How to Price Service Jobs (Without Leaving Money on the Table)
Most contractors price jobs one of two ways: gut feel or whatever the last guy charged.
Both leave money on the table. Not because you're greedy — because you're not accounting for the real cost of running your business. When you price a job at $200 and your actual cost is $155, you're working for $45. That's not profit. That's a rounding error.
Doesn't matter if you're a plumber, HVAC tech, electrician, or roofer. The math is the same. Here's how to price service jobs so you actually make money.
The 5 Costs to Account for Before Profit
Every job you do carries these costs whether you think about them or not:
1. Parts and Materials
The obvious one. But don't just count what you installed. Count:
- Parts you brought but didn't use (it's in your truck, it's inventory)
- Consumables: tape, connectors, wire nuts, sealant, fasteners, sandpaper
- Safety gear and disposables
This applies across trades. A plumber's solder and flux. An electrician's wire and boxes. An HVAC tech's refrigerant and fittings. A roofer's nails and underlayment. Small costs that add up over 200 jobs a year.
Rule of thumb: Add 10-15% to your parts cost for consumables and waste.
2. Labor (Your Real Hourly Cost)
If you pay yourself $35/hour, your labor cost isn't $35/hour. It's higher.
Here's why: you only bill about 60-70% of your work hours. The rest is drive time, estimates, callbacks, admin, parts runs. So your effective labor cost per billable hour is:
$35/hr ÷ 0.65 (billable ratio) = $53.85/hr effective cost
For a tech you're paying $25/hr with benefits ($4/hr) and payroll taxes ($3/hr):
($25 + $4 + $3) ÷ 0.65 = $49.23/hr effective cost
If you're pricing at $50/hr, you're barely covering your labor — before overhead.
3. Overhead (The Silent Killer)
Monthly costs that exist whether you work or not:
| Overhead Item | Typical Monthly Cost |
|---|---|
| Truck payment + insurance | $800-1,200 |
| Fuel | $300-600 |
| Tools and equipment | $100-300 |
| Software (FSM, accounting) | $100-300 |
| Phone and internet | $100-200 |
| Licensing and insurance (business) | $200-500 |
| Marketing/advertising | $200-1,000 |
| Office/storage | $200-800 |
| Total monthly overhead | $2,000-5,000 |
Divide your monthly overhead by your monthly billable hours. That's your overhead cost per hour.
Example: $3,000/mo overhead ÷ 120 billable hours = $25/hr overhead cost
4. Drive Time
The most under-priced cost in home service. You spend 30-60 minutes getting to a job. Gas, wear on the truck, your time — none of it is free.
Options:
- Charge a trip/service fee ($50-95 is standard in most markets)
- Build drive time into your hourly rate (add $8-15/hr to cover average drive)
- Set a service area and charge more outside it
Don't eat drive time. It'll eat your margin.
5. Warranty and Callbacks
About 3-5% of jobs come back. Something leaks. A breaker trips. A unit makes a noise. You fix it for free because that's how you keep customers.
Build it in. Add 3-5% to every job price. That way, the 95% of jobs that go right pay for the 5% that don't.
Flat Rate vs Time and Materials
Two pricing models. Each has a place.
Time and Materials (T&M)
- Charge for actual hours worked + parts at markup
- Customer sees the clock running
- Better for: unpredictable jobs (remodels, diagnostics, old houses with surprises)
- Risk: customer anxiety about the bill growing, pressure to rush
Flat Rate
- Quote one price before the work starts
- Customer knows the cost upfront
- Better for: standard jobs (equipment installs, common repairs, system replacements)
- Risk: you eat the loss if the job takes longer than expected
The math that matters — using a water heater install as an example:
| T&M at $95/hr | Flat Rate | |
|---|---|---|
| Standard install (3 hrs, $400 parts) | $285 labor + $520 parts (30% markup) = $805 | $950 flat |
| If job takes 4 hours | $380 + $520 = $900 | Still $950 |
| If job takes 2 hours | $190 + $520 = $710 | Still $950 |
Same math works for an HVAC condenser swap, a panel upgrade, or a roof repair. Flat rate rewards efficiency. T&M rewards slow work (unintentionally).
Most successful residential service shops under $2M revenue use flat rate for standard jobs and T&M for unknowns.
How to Build a Price Book
A price book is a list of every common job with a set price. It eliminates guessing and ensures every tech quotes the same number.
Step by step:
-
List your 20 most common jobs. Every trade has its bread-and-butter work:
- Plumbing: Water heater install, faucet replacement, drain clearing, toilet repair, garbage disposal
- HVAC: AC tune-up, furnace repair, thermostat install, condenser replacement, duct repair
- Electrical: Outlet install, panel upgrade, ceiling fan install, breaker replacement, whole-home surge protection
- Roofing: Leak repair, shingle replacement, flashing repair, gutter install, ridge vent install
-
For each job, calculate:
- Average parts cost (with 10% buffer)
- Average labor hours (add 15% for the ones that run long)
- Your overhead cost per hour
- Your profit target (15-25% net on top of all costs)
-
Set the flat rate price.
Example — Ceiling fan installation (electrical):
- Parts: $0 (customer-supplied fan) + $15 (wire nuts, mounting hardware, consumables) = $15
- Labor: 1.5 hours x $54/hr (effective cost) = $81
- Overhead: 1.5 hours x $25/hr = $37.50
- Subtotal cost: $133.50
- 20% profit margin: $26.70
- Flat rate price: $165 (round to clean number)
- Load it into your estimating software. When a customer calls for a ceiling fan install, you don't think. You quote $165.
Trade-Specific Pricing Benchmarks
Rates vary by market, but here are rough ranges for residential service work in 2026:
| Trade | Typical Hourly Rate | Common Service Call Fee | Average Job Value |
|---|---|---|---|
| Plumbing | $85-150/hr | $50-85 | $250-800 |
| HVAC | $75-150/hr | $75-95 | $150-500 (repair), $3,000-8,000 (install) |
| Electrical | $80-130/hr | $50-75 | $150-500 (repair), $1,500-4,000 (panel/rewire) |
| Roofing | $50-80/hr (per crew) | N/A (bid jobs) | $300-1,000 (repair), $8,000-15,000 (replacement) |
Don't set your rate based on competitors. Set it based on your actual costs plus your target margin. If your costs are higher, your prices need to be higher. That's math, not greed.
How to Raise Prices Without Losing Customers
You need to raise prices. Your costs went up. Gas went up. Parts went up. But you're charging the same rates from 2 years ago.
Here's how to do it without losing everyone:
1. Raise prices 5-8% for new customers immediately. They don't know your old prices. Just set the new rate.
2. Notify existing customers with a letter or text. Be straight: "Starting March 1, our service call rate is moving from $85 to $95. Material and fuel costs have increased, and this lets us keep the same quality of work and response time you're used to."
3. Don't apologize. You're running a business, not a charity. Good customers understand costs go up. The ones who leave over $10 weren't profitable anyway.
4. Raise prices annually. Small increases every year are easier to absorb than a big jump every 3 years. Make it routine.
