What this scenario helps you see
A high interest assumption and long term work together to slow early principal reduction. Open the amortization schedule to see how much of the first payments goes to interest and how much balance would remain if you sold in three years.
Refinancing later is uncertain. Future eligibility, rates, vehicle age, loan-to-value limits, and fees can affect whether it is available or useful. Assess the original contract on terms you can carry rather than assuming a future refinance will fix it.
An extra monthly payment can reduce interest in this model, but only if the lender applies it to principal as assumed. Compare that strategy with borrowing less at the outset and preserving the reserves needed for running costs.

Method and limitations
The model uses fixed monthly amortization: M = P × r ÷ (1 − (1 + r)^−n), with principal P, monthly rate r, and n payments. At zero interest, payment is P ÷ n. Interest and payments are rounded monthly, and the last payment reconciles the balance. See the complete loan methodology for assumptions and sources.
Daily-interest contracts, prepaid finance charges, late payments, and lender rules can produce a different result. This page is an educational example, not a rate quote or approval. CFPB explains loan terminology and disclosures.
Questions about this example
Is a 72-month term automatically a bad choice?
This tool does not make that judgment for every household. It shows the higher interest and longer balance exposure under the entered assumptions so the tradeoff is explicit.
Can I rely on refinancing this later?
No. Future rates, eligibility, fees, and vehicle requirements are uncertain. Evaluate whether the original contract is sustainable on its own.
What if I sell the car after three years?
Use the balance at month 36 and compare it with a cautious resale estimate. A sale below payoff leaves a shortfall that still has to be settled.
Does 12% describe my credit eligibility?
No. No credit information is collected and no lender evaluates this scenario. It is an illustrative rate for testing sensitivity.
