How the Extra Loan Payment Calculator works
The regular payment comes from the standard amortization formula. Each month the extra amount goes straight to principal, so the balance falls faster and less interest builds up. On $200,000 at 6.5% for 30 years, an extra $200 a month saves roughly $90,000 of interest. Check that your lender applies extra money to principal.
