Construction Labor Calculator

Work quantity. Enter the amount of work to be completed in the unit selected below. For example, a square-foot quantity must be paired with square feet per worker-day. Only the linear-foot option accepts length fractions and explicit feet/inches.

Quantity unit. Choose the unit that describes the work and the production rate. Keep both on the same basis: square feet, linear feet, individual items or cubic yards. This choice does not supply a trade-specific production rate.

Production per worker-day. Enter the amount one worker can complete in one workday of the duration entered below. Use comparable job records or a considered project estimate. Do not enter the whole crew’s daily output, because crew size is applied separately.

Crew size (workers). Enter the whole number of workers expected to work at the individual production rate. Increasing the crew reduces estimated duration, but does not reduce the total worker-hours of effort. Real crews may not scale proportionally where access or sequencing limits the work.

Working hours per day. Enter the working hours in the worker-day used to establish your production rate. If you change the day length, reconsider whether the daily production figure should change too. Breaks, overtime and calendar scheduling are not added automatically.

Hourly labor cost (USD / worker-hour). Optionally enter the cost of one worker-hour on the basis you want to estimate. Include payroll burden or other labor costs in your rate if they belong in your estimate; they are not added separately. Leaving this blank omits the cost result.

Worker-days describe total labor effort. Crew-days divide that effort among the entered workers and indicate working duration, not dates on a calendar. Worker-hours remain the same when only crew size changes. Optional cost uses those total hours and your hourly rate; it includes only the costs represented in that rate.

Worker-days = quantity ÷ production per worker-day.
Crew working days = worker-days ÷ crew size.
Labor hours = worker-days × working hours per day.
Labor cost = labor hours × hourly labor cost.

Worked example: 1,000 sq ft at 250 sq ft per worker-day requires 4 worker-days. A two-person crew needs 2 working days. At 8 hours/day, effort is 32 worker-hours; at $35/hour, estimated cost is $1,120.

Planning estimate only. Productivity and cost depend on the trade, job conditions, crew coordination, and scope. Assumes workers perform at the same rate and crew output scales proportionally. No overtime, calendar, or automatic productivity adjustment.
