Bottom line for 2026: Extra mortgage payments beat savings accounts and CDs with zero risk. Whether they beat investing depends on your time horizon and risk tolerance — many financial advisors recommend doing both: max your 401k employer match, then split surplus between investing and mortgage prepayment.
Wells Fargo, Chase, Rocket Mortgage, Bank of America, and most US lenders have online portals where you can make extra payments. Look for "Make a Payment" or "Additional Principal Payment."
Always specify that your extra payment should go toward principal reduction. Some lenders default to applying it as a future month's payment — which saves you no interest. If you're unsure, call your lender to confirm.
Most US conventional loans (Fannie Mae/Freddie Mac conforming loans) have no prepayment penalty. Some FHA, VA, or non-QM loans might. Check your loan documents or call your servicer before making large extra payments.
Automate it — set up a recurring extra principal payment so it happens every month without thinking. Most lender portals support this. You can cancel anytime if your finances change.
Check your next mortgage statement to confirm the extra payment was applied to principal — your outstanding balance should have dropped by more than the interest amount.
Pay half your mortgage payment every 2 weeks instead of monthly. You'll make 26 half-payments = 13 full payments per year — one extra payment annually, saving years off a 30-year mortgage without feeling the difference.
The average US tax refund is around $3,000. Applied to your mortgage principal early in your loan, this alone can save over $8,000 in interest on a 30-year mortgage at 6.5%.
After a large lump sum payment, ask your lender about a mortgage recast — they recalculate your monthly payment based on the new lower balance. Cheaper than refinancing (no closing costs) and lowers your monthly payment.
Extra payments made in years 1-5 of a 30-year mortgage have the biggest impact — you're in the steepest part of the interest curve. Even $50/month in year one saves more than $200/month in year 20.
On a $300,000 mortgage at 6.5% over 30 years, $200 extra per month saves $72,100 in total interest and cuts 7 years 4 months off your loan. On a $400,000 mortgage at the same rate, the saving rises to approximately $96,200. Use our free US mortgage calculator above for your exact figures.
At 6.5-7% mortgage rates in 2026, paying extra is a guaranteed risk-free return that beats savings accounts and CDs. The S&P 500 has historically returned 7-10% annually but with significant volatility. Most financial advisors recommend: first max your 401k employer match (100% instant return), then consider splitting surplus between investing and mortgage prepayment based on your risk tolerance and time to retirement.
Log into your lender's online portal and specifically select "apply to principal" when making your extra payment. If paying by check, write "apply to principal only" on the memo line. If you're unsure, call your loan servicer — the number is on your monthly statement. Check your next statement to confirm the balance dropped as expected.
Yes — when applied to principal, extra payments reduce your outstanding balance immediately. Since interest is calculated as a percentage of your outstanding balance each month, a lower balance means less interest charged next month. Every dollar of principal reduction saves interest for every remaining month of your loan — the earlier you pay, the more you save.
Yes. FHA loans originated after January 21, 2015 cannot have prepayment penalties under HUD rules. VA loans also prohibit prepayment penalties. Most conventional Fannie Mae and Freddie Mac conforming loans have no prepayment penalty either. Always verify with your specific loan servicer, especially for older loans or non-QM products.
