Amortization is the process of paying off a loan with regular payments over time. Early payments are mostly interest; later payments shift toward principal. This calculator shows your monthly payment breakdown and how much total interest you will pay over the full loan term. Understanding your amortization schedule helps you decide whether to make extra payments to save on interest.
Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.
What is negative amortization?
Negative amortization occurs when your payment is less than the interest owed, causing the loan balance to grow instead of shrink. This calculator assumes fully amortizing payments that eliminate the balance by the end of the term.
How do extra payments affect amortization?
Any extra amount paid toward principal reduces the remaining balance and the total interest charged. Even small additional monthly payments can shorten the loan by years and save thousands in interest.
