Finance calculations are estimates based on the values and assumptions you enter. They are not financial, tax, lending or investment advice. Verify the terms, rates, fees and local rules that apply to your situation.
About this tool
Auto Loan Calculator
Estimate vehicle financing after considering price, down payment, net trade-in value, incentives, user-supplied sales tax and fees. Review amount financed, payment and total interest for different vehicle-financing scenarios.
What This Auto Loan Calculator Does
Estimate vehicle financing costs after considering price, down payment, trade-in, incentives, tax and fees.
Inputs and What They Mean
Enter the vehicle price, down payment, trade-in value and any amount still owed on the trade-in. Add incentives, sales tax, fees, interest rate and loan term. You can choose whether tax and fees are included in the financed balance.
How the Calculation Works
The calculator first estimates the amount that must be financed. A trade-in with an outstanding balance contributes only its net equity, while incentives reduce the effective amount financed. If tax and fees are financed, they are added before the loan payment is calculated.
How to Use the Calculator
- Enter the values that describe your situation.
- Check the units, frequency and assumptions shown beside each field.
- Choose any available mode or calculation target before calculating.
- Select Calculate and review the result card.
- Change one assumption at a time when comparing scenarios.
How to Interpret the Result
Compare both the financed amount and the resulting payment. A lower payment can result from a longer term, but the longer term can increase total interest. A larger down payment or positive trade-in equity can reduce the amount financed.
Important Assumptions and Limitations
Vehicle taxes, registration charges and dealer fees differ widely by country and state/province. Tervilo keeps the calculation input-driven rather than embedding one jurisdiction's tax table.
Practical Planning Tip
Use the calculator as a scenario-testing tool. Save or compare a conservative case, a base case and a more optimistic case instead of relying on a single projection. For financial decisions, verify rates, fees, taxes, contractual terms and local rules with the relevant provider or official source.
