How Extra Payments Accelerate Amortization
Car loans use simple interest amortization where the monthly payment ($M$) is determined by:
$$M = P \cdot \frac{r(1+r)^n}{(1+r)^n - 1}$$
- Principal Only: Ensure your lender specifies that extra funds are applied directly to the principal balance rather than prepaying future interest or monthly due dates.
- Avoid Prepayment Penalties: Most consumer auto loans in the US and UK have zero prepayment penalties under federal consumer protection laws.
