Frequently Asked Questions
How is the monthly car payment calculated?
The tool uses the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is the loan principal (including tax and fees), r is the monthly interest rate, and n is the total number of payments.
What does Total Cost of Vehicle include?
It includes the down payment, trade-in credit, all monthly payments over the full term, sales tax, and registration fees — the complete out-of-pocket cost of the vehicle.
Is my data sent to a server?
No. All calculations run locally in your browser. Your financial information is never uploaded or stored anywhere.
Can I compare different loan terms?
Yes. Change the Loan Term dropdown and all results — monthly payment, total interest, and the amortization schedule — update instantly.
