What is Loan Amortization?
Loan amortization is the process of paying off a loan over time through fixed monthly payments. Each payment is split into two parts: interest and principal.
At the beginning of the loan, a larger portion of each payment goes toward interest. As the balance falls, more of each payment goes toward principal.
How Amortization Works
The monthly payment is based on your loan amount, interest rate, and loan term. The payment stays fixed, but the composition changes over time.
r = monthly interest rate
n = total number of months

- See how fast your balance decreases
- Compare loan terms more clearly
- Plan extra payments to save money

Frequently Asked Questions
An amortization schedule is a table that shows each payment over time, including how much goes toward interest and how much reduces the principal balance.
Interest is calculated on the remaining loan balance. Since the balance is highest at the start, more of the early payments go toward interest.
Yes. You can reduce total interest by making extra payments, choosing a shorter loan term, or securing a lower interest rate.
Paying off your loan early reduces the total interest you pay because interest is charged only on the remaining balance.
A longer loan term lowers your monthly payment but increases total interest paid. A shorter term means higher payments but less total cost.
The interest rate is the cost of borrowing, while APR includes additional fees and gives a more accurate representation of total loan cost.
