Frequently Asked Questions
What is loan amortization?▼
Loan amortization is the process of spreading out a loan into a series of fixed payments over time. Each payment covers both interest and principal. In the early years, a larger portion of each payment goes toward interest, while in later years, more goes toward principal. An amortization schedule shows this breakdown for every payment.
How do extra payments reduce my loan cost?▼
Extra payments go directly toward reducing your principal balance. Since interest is calculated on the remaining balance, a lower balance means less interest accrues each month. This creates a compounding effect: you pay less interest, more of each regular payment goes to principal, and the loan is paid off faster. Even small extra payments can save thousands in interest.
Why is more interest paid at the beginning of a loan?▼
Interest is calculated as a percentage of the outstanding balance. At the start of a loan, the balance is at its highest, so the interest portion of each payment is largest. As you pay down the principal over time, the balance decreases, so less interest accrues and more of each payment goes toward principal. This is called front-loaded interest.
Should I make extra payments on my loan?▼
Making extra payments is generally beneficial if your loan has a moderate to high interest rate (above 4-5%) and there are no prepayment penalties. However, consider first: building an emergency fund, paying off higher-interest debt, and maximizing employer 401(k) matches. The best strategy depends on your overall financial situation.
What is the difference between amortization and simple interest?▼
With amortization, each payment is the same amount but the split between principal and interest changes over time. With simple interest, interest is calculated only on the original principal. Most mortgages, auto loans, and personal loans use amortization, while some short-term loans use simple interest.
When does refinancing make sense for an amortized loan?▼
Refinancing makes sense when you can get a significantly lower interest rate (typically 1% or more lower), when you want to change your loan term, or when you want to consolidate multiple debts. Consider the breakeven point: divide the closing costs by your monthly savings to see how many months until refinancing pays for itself.
