Amortization
Amortization is the process of paying off a loan through regular fixed payments that gradually reduce both principal and interest.
When a loan is amortized, each scheduled payment is split between interest on the current balance and a chunk of principal. Early in the term, more of each payment goes to interest because the balance is high. As the balance falls, the interest portion shrinks and more of every payment chips away at principal. The payment amount itself usually stays level, so the mix shifts over time even though the dollar figure you send does not. A $50,000 loan at 10 percent over five years might run about $1,062 a month, with the first payments heavy on interest and the last ones heavy on principal.
Understanding amortization helps you see why a longer term lowers your monthly payment but raises the total interest you pay. Stretching the same loan over seven years instead of five drops the monthly bill but adds years of interest on top. An amortization schedule, which lists each payment and how it splits, lets you see the true cost and the balance at any point. That is useful if you might pay off early or refinance, since it shows exactly how much principal remains.
Common questions
Why does so much of my early payment go to interest?
Because interest is charged on the outstanding balance, which is highest at the start. As you pay the balance down, the interest share of each payment drops and more goes to principal.
Does a longer amortization save me money?
It lowers your monthly payment but increases the total interest paid, since you carry the balance for more periods. A shorter term costs more per month but less overall.
