Frequently Asked Questions
What is a Loan Amortization Schedule?
An amortization schedule is a complete table detailing each periodic loan payment, showing exactly how much goes toward principal versus interest over time.
Why does the interest payment decrease over time?
Because interest is calculated on the remaining loan principal, as the principal decreases each month, the interest charge shrinks and more money goes to paying off the principal.
