What a profit margin calculation should include

Most service business owners know their revenue and have a rough sense of what labor costs, but margin slips away in the categories that stay invisible until the bank account runs low.

Total revenue — all income from completed jobs and contracts in the measurement period, including service, parts, and any add-on fees
Cost of labor — wages, payroll taxes, workers comp, and benefits for field techs, since labor is usually the largest line
Cost of materials and supplies — parts and consumables that go directly into jobs, tracked separately from overhead
Vehicle and equipment costs — fuel, maintenance, lease payments, insurance, and depreciation on trucks and tools
Overhead expenses — office rent, software subscriptions, advertising, licensing, insurance, and owner salary
Target net profit — the dollar amount or percentage the owner wants to retain after all costs, which is what the calculator solves against the inputs
One-time vs recurring split — what share of revenue is recurring service agreements versus one-time jobs, since the mix affects the long-term health of the margin
Owner compensation policy — whether the owner takes a market-rate salary or draws on profit, since that decision changes what "net margin" actually means for the business

Track real margins automatically with Claver

Claver pulls actual job costs from the field, so margins are tracked per job automatically rather than estimated from monthly aggregates. The owner sees which technicians are hitting target margins, which jobs are running over budget, and which service lines are quietly eroding profitability. Over time the system surfaces patterns in underbid work so pricing corrections happen before a slow month lands on the books.

Profit margin calculator — FAQ

What is a good profit margin for a service business?

Most profitable service businesses target a net margin between 15 and 25 percent, though the right number depends on the trade, region, business model, and how much the owner pays themselves on top of operating profit.

Can Claver track margins on every job?

Yes, Claver tracks job costs against the quoted price on every work order, so margins are visible in real time without manual calculations or end-of-month reconciliation in a spreadsheet.
