Mortgage Prepayment Strategies
There are several effective strategies for prepaying your mortgage:
Monthly Prepayments
Add a fixed amount to your regular monthly payment for consistent progress.
One-time Payments
Make larger lump-sum payments when you have extra cash available.
Year-end Payments
Use tax refunds or bonuses for substantial prepayments.
Bi-weekly Payments
Make half your monthly payment every two weeks for 26 payments per year.
Types of Mortgage Prepayment
Principal-Only Prepayments
Extra payments go directly to reducing your principal balance, the most effective type.
Escrow Prepayments
Pay property taxes and insurance ahead to reduce monthly escrow payments.

Frequently Asked Questions
Common questions about mortgage prepayment and savings calculations
What is mortgage prepayment?
Mortgage prepayment involves making extra payments beyond your regular monthly mortgage payment to reduce your principal balance faster, saving interest and shortening your loan term.
How much can I save by prepaying my mortgage?
Savings vary based on your interest rate, loan balance, and prepayment amount. Generally, prepaying $100 monthly on a $300,000 loan at 4% interest can save $30,000+ in interest and pay off your loan 4-5 years early.
Should I prepay my mortgage or invest extra money?
If your mortgage rate is above 4-5%, prepaying usually makes more sense than investing in stocks. Compare your mortgage rate to expected investment returns to decide.
Are there prepayment penalties?
Some mortgages have prepayment penalties, especially older loans. Check your loan documents or contact your lender. Most modern mortgages allow prepayment without penalties.
How does prepayment affect my taxes?
Prepayments don't directly affect your tax deductions, but paying off your mortgage faster reduces your interest deduction. The tax benefit of mortgage interest is typically less than the savings from prepayment.
What's the best way to prepay my mortgage?
Start with a one-time payment if you have extra cash, then add monthly prepayments. Many lenders allow you to automatically add a fixed amount to your regular payment.
How accurate are these calculations?
Very accurate for standard fixed-rate mortgages. Actual results may vary based on your specific loan terms, fees, and lender policies. Always consult your lender for precise calculations.
Can I prepay my FHA or VA loan?
Yes, FHA and VA loans allow prepayment. However, FHA loans have a 2% prepayment penalty if you pay off the loan within the first 3 years, and VA loans may have funding fee adjustments.
