About this digital tool
The amortization schedule shows, month by month, how each loan payment is split between principal and interest, and how much debt remains after each payment. Enter the loan amount, the annual rate and the term, and the tool builds the full repayment plan. The monthly payment stays the same, but its makeup changes: at first interest is the bigger part, and as the debt shrinks the principal share grows.
This view helps you understand how much interest you are really paying, why the debt falls slowly in the early years, and how an extra payment or early repayment affects things. It is useful for any bank loan, mortgage, personal loan or car loan. The result is an estimate and does not include fees or insurance.
How to use
- Enter the loan amount, rate and term.
- See the month-by-month table with the principal/interest split.
- See how the balance changes over time.
Frequently asked questions
Why do I pay more interest at the start?
Interest is calculated on the remaining balance. At the start the balance is high, so interest makes up most of the payment. Over time the balance falls and more goes to principal.
What is an amortization schedule?
It is a plan with all the loan payments, showing for each month the payment, the interest part, the principal part and the remaining balance. Banks usually give it to you with the contract.
How is the interest part of a payment calculated?
The month's interest = remaining balance × annual rate ÷ 12. The principal part is the payment minus this interest. Because the balance falls, interest shrinks every month.
How does an extra payment affect the schedule?
An extra payment goes entirely to principal, lowers the balance and lowers the interest in the following months. This shortens the term or reduces total interest, depending on your agreement with the bank.
