How to Calculate Profit Margins for Contractor Jobs
Many contractors underprice jobs by forgetting overhead costs or using incorrect markup formulas. This calculator uses the industry-standard formula to ensure you hit your target profit margin every time.
The Formula
Selling Price = Total Cost ÷ (1 - Target Margin %)
Example Calculation
- Labor: $95/hour × 2 hours = $190
- Materials: $150 (HVAC filter, refrigerant)
- Overhead: $30 (vehicle, insurance, tools)
- Total Cost: $370
- Target Margin: 30%
- Selling Price: $370 ÷ (1 - 0.30) = $528.57
- Your Profit: $528.57 - $370 = $158.57 (30% margin)
Common Mistakes to Avoid
- ❌ Using Markup Instead of Margin: 30% markup ≠ 30% margin. Markup adds percentage to cost (incorrect for margin goals).
- ❌ Forgetting Overhead: Vehicle costs, tools, insurance, and unbillable time must be included in every job.
- ❌ Lowering Margin for Competition: If competitors charge less, they may be undercharging or less experienced. Maintain profitable margins.

|---|---|
| HVAC | 25-35% |
| Plumbing | 30-40% |
| Electrical | 30-40% |
| Roofing | 20-30% |
| Landscaping | 35-45% |
