Frequently asked questions
How is the car payment calculated?
First we compute the amount financed: vehicle price minus down payment and trade-in, plus any tax/fees you include. That principal is then amortized at your APR over the term using the standard fixed-rate formula M = P × r(1+r)ⁿ / ((1+r)ⁿ − 1), where r is the monthly rate and n is months. At 0% APR the payment is simply principal ÷ months.
How do down payment and trade-in affect the loan?
Both reduce the amount you finance dollar-for-dollar. A larger down payment or trade-in lowers the principal, which lowers the monthly payment and total interest. If down payment plus trade-in cover the full price (and fees), there is nothing left to finance.
Does this include tax/title/fees?
Only if you enter them in the optional fees field. Many dealers roll tax, title, documentation, and similar costs into the loan; add those here so the amount financed reflects them. If you leave fees blank, they are treated as zero — fold them into the vehicle price instead if you prefer.
Is this a loan offer?
No — estimate for planning only. Results are mathematical projections for a fixed rate and term. They are not a credit decision, approval, or quote from a lender. Real offers depend on credit, lender fees, insurance, and local tax rules.
