Purchasing a new or pre-owned vehicle is one of the largest financial commitments most households make. Dealership quotes often obscure the true cost of financing by blending sticker prices, trade-in allowances, documentation fees, state sales taxes, and manufacturer cash rebates into a single confusing monthly payment. This comprehensive auto loan calculator empowers car buyers to take control of dealership negotiations with transparent, cent-exact math. Input vehicle purchase prices, trade-in values (including existing lien balances), loan durations from 24 to 84 months, and dealer documentation fees to uncover exact monthly obligations and cumulative interest charges. You can also evaluate whether dealer promotional low APR financing saves more money than bank loans coupled with factory cash rebates.

Frequently asked questions about Auto Loan Calculator
How does a trade-in vehicle reduce the sales tax on a new car?
In many jurisdictions, vehicle sales tax is assessed only on the difference between the purchase price and the trade-in allowance. For example, buying a $30,000 vehicle with a $5,000 positive trade-in results in sales tax calculated only on the remaining $25,000.
What happens if I owe more on my trade-in than it is worth?
When you owe more than your trade-in's market value, you have 'negative equity' or are 'underwater'. Enter the full trade-in value and the amount owed; the calculator automatically rolls the negative balance into your new loan amount.
Which is better: low dealer APR or a cash rebate with bank financing?
Use the built-in Financing Comparison tool to find out. Generally, for shorter loans or smaller loan amounts, taking the upfront cash rebate saves more money, while for larger balances over 60 to 72 months, ultra-low APRs often result in greater total savings.
Should I roll taxes and dealer fees into my auto loan?
Paying sales tax, registration, and dealer fees upfront out of pocket keeps your borrowed principal lower and prevents you from paying interest on government taxes over 5 or 6 years.
