| From: | To: |
A lump sum mortgage payment is an extra payment made toward your mortgage principal beyond your regular monthly payments. This payment reduces your outstanding loan balance, which can significantly decrease the total interest paid over the life of the loan.
The calculator uses the following formula:
Where:
Explanation: The calculator computes standard mortgage amortization both with and without the lump sum payment to determine your interest savings.
Details: Making lump sum payments can help you pay off your mortgage faster, build equity quicker, and save thousands of dollars in interest payments over the life of your loan.
Tips: Enter your original loan amount, annual interest rate, loan term in years, and the lump sum amount you plan to pay. All values must be positive numbers.
Q1: How much can I save with a lump sum payment?
A: The savings depend on your loan amount, interest rate, and the size of your lump sum payment. Even small lump sums can result in significant long-term savings.
Q2: When is the best time to make a lump sum payment?
A: The earlier you make extra payments, the more interest you'll save. However, any time during your mortgage term can provide benefits.
Q3: Are there penalties for lump sum payments?
A: Some mortgages have prepayment penalties. Check your mortgage agreement before making extra payments.
Q4: Should I invest instead of making lump sum payments?
A: This depends on your mortgage interest rate vs. potential investment returns. Generally, if your mortgage rate is higher than expected investment returns, paying down debt may be better.
Q5: How often can I make lump sum payments?
A: This varies by lender. Some allow unlimited extra payments, while others have annual limits. Check with your mortgage provider.
