What the result means
The calculator compares the scheduled payment with the scheduled payment plus your extra monthly amount. It assumes the extra payment immediately reduces the outstanding principal.
Your lender may apply extra payments differently, and fees or changes in the interest rate can change the result.

Frequently asked questions
How can an extra bond payment help?
An extra payment can reduce principal sooner, which may reduce the interest charged later when the rate remains constant.
Will extra payments always shorten the loan?
The mathematical model assumes the extra amount reduces principal immediately. Your lender's payment rules can differ.
Why does the interest saving change with the extra payment?
A larger extra payment reduces the outstanding balance faster, leaving less principal on which future interest is calculated.
