Money borrowed to purchase a vehicle with agreement to repay with interest over time.
\(PMT = \frac{(VP - TI - DP) \times r \times (1+r)^n}{(1+r)^n-1}\)
Where PMT=monthly payment, VP=vehicle price, TI=trade-in, DP=down payment, r=monthly rate, n=payments.
Early payments are mostly interest, later payments are mostly principal.
Q: How do extra payments save money?
A: Extra payments reduce principal immediately, lowering interest on future payments. $100 extra monthly saves ~$3,200 on 5-year loan.
Q: 48 vs 60-month loan?
A: 48-month: $629/month, $1,142 interest. 60-month: $566/month, $3,968 interest. Higher monthly but less total interest.
