Trailer hitch installation cost calculator
Work out what installing a trailer hitch will cost from the hitch, the wiring, and the labor. A basic hitch is inexpensive and often bolts to existing holes; the electrical wiring for lights and brakes, and the labor to route it, are where the bill is really decided. The calculator adds up your quote.
Typical range $378 – $601
- Hitch (part)$200
- Wiring harness$80
- Labor (hours × rate)$165
- Ball mount, brake controller & extras$0
- Total$445
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.
THE HITCH IS CHEAP; THE WIRING AND THE LABOR ARE THE BILL.
The hitch class must match what you tow, and it is a safety line, not a price choice. A light Class I hitch for a bike rack is not a Class III or IV for a loaded trailer. Buying a hitch rated below your load is dangerous; buying well above it wastes money. Match the class to the trailer's loaded weight and your car's tow rating, whichever is lower.
A braked trailer needs a brake controller, and that adds cost. Trailers above a certain weight have their own brakes, which require a controller wired into the car and a 7-pin connector rather than a simple 4-pin. If you tow a braked trailer, the controller and the heavier wiring are a real add, not optional.
A DIY bolt-on install is realistic for a simple hitch, and it is most of the saving. If your car has existing frame holes and a plug-in harness, fitting the hitch yourself is a driveway job with hand tools, and the labor is the line you avoid. Custom wiring or drilling is where a professional earns the fee.
The trailer hitch defaults are ours and a starting point you can edit. The hitch, the wiring, and the labor are yours, and the estimate turns most on whether your car has a tow-package connector or needs the wiring spliced in.
