1. What is the Ooba Additional Bond Repayment Calculator?

The Ooba Additional Bond Repayment Calculator helps homeowners calculate their new monthly bond payment after making an additional payment toward their home loan principal. This tool is based on ooba's bond repayment methodology.

2. How Does the Calculator Work?

The calculator uses the following formulas:

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

Where:

\( P \) — Original principal amount (ZAR)
\( \text{Extra} \) — Additional payment amount (ZAR)
\( \text{New Balance} \) — Remaining principal after additional payment (ZAR)
\( M_{\text{new}} \) — New monthly payment amount (ZAR)
\( r \) — Monthly interest rate (decimal)
\( n_{\text{remaining}} \) — Remaining loan term in months

Explanation: The calculator first deducts the additional payment from the principal, then recalculates the monthly installment based on the reduced balance and remaining term.

3. Importance of Additional Bond Repayments

Details: Making additional bond repayments can significantly reduce the total interest paid over the life of the loan and shorten the repayment period. Even small additional payments can lead to substantial long-term savings.

4. Using the Calculator

Tips: Enter the original bond principal in ZAR, the additional payment amount in ZAR, the annual interest rate as a percentage, and the remaining loan term in months. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do additional repayments affect my bond?
A: Additional repayments reduce your principal balance, which decreases the total interest you'll pay and may shorten your loan term.

Q2: Should I reduce the monthly payment or the loan term?
A: This depends on your financial goals. Reducing the term saves more interest overall, while reducing monthly payments improves cash flow.

Q3: Are there penalties for additional bond repayments?
A: Most South African bonds allow limited additional repayments without penalties. Check your bond agreement for specific terms.

Q4: How often can I make additional repayments?
A: This varies by lender. Some allow monthly additional payments, while others may have different frequency restrictions.

Q5: Can I access the money if I need it later?
A: Some bonds have access facilities that allow you to redraw additional payments, but this depends on your specific bond product.
