The amount financed is the vehicle price minus your deposit, positive part-exchange contribution, and any dealer or manufacturer contribution. The calculator converts APR to a matching effective monthly rate. Unlike standard HP, it does not subtract the optional final payment as though that amount were paid upfront. Instead, the future final payment is discounted through the agreement and the remaining present value is amortised across the regular monthly payments.
The agreement duration includes the final-payment month. For example, 48 regular payments followed by a balloon is represented as a 49-month agreement. The schedule contains the regular payments first and the optional final payment as the last row. Penny rounding is reconciled in the final regular payment so the entered balloon remains unchanged.
If you enter a first payment date, due dates advance by calendar month from that anchor. Payments before today are treated as passed; a payment due today remains upcoming. The estimated amount paid by you so far is your upfront contribution plus regular payments scheduled before today. Dealer or manufacturer contribution is shown separately so it is not mistaken for money you personally paid. The estimated finance balance comes from this illustrative schedule, while remaining to own is the sum of remaining regular scheduled payments, the optional final payment, and any separate purchase fee. These schedule-based figures do not confirm collection of each payment and are not an early-settlement quote.
