How Amortization Works
When you take out a loan, your fixed monthly payment is split between interest (the cost of borrowing) and principal (paying down what you owe). Early payments are mostly interest because the balance is high.
As you pay down the balance, less goes to interest and more goes to principal. This is why extra payments early in a loan have the biggest impact - they reduce the balance that interest is calculated on for all future payments.
