Auto Loan Calculator
The sample amount and rate below are placeholders, not market averages — replace them with the price and rate on your lender’s offer. A shorter term and a larger down payment reduce interest, and cars lose value quickly, so avoid owing more than the car is worth.
Auto Loan calculator
Move the sliders or type your own numbers. Sample amounts and rates are placeholders — enter the figures from your lender’s Loan Estimate or offer.
📊 Principal and interest by year
Early payments are mostly interest; the principal share grows every year. Hover or tap a bar for details.
📅 Amortization schedule
Year-by-year summary — tap “+” to see every month. Download the full monthly schedule as a spreadsheet.
⚡ Extra payments — how much can you save?
Test a one-time extra payment, a fixed extra amount each month, or a yearly lump sum. Extra principal payments cut the balance that interest is charged on, so earlier ones save the most.
🔄 Refinance break-even
Enter a new rate, term and closing costs to see the new payment and how many months it takes to recover the costs.
⚖️ Compare loan offers side by side
Enter up to three offers. The best deal has the lowest total cost (interest plus fees), not necessarily the lowest rate or payment.
🏡 Affordability — how much can you borrow?
Lenders compare your monthly debt payments to your gross monthly income (debt-to-income, or DTI). This shows the payment your income supports at the DTI you choose.

| Topic | Details |
|---|---|
| What sets your rate | Credit score, loan term, down payment, vehicle age and lender |
| Total cost | Interest plus any fees you finance; compare APR, not only the monthly payment |
| Negative equity | Rolling an old loan balance into a new loan raises what you owe relative to the car’s value |
| Credit unions | Often worth quoting alongside banks and dealer financing |
Tips to lower your auto loan cost
- Get a pre-approval before visiting the dealer so you can compare the dealer’s financing to a firm offer.
- Compare total interest across terms; a longer term lowers the payment but usually raises the total cost.
- Include insurance, fuel and maintenance when deciding what payment fits your budget.
- Decline add-ons you did not ask for, or price them separately.
📝 Documents you need and how to apply for a auto loan
- Verifiable income and a debt load the lender considers manageable
- A credit history the lender can review; rates depend heavily on it
- Proof of auto insurance on the vehicle
- A vehicle that meets the lender’s age and mileage rules
- Driver’s license and Social Security number
- Proof of income such as recent pay stubs or tax returns
- Proof of residence such as a utility bill
- Vehicle details: VIN, mileage and the purchase agreement or buyer’s order
- Proof of insurance
- Trade-in title or payoff information, if applicable
How to apply, step by step
- Set a total budget that includes insurance, fuel and maintenance.
- Get pre-approved by a bank or credit union so you know your rate and limit.
- Compare the dealer’s financing offer with your pre-approval.
- Negotiate the price of the car first, then the financing.
- Read the contract for the APR, term, fees and add-ons before you sign.
- Arrange insurance and complete title and registration.
Pre-approvals are often quick; dealer financing can be completed at signing. Every lender sets its own requirements, so confirm the list with the lender before you apply.

Loan calculator FAQs
Is dealer financing more expensive?
Not always — compare the APR and total cost of the dealer offer against a bank or credit union pre-approval.
Is a longer loan term a good idea?
It lowers the monthly payment but increases interest and the time you may owe more than the car is worth.
What is amortization?
Amortization is paying off a loan with fixed payments over time. Each payment covers that month’s interest and reduces the principal; over time a larger share goes to principal.
Is the result exactly what my lender will charge?
It is a close estimate. Lenders may calculate interest daily, use a different first-payment date or round differently. Your loan documents and repayment schedule are final.
What is APR?
The annual percentage rate expresses the yearly cost of a loan, including interest and certain fees. Lenders must show it in their Truth in Lending disclosures.
Should I make extra payments?
Extra payments toward principal reduce total interest and can shorten the loan. Check that there is no prepayment penalty and that extra money is applied to principal.
What happens if I miss a payment?
You may owe a late fee, and lenders can report late payments to the credit bureaus, which can lower your credit score. Contact your lender early if you expect trouble paying.
