How do I spot add-ons packed into my car loan payment?

A dealer may offer extras on top of the car. If you finance them, they raise your payment and the amount you borrow. This checklist uses guidance from the CFPB and FTC to help you see what is in your deal.

The short answer

What add-ons are: the CFPB says they are "additional products or services offered by the dealer," and they "can add significant cost to the deal." They include extended warranties, service contracts and GAP.¹
What financing does: unless you pay cash, the CFPB says "the extra items will increase your monthly payment and the total amount financed on the car."¹
They are generally optional: the CFPB says add-ons are "generally optional, so you're not required to purchase them."¹
Check the paperwork: the CFPB advises making sure the contract "doesn't include items you don't want" and that any amount for an add-on you do want "is what you agreed on."¹

About the name "payment packing"

People sometimes use the phrase "payment packing" for add-ons that end up inside a car loan's payment. The CFPB and FTC pages do not use that phrase, and neither defines it as a legal term. This page uses the plainer wording "add-ons financed with the car." For the Canadian rules on a related practice, see our guide on dealer add-on bundling in Canada.

The checklist

Know what counts as an add-on. The CFPB lists physical items such as window etching, rustproofing, security items and accessories. It says add-ons "can also include extended warranties; service contracts; guaranteed auto protection (GAP); or tire, dent, paint, and fabric protection packages."¹
Look at the price of each add-on, not only the monthly payment. The CFPB says add-ons "may significantly vary in cost from dealer to dealer."¹ A service contract, it says, "may be arranged at any time and always costs extra."¹
See how financing changes the cost. Unless you pay cash for an add-on, it increases the monthly payment and the total amount financed.¹ For GAP bought from the dealer, "the amount is added to your amount financed, and you'll pay interest on it, increasing your monthly payments and total cost."¹
Read the contract line by line. The CFPB says to be "certain to review your contract to ensure it doesn't include items you don't want."¹ Its car-loan guidance says: "make sure the paperwork matches the deal you think you are getting and that everyone has signed all the documents."²
Remember you can say no. The CFPB says "Be ready to say 'No, thank you' if you're offered add-ons that you don't want or need."¹
Watch how the offer is made. The FTC says dealers "typically mention auto service contracts and other 'add-ons' after you've spent a long day at the dealership." It adds that they "may try to include them in the paperwork you must review, without discussing them with you, and without your understanding or approval."³
Avoid deciding on the spot. The CFPB says to "try to avoid making the decision on the spot in the dealer's finance office" for a dealer service contract.¹
Know where else the product is sold. The CFPB says "you can shop and compare alternative sources for most add-ons offered by the dealer," including payment options "that aren't financed with the car."¹
Ask whether you can cancel. The CFPB says "Certain add-ons may also be cancellable for a refund after purchase of the car."¹ For GAP it suggests finding out in advance what you need to do to cancel.¹

A note on the sources

The CFPB blog post is dated December 10, 2018. The CFPB marks it as archived and says the information "may be outdated." The CFPB auto loans page was last modified on September 25, 2026.¹² Check current federal and state rules before relying on any detail.

Related federal rules

Three of our guides cover rules that touch add-ons in a car loan. The FTC Holder Rule covers a financed service contract. The vacated FTC CARS Rule was written for dealer add-ons but is not in effect. GAP charges and Reg Z covers how a GAP charge is disclosed.

Where this fits in our standard

Points 1 and 7 of our standard ask about plain-language terms and about marketing that matches the contract. The Register shows how we check vehicle service contract providers. It describes a method, not a recommendation of any company.

How to verify this yourself

Read the CFPB blog post (reference 1) and the CFPB auto loans page (reference 2). The FTC page (reference 3) is the source of the statement about how add-ons are offered.¹²³
Compare your signed paperwork with what you were quoted. Each add-on should appear with its own price.
The CFPB auto loans page has a "Submit a Complaint" option.² The FTC takes reports at ReportFraud.ftc.gov.³

What this page is not

This is general information, not legal or financial advice. It reports what federal agencies say. It does not say whether any add-on is worth buying, and it does not assess any dealer or lender. State rules on add-ons differ.

What to do next

Before you sign, ask for each add-on to be listed with its own price, and read the contract against your quote. Our guides on comparing vehicle service contracts and GAP refund rights explain the terms. Start from the vehicle warranties hub or the scams and deceptive marketing hub.
