A field-service call consumes paid time and vehicle capacity before onsite work begins. Dispatch coordination, outbound and return travel, truck cost, tolls, and the first diagnostic minutes all remain real costs even when the customer declines the repair. A trip charge gives those costs an explicit place in the price book instead of hiding them in parts or hourly labor.

The policy decision is broader than mileage. One business may recover a full round trip for each appointment; another may spread the return leg across a clustered route. Minimum charges protect short calls from falling below a workable floor, while gross-margin pricing converts the cost basis into a selling price that can also support overhead and profit.

Use a loaded labor rate that includes the employer's cost of wages and benefits, not only the technician's wage.
Use a vehicle rate that reflects the intended policy. A tax mileage rate can be a reference, but it is not automatically the operating cost of a specific fleet.
State clearly whether an approved repair receives all, part, or none of the trip charge as a credit.
Apply after-hours premiums consistently so dispatchers and customers receive the same rule.

A calculated quote is a price-book planning result, not a market mandate. Local competition, taxes, licensing, customer contracts, warranty obligations, route density, and job-specific risk can justify a different final price.

How to Use This Tool:

Choose a starting service profile, then replace every cost and route assumption with the current dispatch policy.

Select the Service profile and Market context. Profiles preload editable assumptions; market context affects only the broad comparison band, not the calculated charge.
Enter one-way distance and drive time, then choose the Trip billing basis: 100% for the outbound leg, 150% for a clustered-route allowance, or 200% for a full round trip.
Enter loaded technician and helper rates, vehicle cost per distance unit, dispatch overhead, included onsite minutes, tolls, parking, and permits.
Set the minimum charge and target gross margin, then choose the after-hours level, any fixed emergency premium, repair-credit policy, and quote-rounding increment.
Review Recommended trip charge, Cost basis, actual margin, and repair credit together. If the broad comparison band looks surprising, validate the local inputs rather than forcing the quote into the band.

Interpreting Results:

Recommended trip charge is the cost-and-margin result after the minimum floor, timing premium, fixed emergency premium, and selected rounding. Actual margin can differ slightly from the target because the minimum, premiums, and rounding operate after the cost-plus-margin calculation.

The included service radius does not reduce the main charge formula. It identifies the distance beyond the stated radius and supplies comparison scenarios. Likewise, the market benchmark is a repository-authored planning band; it does not modify the quote or prove that a price is competitive.

Technical Details:

The price model builds a direct cost basis from travel, included onsite labor, vehicle use, dispatch overhead, and route charges. Gross margin is applied by dividing by the fraction of selling price that remains after the target margin.

Formula Core:

The calculation uses these ordered equations:

\begin{array}{rcl} f & = & \frac{b}{100} \\ C & = & \frac{f t_{d}}{60} (r_{l} + h r_{h}) + \frac{t_{o}}{60} (r_{l} + h r_{h}) + f d r_{v} + A + T \\ F & = & \frac{C}{1 - \frac{m}{100}} \\ Q & = & round (\frac{\max (F, Q_{\min}) x + E}{q}) q \end{array}

b is the selected trip basis in percent and f its multiplier. One-way drive minutes and distance are t_d and d; included onsite minutes are t_o. Lead and helper loaded rates are r_l and r_h, with h helpers. Vehicle rate is r_v, dispatch overhead is A, tolls and parking are T, target margin is m, after-hours multiplier is x, fixed emergency premium is E, and q is the rounding increment.

Policy Rules:

Field service trip charge policy rules
Policy	Rule
After-hours	Standard 1×, evening 1.5×, weekend 2×, emergency 2×, or custom 1× to 4×
Full repair credit	Credits the recommended charge
Diagnostic credit	Credits margin-adjusted onsite labor plus dispatch, capped at the recommended charge
Travel credit	Credits margin-adjusted travel labor plus vehicle cost, capped at the recommended charge
No credit	Credits zero

All currency entries share the selected display currency; no exchange-rate conversion occurs. Quote rounding uses the nearest selected increment, so it can round either upward or downward. Target margin is accepted from 0% through 84%, preventing a zero or negative denominator.

Limitations:

Profiles and benchmark bands are editable planning heuristics, not surveyed local prices or legal guidance.
The result excludes tax, financing fees, bad-debt allowance, callbacks, warranty cost, parts handling, and job-specific risk unless you include them in the entered rates or overhead.
The optional IRS mileage rate is a tax and reimbursement reference, not a universal fleet-cost rate.
Review consumer-disclosure, tax, licensing, and repair-credit requirements for the jurisdiction and contract in use.

Worked Example:

A 12-mile HVAC dispatch with 20 minutes of one-way driving, a full round trip, a $72 loaded technician rate, $0.72 per mile vehicle cost, $24 dispatch overhead, 20 included onsite minutes, and a 42% target margin has a $113.28 cost basis. Cost plus margin is $195.31, above the $119 minimum. Standard-hours pricing rounded to the nearest dollar produces a $195 recommendation and an actual margin of about 41.91%.
