Price a trade service call from labor hours, hourly rate, trip fee, parts, and target margin.

About the Service Call Pricing Calculator

Every trade business lives or dies on how it prices a service call. Underprice and you are working for free after truck, tools, and drive time; overprice and you lose the job to the shop down the road. This calculator helps plumbers, electricians, HVAC techs, and appliance repair pros build a defensible quote by stacking labor, a trip or diagnostic fee, and parts with markup into a single invoice total.

The three revenue streams behave differently, and lumping them together hides where the money comes from. Labor pays for the skilled time on site, the trip fee recovers the fixed cost of dispatching a truck and diagnosing the problem, and parts markup covers procurement, stocking, warranty risk, and the profit on materials you front.

By breaking the quote into those parts, the tool shows not just the customer-facing total but also the profit baked into the parts markup, so you can see whether a job is actually worth running or whether your rate needs to move. It is a quick way to standardize pricing across a crew instead of every tech guessing.

How the Service Call Pricing Calculator works

Labor is the simplest line: labor total = hours on site x your hourly rate. This should be your billable shop rate, which already bakes in overhead, insurance, and profit, not your technician's raw wage.

Parts are marked up over cost: parts total = parts cost x (1 + markup percent / 100). The difference between that and your raw cost is the parts profit, shown separately so you can see the dollars the markup actually generates. A 30% markup on $140 of parts, for instance, yields $42 of gross parts profit.

The trip or diagnostic fee is added as a flat amount that recovers the fixed cost of showing up, dispatch, fuel, and the diagnostic time. The invoice total sums all three: labor + marked-up parts + trip fee. Change any input and every line and the total recalculate.

Worked example

Picture a 2.5-hour repair billed at a $95 hourly shop rate, a $75 trip and diagnostic fee, and $140 in parts marked up 30%. Labor comes to 2.5 x 95 = $237.50.

Parts are 140 x 1.30 = $182.00, of which $42.00 is the markup profit above your $140 cost. The trip fee stays at $75.

Adding them up: $237.50 labor + $182.00 parts + $75.00 trip fee = a $494.50 total invoice. The tech can see at a glance that beyond the labor, the job also earns $42 on parts, which helps justify keeping common parts stocked on the truck.

Tips & common mistakes

Set your hourly rate as a fully burdened shop rate, not the tech's pay. It has to cover wages plus payroll taxes, vehicle costs, insurance, tools, office overhead, and profit, which is why shop rates run two to three times the technician's wage.
Do not skip the trip fee to win a job. It recovers real fixed costs of dispatching a truck; giving it away means the first hour of every call subsidizes the customer.
Standard parts markups in the trades run 25% to 50% or more on common items and higher on small, hard-to-source, or warranty-heavy parts. Flat-rate shops often build even more margin into a menu price.
For quick diagnostic calls, consider folding the first portion of labor into the trip fee so a five-minute fix still covers your time on site, then bill hourly beyond that.
Round the final invoice to a clean number and present it as one total to the customer while keeping the labor, parts, and fee breakdown handy in case they ask what they are paying for.

Service Call Pricing Calculator: frequently asked questions

What should my hourly service rate be?

Charge a fully burdened shop rate that covers technician wages plus overhead, vehicle costs, insurance, tools, and profit, typically two to three times what you pay the tech. If your loaded costs are $40 an hour, a rate of $90 to $120 is common in most trades to stay profitable.

How much should I mark up parts?

Common markups run 25% to 50% on standard materials and higher on small, specialty, or warranty-heavy parts. The markup covers procurement time, stocking, warranty risk, and profit on materials you finance up front. In the example, a 30% markup on $140 of parts adds $42 of gross profit.

What is a trip or diagnostic fee for?

It recovers the fixed cost of dispatching a truck and diagnosing the problem regardless of whether a repair follows: fuel, drive time, and the tech's time to assess the issue. Many shops credit this fee toward the repair if the customer approves the work, which is worth stating up front.

Should the trip fee be credited toward the repair?

Many shops apply the diagnostic fee to the final bill when the customer proceeds with the repair, which makes the fee feel fair and encourages approval. Others keep it separate. Either policy works as long as it is disclosed before the visit so there are no billing surprises.

How do I know if a job is profitable?

Look at more than the total. Labor should exceed your loaded hourly cost, the trip fee should cover dispatch, and the parts profit line shows the markup dollars. If labor barely beats your costs and parts profit is thin, the job is marginal and your rate or markup needs to rise.

Should I use hourly pricing or flat-rate?

Hourly, as modeled here, is transparent and fair on unpredictable jobs. Flat-rate pricing quotes a fixed menu price per task and rewards efficient techs while giving customers a firm number. Many shops use hourly for diagnostics and complex work and flat-rate for common, well-understood repairs.
