Amortization is the process of paying off a loan over time through scheduled payments. With most mortgages, each payment includes principal and interest.
How amortization works
At the beginning of a mortgage, a larger portion of the monthly payment usually goes toward interest. Over time, more of each payment goes toward principal. This gradual shift is part of the amortization schedule.
Principal vs. interest
- Principal is the amount borrowed
- Interest is the cost of borrowing
- Early payments are often more interest-heavy
- Later payments usually reduce the balance faster
- Extra principal payments may reduce interest over time

Why amortization matters
Understanding amortization can help borrowers see how loan term, rate, and extra payments affect total interest and payoff timing.
Shorter term vs. longer term
A shorter loan term may result in a higher monthly payment but less total interest over time. A longer loan term may lower the monthly payment but increase total interest paid across the life of the loan.
Extra payments
Some borrowers make extra payments toward principal to reduce the balance faster. Before doing this, confirm how your servicer applies extra payments and whether your loan has any restrictions.
