quickly. This glossary defines the most important terms in simple language.
The terms to know first
The most important auto loan terms are APR, interest rate, amount financed, loan
term, monthly payment, down payment, loan-to-value ratio, total of payments, and
finance charge. Understanding these terms can help you compare loan options beyond
the monthly payment.

Frequently asked questions
What is the most important auto loan term?
APR is one of the most important comparison terms because it reflects a broader yearly cost of credit. But you should also compare loan term, amount financed, monthly payment, and total of payments.
Is APR the same as interest rate?
No. The interest rate is the rate charged on the amount borrowed. APR includes the interest rate and certain fees, making it a broader cost measure.
What does amount financed mean?
Amount financed is the amount of credit provided after factoring in down payment, trade-in, taxes, fees, and other financed items.
What does LTV mean?
LTV means loan-to-value ratio. It compares the loan amount with the vehicle's value and helps lenders evaluate risk.
What does final approval mean?
Final approval usually means the lender has verified required information and is ready to fund or complete the loan subject to the signed agreement and any remaining conditions.
