What this scenario helps you see
A high rate and a long term slow down early principal reduction together. Open the amortization schedule to see how much of the first payments goes to interest, and how much you'd still owe if you sold in three years.
Refinancing later is a maybe, not a plan. Future rates, eligibility, vehicle age, loan-to-value limits and fees all decide whether it's possible or worthwhile. Judge the original contract on terms you can carry rather than hoping a refinance will fix it.
An extra monthly payment cuts interest in this model only if the lender applies it to principal. Compare that approach with borrowing less to begin with, and keep enough reserves for running costs.

| Annual interest | Monthly payment | Total interest |
|---|---|---|
| 10% | $463.15 | $8,346.36 |

| 14% | $515.14 | $12,090.45 |
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.

Questions about this example
Is a 72-month car loan automatically a bad choice?
Not for every household. This page shows the higher interest and longer balance exposure under the numbers you enter, so you can judge the trade yourself.
Can I count on refinancing a 72-month loan later?
No. Future rates, eligibility, fees and vehicle requirements are uncertain, so make sure the original contract works on its own.
What if I sell the car after three years on this loan?
Look up the balance at month 36 and compare it with a cautious resale estimate. If the car sells for less than you owe, you still have to cover the difference.
Does a 12% rate describe my credit?
No. This page collects no credit information, and no lender has evaluated it. Twelve percent is simply an illustrative rate for testing how sensitive the payment is.
