Start a Business Service

What does it cost to start a detailing business?

Estimate what it takes to start a car detailing business, from the polisher, extractor and pressure washer through the van or trailer, the water tank and generator a mobile rig needs, the wrap and signage, chemical and pad inventory, insurance and licensing, booking and launch marketing, and the working capital you hold while the book fills. See the total, a realistic range, and how many vehicles you have to detail before the build has paid for itself.

§ 01 Your numbers

Change anything. The answer updates as you type.

Dual-action and rotary polishers, a hot water extractor for interiors, a shop vacuum, air blowers, lighting that shows swirls honestly, steamer, clay and cutting media, and the hand tools that go with them. Inspection lighting is the item people skip and then regret, because you cannot correct paint you cannot see and a customer will find the defect in their own driveway.
A commercial pressure washer, foam cannon, hoses and reels. A homeowner unit will do a handful of cars and then start failing on duty cycle, which is the same money spent twice. If you are running mobile, pick the unit around what your generator can actually carry rather than around the pressure rating on the box.
The rig itself, whether that is a used cargo van, a work truck, or an enclosed trailer behind something you already own. Put zero here if you are working from a vehicle you own or starting from a fixed bay. This is usually the largest single line and the one where a patient used purchase changes the whole total.
A water tank and pump, a generator sized for your extractor and washer together, a water heater if you want hot water on site, deionised or filtered water for spot-free rinsing, plus shelving and tie-downs so the load stops moving. This is the line that separates a mobile detailer who can work on any site from one who is limited to sites with an outdoor tap and a spare outlet.
Only if you are taking a fixed bay: security deposit, first months of rent, lighting, drainage, air lines and compressor, and whatever the shell needed. Leave this at zero for a purely mobile start. A bay buys weather independence and ceramic and paint correction work that needs controlled conditions, and it converts a variable cost into rent you owe every month regardless of the schedule.
Opening inventory of soaps, degreasers, iron removers, compounds and polishes, dressings, sealants or coatings, plus pads, towels and applicators in enough quantity that you are not washing towels between two jobs on the same day. Towels alone surprise people; a single interior-heavy job can consume a stack of them.
Vehicle wrap or lettering, logo, uniforms, business cards and yard signs. A wrapped rig parked in a driveway for four hours is advertising to the whole street, which is why detailers rate it above paid advertising in the early months. Partial lettering costs a fraction of a full wrap and does much of the same work.
General liability, garage keepers or care-custody-and-control cover for vehicles in your hands, commercial auto on the rig, the business licence, and entity formation. Care-custody cover is the one that matters here and the one a general liability policy often excludes: if you burn through clear coat on a customer's paint, that is the policy that answers.
Booking and scheduling software, payment processing, a site with real before-and-after photos of your own work, local listings and the first advertising push. Detailing is sold on photographs, so budget for shooting your early jobs properly rather than for stock images of somebody else's car.
Fuel, chemical restock, pad and towel replacement, insurance, software, phone, any rent, and loan payments in a normal month. Consumables scale with vehicles detailed rather than with the calendar, so a busy month costs more to run than a slow one and the reserve below has to cover the slow one.
How many months of that operating cost you hold in reserve. A detailing book fills on repeat customers and referrals, and both take a season to compound. Treat a small figure here as the thing to fix before you buy the rig, not after.
What a typical job bills, blended across quick interior-and-exterior work and the longer correction or coating jobs. Used only for the payback figure under your total, not added to the ledger. Be honest here rather than optimistic: the headline coating price is not what most of your calendar will look like in year one.
Roughly what share of a job's price goes back out in chemicals, pads and towels. Used with the average ticket to work out what each vehicle actually contributes toward the startup cost. Correction and coating work runs higher here than a maintenance wash, because compounds, pads and coatings are consumed in quantity.

$12,000 to $60,000 is where a purpose-built mobile operation lands: a bought van or trailer, a tank and generator that make you independent of the customer's tap, a full tool and chemical inventory, a wrap, and a reserve that covers a real ramp. The rig itself is usually the majority of it.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

EVERY NUMBER HERE IS YOURS, BECAUSE A POLISHER IS A PRICE AND NOT A STATISTIC.
The tools, the rig, the wrap, the chemical inventory and the insurance rating are all prices somebody quotes you for your list, your vehicle and your state, and they differ enough between two towns that a national average would mislead you rather than help. There is no federal source to look them up in, so we would rather itemise our own model in front of you than dress it up as a measurement. Every default above is ours and every one is editable. Price a real supplier basket, get a quote on the rig you actually intend to buy, and ask a carrier what care-custody cover costs where you are, then type those in.

The binding constraint is hours, not equipment. A tunnel wash puts a car through in minutes and the machine does the work; a detail is one person's hands for something between a couple of hours and a couple of days, and those hours run one after another rather than in parallel. That is why the figure under your total is counted in vehicles rather than months. Growing past your own calendar means hiring somebody and training them to your standard, which is a different and harder problem than buying a second polisher.

Mobile and bay are two different businesses wearing one name. Mobile trades rent for a rig that has to carry its own water and power, and it loses days to weather and to customers with no space to work in. A bay trades that for rent you owe whether the schedule is full or not, and it buys back the controlled conditions that ceramic coatings and serious paint correction want. The two lines are separate above precisely so you can price the fork rather than blur it, and many detailers start mobile and add a bay once the coating work justifies it.

Care-custody cover is the insurance line that actually matters, and general liability often excludes it. General liability answers for the customer who trips over your hose. It typically does not answer for the vehicle in your care that you damaged while working on it, which is the loss that ends a young detailing business. Ask a carrier specifically about garage keepers or care, custody and control on vehicles in your possession, and price it into the insurance line above rather than assuming one policy covers both.

Consumables are a share of each job, not a monthly bill. Compounds, pads, towels and coatings leave with every vehicle, so a busy month costs more to run than a quiet one and a correction job costs far more in materials than a maintenance wash. The materials percentage above exists so the payback figure counts what a job contributes rather than what it bills, which is why a headline ticket price flatters the arithmetic if you use it raw.

Frequently asked questions

Can I start mobile with equipment I already own?
This is the usual honest starting point, and it takes a large amount out of the ledger above. If you own a vehicle that can carry a rig, set the vehicle line to zero, keep the tank and generator line because self-sufficiency is what lets you take jobs at an office park rather than only at cooperative driveways, and spend the difference on tools and inventory that hold up under repeat use. What you should not economise on is the polisher, the inspection lighting and the insurance, because those three are where a cheap decision turns into damaged paint on somebody else's vehicle.
Mobile or a fixed bay first?
Mobile first, in most cases. It puts far less capital at risk, it lets you find out whether the demand in your area is there before you owe rent, and the convenience is genuinely part of what customers are paying for. A bay earns its rent once a meaningful share of your calendar is paint correction and ceramic coating work, which wants dust control, stable temperature and lighting you cannot get in a driveway, and once weather is regularly costing you days you would otherwise have billed. Price both lines above and look at what the bay actually adds to the total before committing to one.
How much should I charge per vehicle?
Price the hours rather than the vehicle. Work out what an hour of your time has to earn to cover the monthly operating cost above plus a wage worth working for, then estimate the hours a given package genuinely takes on a vehicle of that size and condition, and add the materials it consumes. A neglected interior is not the same job as a maintained one and should not carry the same price, which is why detailers who quote from a photograph before seeing the vehicle tend to lose money on the roughest cars they take.
What is the biggest cost people leave out?
Two things. The first is the mobile power and water fit-out, because a generator that can carry an extractor and a pressure washer together costs meaningfully more than one that can carry either alone, and the discovery usually happens on a job. The second is the working-capital reserve: fuel, chemicals and insurance start immediately, referrals compound slowly, and the reserve line above is what keeps you from pricing desperately in month three because the calendar is thin.
