Understanding Loan Amortization
All standard loans use amortization — a repayment schedule where each payment covers interest on the remaining balance plus a portion of principal. Early payments are mostly interest; as the balance decreases, more of each payment goes toward principal. Our calculator generates the complete schedule so you can see exactly where every dollar goes.
How to Reduce Loan Interest Costs
Three strategies dramatically reduce total interest: shop for lower rates (even 1% difference on a $30,000 loan saves over $1,600 over 5 years); choose a shorter term (36 vs 60 months costs more monthly but saves significantly in interest); and make extra principal payments whenever possible — even $50/month extra on a 5-year loan saves hundreds in interest.
