Amortization — frequently asked questions
What is an amortization schedule?
An amortization schedule is a month-by-month breakdown of every loan payment, showing how much goes to interest, how much reduces the principal, and your running balance. It helps you see exactly when your debt ends and how much you pay in total along the way.
Why is most of my early payment interest?
At the start of the loan, the outstanding balance is highest, so the interest charged each month is largest. As you pay down the balance, the interest portion shrinks and the principal portion grows — that's why the later years of a long loan repay much faster.
How do extra payments affect my loan?
Extra payments go straight to the principal, which reduces the balance that future interest is charged on. Even small extras early in the loan can shave years off the term and save thousands in interest. Try doubling a single payment in year one to see the impact.
