What is a Drywall Labor Calculator?

A Drywall Labor Calculator is a tool that estimates:

• Labor hours required for drywall installation
• Labor costs based on hourly wage or contractor rates
• Number of sheets and workload based on square footage

It’s useful for:

• Contractors preparing bids
• Homeowners budgeting for renovations
• Project managers scheduling crews
• DIY enthusiasts planning home projects

Formula for Drywall Labor

The general formula for drywall labor is: Drywall Labor Hours=Total Square FootageCoverage Rate (sq. ft. per hour)\text{Drywall Labor Hours} = \frac{\text{Total Square Footage}}{\text{Coverage Rate (sq. ft. per hour)}}Drywall Labor Hours=Coverage Rate (sq. ft. per hour)Total Square Footage​

Then, to calculate labor cost: Labor Cost=Labor Hours×Hourly Rate\text{Labor Cost} = \text{Labor Hours} \times \text{Hourly Rate}Labor Cost=Labor Hours×Hourly Rate

If working by sheet: Drywall Labor Hours=Number of Sheets×Time per Sheet\text{Drywall Labor Hours} = \text{Number of Sheets} \times \text{Time per Sheet}Drywall Labor Hours=Number of Sheets×Time per Sheet

Example Calculations

Example 1 – By Square Footage

• Room: 20 × 10 × 8 ft (four walls + ceiling)
• Total surface = ~680 sq. ft.
• Coverage rate: 100 sq. ft. per hour
• Wage: $30/hour

680÷100=6.8 hours680 \div 100 = 6.8 \, \text{hours}680÷100=6.8hours 6.8×30=$2046.8 \times 30 = \$2046.8×30=$204

Labor Cost = $204

---

Example 2 – By Sheets

• Project requires 40 sheets
• Time per sheet = 0.35 hours (21 minutes)
• Hourly rate = $28

40×0.35=14 hours40 \times 0.35 = 14 \, \text{hours}40×0.35=14hours 14×28=$39214 \times 28 = \$39214×28=$392

Labor Cost = $392

Example 3 – Large Project

• 1,500 sq. ft. of drywall
• Coverage = 120 sq. ft./hour
• Wage = $25/hour

1500÷120=12.5 hours1500 \div 120 = 12.5 \, \text{hours}1500÷120=12.5hours 12.5×25=$312.5012.5 \times 25 = \$312.5012.5×25=$312.50

Labor Cost = $312.50
