Plumbing Maintenance Revenue Calculator
Project revenue from maintenance visits and the work those visits surface.
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.

- Visit volume and what each visit is priced at.
- Work found during visits, which is usually larger than the visit fee.
- Travel, which on short maintenance visits dominates the cost.
Where this one goes wrong
Modelling the visit fee alone. Maintenance rarely pays on the fee; it pays on the work found and on keeping the customer, and a model that ignores that concludes maintenance is not worth doing.
Questions
About this calculator
Is plumbing maintenance worth selling?
It is worth it for the work it finds and the customer retention it produces, provided the visits are routed sensibly. Priced as a standalone service with poor routing it rarely pays.
What should a maintenance visit include?
A documented inspection with findings, not just a task list. The findings are the value and the reason the customer renews.
How should visits be scheduled?
Geographically clustered and spread across quiet weeks. That turns a marginal visit into a viable day and fills capacity that would otherwise be idle.
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.
