About This Amortization Calculator

An amortization schedule is a complete table of periodic loan payments showing the amount of principal and interest that comprise each payment until the loan is paid off. While your total payment remains the same, the ratio of principal to interest changes over time.

This amortization calculator allows you to model mortgages, auto loans, personal loans, and business loans. It provides three distinct modes: standard schedule generation, term-based calculation in months, and an advanced mode to see how extra monthly payments can drastically reduce your total interest and payoff time.

Switch payment frequency from monthly to biweekly to see how making 26 half-payments per year - the equivalent of 13 full monthly payments - can shave years off a 30-year mortgage and save a substantial amount in interest.

How to Use This Calculator

  1. 1

    Enter your loan details

    Input the loan amount, annual interest rate, and loan term in years. These three numbers define your entire loan structure.

  2. 2

    Choose payment frequency

    Select monthly (most common), biweekly, or weekly. Biweekly payments result in one extra full payment per year, significantly reducing your total interest on long-term loans.

  3. 3

    Model extra payments (optional)

    Switch to the Extra Pay tab and enter an additional amount to pay each period. The calculator will show you exactly how much interest you save and how many years sooner you'll be debt-free.

  4. 4

    Review the amortization schedule

    Toggle between the Yearly view (one row per year) and Full Schedule (every single payment). Notice how early payments are mostly interest - this shifts gradually toward principal over the loan term.
