Frequently Asked Questions
An amortization schedule breaks down each periodic loan payment into two components: principal and interest. Initially, a larger portion of your payment covers the interest accrued on the highest loan balance. As you pay down the principal over time, the interest charge decreases, meaning more of your fixed payment goes toward reducing the principal until the loan is fully repaid.
Making extra payments directly reduces your outstanding principal balance without incurring additional interest on that specific amount. Because your future interest charges are calculated on a lower principal, you will pay less total interest over the life of the loan and pay off your debt faster than originally scheduled.
Increasing your payment frequency, such as switching from monthly to bi-weekly payments, typically results in making the equivalent of one extra monthly payment per year. This accelerated schedule reduces your principal faster, which lowers the total amount of interest compounded over the term of the loan.
Interest is calculated periodically based on the remaining principal balance. At the beginning of the loan, your balance is at its highest, meaning the interest charge is also at its peak. As you make payments and lower the principal, the subsequent interest calculations yield smaller amounts.
This calculator is designed for standard, fixed-rate amortizing loans such as typical mortgages, auto loans, and personal loans. It may not perfectly predict the schedule for variable-rate loans, interest-only loans, or loans with complex daily compounding methods, but it provides a highly accurate estimate for standard structures.
