Plumbing Business Revenue Calculator
Project revenue from capacity, average ticket and the mix between service and installation.
Result
Service lines rarely carry the same margin. Splitting them is the only way to see which part of the business is paying for the rest, which is frequently not the part that looks busiest.

- Plumber hours available, which is the hard ceiling.
- Average ticket by work type.
- Close rate on quoted work.
Where this one goes wrong
Planning revenue growth without planning capacity. Revenue targets that exceed available plumber hours are a plan to disappoint customers rather than a plan to grow.
Questions
About this calculator
What caps plumbing revenue?
Billable plumber hours, until more are added. Every growth plan meets that ceiling eventually, so it is worth modelling rather than discovering.
How do I grow without hiring?
Raise the share of hours that are sold: less travel, fewer return trips, better close rate. Those add capacity from the hours already paid for.
Is contract work worth pursuing?
It smooths demand and typically pays more slowly at lower margin. Whether it suits depends on your cash position more than on your capacity.
The formula
revenue = jobs x average value; gross profit = revenue x margin

How sensitive the answer is
Holding everything else steady and changing only average value, this is what happens to repair revenue per month. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Average value ($) | Repair revenue per month |
|---|---|
| $240 | $6,720 |
| $360 | $10,080 |
| $480 example above | $13,440 |
| $720 | $20,160 |
| $960 | $26,880 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.

Before you rely on this number
Pipe sizing, flow and pressure figures depend on the actual fittings, the run, the material and local code. Code requirements vary by jurisdiction and override any general calculation, so check what applies where the work is happening.
