Calculating…
Step 1
Start with the quote
Use the written quote. A disclosed APR may include certain fees.
Choose the option that matches the written quote; these are model inputs, not market recommendations.
Step 2
Build the out-the-door price
Ask the current lender for the payoff amount; it can differ from a statement balance.
Manual estimate only. Confirm the local taxable base.
Itemized financed fees
Leave an item at zero when it is not in the written deal.
Only include products you intend to finance.
Optional
Test extra principal
Only include this when the contract applies extra payments to principal without penalty.

How to use this Auto Loan Calculator
Copy the vehicle price and financing terms from a written quote. Add the rebate, cash down, trade allowance and payoff, tax treatment, and each financed fee separately. Then compare offers while keeping the purchase inputs consistent.
How the auto loan estimate works
The amount financed starts with the purchase worksheet, then the fixed-rate amortization engine applies the annual interest-rate input across the selected number of monthly payments. It does not infer a lender rate, approval, insurance cost, or jurisdiction-specific tax rule.
Before you compare offers
Ask for an itemized cash out-the-door price before discussing the monthly payment. Compare total interest and total payments on the same purchase inputs, and confirm whether extra payments are applied to principal.
