Amortization
Amortization is the gradual retirement of loan principal through scheduled payments that combine interest on the outstanding balance with principal reduction over the loan term.
Exam context
Math items may supply rate, term, and payment number to ask for principal vs interest split, or total interest paid. Remember: amortization retires principal; interest-only periods delay amortization until later.
How payments shift over time
Fully amortizing fixed-rate loans keep the payment constant while the interest portion declines and the principal portion grows each month. Early payments are mostly interest because interest is charged on the larger remaining balance. Negative amortization products, now rare, once allowed balances to grow when payments did not cover interest.
Amortization in underwriting and disclosures
Lenders provide amortization schedules showing remaining balance after each payment. Truth-in-Lending disclosures summarize total interest over the life of the loan. License exams may ask you to read which portion of a given payment applies to principal after a stated number of years.
Examples
Year one vs year twenty
On a 30-year fixed loan, the payment in month 12 includes far less principal than the payment in month 240 because the balance has already been reduced for 20 years.
Partial prepayment
A borrower sends an extra principal payment. The lender recalculates the schedule so the loan pays off sooner unless the borrower requested payment reduction instead, if the note allows that option.
