Knowing total labor cost after the job is done doesn't help you fix a problem mid-project. Tracking productivity per task while work is happening does.
=CrewSize*HoursWorked*HourlyRate gives the actual labor cost for that task.=UnitsCompleted/HoursWorked shows units produced per labor hour — the number that actually tells you if a crew is on pace, not just busy.=HoursWorked-BudgetedHours — a positive number means the task is running over its labor budget; conditional formatting (red for positive, green for negative or zero) makes this visible at a glance.=SUM(LaborCostColumn) at the bottom of the sheet gives a running weekly or per-phase labor total without needing a separate payroll summary.This turns labor tracking from a payroll afterthought into a live signal for whether a phase of work needs more crew, a schedule adjustment, or a hard conversation before it becomes a budget problem.
A four-person crew hangs drywall for 16 hours each at a $38 hourly rate and finishes 3,840 sq ft. The task was budgeted at 56 labor-hours.
| Measure | Formula | Result |
|---|---|---|
| Total labor-hours | =4*16 | 64 hrs |
| Labor cost | =4*16*38 | $2,432 |
| Productivity | =3840/64 | 60 sq ft per labor-hour |
| Cost per unit | =2432/3840 | $0.63 per sq ft |
| Overrun vs. budget | =64-56 | +8 hrs (over) |
Note that this example uses labor-hours, which means crew size times hours each person worked. Productivity is only meaningful when units are divided by total labor-hours, not by clock hours on the wall. If your Hours Worked column holds hours per person, multiply by the crew size first.
=AVERAGEIF(TypeColumn,"Drywall hang",ProductivityColumn) to see your crews' real average across jobs.Is tracking hours per task too much work for foremen?
It works best when the entry is quick. A simple daily sheet with task, crew size, hours and units complete takes a couple of minutes, and the data pays for itself the first time it prevents an underbid.
Should burden be included in the hourly rate?
For true job cost, yes. Use a loaded rate that includes payroll taxes, insurance and benefits, otherwise labor cost looks lower than it really is.
