The following equation is used to calculate the Plumber Cost Per Hour.


  • Where PCH is the plumber cost per hour ($/hour)
  • TC is the total cost of the job ($)
  • TH is the total number of hours spent working on the job (hours)

To calculate the plumber cost per hour, simply divide the total cost of the job by the amount of hours spent on the job.

What the cost of a plumber per hour?

The national average for a licensed plumber is about $70 – $85 per hour, but a master plumber or a plumbing contractor can charge up to $120 per hour if the job is complex. And, this doesn’t include what you’ll pay for parts and materials.

If you need a simple repair like replacing a faucet or toilet, you can expect to pay less than $125 for labor and parts. However, more complicated plumbing jobs like installing new pipes can cost several hundred dollars or more in labor alone.

Rates vary depending on the type of work requested, license, and experience level.

The cost to hire a plumber could go up if you need emergency service or if the project involves some specialty work like gas line repair or installation.
