The Power of Extra Principal Payments
Most home buyers only focus on the monthly payment, but the true cost of a mortgage is the interest paid over 15 to 30 years. By making consistent, small additions to your principal payment, you can drastically reduce the total amount you pay back to the bank.
When you make your regular monthly payment, a large portion goes toward interest, especially in the early years of the loan. However, 100% of any "extra" payment goes directly toward the principal balance. This reduces the balance upon which next month's interest is calculated, triggering a snowball effect of savings.
Even an extra $50 or $100 a month can shave years off a 30-year mortgage. This strategy is effectively like getting a guaranteed return on your money equal to your mortgage interest rate, risk-free and tax-free.
Our Extra Payments Calculator helps you visualize this impact. You can test different monthly amounts or one-time lump sum payments to see exactly how your payoff timeline shifts.
Frequently Asked Questions
Should I specify "Principal Only" to my lender?
Absolutely. When making extra payments, always ensure your lender knows to apply the funds to search for "Principal Balance" rather than just applying it to the next month's bill.
Is there a penalty for paying early?
Most modern conventional and FHA mortgages do not have prepayment penalties. However, some subprime or specialty loans might, so check your original loan disclosure.
What is better: extra payments or investing?
Compare your mortgage interest rate to your expected market return. If your mortgage rate is high (e.g., 7%), paying it down is a guaranteed 7% return, which is very attractive.
