Key Takeaways

  • Lease agreements contain lease-specific terms such as money factor and residual value that directly affect your monthly payment.
  • Loan agreements may include prepayment penalties that make early payoff more expensive than expected.
  • Both contract types can include add-on products that inflate costs without being clearly flagged.
  • Mileage caps on leases carry per-mile overage fees that add up quickly on longer commutes.
  • Reviewing the contract before signing, not during, gives you time to ask questions or walk away.

Why reviewing the contract matters before you sign

A vehicle contract is a multi-page legal document. The payment amount you agreed on verbally may be accurate, but other terms buried in the paperwork can add thousands of dollars to the total cost over the life of the agreement. Both lease and loan contracts regularly include add-on products, fees, and clauses that were never discussed at the negotiating table.

The financial structure of leasing versus buying differs substantially, and so do the contract terms that matter most for each. This checklist separates them so you know exactly what to look for depending on which path you are taking.

Before you sit down with a contract, gather the tools listed below. Having a calculator and your insurance declarations page on hand lets you verify numbers in real time rather than guessing.

Required

Calculator (basic or smartphone)

Convert the money factor to an APR, verify total loan cost, and check overage fee estimates.

Required

Your state's DMV fee schedule

Cross-check registration and title fees listed in the contract against published government rates.

Optional

Vehicle history report

Confirm the VIN in the contract matches the actual vehicle and review any ownership or damage history.

Required

Your insurance declarations page

Confirm your current policy meets the minimum coverage requirements stated in the contract.

How to work through the checklist

Print or download the contract if the dealership allows it, and read it away from the sales floor if possible. Work through each group below in order. Mark any line item that does not match your records of the negotiation and ask for a written explanation before proceeding.

Do not sign under time pressure

Dealers may suggest that a deal will expire if you do not sign immediately. A legitimate contract can be reviewed at your own pace. If you feel rushed, ask to take the contract home or step away to read it without interruption. Signing before you fully understand the terms can lock you into costs that are difficult or impossible to reverse.

Verbal promises are not binding

If a dealer or finance officer tells you something verbally that is not in the written contract, it generally has no legal force. Any agreed terms, waived fees, or included products must appear in the written document. Do not rely on a handshake or a spoken assurance.

The checklist is organized into four groups: lease-specific terms, loan-specific terms, add-on products, and fees and final numbers. If you are signing a lease, focus on the first, third, and fourth groups. If you are taking a loan, focus on the second, third, and fourth groups.

Lease-specific terms

Locate the money factor and convert it to an approximate APR by multiplying by 2,400. Confirm this rate is consistent with what the dealer quoted verbally. Must
Verify the residual value (the vehicle's projected worth at lease end) listed in the contract matches what was discussed, since a lower residual increases your monthly payment. Must
Find the capitalized cost (the negotiated price of the vehicle) and any capitalized cost reductions (down payment equivalents). Confirm these numbers match your negotiations. Must
Read the mileage allowance and per-mile overage charge. Calculate whether your typical annual driving fits within the cap without accruing fees. Must
Check the wear-and-tear standards section. Understand what the leasing company defines as normal versus excessive wear, since charges at turn-in can be substantial. Should
Review the early termination clause and calculate the estimated penalty. Confirm you understand what it would cost to exit the lease if your circumstances change. Must

Loan-specific terms

Confirm the annual percentage rate (APR) printed in the contract matches the rate the lender quoted. Even a fraction of a percent difference composes into hundreds of dollars over the loan term. Must
Check the loan term in months. Longer terms lower the monthly payment but increase total interest paid. Must
Search the contract for a prepayment penalty clause. If one exists, understand the cost before planning to pay off the loan early. Must
Verify the total amount financed. This should equal the vehicle price plus any fees rolled into the loan, minus your down payment. Must
Review whether interest is simple or precomputed. Simple interest accrues on the remaining balance; precomputed interest is calculated upfront, which can reduce the benefit of early payoff. Should

Add-ons and bundled products

Scan the itemized breakdown for any products you did not explicitly agree to, such as paint protection, tire-and-wheel coverage, or vehicle theft systems. Must
Identify whether GAP insurance is included in the contract and whether you actually need it. GAP coverage pays the difference between what you owe and what the vehicle is worth if it is totaled. It is not always necessary. Should
Check for extended warranties or service contracts. Confirm the term, coverage limits, and deductible, and weigh whether the cost matches the benefit. Should

Fees, taxes, and final numbers

Review the acquisition or origination fee on a lease, or the loan origination fee on a purchase loan. These are legitimate but vary and may be negotiable. Must
Confirm sales tax, registration, and title fees are accurately reflected. Cross-reference with your state DMV's published fee schedule if possible. Should
Compare the total cost over the full term (all payments plus fees plus any balloon or residual payment) against what you calculated independently before arriving at the dealership. Must
Verify that any rebates, manufacturer incentives, or trade-in credits are applied correctly and have not been absorbed elsewhere in the deal structure. Must

For a broader look at what these contract items cost over time, the hidden vehicle costs families often miss article covers registration, gap insurance, and other budget items that surface after signing.

After you finish the review

If every line in the contract matches your notes from negotiation and you understand each charge, you are in a solid position to sign. If any item is unclear or inconsistent, request a corrected contract in writing before proceeding. Dealers can reprint documents; the inconvenience of waiting is minor compared to the cost of a multi-year error.

This is general financial information, not legal advice

Contract terms vary by lender, state, and deal structure. This checklist covers common items to review, but it does not replace the guidance of a qualified attorney or financial adviser familiar with your specific situation. If a contract contains terms you do not understand, consult a licensed professional before signing.

Once you have a vehicle, routine vehicle maintenance and trip preparation are the next practical steps for keeping costs predictable. And if you are still weighing whether to finance or pay cash, the trade-offs between financing and a cash purchase are worth working through before you return to the dealership.
