Twelve vans at one site can look like the perfect route: no driving between customers and a repeat booking on the calendar. But a contract that says “clean the fleet weekly” can quietly require a fifth visit, extra interior work or more vehicle types than you priced. Quote the number of vehicles, the exact number of visits and the cleaning scope before turning a per-van rate into a monthly promise.

Quick answer: Estimate paid technician-hours per vehicle and per site visit. Add supplies, travel, equipment use, account administration and a consistent share of overhead, then test the price against the visits and vehicle count named in the contract. In the illustrative example below, 12 vans cleaned on four visits cost $2,868 to service and support; billing $80 per vehicle-visit yields $3,840 and a modeled $972 surplus. A fifth visit included at no extra charge cuts that surplus to $470.

This guide prices a recurring group of vehicles at one account, not a one-off retail detail or an individual maintenance plan. See our mobile detailing maintenance-plan pricing guide for a recurring offer to individual customers.

Define the fleet service before calculating a price

Walk the lot and count the vehicles by class. A small sedan, cargo van and heavily used service truck can demand different work. Record interior condition, exterior wash method, cab access, equipment storage, water and power access, allowed work hours and how keys will be managed. Ask whether a vehicle may be unavailable during a planned visit and whether the client expects you to return for it. State which surfaces receive a basic clean and which stains, odor treatments, paint corrections or damage repairs are separate work.

Choose a billing unit that the client can understand: one vehicle cleaned on one scheduled visit. In this example the customer has 12 similar vans and buys exactly four scheduled site visits per billing month. That creates 12 × 4 = 48 vehicle-visits. A calendar month with a fifth weekly service is not included by that wording; define its price and approval process in the proposal. If the client actually needs every week of the year, you can instead price 52 annual visits divided into 12 equal payments, but the annual service count must appear in the agreement.

The numbers below are fictional USD assumptions for a worked calculation. They are not typical US detailing rates or a quote for any actual fleet.

Technician labor is 42 paid hours, not 42 hours on the wall clock if two people work at once: 48 × 0.75 = 36 vehicle-hours, plus 4 × 1.5 = 6 setup-hours. At $32 fully loaded cost per paid technician-hour, labor is $1,344. Use your own payroll and paid travel practice in place of $32.

At $80 per vehicle-visit, revenue is 48 × $80 = $3,840. Modeled surplus after all the listed costs is $3,840 − $2,868 = $972, or 25.31% of client revenue. The $600 is an allocated share of shared monthly overhead. It can make a contract-level full-cost estimate useful, but when you later run a business-wide break-even model, count that shared overhead in fixed costs only once.

Check the schedule before offering a volume discount

Fleet work is attractive when the route is dense and each vehicle fits the expected scope. It is less attractive when drivers move keys late, vehicles arrive muddy after a job or the team must wait for access. The estimate uses 45 paid minutes per van plus 1.5 paid setup/closeout hours per visit. One visit therefore takes 10.5 paid technician-hours (12 × 0.75 + 1.5). If two technicians are available, that does not automatically mean 5.25 hours on site: task handoffs, water access and parking can add elapsed time.

Promise a realistic service window. Record how many vehicles can be out of service simultaneously and whether your crew can move them. If client employees must hand over keys, agree on a ready-by time and on what happens to a vehicle not presented. Travel and equipment setup are paid once per visit in the base case; if the client requests a return visit for a missed van, that is a new trip, not simply another $8 of supplies.

To compare a discounted fleet rate with single-vehicle work, use contribution, not the retail sticker price. The 48 vehicle-visits each require $24 in technician vehicle time (0.75 × $32) and $8 supplies. At an $80 price, they leave $48 per vehicle-visit toward setup, travel, equipment, account administration and overhead. The shared monthly costs beyond per-vehicle labor and supplies total $2,868 − (48 × $32) = $1,332. A 48-visit contract contributes 48 × $48 = $2,304; after $1,332, the same $972 surplus remains.

This form makes a lower vehicle count visible. On unchanged four-visit trips, the modeled break-even number of vehicle-visits is $1,332 ÷ $48 = 27.75, or 28 completed vehicle-visits. That is seven vans on each of four visits. It is a mathematical threshold under the stated mix, not a reason to accept any seven-vehicle account: available parking, condition and access may change the costs.

Two changes that can consume the margin

A fifth visit with no additional bill. Another 12 vehicle cleans and one site setup cost 12 × 0.75 × $32 = $288 of vehicle labor, 1.5 × $32 = $48 setup labor, 12 × $8 = $96 supplies, $50 travel and $20 equipment. Extra cost is $502. If the price stays $3,840, total cost rises to $3,370 and surplus falls to $470, a 12.24% margin. A clear four-visit term avoids ambiguity. If the customer buys the fifth visit at the same $80 per vehicle, additional revenue is $960 and the five-visit modeled surplus becomes $1,430 on $4,800 revenue.

Fewer vehicles, same trips. If only nine vans are presented on each of four visits, there are 36 vehicle-visits. Per-vehicle labor and supplies cost 36 × $32 = $1,152. Add the same $1,332 of visit and monthly costs: total $2,484. Billing only 36 × $80 = $2,880 leaves $396, a 13.75% margin. To protect the economics, agree a minimum monthly account charge, a minimum count, or a separate trip/setup fee. Make the rule visible in the quote rather than surprising the customer later.

The $1,332 shared/visit cost assumes four trips in the reduced-count case. For the fifth-visit case, the extra setup, travel and equipment are added explicitly, so do not reuse $1,332 unchanged with 60 vehicle-visits.

Turn the calculation into a usable proposal

Name the account location, vehicle types, included interior and exterior tasks, maximum time or condition assumptions, the four dates or scheduling method, service window, client access duties, handling for missed vehicles and your change-order price for extra visits, oversize units or heavy cleanup. Say who supplies water/power, who handles waste and how completion is signed off. Set billing and payment terms so payroll can be paid before the invoice clears.

Vehicle washing can create wastewater; ask how the site handles it before quoting a method. The US EPA's vehicle maintenance and washing best-practice document explains the stormwater concern. Confirm the local site rules and applicable requirements rather than assuming a standard parking-lot wash is appropriate everywhere. If the service must use additional containment or an approved facility, price that method and travel into this specific account.

Save actual arrival times, vehicles cleaned, paid technician-hours, materials and return trips after the first few visits. A contract price can be corrected at renewal if your original quote was wrong; an extra or changed service should be handled through the agreed approval process.

How to run your own monthly break-even check

Use the mobile detailing break-even calculator with a representative completed vehicle service or account visit, its job-level variable cost, company-wide monthly fixed expenses and owner pay. Keep the account's $600 allocated overhead out of variable cost if those same shared expenses are already entered as monthly fixed costs. The calculator accepts currencies other than USD; the example here is simply in dollars.

Common mistakes

Calling four visits “weekly forever.” Four times per month and every seven days all year are different service promises.

Pricing only the time touching vehicles. Paid setup, closeout, waiting and key handling may occupy the crew even when no vehicle is being cleaned.

Offering a volume discount without a vehicle minimum. The same trip and setup cost can be spread over 12 vans or only nine.

Treating every van as identical. Condition, size and included interior work need defined classes or approved extras.

Ignoring site wastewater handling. A lower price based on an unsuitable wash method is not a useful quote.

Counting allocated overhead twice. Use it in the full-cost contract view or the monthly company break-even input, with consistent treatment.

FAQs

Should I quote per vehicle or per month?

You can show both. Calculate a cost per vehicle-visit internally, then state the exact vehicle count and scheduled visits behind the monthly price. Include a minimum or approved extra-visit price where appropriate.

What if the fleet has different types of vehicles?

Group them by actual service time and scope, then price each class or set a clearly defined mix assumption. A cargo truck with a dirty cab should not silently receive the same time allowance as a small van.

How do I handle a fifth weekly visit in a long month?

Define whether the contract includes four visits per billing month or a weekly schedule throughout the year. Price the fifth visit separately or build the full annual visit count into equal monthly payments.

Do I bill for a van that was not available?

Use the agreed minimum, readiness and rescheduling terms. If only completed vehicles are billed, test the reduced count while keeping unavoidable travel and setup costs in the model.

What is the break-even vehicle count in the example?

With unchanged four visits, each completed vehicle-visit contributes $48 after per-vehicle labor and supplies. The $1,332 visit/monthly base divided by $48 is 27.75, so 28 completed vehicle-visits, equivalent to seven vans across four visits.

Is the $972 surplus the owner's take-home pay?

Only if your cost model already includes the owner's planned pay and all other relevant company costs. If the owner is doing unpaid work in this model, add realistic compensation before calling the remainder a true operating surplus.

Takeaways

• Define four visits, 12 vans and the service scope before quoting a per-vehicle price.
• Model technician-hours, setup, supplies, travel and account overhead separately.
• Test a fifth visit and reduced vehicle count; both change the economics materially.
• Document minimums, extras, site access and wastewater method in the agreement.
