How these calculators work
Auto calculators bring the full picture of car ownership into one place. Estimate loan payments and payoff dates, weigh refinancing, forecast how quickly a new car depreciates, budget for fuel costs, and find the price range that fits your income. Know the total cost before you drive off the lot. Every calculator in this category publishes its formula, worked example and assumptions so you can verify the math yourself.
Frequently asked questions
How much car can I afford?
A common rule keeps car payments within 10-15% of monthly take-home pay and total car debt within about 20% of income. The Car Affordability Calculator estimates a realistic purchase price from your income, debts and down payment.
How fast does a new car depreciate?
New cars typically lose 15-20% of value in the first year and about 60% over five years. Depreciation is your biggest hidden ownership cost and is a major reason used cars are cheaper to own.
Should I refinance my auto loan?
Refinancing helps if you can get a lower rate without lengthening the term too much, and if you plan to keep the car beyond the payoff point. Compare total interest before and after to decide.
