How the mortgage payoff calculator works
This tool amortizes your loan month by month, adding your chosen extra amount to principal each period. Every month it charges interest on the balance (balance times the monthly rate), applies your payment, and reduces the balance by the leftover principal plus the extra. Because the extra cuts principal directly, later interest charges shrink, so the loan ends early and total interest falls.
On a $400,000 loan at 6.75%, the scheduled payment is about $2,594 and the loan runs the full 30 years with roughly $534,000 in interest. Add $200 a month toward principal and the balance clears in about 24.3 years instead of 30, cutting nearly 5.7 years off the term and saving close to $119,000 in interest over the life of the loan.
Extra principal is a guaranteed return equal to your mortgage rate, which is appealing when insurance and HOA costs already stretch a South Florida budget and every dollar counts. Florida has no state income tax, so there is no state deduction lost by paying down faster. Keep a cash reserve for hurricane deductibles and rising premiums first, then direct surplus to principal, and confirm your servicer applies extra payments to principal.
