Practical Example
Let’s say you’re a contractor working on a $50,000 project.
- Contract Value: $50,000
- Cost of Goods/Services: $20,000
- Additional Costs: $5,000
- Overhead Percentage: 10%
Now, let’s calculate:
- Overhead Costs: $50,000 × 10% = $5,000
- Total Costs: $20,000 + $5,000 + $5,000 = $30,000
- Gross Margin: $50,000 – $30,000 = $20,000
- Margin Percentage: ($20,000 ÷ $50,000) × 100 = 40%
- Net Profit: $20,000
Result: The contract gives you a 40% margin and $20,000 profit, making it a solid business opportunity.
