In South Africa, the rates of interest may vary periodically. It is crucial to understand the implications for your monthly expenditures, particularly for significant financial commitments like home loans, vehicle financing, and credit cards.
Understanding Interest: Before delving into the calculation of loan interest, let's grasp the concept of "interest."
In simple terms, interest is the charge levied by a lender for providing funds to a borrower. In South Africa, the Reserve Bank (SARB) establishes the repurchase (repo) rate for money lent to the country's banks.
This rate serves as the baseline for interest rates charged by lenders. The standard interest rate applied by banks is termed the prime interest rate and consistently exceeds the repo rate.
Banks generate income through this interest, covering their expenses and facilitating profit.
Fluctuations in the repo rate lead to corresponding adjustments in the prime rate, impacting all monthly repayments.
Interest is always expressed as a percentage, and the actual interest paid is computed by applying this percentage to the total borrowed amount.
Calculating Interest on a Home Loan: The interest component of your loan is included in your monthly repayment, sparing you from manual calculations.
However, if you wish to determine the total interest over your loan term, this involves a somewhat complex calculation based on both the outstanding balance and the loan term.
This mechanism, known as compound interest, signifies that the amount owed to the bank increases daily.
Fortunately, online calculators, such as BetterBond's amortisation calculator, can simplify this process, revealing the breakdown of repayments into capital and interest amounts.
Paying Off Your Home Loan: Despite the daily increase in the amount owed, two factors should be considered:
Initial repayments predominantly cover interest, with a fraction allocated to the principal amount.
Paying more than the minimum amount from the outset reduces overall interest payments, shortens the repayment term, and leads to long-term savings.
Securing a Lower Interest Rate: To obtain a more favorable interest rate on your home loan, consider the following:
Make a substantial deposit to reduce the loan amount.
Budget wisely and adhere to it.
Maintain a positive credit score by consistently meeting financial obligations.
Compare offerings from different lenders to secure the best deal, possibly through a bond originator like BetterBond.
