How the contractor estimate is calculated
Estimated project cost
Direct cost + overhead + contingency
Price before tax
Estimated project cost + markup
Estimated gross margin
Gross profit ÷ price before tax × 100
Use true labor cost
Use a burdened labor rate that includes payroll taxes, insurance, benefits, paid time off, and non-billable time—not wages alone.
Account for overhead
Include a reasonable allocation for office costs, vehicles, software, insurance, management, and other expenses not assigned directly to one job.
Verify tax treatment
Sales tax rules differ by jurisdiction and contract type. Confirm which labor, materials, and services are taxable before issuing a final estimate.
