Frequently Asked Questions
How much do I save by paying extra on my mortgage?
Even small extra payments add up significantly. On a $300,000 30-year mortgage at 7%, paying $200 extra per month saves about $116,000 in interest and pays off the loan about 7 years early.
Should I pay extra on my mortgage or invest?
If your mortgage rate is higher than expected investment returns, pay extra on your mortgage. If your rate is low (under 4%), investing the difference may yield better returns. Consider your risk tolerance.
What is a biweekly mortgage payment?
Paying half your monthly payment every two weeks results in 26 half-payments per year (13 full payments). This extra payment per year can pay off a 30-year mortgage 4-5 years early.
Does extra mortgage payment go to principal?
Yes, if you specify that the extra payment goes to principal. Always mark extra payments as principal-only to ensure they reduce your balance and not next month payment.
What is mortgage amortization?
Amortization is the process of paying off your mortgage in regular installments. Early payments are mostly interest; later payments are mostly principal. An amortization schedule shows the breakdown for each payment.
