Car Buying & Auto Loan Calculators
Financing decisions make a car thousands cheaper or more expensive without changing the car at all. These tools show the payment, the total interest, the lease-versus-buy math, and the price range that genuinely fits your income.
Estimate your monthly car payment and total interest from price, trade-in, down payment, sales tax, APR and term, with a full amortization schedule.
Open calculatorWork backward from your income to the car price you can afford, using a sensible payment-to-income rule plus down payment, APR and term.
Open calculatorSee whether refinancing your car loan saves money. Compare your current loan with a new rate and term for the monthly and lifetime-interest savings.
Open calculatorCompare leasing and buying the same car over the same years. See the total cost of each and why you pay for depreciation either way.
Open calculatorDecide whether to keep your current car or trade it in. Compare the cost of keeping it running against the cost of upgrading over the next few years.
Open calculatorShop the total cost, not the monthly payment
Dealers negotiate around the monthly payment because it is the easiest number to shrink — stretch the term far enough and almost any car fits almost any budget. The number that matters is the total you pay: the price of the car plus every dollar of interest to borrow for it. A low payment on a long loan can cost thousands more than a higher payment on a short one.
Two figures drive that total: the APR — the real yearly cost of the loan including fees — and the term. Run the loan calculator with the actual APR your bank or credit union quotes, not the advertised teaser rate, to see the payment and the total interest side by side before you sign.
Longer terms hide a bigger bill
Six- and seven-year car loans are common now because they push the payment down, but they carry two hidden costs. You pay interest for far longer, and for much of the loan you owe more than the car is worth — being underwater. Sell or total the car in that window and you still owe the gap.
A shorter term raises the payment but shrinks total interest and gets you to positive equity faster. If the shorter term is a stretch, that is usually a sign the car is more than you should finance — the affordability calculator works backward from a comfortable payment to a price range that fits your income.
