Frequently Asked Questions (FAQ)
What is loan amortization?
Amortization is the process of spreading out a loan into a series of equal periodic payments that cover both principal and accumulated interest over time.
How does changing the loan term affect overall costs?
Longer repayment terms reduce your monthly installment amount but significantly increase total interest paid over the life of the loan.
What is APR vs. Interest Rate?
The interest rate is the base cost of borrowing, whereas APR (Annual Percentage Rate) includes additional lender fees and origination expenses for a true comparison.
Can extra payments reduce overall loan interest?
Yes, making extra payments directly towards the principal balance shortens loan duration and reduces total interest charges accrued.
What factors influence loan interest rates?
Credit scores, debt-to-income ratios, loan term lengths, market benchmark rates, and collateral availability affect lender pricing.
