How to Use This Calculator
- Enter the base labor-hours per unit under ideal conditions from your productivity standards or historical data.
- Enter the crew size and total quantity of units to install or construct.
- Set the weather, overtime, and site congestion factors (1.0 = ideal; increase toward 1.3 for severe conditions).
- Enter the base hourly wage and burden multiplier (typically 1.30–1.50 for taxes, insurance, and benefits).
- Read the adjusted hours per unit, total crew-days, total labor cost, and labor cost per unit.
How the result changes with Base Labor-Hours / Unit
| Base Labor-Hours / Unit | Adjusted Hours / Unit | Total Labor Cost ($) |
|---|---|---|
| 100 | 100 | $1,215,000.00 |
| 350 | 350 | $4,252,500.00 |
| 650 | 650 | $7,897,500.00 |
| 900 | 900 | $10,935,000.00 |
What each input means
- Base Labor-Hours / Unit
- Standard labor-hours for one worker to complete one unit under ideal conditions.
- Crew Size
- Number of workers in the crew.
- Total Quantity (units)
- Total number of units to be installed or constructed.
- Weather Factor
- 1.0 = ideal, 1.10 = moderate, 1.20 = poor, 1.30+ = severe weather.
- Overtime Factor
- 1.0 = no overtime, 1.05 = occasional, 1.10 = regular, 1.15 = sustained OT fatigue.
- Site Congestion Factor
- 1.0 = open site, 1.10 = moderate, 1.20 = congested, 1.30 = very congested.
- Hourly Wage Rate ($)
- Base hourly wage before burden (taxes, insurance, benefits).
- Burden Multiplier
- Multiplier for payroll taxes, insurance, and benefits (typically 1.30–1.50).
What each result means
- Adjusted Hours / Unit
- Labor-hours per unit after condition adjustments.
- Units / Crew-Hour
- Output rate: how many units the crew completes per hour.
- Total Worker-Hours
- Total individual worker hours for the entire quantity.
- Total Crew-Hours
- Calendar hours the crew will work.
- Crew-Days (8-hr)
- Number of 8-hour working days for the crew.
- Burdened Rate ($/hr)
- Fully loaded hourly cost per worker.
- Total Labor Cost ($)
- Total burdened labor cost for all work.
- Labor Cost / Unit ($)
- Burdened labor cost per installed unit.
- Productivity Efficiency (%)
- 100% = ideal conditions; decreases with adverse factors.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersBase Labor-Hours / Unit = 2.5, Crew Size = 4, Total Quantity (units) = 200, Weather Factor = 1 = 8 input(s) provided
- Calculate Adjusted Hours / UnitAdjusted Hours / Unit = baseLaborHoursPerUnit * combinedFactor2.5 = 2.5
- Calculate Total Labor CostTotal Labor Cost = totalWorkerHours * burdenedRate30375 = $30,375
- Calculate Units / Crew-HourUnits / Crew-Hour = crewSize / adjustedHoursPerUnit1.6 = 1.6
- Calculate Total Worker-HoursTotal Worker-Hours = adjustedHoursPerUnit * totalQuantity500 = 500
