常見問題
- How do extra payments save interest?
- Every extra dollar goes straight to principal, so less balance accrues interest each month. The loan is repaid sooner and total interest drops.
- What does the calculator show?
- The total interest saved and the number of months shaved off the term when you add your chosen extra amount to each payment.
- Are there downsides to overpaying?
- Check for prepayment penalties and weigh the guaranteed interest saving against other goals like higher-return investments or clearing costlier debt first.
- Where are my loan figures processed?
- In your browser. The balance, rate, term, and extra payment you enter drive the amortisation math locally and are never transmitted.
