1. What is Bond Repayment with Extra Payments?

Bond repayment with extra payments refers to the process of making additional payments towards the principal of a bond or loan, which reduces the outstanding balance and can lead to lower monthly payments or shorter repayment terms.

2. How Does the Calculator Work?

The calculator uses the bond repayment formula:

\[ M_{new} = (P - Extra) \times \frac{r \times (1 + r)^{n_{remaining}}}{(1 + r)^{n_{remaining}} - 1} \]

Where:

\( M_{new} \) — New monthly payment (currency units)
\( P \) — Original principal (currency units)
\( Extra \) — Extra payment amount (currency units)
\( r \) — Monthly interest rate (decimal)
\( n_{remaining} \) — Remaining months (months)

Explanation: The formula calculates the new monthly payment after applying an extra payment to reduce the principal balance, while keeping the remaining term unchanged.

3. Importance of Extra Payments

Details: Making extra payments can significantly reduce the total interest paid over the life of the bond and help borrowers become debt-free faster. It provides flexibility in managing debt repayment strategies.

4. Using the Calculator

Tips: Enter the original principal amount, extra payment amount, annual interest rate, and remaining months. Ensure all values are positive and the extra payment does not exceed the principal balance.

5. Frequently Asked Questions (FAQ)

Q1: What happens if the extra payment exceeds the principal?
A: The new balance becomes zero and no monthly payment is required, as the bond is fully paid off.

Q2: Can extra payments reduce the loan term instead of the monthly payment?
A: Yes, some lenders allow borrowers to choose between reducing the monthly payment or shortening the loan term when making extra payments.

Q3: Are there penalties for making extra payments?
A: Some bonds or loans may have prepayment penalties. Always check the terms of your agreement before making extra payments.

Q4: How often can I make extra payments?
A: This depends on your loan agreement. Some allow unlimited extra payments, while others may have restrictions.

Q5: Is it better to make extra payments or invest the money?
A: This depends on the interest rate of your bond versus potential investment returns. Generally, if your bond interest rate is higher than expected investment returns, paying down debt is better.
