How to improve your margin
- Raise prices on jobs where you hold the most value and the least competition
- Negotiate materials costs or switch to a supplier with a volume discount
- Reduce drive time per stop by grouping jobs by neighborhood or day
- Add recurring service agreements to smooth revenue and lower acquisition cost per dollar billed
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
