The total hours the job is expected to take, per worker.

The number of workers billed at this hourly rate.

If different crew members bill at different rates, run this calculator once per rate and add the totals.

What this calculation does not cover

  • One rate is multiplied across every hour and every worker, so there is no tier for overtime or holiday premiums, night and weekend differentials, or a crew that pairs a licensed lead with an apprentice — a mixed-rate job has to be totalled in separate runs and added by hand.
  • Crew size acts as a straight multiplier on the hours you entered, which assumes each additional worker stays productive for the full duration: the tasks that will not split across two pairs of hands, the time a crew loses coordinating, and the helper who is only on site for part of the week all leave the total untouched.
  • Nothing distinguishes a wage you pay from a rate you are charged, because the same multiplication runs on either. A figure built from raw wages carries no payroll taxes, workers' compensation, insurance or benefits on top of it, while a contractor's quoted rate may already have overhead and profit buried inside — the answer looks identical in both cases.
  • Only worked hours are priced. Travel and mobilization, setup and clean-up, tool or equipment hire, disposal, permits and materials all sit outside the figure, and no minimum charge is imposed either — an entry of half an hour returns half an hour of money on a job many trades would bill as a minimum visit.
  • The hours you type are taken exactly as they stand, with no contingency for rework, weather, waiting on an inspection or scope that grows once the walls are open, and the rate is held flat for the whole span — a long program approaching the 2,000-hour entry ceiling is still priced at today's number, with no escalation partway through.

  • Applications for Payment, and the Notices That Followuses this calculator

    Application nine went in five weeks ago and nothing has come back. Whether a valid pay less notice ever existed, and what falls due if it did not.

  • Building Up a Unit Rateuses this calculator

    A rate is a quotient, and the quantity underneath it was measured by somebody else to rules you have not read. Everything else is the easy half.

  • Delay, Notice and Extension of Timeuses this calculator

    A fortnight lost to weather and a late instruction. Which of them buys time, which also buys money, and the notice that has to go before either does.

How to calculate labor cost in 4 steps

  1. Estimated HoursThe total hours the job is expected to take, per worker.
  2. Hourly RateThe rate charged (or paid) per worker, per hour.
  3. Crew SizeThe number of workers billed at this hourly rate.
  4. Estimated labor costThe tool computes the estimated labor cost from those figures and shows the formula, its sources, and a confidence rating alongside it.

Frequently asked questions

Does this include materials cost?
No — this is labor only. Use the Renovation Budget Calculator or Cost Per Square Foot Calculator alongside this one to build a fuller project estimate, or add material line items in the Project Builder.
Should I use my own hours or the total crew-hours?
Enter the hours the job takes per worker (i.e. the job's duration), not the total crew-hours — this calculator multiplies by crew size for you.
How do I account for overtime rates?
Run this calculator twice — once for regular hours at the standard rate, once for overtime hours at the overtime rate — and add the two totals together.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
