Quick Answer: How to Calculate Construction Labor Cost
Construction labor cost = (hourly rate x crew size x daily hours x job days) x (1 + burden rate). A 3-person crew at $38/hour working 8-hour days costs $912 per day in base wages. Add a 30% burden rate and the real cost is $1,186 per day. Enter your rates and project length above to get an exact breakdown with overtime, burden, and totals.
Labor Rates by Trade (2026 Ranges)
Base hourly wages before burden. The burden column shows example assumptions inside the common 25-40% range, not measured trade averages; use your own payroll numbers.
| Trade | Base Hourly Rate | Example Burden | Burdened Rate |
|---|---|---|---|
| Laborer / Helper | $18-$28/hr | 25-30% | $23-$36/hr |
| Carpenter | $20-$45/hr | 30-35% | $26-$61/hr |
| Plumber | $30-$31/hr | 30-40% | $39-$43/hr |
| Electrician | $30-$31/hr | 30-40% | $39-$43/hr |
| HVAC Technician | about $29/hr | 30-40% | $38-$41/hr |
Electrician, plumber, and HVAC wages are the national median base wage (BLS, May 2025). Licensed shops bill homeowners $50-$150/hr for electrical and plumbing work, and HVAC contractors bill $75-$150/hr; that is a billing rate charged to the client, not a wage. Rates vary widely by region; high-cost metros run above these national figures and rural markets below them. Use local payroll data when you have it.
How Much Does Construction Labor Cost Per Day?
Based on a blended $38/hour base wage, an 8-hour day, and a 30% burden rate. This is what the crew actually costs you before markup, not what you charge the client.
| Crew Size | Base Cost / Day | Burdened Cost / Day | Burdened Cost / Week |
|---|---|---|---|
| 1 worker | $304 | $395 | $1,976 |
| 2 workers | $608 | $790 | $3,952 |
| 3 workers | $912 | $1,186 | $5,928 |
| 4 workers | $1,216 | $1,581 | $7,904 |
| 5 workers | $1,520 | $1,976 | $9,880 |
Weekly figures assume five 8-hour days with no overtime. Anything past 40 hours in a workweek gets paid at 1.5x.
Labor Cost Per Square Foot by Trade
Labor only, no materials. These are typical installer labor prices quoted to homeowners, so they already include the installer's overhead and profit; your own burdened cost should come in below them. Use these to sanity-check a bid before you send it, then replace them with your own job-costing history as you build it.
| Trade | Labor Cost / Sq Ft | What Drives the Range |
|---|---|---|
| Framing (whole house, per sq ft of floor area) | $11-$30 | Wall height, roof complexity, engineered members |
| Drywall (hang, tape, finish) | $1-$3 | Finish level, ceiling height, texture |
| Interior painting | $1.50-$3.50 | Prep work, number of coats, trim and doors |
| LVP / laminate install | LVP $2-$6 / laminate $3-$8 | Subfloor prep, transitions, room shape |
| Hardwood install | $3-$5 | Nail-down vs glue, pattern, stair nosing |
| Tile setting (floor) | $8-$15 | Tile size, layout pattern, waterproofing |
Roofing labor is priced per square (100 sq ft), not per sq ft. Figure $150-$300 per square in most markets to install asphalt shingles, up to $150-$500 per square across the full range of conditions, plus about $100-$125 per square for one layer of tear-off.
What Makes Up a Contractor's Burden Rate
Burden is every dollar you pay above the base wage. A $35/hour carpenter never costs $35/hour. Many contractors use 25-40% as a starting point, but your real number depends on your payroll taxes, workers' comp class, and benefits. Here is where it comes from.
| Burden Component | % of Base Wage | Notes |
|---|---|---|
| FICA (Social Security + Medicare) | 7.65% | Fixed employer share: 6.2% + 1.45% (IRS Topic 751) |
| Workers' compensation | Varies | Widely by trade class code, state, and claims history. Use the rate on your policy |
| Unemployment (FUTA + SUTA) | Varies | FUTA is 0.6% on the first $7,000 of each employee's wages after the state credit (IRS Topic 759); SUTA rate and wage base vary by state and your experience rating |
| Health insurance | Your cost ÷ base wages | Zero if you don't offer it. Big swing factor |
| Paid time off and holidays | Your cost ÷ base wages | Hours you pay for but don't bill |
| Retirement match | Your cost ÷ base wages | Optional, but it keeps good crews |
| General liability and other | Your cost ÷ base wages | Policy cost allocated per payroll dollar |
Run your actual payroll through the burdened labor rate calculator to get your real number. Guessing at a flat 30% is how contractors quietly lose money on every hour they bill.
Worked Example: Labor on a 2-Week Bathroom Remodel
A 3-person crew, $38/hour blended base wage, 30% burden. Ten working days of 8-hour shifts, plus 6 hours of overtime each in week one to hold the tile schedule.
- Regular wages: $38 x 3 workers x 80 hrs = $9,120
- Overtime: 6 hrs x 3 workers x $38 x 1.5 = $1,026
- Burden at 30%: ($9,120 + $1,026) x 0.30 = $3,044
- Total burdened labor: $13,190
Bid that same job off the base wage alone and you'd have written $9,120 on the estimate. That's a $4,070 hole before you buy a single piece of tile. The burden and the overtime are the two line items contractors forget, and they're the two that decide whether the job made money.
Where Labor Estimates Go Wrong
- 1.
Bidding the base wage instead of the burdened rate
A $35/hour carpenter costs about $44-$49/hour fully loaded at a 25-40% burden once you add FICA, workers comp, unemployment, and benefits. Bidding the base rate means you lose roughly $9-$14 per hour across every crew member, every hour of every job.
- 2.
Forgetting non-productive time
Travel to the job, morning setup, material staging, cleanup at end of day, and waiting on inspections or deliveries eat into every 8-hour day. Your crew isn't building for 8 straight hours. Time it on your own jobs and factor that into your production rates.
- 3.
Using national averages instead of your local market
Labor rates swing widely between markets. Carpenter pay in a high-cost metro can run well above the national median, and rural markets run well below it. Use your own payroll data or local prevailing wage surveys, not national averages from a search result.
- 4.
Miscounting overtime exposure on long jobs
Any hours over 40 in a workweek get paid at 1.5x. On a job with a tight deadline where you push the crew to 50-hour weeks, that's 10 hours at time-and-a-half per worker. For a 4-person crew at $40/hour base, the overtime premium alone is $200 extra per worker per week, $800 across the crew, or $1,040 once you add a 30% burden.
- 5.
Not tracking labor cost per square foot by trade
The most accurate estimators track their own historical cost per sq ft for every trade on every job. After 10-20 jobs, you know your tile guys run $11/sq ft for field tile and noticeably more for glass mosaic. That data beats any published guide. Use a job costing spreadsheet to capture it as you go.

How Much Does Construction Labor Cost Per Hour in 2026?
Construction base wages run from about $18/hr for entry-level laborers to $45/hr for experienced carpenters, with electricians and plumbers at a national median of about $30–$31/hr (BLS May 2025). Licensed shops bill homeowners $50–$150/hr for electrical and plumbing work, and HVAC contractors bill $75–$150/hr; that is a billing rate, not a wage.
- General laborer: $18–$28/hr
- Carpenter: $20–$45/hr (national median about $29.12/hr, BLS May 2025)
- Electrician: about $30–$31/hr national median wage (BLS May 2025)
- Plumber: about $30–$31/hr national median wage (BLS May 2025)
- HVAC technician: about $29/hr national median wage (BLS May 2025)
These are base wage rates. The actual cost to employ workers (burdened rate) is typically 25–40% higher after taxes, insurance, and benefits.
Key Takeaways
- Electricians/plumbers: about $30-$31/hr national median wage
- General laborers: $18–$28/hr
- Burdened rate = base wage + 25–40%
What Is a Burdened Labor Rate?
The burdened labor rate is the true cost of an employee per hour, including wages plus all employer-paid taxes, insurance, and benefits.
- FICA (Social Security + Medicare): 7.65% of wages, fixed (6.2% + 1.45%)
- Workers' compensation: varies widely by trade class code, state, and claims history; use the rate on your policy
- Unemployment insurance (FUTA/SUTA): FUTA is 0.6% on the first $7,000 of each employee's wages after the state credit; SUTA rate and wage base vary by state and your experience rating
- Health insurance, PTO, retirement match, general liability: your actual cost divided by base wages; these vary by what you offer
Rule of thumb: Many contractors land between 25% and 40% total burden, but your real number depends on your payroll taxes, workers' comp class, and benefits. Run your own payroll through the burdened labor rate calculator instead of guessing.
Key Takeaways
- Burdened rate = wage × 1.25–1.40 for most contractors
- FICA is fixed at 7.65%; workers comp and unemployment vary by state and trade
- Run your real payroll numbers instead of guessing at 30%
How to Estimate Labor Hours for Construction Projects
Use your own job-costing history as the foundation for labor estimates, then adjust for site conditions. Published production-rate tables vary too much by crew, tooling, and site conditions to bid off directly.
Add your own measured non-productive time (travel, setup, staging, cleanup, waiting on inspections or deliveries) on top of the productive-hours estimate, based on what you've tracked on past jobs rather than a fixed percentage.
Key Takeaways
- Build labor estimates from your own job-costing history
- Add your own measured non-productive time, not a guessed percentage
- Track actual vs. estimated hours to improve accuracy

Frequently Asked Questions
What is a labor burden rate?
Labor burden rate is the additional cost on top of an employee's hourly wage that covers payroll taxes, workers' compensation insurance, health benefits, retirement contributions, and other employer-paid expenses. It is typically expressed as a percentage of the base wage.
What is a typical labor burden rate for construction?
Many contractors use 25% to 40% of the base wage as a starting point, but your real number depends on your payroll taxes, workers' comp class, and benefits. Components include FICA (a fixed 7.65%), workers' comp (varies by trade class and state), unemployment insurance (varies by state), and whatever health and retirement benefits you offer. Run your own payroll numbers through the burdened labor rate calculator instead of guessing.
How is overtime calculated for construction workers?
Under the Fair Labor Standards Act (FLSA), overtime is paid at 1.5 times the regular hourly rate for hours worked beyond 40 in a workweek. Some states and union agreements add their own overtime rules, including daily overtime; check your state labor department.
How do I estimate labor hours for a construction project?
Use historical data from your own past projects as the primary source, break the project into tasks and estimate hours per task, and use industry labor productivity guides (like RSMeans) only as a starting check since crew, tooling, and site conditions vary too much to bid off a published table directly. Add a contingency for delays, weather, and rework, sized from your own job history.
Should I include burden rate in my bid?
Yes. Your bid must include the fully burdened labor cost, not just the base hourly rate. Leaving burden out means every hour you bill costs you more than you priced it. This calculator adds burden so it doesn't get left off the bid.
What is the average construction labor cost per hour in 2026?
Construction labor rates vary widely by trade and region. General laborers and helpers typically run $18-$28/hour base wage. Carpenters run $20-$45/hour (national median about $29.12, BLS May 2025). Electricians and plumbers run about $30-$31/hour national median wage; licensed shops bill homeowners $50-$150/hour for that work, which is a billing rate, not a wage. Add 25-40% burden on top of those base rates to get your actual cost per hour for estimating purposes.
How do I calculate labor cost per square foot of construction?
Divide your total burdened labor cost by the project square footage. For a 500 sq ft basement finish with $14,000 in total labor, that's $28/sq ft. For new construction, whole-house framing labor typically runs $11-$30/sq ft of floor area, and tile work $8-$15/sq ft. Track this number on every job to build your own historical benchmarks.
How much does a 3-person crew cost for a week?
A 3-person crew at $38/hour average working 40-hour weeks costs about $4,560 in base wages per week. Add 30% burden and you're at $5,928 per week fully loaded. At 35% burden, it's $6,156 per week. For a 2-week bathroom remodel with no overtime, budget about $11,860-$12,310 in labor ($9,120 in base wages plus 30-35% burden) before materials or markup; add more if the schedule requires overtime.
What is the average labor cost for construction?
Burdened cost runs about $23-$36/hour for general laborers, $26-$61/hour for carpenters, and about $39-$43/hour for electricians and plumbers at national median wages, before regional adjustment. The rest of a job's cost is materials, equipment, overhead, and profit.
How much does construction labor cost per day?
At a blended $38/hour and a 30% burden rate, one worker costs about $395 per 8-hour day fully loaded. A 2-person crew runs $790/day, a 3-person crew $1,186/day, and a 4-person crew $1,581/day. Multiply by your job length to get total labor. Long days push crews past 40 hours in a week, and every hour over 40 is paid at 1.5x.
How do I calculate my burden rate?
Add every employer-paid cost above the base wage, then divide by total base wages. That includes FICA (a fixed 7.65%), federal and state unemployment, workers' compensation, general liability, health insurance, retirement match, and paid time off, each of which varies by your state, trade class, and benefits. Many contractors land between 25% and 40%. Run your own payroll numbers through the burdened labor rate calculator instead of guessing at 30%.
How much does roofing labor cost per square?
Roofing labor typically runs $150-$300 per square (100 sq ft) in most markets, up to $150-$500 per square across the full range of conditions, and tear-off adds about $100-$125 per square for one layer. Steep pitch, multiple layers, and bad access push it higher. See the full breakdown in our roofing labor cost per square guide, or size the roof first with the roofing calculator.
