Why the contract deserves a careful read

A car loan agreement is a legally binding document. Once you sign, the terms are fixed. Dealers and lenders sometimes present contracts under time pressure, which can push buyers to skim rather than read. Taking 20 to 45 minutes to work through the document can prevent costly surprises over a loan that may last four to seven years.

This checklist covers the items most worth verifying before you commit. For a broader understanding of how loan interest and terms work together, see our guide to auto loan interest rates and terms. If you are buying for the first time, our first-time buyer overview covers the full financing and ownership picture.

Required

Loan amortization calculator

Lets you verify the monthly payment and total interest figures against what is printed in the contract.

Required

Calculator or spreadsheet

Useful for cross-checking that the amount financed, APR, term, and monthly payment are internally consistent.

Optional

Your auto insurance declarations page

Helps you check whether GAP coverage is already included before accepting a dealer-sold GAP policy.

Required

Pen and notepad

For noting questions, flagging clauses you want explained, and recording agreed terms before you reach the signing stage.

Core loan terms to verify

These numbers define the financial obligation you are accepting. Confirm each one matches what was discussed verbally before you reached the signing table.

Loan figures

Confirm the APR (Annual Percentage Rate) matches the rate you were quoted, including any fees folded into the cost of credit. Must
Check the total amount financed, which should equal the vehicle price minus your down payment, plus any rolled-in fees. Must
Verify the monthly payment amount and confirm it matches your budget calculation. Must
Note the total of all payments over the life of the loan so you know the full cost of borrowing. Must
Confirm the loan term in months matches what was agreed, since a longer term lowers monthly payments but increases total interest paid. Must

Fees and charges

Identify every fee listed in the contract, including documentation fees, origination fees, and dealer processing charges. Must
Ask for an explanation of any fee you do not recognise before signing. Must
Check whether a prepayment penalty clause exists, which would charge you for paying the loan off early. Must
Confirm whether there is a late payment fee and note the grace period, if any. Should

Add-on products

Identify every add-on product listed, such as GAP insurance, credit life insurance, paint protection, or a service contract. Must
Confirm which add-ons are optional and request removal of any you did not agree to purchase. Must
Ask for the cost of each add-on as a standalone figure so you can assess it separately. Should
Check whether GAP coverage is already provided by your auto insurer before accepting a dealer-sold policy. Should
Review service contract terms to understand what is excluded, since exclusions often define the real value of the product. Nice to have

Contract accuracy and completeness

Confirm that your name, address, and personal details are spelled correctly throughout the document. Must
Verify the vehicle identification number (VIN), make, model, year, and trim level match the car you are purchasing. Must
Check that no fields are left blank: draw a line through any blank space before signing. Must
Request a complete copy of the signed contract before leaving the dealership. Must
Confirm the lender name and contact information are present in the contract. Should

Trade-in and down payment

Verify the trade-in value credited matches the agreed figure from your negotiation. Must
Confirm the down payment amount recorded in the contract matches what you are actually paying. Must
Check whether any negative equity from a trade-in has been rolled into the new loan and understand how that increases the amount financed. Should

Watch for rate markups from the dealer

Dealers sometimes add a markup to the interest rate offered by the lender, known as a dealer reserve. The contract may show a higher APR than the lender's base rate. If you received a pre-approval from a bank or credit union before visiting the dealership, compare that rate directly against the contract APR. A difference of even half a percentage point can add hundreds of dollars to the total cost of the loan.

Add-on products and fees

Finance offices at dealerships often present add-on products as part of the standard package. Most are optional. Some are worth considering; others add cost with limited benefit for your situation. Our article on extended warranties and vehicle service contracts explains what these products actually cover and what questions to ask.

Never sign a contract with blank fields

A blank field in a signed contract can legally be filled in after the fact. Before signing any page, draw a clear line through every unused space. If the finance office is reluctant to allow this, that warrants serious caution. Take your time: no legitimate lender or dealer should pressure you to sign without reading.
