Principal Reduction
Any payment made toward the loan balance beyond the scheduled monthly principal amount.
A principal-reduction payment goes straight to lowering the loan balance, not to next month's payment. On a standard amortizing mortgage with no prepayment penalty, every extra dollar applied to principal saves you the full compounding interest that dollar would have generated over the remaining life of the loan.
There are several patterns: a single lump sum (after a bonus or tax refund), a small recurring extra each month (one-thirteenth of a payment shaves years off a 30-year loan), or biweekly payment schedules that effectively add one extra monthly payment per year.
Always confirm with your servicer that extra payments are being applied to principal rather than to future scheduled payments. Most online portals have a clearly labeled principal-only payment option; check the statement the following month to verify.
