Car Loan Calculator

Buying a car with a loan is really buying two things: the car, and the cost of borrowing the money. This free car loan calculator shows your monthly payment, the total interest you will pay, and the total cost, so you can compare cars, down payments and loan terms before you sign anything.

How a car loan payment works

When you take a car loan, the lender lends you the price minus your down payment. You then repay that amount in equal monthly payments. Each payment covers the interest charged for that month first, and the rest reduces what you still owe. That is why early payments feel mostly like interest, while later payments reduce the balance faster.

The three numbers that matter most are the amount financed, the interest rate, and the term. A lower amount, a lower rate, or a shorter term usually means less total interest, even if the monthly payment looks higher.

The formula, in plain English

Monthly payment = loan amount × monthly interest rate × (1 + monthly interest rate) raised to the number of months, divided by that same figure minus 1. You do not need to work this out by hand: the calculator above does it for you. If the interest rate is 0%, the monthly payment is simply the loan amount divided by the number of months.

Worked example

Try the pre-filled example: a $25,000 car, a $5,000 down payment, a 6.5% annual interest rate, and a 60-month term. The amount financed is $20,000. The calculator shows a monthly payment of about $391.32, total interest of about $3,479, and a total cost of about $28,479 including the down payment. Change the term to 48 months and watch the monthly payment rise, while the total interest falls. That trade-off is the heart of choosing a car loan.

Tips to pay less total interest

• Make a bigger down payment. You borrow less, so you pay interest on less money.
• Choose the shortest term you can comfortably afford. A longer term lowers the monthly payment but usually raises total interest a lot.
• Improve your credit before you apply, if you have time. Even a slightly lower rate can save hundreds over the life of the loan.
• Compare the total cost, not just the monthly payment. A low monthly payment can hide a long term and high interest.
• Consider part-prepayment. Extra payments usually reduce the balance, but check first whether your lender charges a prepayment fee.

Common mistakes to avoid

• Only looking at the monthly payment and ignoring the term and interest rate.
• Rolling an old car loan balance into a new loan without checking the new total cost.
• Adding expensive extras to the loan, so you pay interest on them for years.
• Skipping the fine print on fees, late charges and prepayment rules.
• Buying more car than your budget can handle, even if the lender approves it.

Frequently asked questions

What is the difference between the loan amount and the car price?

The car price is what the car costs. The loan amount, or amount financed, is the car price minus your down payment, plus any fees or extras you choose to finance.

Is a longer loan term better?

It lowers the monthly payment, which can help cash flow, but it usually increases total interest and the risk of owing more than the car is worth. Choose the shortest term with a payment you can afford comfortably.

Does this calculator include taxes and fees?

No. It estimates the loan payment only. Taxes, registration, dealer fees and insurance are extra, so add them to your budget separately.

Can I pay the loan off early?

Usually yes, but some lenders charge a prepayment or foreclosure fee. Ask before you sign, and check whether extra payments reduce the balance or are held as advance payments.

What if my credit score is low?

You may still get a loan, but often at a higher rate. A larger down payment, a cheaper car, or a co-applicant with stronger credit may help. Avoid any lender that asks for a large fee upfront before approving you.
