Result

Net profit -$2,200
Net margin -5.6%
Total direct cost $29,200
Profit per working day -$100
That is -$2,200 at a -5.6% margin, about -$100 for every working day.

Net profit here is before tax and before any owner's draw that is not already inside overhead. If you pay yourself out of what is left, this figure is your wage rather than the company's profit.

What moves the number

  • Overhead, which continues whether the vans roll or not.
  • Owner compensation, treated as a cost rather than as whatever remains.
  • Bad debt, which in plumbing is real and rarely budgeted.

Where this one goes wrong

Treating owner pay as profit. If the owner is doing work that would otherwise be hired for, the market rate for that work is an expense and profit is what remains after it.

Questions

About this calculator

Should the owner take a wage before profit?

Yes, at a market rate for the work actually done. Otherwise the business looks profitable while the owner is unpaid, or the reverse.

Where does bad debt belong?

As a cost, budgeted from experience rather than discovered. Every service business writes some off and pretending otherwise flatters the figure.

What net margin is normal?

It varies with mix, size and market, so your own trend is more useful than a benchmark whose definitions you cannot see.

How useful was this calculator?

Not rated yet. Yours would be the first.

The formula

A worked example

These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.

What goes in

What comes out

ResultValue
Net profit main result-$2,200

Profit per working day-$100

That is -$2,200 at a -5.6% margin, about -$100 for every working day.

How sensitive the answer is

Holding everything else steady and changing only revenue, this is what happens to net profit. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.

Revenue ($)Net profit
$19,500 -$21,700
$29,250 -$11,950
$39,000 example above -$2,200
$58,500 $17,300
$78,000 $36,800

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.

Estimating is the easy part

The jobs you never hear about cost more than the ones you mis-measure. BDEVY builds the marketing, systems and automation that bring them in.
