The $35 vs. $72 Breakdown
Take a hypothetical lead worker at a $30M specialty contractor. Base pay: $35/hour, $72,800 annually. Now start adding layers.
| Cost Category | Annual Cost |
|---|---|
| Base Wages (2,080 hrs × $35) | $72,800 |
| Payroll Taxes (FICA, FUTA, SUTA) — ~10% | $7,280 |
| Workers' Comp Insurance — varies by trade | $8,700–$14,500 |
| Health Insurance (employer share) | $7,200–$12,000 |
| Vehicle (truck, fuel, maintenance, insurance) | $8,000–$12,000 |
| Phone, Tools, Equipment | $2,500–$4,000 |
| PTO, Holidays, Sick Days (~10 days) | $2,800 |
| Training, Certifications, Safety | $1,500–$3,000 |
| Total Loaded Cost (Midpoint) | $118,000–$133,000 |
| Effective Hourly Rate | $63–$72/hr |
That\'s the math. A $35/hour worker costs you somewhere between $57 and $72 per productive hour depending on trade, geography, and benefits. The multiplier ranges from 1.6x to 2.1x.
And that\'s if they're productive every hour you\'re paying them. (They're not. But we'll get to that.)
Most contractors look at that top number and flinch. You\'re thinking: "I only pay them $35." Exactly. You pay $35 in hourly wages. But that wage is just the anchovy in a much larger pizza.
The Hidden Labor Multiplier
The table above covers the obvious costs—the ones that show up on a payroll report. But there\'s a second layer of labor cost that almost nobody tracks.
Windshield Time
Your electricians drive 45 minutes to a jobsite. That\'s 90 minutes of paid time per worker per day where nobody is touching a tool. On a four-person crew, that\'s six paid hours a day spent driving. Over a year, that\'s roughly $45,000 in labor cost for transportation alone.
And that doesn\'t count the vehicle sitting idle, depreciating, burning fuel. This is pure non-productive labor cost that shows up in your P&L but not in the job cost.
Rework
Industry data suggests 5–10% of construction labor hours go to fixing work that was done incorrectly the first time. On a $3M labor budget, that\'s $150K--$300K in wasted effort. Rework doesn\'t show up as a separate line item. It hides inside your regular labor hours.
Sometimes it\'s a mistake on a pre-fab assembly. Sometimes it\'s a misread spec. Sometimes it\'s that your electrician had to redo conduit runs because the GC changed the layout mid-project. Whatever the reason, you\'re paying twice for work that should have happened once.
Callbacks
Post-completion warranty work and client callbacks pull your crew off revenue-generating jobs to fix problems on completed ones. Each callback costs you twice: the labor to fix it and the lost production on the job they were supposed to be doing.
Downtime Between Tasks
Waiting for materials, waiting for inspections, waiting for other trades to finish their work. National estimates put construction labor utilization at 40–60%—meaning your crew is productive less than two-thirds of their paid hours. On a $3M labor budget, 40% utilization means $1.2M goes to people standing around.
The Turnover Tax
Losing a skilled worker costs more than most contractors realize. When someone leaves, you\'re not just losing one person. You\'re losing continuity, knowledge, consistency, and momentum.
Here\'s what turnover actually costs: recruiting and hiring (2–4 weeks of admin time), onboarding and ramp-up (4–12 weeks at partial productivity), lost production and quality variance during the learning curve, and the institutional knowledge that walked out the door. Industry research suggests replacing a skilled tradesperson costs 50–100% of their annual loaded cost.
For a $72/hour loaded carpenter, that\'s $50,000--$100,000 per replacement. For a small contractor losing two people a year, that\'s $100K--$200K in direct turnover expense. The loaded rate is what makes this number visible—and what makes a retention raise of $5,000--$10,000 look like the investment it actually is. (Article 6 goes deep on turnover economics and retention strategies.)
How to Calculate Your Own Loaded Rate
Here\'s a simple formula you can run for your top three positions in the next 15 minutes:
Step 1: Gather direct costs
Pull the annual fully-loaded cost for one person: wages + payroll taxes + workers\' comp + health insurance + vehicle + tools + PTO + training. Use actual numbers from your payroll and accounting system, not estimates.
Step 2: Calculate productive hours
Start with 2,080 hours (52 weeks × 40 hours). Subtract: PTO/holidays (80–120 hours), sick time (24–40 hours), training (16–40 hours), estimated non-productive time (windshield time, waiting, downtime). A realistic number for most trades is 1,500–1,700 productive hours per year.
Step 3: Divide
Total loaded cost ÷ productive hours = true cost per productive hour.
Example: $125,000 total loaded cost ÷ 1,600 productive hours = $78.13 per productive hour. That\'s the real number. That\'s what each hour of actual wrench-turning costs your company.
The Loaded Rate by Trade
The multiplier between base rate and loaded rate varies significantly by trade. Here\'s what typical contractors see across common specialties:
| Trade | Typical Base Rate | Typical Loaded Multiplier | Loaded Hourly Rate* |
|---|---|---|---|
| Electrician | $40–$48/hr | 1.8x | $72–$86/hr |
| Plumber | $38–$46/hr | 1.7x | $65–$78/hr |
| HVAC Technician | $42–$50/hr | 2.0x | $84–$100/hr |
| Carpenter | $32–$40/hr | 1.6x | $51–$64/hr |
| Ironworker | $45–$55/hr | 1.9x | $86–$104/hr |
*Loaded rates include base wages, payroll taxes, workers\' comp, health insurance, vehicle/equipment, and non-productive time. Geographic variation can swing these 15–25% either direction.
These multipliers matter because they show that not all labor costs the same. HVAC and ironworkers carry heavier equipment and higher insurance, pushing their multiplier toward 2.0x. Carpenters, lighter on the benefits and vehicle side, come in lower at 1.6x. Use your actual trade mix to calculate your company-wide loaded rate.
What to Do With the Number
Knowing your loaded rate is step one. Using it is where the value lives. Here are four decisions this number directly informs:
1. Adjust Your Bids
If you\'ve been bidding jobs using the $35 base rate instead of the $72 loaded rate, you\'ve been underbidding by 50–100% on labor. Run this number into your estimating software. Every future bid becomes more accurate—and more profitable.
Common finding: Contractors who switch from base-rate to loaded-rate bidding typically see margins improve by 3–5 points on new projects within the first quarter. And that\'s before they optimize utilization.
2. Hire vs. Sub Analysis
When your loaded rate for an in-house electrician is $78/hour and a subcontractor quotes $85/hour, the math looks closer than you thought. Factor in consistency, quality control, and availability, and subbing might still cost more. But the margin narrows significantly when you use loaded rates.
Run the comparison: For each trade, compare your loaded hourly rate against the average sub rate in your market. If the sub is within 15% of your loaded cost, the decision becomes about capacity and control—not just price.
3. Retention ROI
When you know that losing a $72/hour loaded worker costs $50,000--$75,000 to replace (recruiting, ramp-up, lost productivity), a $5,000 retention raise has a 10:1 ROI. The loaded rate makes the retention math obvious.
Keep your top three people. The replacement cost alone justifies meaningful raises, better equipment, and schedule predictability. (For a deeper dive on retention strategies, see our article on the true cost of losing one skilled worker.)
4. Utilization Improvement
If your crew is productive 50% of paid hours, improving utilization by even 10 points (to 60%) is the equivalent of adding a half-person to every crew without hiring anyone.
Three quick utilization wins:
- Pre-stage materials the night before so nobody\'s waiting at 7 AM
- Batch inspections to reduce idle time between phases
- Cluster jobsites geographically to reduce windshield time
On a four-person crew at $72/hour, moving from 50% to 60% utilization adds 832 productive hours per year. At $72/hour, that\'s $59,900 in recovered labor value—from a crew you already employ. That money stays on your bottom line.
Real Example: Specialty Contractor, Four Crews
A $30M specialty contractor with four crews ran this exercise. They were stuck at 45% utilization across all crews. In a single quarter, they implemented: pre-staging (prep materials the evening before), inspection batching (consolidated inspections into two blocks per week instead of scattered calls), and geographic clustering (grouped jobsites by area to cut drive time from 90 minutes average to 45 minutes).
The result: utilization moved from 45% to 58%. That doesn\'t sound dramatic until you do the math. Across 16 crew members at $68/hour average loaded rate, 13 percentage points of utilization improvement equals 2,704 recovered productive hours per year. At $68/hour, that\'s approximately $184,000 in recovered labor value annually.
For a contractor operating on 8–12% net margins, that\'s pure profit. No new headcount. No capital investment. No change to the payroll or headcount model. Just better information and better scheduling discipline.
They didn\'t hire anyone. They didn\'t reduce payroll. They simply made the hours they were already paying for count more. And that\'s when the loaded rate concept becomes operational reality.
The Monday Morning Exercise
This week, calculate the loaded rate for your top three positions. It takes 15 minutes per position. Write down:
- The base hourly rate you think you\'re paying
- The actual loaded hourly rate (using the formula above)
- The multiplier (loaded rate ÷ base rate)
If the multiplier is above 1.8x, your labor is more expensive than you realized—and your bids, hiring decisions, and retention strategies should reflect that reality.
The number isn\'t bad news. It\'s information. And the contractors who know their true labor cost make better decisions than the ones who guess.
