How to use this tool
Enter the original loan amount, interest rate, term, and your planned extra monthly payment. Compare the standard schedule with the accelerated payoff to see months and interest saved.
Worked example
Example: a $200,000 mortgage at 6.5% for 30 years with an extra $200/month saves about 6 years and roughly $55,000 in interest versus the standard payment alone.
How it works
Enter your loan amount, interest rate, term, and an extra monthly payment. The calculator compares the standard amortizing schedule with one that includes the extra payment, then shows months saved and interest saved. Fees and taxes are not included.

Frequently asked questions
How do extra payments save money?
Extra amounts go toward principal, so the balance drops faster and less interest accrues over the life of the loan.
Is the extra payment applied every month?
Yes. The estimate assumes the same extra amount is paid with every monthly installment until the loan is paid off.
Does this include fees or prepayment penalties?
No. Results are estimates based only on principal, rate, term, and extra payment.
