The first time a customer asks "how much?" and there's no boss standing behind you to answer it, most new solo tradesmen freeze for a second, then guess. The guess is usually too low, because underpricing feels safer than losing the job — and it's the single fastest way to work seventy hours a week and still not make rent. This guide isn't about confidence tricks or "charge what you're worth" pep talks. It's the arithmetic.
To price a job as a new solo tradesman: set three numbers before you quote anything — a labor rate built from your target take-home income divided by your realistic billable hours (not your calendar hours), a materials markup on top of what parts actually cost you, and a service-call fee that gets you paid for showing up and diagnosing the problem even if the customer says no to the repair. Multiply labor hours by your rate, add marked-up materials, add the service-call fee where it applies, and round to a firm number. That's the whole method — the rest of this guide is how to fill in each piece honestly, plus a worked example and a look at when the method doesn't apply.
None of this requires software. Every number below can be worked out on paper before you ever open an app. But because testing the math on a real job list beats testing it in your head, the end of this guide links a free tool that reprices a real sample job as you change your numbers, no signup.
The Three Numbers You Need Before Your First Quote
Every price you say out loud is built from the same three inputs. Get these right once and every quote after your first gets faster, not slower.
- Labor rate — what you charge per hour of work, built from what you need to earn and how many hours you can actually bill, not your calendar.
- Materials markup — a percentage added to what parts cost you, kept as a separate line from labor so raising one number doesn't force you to re-price the other.
- Service-call fee — a flat charge for showing up and diagnosing the problem, so a "just looking" call and a wasted trip aren't unpaid work.
Skip any one of the three and the gap shows up somewhere: skip the labor-rate math and you guess low under pressure; skip the markup and materials quietly eat your profit; skip the service-call fee and every no-sale diagnosis is time you gave away for free.
Your Labor Rate: From Take-Home Income to an Hourly Number
Your labor rate is not your old hourly wage from working for someone else. It's every dollar the business needs, per hour you actually bill, to pay you and keep the truck running. The formula is simple; the honesty required to fill it in is the hard part.
Take-home income you actually want — not revenue, the number that lands in your account after the business pays its own bills. Pick a real target for your first year, not an aspirational one.
Annual overhead — insurance, tools, vehicle costs, licenses, phone, basic marketing — add it up as a yearly number, separate from what you want to take home.
Realistic billable hours — this is where new tradesmen most often overshoot. A general contractor rate calculator from Housecall Pro puts it plainly: "Most independent contractors are only billable for 60–70% of their working hours," which turns a 40-hour week into roughly 24–28 billable hours (source). In your first year, expect the low end of that range or below it — driving to unfamiliar addresses, estimates that don't close, and a client list that isn't full yet all eat into billable time before you've built a routine.
Add your take-home target to your annual overhead, divide by your realistic billable hours, and you have a floor. It's a floor, not a final answer — check it against what other solo operators in your trade actually charge before you quote it. As one electrical-contractor pricing guide puts it, fully burdened labor rates in the trade commonly run "$85–150 per hour" (source); if your own math lands far outside that kind of range for your trade and market, that's a signal to recheck your inputs, not to quietly split the difference on the job in front of you.
Illustrative only, not a recommendation: a new solo tradesman targeting $55,000 take-home in year one, carrying $9,000 in annual overhead (insurance, tools, an older work truck, a phone line, basic licensing), and realistically billing 900 hours that first year — a below-40%-of-calendar-hours number, deliberately conservative for a client list that isn't full yet — lands at ($55,000 + $9,000) ÷ 900 = $71.11/hour. Rounded up to a number he can say out loud, that's $75/hour, before checking it against what other solo operators in his trade and area are actually charging.
Materials Markup: Keep Parts and Labor Separate
Price materials as their own line, marked up over what you actually paid — never bundled invisibly into the labor number. A flat markup (25% and 30% are both common starting points) is easy to apply consistently and easy to explain if a customer asks what a part cost. Keeping the two numbers separate also means a supplier price increase only touches the materials line, not a full re-price of every job in your head.
The Service-Call Fee: Getting Paid to Show Up
This is the number new tradesmen skip most often, and it's the one that costs the most in year one. Every diagnosis takes real time and real drive time, whether the customer says yes to the repair or not. A service-call fee — sometimes called a trip charge or diagnostic fee — covers that time up front, and it's standard practice, not an upsell.
Published ranges cluster tightly: ServiceTitan's own guidance states "diagnostic fees vary shop to shop, but a typical range is $75 to $150" (source), and the electrical-contractor pricing guide cited above recommends the same "$75–$150" band for a flat diagnostic/trip fee before presenting flat-rate repair options (source). FieldEdge frames the same fee structurally rather than by price: charge for "the travel to the customer's house and the first 15 minutes on the job," so the clock on paid diagnosis starts the moment you arrive (source).
The common, customer-friendly practice: if the customer approves the repair, credit the service-call fee toward the job total instead of charging both in full. It softens the ask at the door and still means a diagnosis that doesn't turn into work was never unpaid.
Hourly vs. Flat Rate: Which Should a Beginner Actually Use
Neither one, exclusively — and the honest answer is the same one the industry's own pricing guides land on. Housecall Pro's HVAC pricing guide splits it by predictability: flat-rate for "standard repairs, tune-ups, and common replacements" where materials and labor are known upfront, and hourly or time-and-materials for "diagnostic and troubleshooting calls" where the issue is unclear before you look at it (source). The electrical pricing guide above describes the same split as a hybrid: "charge a flat diagnostic/trip fee ($75–$150)... then present flat rate options for the repair" (source).
For a beginner specifically, that hybrid is the easier and safer starting point than picking one model for everything. Charge the service-call fee to walk in the door and diagnose. Once you know exactly what the job needs, quote it flat — a fixed number the customer can say yes to on the spot. Fall back to hourly or time-and-materials only for the jobs where even you don't know the scope yet; guessing a flat number on an unknown job is how new tradesmen eat the difference on their own paycheck.
A Worked Example: Pricing Your First Real Job
Take the labor rate from the illustration above — $75/hour — a 30% materials markup, and an $85 service-call fee. A customer calls about a dead kitchen outlet.
Illustrative only, not a recommendation: you arrive, diagnose a failed GFCI receptacle in twenty minutes, and the fix is a straightforward swap: 45 minutes of labor and a receptacle that costs you $16. Labor: 0.75 hours × $75 = $56.25. Materials: $16 × 1.30 = $20.80. Job total: $77.05. Round up to $80, and since the customer is proceeding with the repair, the $85 service-call fee is credited toward it rather than charged on top — so the number you say out loud is $80, not $165. If the diagnosis had turned up nothing repairable, or the customer had declined the fix, the $85 service-call fee is what you'd charge for the visit, full stop — not zero.
That's the entire method in one job: labor hours × labor rate, plus materials × markup, plus the service-call fee where it applies, rounded to a number you can say without hesitating.
When Not to Flat-Rate a Job
Flat rate is for the job you've now done enough times to know its shape — typical labor hours, a predictable parts list. It's the wrong tool for anything you're seeing for the first time on your truck: a full rewire, a repipe, fire or water damage repair, anything where the scope depends on what you find once the wall is open. Quoting those flat is a guess wearing a firm number, and if the guess is wrong, you eat the difference silently or have an awkward conversation mid-job — the exact standoff flat-rate pricing exists to avoid. For that 20% of the work, hourly or time-and-materials, priced with your own judgment on the day, is the honest answer. As you do more of a given job type, it graduates from "custom, price it live" to "template it, quote it flat" — that's the normal life cycle of a price book, not a sign you did something wrong at the start.
Common Pricing Mistakes New Tradesmen Make
Quoting off a competitor's number instead of your own costs. Someone else's price reflects their overhead, their billable hours, and their market — not yours. Use competitor pricing as a sanity check on your final number, never as the starting formula.
Forgetting the service-call fee entirely. A month of "just looking" diagnoses at zero dollars is a month of real drive time and real labor given away. If you don't charge for the visit, the price of every job that does close has to quietly cover the ones that didn't — and you'll never see that math on paper to catch it.
Counting calendar hours as billable hours. Forty hours on your calendar this week is not forty hours you can bill. New businesses especially: budget for the lower end of realistic billable-hour ranges until your client list is actually full, not the number that makes the labor-rate math look easier.
Flat-rating a job you've never done before. The first time is not the time to guess a firm number. Price it hourly or time-and-materials once, learn what it actually took, then template it for next time.
