Shorter Is Cheaper

A 36-month loan costs significantly less in interest than 72 months, even at the same rate. The payment is higher but the total cost is lower.

Credit Score Matters

A 750+ credit score can get you rates 3–5% lower than a 620 score — which can mean thousands saved on a typical car loan.

Estimates do not include taxes, registration fees, dealer fees, or gap insurance. Actual loan terms depend on your lender and credit profile.

Car Loan Calculator — Common Questions

How is a car loan monthly payment calculated?

Your monthly car payment depends on the loan amount (vehicle price minus down payment and trade-in), interest rate, and loan term. The longer the term, the lower the monthly payment — but the more total interest you pay. A $30,000 loan at 7% over 60 months costs about $594/month. Extending to 72 months drops the payment to $511/month but adds over $700 in additional interest.

What is a good interest rate for a car loan?

As of 2025, good credit (720+) typically qualifies for rates around 5–7% for new vehicles and 7–9% for used. Excellent credit (760+) can get below 5% from credit unions or manufacturer financing. Rates above 15% are considered high — if you're being offered that, consider building credit before buying or making a larger down payment. Always shop rates from your bank, credit union, and dealership.

How much should I put down on a car?

Financial advisors typically recommend 20% down on a new car and 10% on a used car. This prevents being 'underwater' (owing more than the car is worth) as vehicles depreciate quickly — new cars lose 15–25% of value in the first year. A larger down payment also reduces your monthly payment and total interest paid. At minimum, put enough down to cover first-year depreciation.

Should I take a 60-month or 72-month car loan?

Shorter terms mean higher payments but less interest paid — a 60-month loan is almost always better financially than a 72 or 84-month loan. Extended terms put you at higher risk of being upside-down on the loan (owing more than the car is worth). Only consider a longer term if the monthly payment at 60 months is genuinely unaffordable. If a car requires 84 months to be affordable, the car is probably too expensive.

What is the 20/4/10 rule for buying a car?

The 20/4/10 rule is a popular car buying guideline: put at least 20% down, finance for no more than 4 years, and keep total vehicle expenses (payment + insurance) under 10% of your gross monthly income. It's a conservative rule — many people go beyond it — but it keeps you from being financially strained by a depreciating asset. Adjust based on your income stability and other financial obligations.

Is it better to pay cash or finance a car?

If you can get a 0% or very low interest rate through manufacturer financing, financing can make sense even if you have the cash — your money earns more in investments. If the interest rate is above 4–5%, paying cash is usually better because guaranteed return on avoiding interest beats uncertain investment returns. Always compare the true cost of financing vs. the opportunity cost of spending savings.
