Frequently asked questions
Why is early interest so high?
Interest is charged on the outstanding balance, which is largest at the start, so early payments are mostly interest.
Do extra payments help?
Yes — any extra amount goes straight to principal and removes all the future interest that balance would have generated.
What do I need to enter into the Amortization Calculator?
Just 3 values: loan amount, interest rate, term. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
