1. What is the Bond Repayment Calculator with Extra Payment?

The Bond Repayment Calculator with Extra Payment calculates the adjusted monthly payment after making an extra payment toward the principal. It helps borrowers understand how extra payments can reduce their monthly obligations and overall interest costs.

2. How Does the Calculator Work?

The calculator uses the bond repayment formula with extra payment:

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

Where:

\( P \) — Original principal amount
\( \text{Extra} \) — Extra payment amount applied to principal
\( \text{New Balance} \) — Remaining principal after extra payment
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n_{\text{remaining}} \) — Remaining number of months in the loan term
\( M_{\text{new}} \) — New monthly payment amount

Explanation: The formula first reduces the principal by the extra payment amount, then recalculates the monthly payment based on the new balance and remaining term.

3. Importance of Extra Payment Calculations

Details: Making extra payments toward principal can significantly reduce total interest paid and shorten the loan term. This calculator helps borrowers plan their repayment strategy and understand the financial impact of additional payments.

4. Using the Calculator

Tips: Enter the original principal amount, the extra payment you plan to make, the annual interest rate, and the remaining number of months. Ensure all values are positive and the extra payment does not exceed the remaining principal.

5. Frequently Asked Questions (FAQ)

Q1: How do extra payments affect my loan?
A: Extra payments reduce the principal balance, which decreases the total interest paid and may lower your monthly payments if you recalculate the amortization.

Q2: Should I make extra payments or invest the money?
A: This depends on your loan interest rate vs. potential investment returns. Generally, if your loan rate is higher than expected investment returns, paying down debt is better.

Q3: Can I make extra payments on any type of loan?
A: Most loans allow extra payments, but some may have prepayment penalties. Check your loan agreement before making extra payments.

Q4: What's the difference between recasting and refinancing?
A: Recasting recalculates payments with the same terms after extra payments, while refinancing involves getting a new loan with different terms.

Q5: How often can I make extra payments?
A: This varies by lender. Some allow unlimited extra payments, while others may have restrictions. Check with your lender for specific policies.
