Labor Cost Percentage Calculator

Calculate labor cost as a percentage of project revenue or contract value and compare against trade-specific industry benchmarks.

Calculation Results

Labor-to-Revenue Ratio Formula

Labor Percentage = (Total Direct Labor Cost / Total Contract Revenue) × 100
  • Healthy Painting Benchmark: 60% to 80% labor (high labor intensity, low material costs).
  • Healthy Framing Benchmark: 30% to 45% labor.
  • Healthy General Contracting Benchmark: 20% to 35% direct labor.
  • Assessment: Flags whether your labor costs are within healthy industry profitability ranges.

Step-by-Step Worked Example

Scenario: A general contracting job with $48,000 in total labor on a $160,000 contract revenue

Calculation Steps:

  1. Labor Percentage = ($48,000 / $160,000) × 100 = 30.0%
  2. Non-Labor Percentage = 100% - 30.0% = 70.0%
  3. Industry Benchmark Range = 20% to 35%
  4. Status = Healthy (within target operational range)
Result: Direct labor accounts for 30.0% of revenue, comfortably within the healthy 20%–35% benchmark range.

Assumptions & Limitations

  • Estimates are based on standard national averages and current prevailing construction materials and contractor rates.
  • Actual trade bids may fluctuate according to local building code requirements, permit fees, and site topography.
  • Always obtain multiple written bids from licensed, bonded, and insured contractors before commencing work.

Frequently Asked Questions

What happens if labor percentage is too high?

When labor exceeds trade benchmarks (e.g. framing labor exceeding 50%), it usually points to crew inefficiencies, scope creep, unbilled change orders, or underestimating installation time.
