How to Pay for a Custom Roof Rack and Cargo Box

Get your gear sorted for the spring rush without draining your savings account all at once.

Typical cost $1,200 before anything else
Across the 0% window $80.00/mo 15 months, no interest

How we got that: $1,200 spread evenly across the 15-month introductory window on the Discover it® Cash Back. Checked · at the bank Carry a balance past the window and the standard APR applies to what is left.

A custom roof rack turns a small car into a hauler, but the setup costs add up fast once you factor in the crossbars, mounts, and a quality cargo box. Expect to drop around $1200 for a solid, reliable build that won't whistle at highway speeds.

Timing matters here. Shops often have better inventory and shorter wait times in late winter before the spring travel rush hits. Negotiate the price of the installation separately from the hardware, as labor is where you have the most room to bargain.

Remember that the 0% intro APR is a deadline, not free money. If you have a remaining balance on the card after the 15 months are up, you will start paying interest on whatever is left, which will quickly negate any benefit of the payment plan.

The steps

  1. 01

    Size up your needs

    Measure your roof clearance and consider what you are actually hauling. A box that is too big will kill your gas mileage and make parking in garages impossible. Stick to what you need rather than the biggest model they sell.

  2. 02

    Shop for the hardware

    Look for gear in the off-season to find deals. Check local marketplaces for used crossbars, but always buy the mounting hardware new to ensure the fit is secure. A bad fit is a safety risk.

  3. 03

    Use the financing window

    If you need to spread the cost, the Discover it® Cash Back card offers 0% intro APR for 15 months on purchases. This gives you a 15-month window to pay off the $1200 without interest charges. At $80 per month, you can clear the debt before the next spring season.

  4. 04

    Negotiate the install

    If you are not comfortable drilling or mounting it yourself, find a local shop. Ask them for a flat labor rate rather than hourly billing. Mention you have your own parts, as some shops will lower the price if they aren't managing the supply chain.

  5. 05

    Test your clearance

    Before heading out on a trip, drive through your home garage or a local parking deck. Note the new height of your car on a piece of tape on your dashboard. This prevents a very expensive mistake on your first outing.

  6. 06

    Check the card terms before you commit

    Every figure we publish for the Discover it® Cash Back carries the date a person verified it against Discover and a link to where they checked. Intro windows and APRs change without notice, so confirm the current terms before applying.

Common questions

Will a roof rack ruin my gas mileage?

Yes, you will see a drop in fuel efficiency because of the extra wind drag. Expect to lose a few miles per gallon, especially when the cargo box is mounted.

Should I buy a used cargo box?

Used boxes are fine as long as the locking mechanism works and the shell isn't cracked. Check the seals around the hinges to make sure your gear stays dry during rain.

Do I need a professional to install this?

Most modern racks are designed for DIY, but a pro can ensure the weight is distributed correctly. If you are drilling into the roof, pay for the install to avoid leaks.

What happens if I miss a monthly payment?

Missing a payment can void your 0% intro APR offer immediately. Always set up an autopay for at least the minimum amount so you stay in good standing.
