How to Use the Amortization Calculator

An amortization calculator is a financial tool used to determine the monthly payment, total interest, and full repayment cost of a loan over time.

This calculator is especially helpful when you’re planning to take out a mortgage, car loan, personal loan, or student loan and want a clear understanding of the payment structure.

What the Calculator Does

It takes three key inputs:

1. Loan Amount – The total money you plan to borrow.
2. Interest Rate – The annual percentage interest charged by your lender.
3. Loan Term – The number of years over which you’ll repay the loan.

Using these, the calculator computes:

• Monthly payment
• Total interest paid over the term
• Total repayment amount (principal + interest)
