How the Labor Cost Calculator Works
Labor is the line that buries margin. A framing crew can hang 200 to 300 SF of wall per carpenter per day on open commercial framing — and 80 SF per carpenter on a retrofit with floor protection, occupied conditions, and limited material storage. Same headcount, same wage rate, three times the cost. The calculator math is simple; the productivity assumption is where the bid lives or dies.
Use this for crew-based labor budgets on a specific project: framing a single house, hanging drywall on a TI, finishing concrete on a slab. Reach for AGC labor surveys or your own job-cost history (not RSMeans defaults) for production rates when you can — the gap between national-average and your-crew-on-this-jobsite is usually the swing factor.
Crew cost build-up
- Labor hours = crew size x hours per worker
- Base labor cost = labor hours x wage rate
- Loaded labor cost = base labor cost x (1 + burden rate)
- Labor sell price = loaded labor cost x (1 + markup)
Estimating Steps and Checks
Build the crew sheet
List every role on the crew with headcount, base wage, and expected hours. Foreman, journeyman, apprentice, and operator are four different costs — and four different production rates per hour.
Stack burden trade-by-trade
Workers comp class codes alone can swing labor cost 15 percent or more between framing (high mod) and admin (low mod). Apply the right WC rate and any union or prevailing-wage fringe per the wage determination.
Adjust hours against site reality
Multiply baseline production hours by inefficiency factors: occupied building (1.10x to 1.25x), shift work or compressed schedule (1.05x to 1.15x for overtime fatigue plus the wage premium), winter conditions north of latitude 40 (1.10x to 1.30x in January), restricted access (1.10x to 1.40x).
Stack overhead and fee on top
Allocate overhead per labor hour the way your G&A actually behaves, then apply the markup that hits target margin (not target markup — see the markup calculator).
Common Checks
- Use loaded labor in bids; bare wage in payroll. Mixing them up is the most common source of margin slip — burden alone can be 30 percent of the line.
- Overtime is a double hit: 1.5x the wage and roughly 0.85x to 0.90x the productivity after week one. Price both explicitly or it disappears into the bid.
- Watch out for the crowding limit: more workers in a tight space stop adding output around 1 worker per 200 to 300 SF on most trades.
- Field check: track actual hours per CSI division on every closed job. After three jobs you have a production rate that beats anything in a published catalog.
Labor Cost Calculator FAQs
How do I estimate labor cost for a specific construction task?
Take the production rate (SF per crew-hour, lf per crew-hour, or units per crew-hour), divide the quantity by the rate to get crew-hours, multiply by crew size to get labor hours, then load it with wage, burden, overhead, and markup. Track actuals to refine the production rate next bid.
What labor burden should I use if I do not have a CPA-built number?
A reasonable open-shop floor is 25 to 30 percent (FICA + FUTA + SUTA + WC + a thin benefit load). 35 to 45 percent is common with health, retirement match, and PTO. Signatory union work with full fringes can hit 60 to 80 percent. Always use your actual number once you have one.
When should overhead live in the labor line versus a separate line?
For bids, fold it into the labor sell price so every hour recovers its share. For job costing and P&L, keep direct labor and overhead in separate buckets — that is the only way to know if margin slipped on field execution or office burn.
My labor estimates keep coming in low — where do I fix it?
Almost always in productivity, not the wage rate. Walk three closed jobs, calculate actual production rates per task, and replace your default catalog numbers with field reality. Then add explicit risk lines for difficult access, occupied conditions, and weather windows.
