Check your car contract for junk fees and add-ons

Education, not legal advice. We explain how dealer charges work and do the math. Your contract and your state’s law decide. For legal advice, talk to a lawyer or your local legal aid office.

Bought or leased a car and not sure what all those lines are? Here’s what each junk fee and add-on is, what’s negotiable, what you can cancel for a refund, and the math. You ask and send everything yourself; we never contact the dealer.

Why trust this: VaultRubric’s owner spent 11 years in dealership sales and management, including how the finance office builds a deal. Every rule here links to an official source.

Best first move

  1. Get your papers. The buyer’s order, the loan contract (the retail installment contract), and the separate contract for each add-on.
  2. Circle every line that isn’t the car, tax, or title and registration. Use the list below to see what each one is.
  3. Didn’t agree to it, or told it was required? Call the dealer’s finance manager and ask them to take it off and redo the contract. The sooner, the easier.
  4. Bought something you don’t want? GAP, service contracts and similar products can usually be cancelled in writing for a prorated refund.
  5. No luck? Complain for free: the CFPB for your lender, and the FTC and your state attorney general for the dealer.

What your add-ons really cost

With interest, they cost

$3,676.32

That’s $51.06 a month, and $681.32 of interest on top of the $2,995.00 price.

Example filled in: $2,995 of add-ons rolled into a 72-month loan at 7% APR. Add up every add-on line on your contract, then use your contract's APR and number of payments. Paid cash? Enter 0 months. (CFPB, CFPB)

Show the math
  • Payment for the add-ons alone: $2,995.00 at 7% APR for 72 months = $51.06 a month
  • $51.06 × 72 months = $3,676.32
  • Interest on the add-ons: $3,676.32 − $2,995.00 = $681.32
  • Add-ons really cost: $2,995.00 + $681.32 interest = $3,676.32

Formula: payment = add-ons × r ÷ (1 − (1 + r)−months), r = APR ÷ 12 ÷ 100, rounded to the cent. Interest = payment × months − add-ons. Your real loan may differ by a few cents.

Your refund if you cancel

Estimated refund

$621.25

Price × months left ÷ term, minus any fee.

Example filled in: an $895 GAP for 72 months, cancelled after 18 months, with a $50 cancellation fee. Your product's contract says how the refund is figured; this is an estimate. (CFPB, CFPB)

More: fee, miles and claims

Service contracts often end at a time or mileage limit, whichever comes first.

Show the math
  • Months left: 72 − 18 = 54 of 72; by months: $895.00 × 54 ÷ 72 = $671.25
  • Minus cancellation fee: $50.00
  • Refund estimate: $621.25

Line by line: what each charge is

Twelve lines dealers often add. The price of each is up to the dealer, and every add-on is optional. (CFPB, CFPB, FTC)

Key facts

  • Add-ons are optional. You generally can’t be required to buy an extended warranty, GAP or credit insurance to get a loan. If you’re told it’s required, ask where the contract says so. (CFPB)
  • No charging for what you didn’t agree to. The FTC says dealers can’t include charges for options you didn’t agree to, call an optional item required, or claim an installed option can’t be removed. (FTC, FTC)
  • Payment packing. The salesperson quotes a payment higher than the car alone needs, then fills the gap with add-ons, so the payment still “looks right.” The FTC described this in a 2024 case; that case was dismissed in October 2026 with no ruling either way. Check: does your payment match the car’s price, tax and fees alone? (FTC)
  • Rate markup. The lender gives the dealer a “buy rate.” Your rate can be higher, and the dealer keeps part of the difference. Your rate is negotiable. (CFPB, CFPB)
  • Loan ends early, money back. When a loan ends early, you’re generally owed a prorated refund of add-ons like GAP. If you paid the loan off, the refund goes to you; after a repossession, it goes toward what you still owe. (CFPB)
  • Still paying the loan? A refund usually goes to the lender and lowers what you owe. Ask the lender how it was applied. (CFPB, CFPB)

Where to look on your contract

  1. The Truth in Lending box. Four numbers: APR, finance charge, amount financed and total of payments. The APR is your real rate. (12 CFR 1026.18)
  2. The itemization of the amount financed. It lists money paid to others for you, like a service contract or GAP company. Each add-on should be there with its price. If it isn’t printed, you can ask for it. (12 CFR 1026.18)
  3. Credit insurance or a debt cancellation (GAP) form. These can stay out of the finance charge only if the form says they’re not required and you signed or initialed a separate request for them. (12 CFR 1026.4)
  4. Each product’s own contract. Find the “cancellation” section: who to send it to, the fee, and how the refund is figured.

How a cancellation refund works

  • Pro rata is the usual way: the price you paid × the part of the term you didn’t use. Some contracts use miles, or whichever runs out first.
  • Fees and claims: many contracts take off a small cancellation fee, and some take off claims already paid. Some states limit the fee.
  • Who to send it to: the administrator named on the product contract, with a copy to the dealer. Keep a copy and the date you sent it.
  • State rules: Tennessee, California, Texas and Washington have their own deadlines and fee limits. See the GAP and warranty refund guide.

FAQ

Can I get dealer add-ons taken off after I sign?

Often, yes. Call the dealer's finance manager first and ask them to remove anything you didn't agree to and redo the contract. Products like GAP and service contracts can usually be cancelled in writing for a prorated refund.

Do I have to buy GAP or an extended warranty to get a car loan?

Generally no. The CFPB says they're optional, and if a dealer or lender says one is required, ask them to show you where the contract says so.

How much refund will I get if I cancel my GAP or service contract?

Usually the price you paid times the share of the term you didn't use, minus any cancellation fee. Example: $895 x 54 of 72 months left = $671.25, minus a $50 fee = $621.25.

How much do add-ons cost with interest?

Use the standard loan formula. Example: $2,995 of add-ons at 7% for 72 months is $51.06 a month, or $3,676.32 in all: $681.32 of interest on top.

Is the dealer doc fee negotiable?

It's a dealer charge, not a government fee. Some states cap it. Where it isn't capped, dealers usually charge everyone the same, so negotiate the car's price down by that amount.

Estimates, not financial advice. Taxes, insurance, PMI and fees vary by lender, county and city; confirm with your lender, dealer and state agency before acting.
