Setting Your Hourly Shop Rate: Burdened Labor, Overhead, and Target Profit Math

Your shop rate is the foundation of every bid

Ask most contractors what their shop rate is and you'll get a range of answers from “I charge $85 an hour” to “I don't really use a shop rate, I just quote jobs.” Both are problems. Whether you quote flat-rate or T&M, whether you're residential service or commercial, every bid you produce has an implied hourly rate for your crew's time. When that implied rate is below what you actually need to run the business, you lose money on every job and make it up — sometimes — on volume.

This guide walks through the math from the ground up: burdened labor cost, overhead allocation, target profit, and the jump from what you pay your tech to what you charge for their hour on site.

Step 1: Wage vs. burdened labor cost

The first trap is confusing a tech's wage with your cost for that tech. If you pay a journeyman $32/hr, your actual cost is usually $45–$52/hr. The delta is labor burden.

This is the number you plug into every job cost. Not $32. If you quote jobs at $32/hr cost and your real cost is $49, you're eating $17/hr on every billable hour.

Step 2: Overhead allocation

Overhead is everything that doesn't vary with a specific job: rent, office staff, vehicle payments, fuel, office supplies, software subscriptions, insurance premiums, marketing, owner salary, depreciation, legal, accounting.

Compute annual overhead, then divide by annual billable hours to get an hourly overhead allocation.

Example: 4-tech residential service shop

• Annual overhead: $320,000 (rent, office staff, 4 service vans w/ fuel and maintenance, software, insurance, marketing, owner salary)
• 4 techs × 2,080 hours × 70% billable efficiency = 5,824 billable hours/year
• Overhead per billable hour: $54.94

That's what your company overhead costs on top of every billable hour. Small shops with heavy trucks, multiple locations, or high marketing spend can see overhead allocation of $70–$100/hr.

Step 3: Target profit

Profit is what's left after all the above is paid. Set it intentionally, not by accident. 2026 profit benchmarks for residential service businesses:

• Surviving: 5–8% net profit
• Healthy: 10–15% net profit
• Thriving: 18–25% net profit
• Best-in-class: 25%+ (usually flat-rate residential service with strong brand)

If your target is 20% net profit, you need the equivalent of $0.25 of profit for every $1 of cost (because profit = revenue − cost, and $0.25 / $1.25 = 20%).

Shop rate math: put it together

Formula

Shop rate = (burdened labor + overhead per billable hour) ÷ (1 − target net margin)

Example

• Burdened labor: $48.92
• Overhead per billable hour: $54.94
• Cost per billable hour: $103.86
• Target net margin: 20% → divide by 0.80
• Required shop rate: $129.83 → round to $130/hr

Miss the overhead calculation and your rate will be $75/hr, which looks competitive, covers burdened labor, and delivers zero profit. Skip the profit target and you'll hit $104/hr — back to breaking even after a busy year.

The hidden variable: billable utilization

The single most impactful number in your shop rate calculation is billable utilization — the percentage of payroll hours that actually show up on an invoice.

Increasing billable utilization from 60% to 75% has the same effect on your shop rate as cutting overhead by 20%. This is why scheduling software, dispatching, and tight route planning have outsized ROI — every percentage point of billable time pulled forward is money.

Reconciling shop rate with flat-rate pricing

Flat-rate pricing is not an exception to shop rate — it's a derivative. Each flat-rate task has a standard time estimate. The price is: (standard time × shop rate) + materials + markup. Your book should implicitly bake in the shop rate.

Example: a ceiling fan install has a standard time of 1.25 hours. At $130/hr shop rate, that's $162.50 labor equivalent, plus $15 materials plus markup → ~$265 flat rate price.

When you raise your shop rate, you raise the flat-rate book accordingly. If your book stays flat while your costs rise, margin silently erodes.

How often should you review your shop rate?

Once a quarter minimum, fully annually at year-end. Triggers for an off-cycle review:

• Wage increases for techs
• Health insurance renewal (usually big)
• Insurance premium renewal
• Lease increase
• Adding a new service location or truck
• Fuel cost shifts of more than 15%
• Any new software contract or tool purchase that affects overhead

Shop rate mistakes

1. Using wage instead of burdened cost. Always use fully-burdened cost. Wage is the starting point, not the cost.
2. No overhead allocation. Overhead exists; if you don't allocate it to billable hours, you silently absorb it in profit.
3. Ignoring billable utilization. A shop running 50% billable has a very different shop rate than one running 75%. Both are valid but only if the math matches reality.
4. Benchmarking against competitor rates. Your competitor's rate is their cost structure, not yours. Do the math for your business, then decide how to position.
5. Reviewing once every three years. Costs move every year. Review quarterly, adjust at minimum annually.
