Tips: Enter the loan amount, annual interest rate, and loan term in years. The calculator will show your monthly payment and breakdown.
Q1: Why does most of my early payment go toward interest?
A: This is how amortization works - interest is calculated on the outstanding balance, which is highest at the beginning.
Q2: How can I pay less interest overall?
A: Make extra principal payments or choose a shorter loan term to reduce total interest paid.
Q3: What's the difference between interest rate and APR?
A: APR includes both interest rate and other loan costs, giving a more complete picture of borrowing costs.
Q4: How does refinancing affect amortization?
A: Refinancing resets the amortization schedule, typically extending the time before you build significant equity.

A: Yes, advanced versions of this calculator can show a month-by-month breakdown of your payments.
