What Is Job Costing?

Job costing tracks all expenses (labor, materials, overhead) for a specific project. It helps contractors price jobs accurately, identify profitable work, and avoid under-bidding that leads to losses.

Industry Benchmarks

  • Overhead:Typically 10-20% for small contractors, 20-35% for larger firms
  • Profit:Most contractors target 10-25% net profit margin
  • Labor:Usually 40-50% of total job cost in construction

How to Calculate Job Costs for Contractors

Job costing is the process of tracking all costs associated with a specific project to determine profitability and create accurate bids for future work. For contractors, accurate job costing is the difference between profitable growth and financial loss.

The Formula

Direct Costs = Labor + Materials + Equipment

Total Cost = Direct Costs + (Direct Costs x Overhead %)

Bid Price = Total Cost + (Total Cost x Profit %)

Why Job Costing Matters

According to the Construction Financial Management Association, contractors who implement job costing see an average 8-12% improvement in profit margins. Without it, many contractors unknowingly lose money on 20-30% of their projects. Job costing helps identify which types of work are most profitable and where costs can be reduced.
