❓ Frequently Asked Questions
How is a monthly loan payment calculated?
+
Monthly loan payments are calculated using: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is monthly interest rate, and n is total number of payments. For example, a $30,000 auto loan at 5% for 60 months results in a $564.51 monthly payment. This formula ensures equal payments that cover both principal and interest.
What is the difference between a 48-month and 72-month auto loan?
+
A 48-month loan has higher monthly payments but lower total interest. A 72-month loan has lower monthly payments but higher total interest. For $30,000 at 5%: 48-month is $690/month with $3,141 total interest; 72-month is $553/month with $8,000 total interest. Choose based on your budget and how much interest you're willing to pay.
How does interest rate affect my total loan cost?
+
Interest rate has a massive impact. A $30,000 loan at 3% costs $1,646 in total interest, but at 8% costs $4,597. That's nearly $3,000 difference! Your rate depends on credit score, income, and lender. Even a 1% difference saves thousands. Shop around with multiple lenders to get the best rate.
What is an amortization schedule?
+
An amortization schedule is a month-by-month breakdown of your loan payments. Early payments are mostly interest; later payments are mostly principal. For example, your first $564 payment might be $125 principal and $439 interest. This gradually reverses as you pay down the principal. This schedule helps you understand where your money goes.
What happens if I make extra principal payments?
+
Extra principal payments significantly reduce total interest and shorten your loan term. Making one extra payment per year on a $30,000 loan at 5% for 60 months saves $857 and pays off the loan 5 months early. Always specify extra payments go to principal, not toward the next payment, to maximize savings.
