Did You Know?
How Do Extra Payments Work?
Principal Reduction
Extra payment reduces balance immediately. Next month's interest is calculated on lower balance, so you save on every future payment.
Timing Matters
Early extras save more because the balance is highest. A $200 extra in year 1 saves more than the same in year 15.
Biweekly
Pay half the monthly payment every 2 weeks. 26 payments = 13 full payments per year instead of 12. Saves interest without doubling payment.

Frequently Asked Questions
How do extra mortgage payments work?
Extra payments go directly to principal, reducing your balance. That cuts future interest and shortens the loan term. Specify "apply to principal" when making the payment—don't just pay ahead on the next due date.
Where do extra payments go?
Extra payments should be applied to principal, not to future monthly payments. Some lenders apply extra to next payment by default—confirm with your lender and specify "principal only."
How much can extra payments save?
$200/mo extra on a $300K loan at 6.5% can save ~$67K in interest and pay off ~7 years sooner. The earlier you start, the more you save. First-year extra payments have the biggest impact.
What's the best extra payment strategy?
Consistent monthly extra is powerful. One extra payment per year (or biweekly = 13 payments/yr) also works. Apply windfalls (bonus, tax refund) to principal. Earlier payments save more than later ones.
One-time vs monthly extra—which is better?
Monthly extra has a bigger impact because it reduces the balance every month, compounding savings. A one-time lump sum helps but doesn't match the cumulative effect of consistent monthly extras.
Should I invest instead of making extra payments?
If investment returns exceed your mortgage rate (after tax), investing may be better. With rates ~6–7%, it's a close call. Extra payments are guaranteed savings; investments carry risk. Consider both.
