What You Need to Know (TL;DR)
Enter the remaining balance and the years and months still left. The calculator amortizes that balance over the remaining term. It does not treat the balance as a brand-new loan. The starting rate is the Freddie Mac 30-year survey. The biweekly option is an approximation of one extra monthly payment a year.
Pacing Your Payoff in the Houston Market
When you sign a 30-year mortgage, the bank front-loads the interest. In the first 10 years of your loan, the majority of your monthly payment goes toward bank profits, not your home's principal.
By making extra payments, you force that money directly into the principal. Read our full breakdown on How Extra Mortgage Payments Affect Your Loan for detailed amortization schedules.

Frequently Asked Questions (FAQ)
How does paying extra on my mortgage save me money?
Every extra dollar you pay goes directly toward your principal balance. Since your daily interest charge is calculated based on your outstanding principal, lowering the principal early reduces all future interest charges exponentially.
What is a biweekly mortgage payment?
Instead of making one full payment a month, you pay exactly half your mortgage every two weeks. Since there are 52 weeks in a year, you make 26 half-payments, which equals 13 full payments. That one extra payment per year can shave years off a 30-year loan.
Are there prepayment penalties in Texas?
The vast majority of standard conventional, FHA, and VA loans in Texas do not have prepayment penalties. However, always check your specific loan documents before making large lump-sum principal payments to ensure you aren't charged a fee.
Should I invest my extra cash or pay down the mortgage?
This depends entirely on your mortgage interest rate versus your expected investment return. If you have a 3% mortgage rate, mathematically, investing in the stock market (historically yielding 7-10%) is better. If your mortgage rate is 7%, paying it off early is like getting a guaranteed 7% risk-free return on your money.
