How this calculation works
Margin = (revenue − cost) ÷ revenue. Most owners only count materials when they think about job cost, but labor is usually the biggest line. A $850 job with $280 labor + $175 materials + $35 fuel + $25 other = $515 total cost = $335 profit = 39% margin. Looks healthy. But if labor is actually $400 (because the tech took longer than estimated, or you forgot payroll tax loading), margin drops to 25% fast. The "recommended price increase" line shows what you'd need to charge to hit a 30% margin if you're below it. Industry healthy benchmark for field service is 25-35% gross margin per job. Anything below 20% means you're working too hard for too little.

HVAC owner reviewing last month
$850 invoice, $280 labor, $175 parts, $35 fuel, $25 other.
39% margin: healthy. But if labor was actually 1.5 hr longer than estimated, margin drops to 25%. Tighter time tracking is where the leverage is.
Cleaning company audit
$385 deep clean, mostly labor.
Labor-heavy services have thinner margins by nature. The recommended price increase shows what to charge to get to 30% target.
Project with subcontractor
$2,400 project, $850 subcontracted out.
Subs eat margin fast if you don't mark them up. Best practice: 15-25% markup on sub costs, treated as a parts pass-through.
