Auto Loan Calculator — Monthly Car Payment Calculator

Calculate your exact monthly car payment and total interest for any vehicle price, rate, and term. See why getting pre-approved before the dealership saves real money.

Quick answer: An auto loan payment depends on vehicle price, down payment, trade-in, APR, fees, and term. Longer terms lower the payment but usually increase total interest and negative-equity risk.

Frequently Asked Questions

Everything you need to know.

What is a good auto loan rate in 2026?
Excellent credit (720+): 5–7%. Good credit (680–720): 7–10%. Fair credit (620–680): 10–15%. Credit unions typically beat banks and dealers by 1–2%. Getting pre-approved from a credit union before visiting a dealership gives you negotiating leverage.
How long should an auto loan be?
Keep your loan term no longer than 60 months (5 years). 84-month loans reduce payments but cost significantly more in interest and create negative equity risk — you can owe more than the car is worth for years. A good rule: if you cannot afford the payment on a 60-month loan, you cannot afford the car.
Is the Auto Loan Calculator — Monthly Car Payment Calculator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Auto Loan Calculator — Monthly Car Payment Calculator affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to compare auto loan rates ->, or run Money Map to compare this loans & credit decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (auto) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Dealerships make more profit on financing than on the car itself. A 7% dealer rate vs 5% credit union rate on a $35,000 vehicle over 60 months costs $1,900 extra. Always get pre-approved before the dealership.

How to Use It

  1. 1Enter vehicle price and down payment
  2. 2Enter the loan APR
  3. 3Set the loan term (36–84 months)
  4. 4Compare total cost at different terms — longer terms mean more total interest
