Rule of 78
The essence of this rule may not look as glamorous to borrowers as the name sounds. The rule of 78 was previously introduced by us in another article, please refer to the article “How Banks Fooled You with the Rule of 78” to fully understand the idea. In the interest of time, we will give you a brief idea of what the rule means.
Essentially, the rule of 78 is another way of charging interest in every instalment period. Unlike flat interest rates, the rule of 78 only makes borrowers pay much more interest in the first few periods while the total interest payment for the entire loan tenure remains the same as the total interest payment of a flat interest rate loan. When the repayment of the loan slowly reaches maturity, the interest portion of your monthly payment will taper down.
If you have read our article “How Banks Fooled You with the Rule of 78”, you would have seen the example where 73% of the total interest payable is paid to the banks by the 6th month in a one-year loan that uses the rule of 78 methods.
So how does this apply to a car loan? We will explore how much interest can be saved by making an early settlement in different life stages of the loan. We expect that the later you make an early settlement, the less productive the settlement is. The effect is caused by the rule of 78.
Let's use an RM50,000 car loan with the following as an example:
Scenario 1
-
Tenure = 7 years (84 months)
-
Interest rate (per annum) = 3%
-
Number of instalment paid = 30 months
-
Early settlement penalty = RM0
Using our car & personal loan calculator, the early settlement amounts to RM34,684 with a total rebate of RM4,209. Based on our calculation using the cash flow method, the effective interest (per year) saved due to early settlement is 4.33%.
However, if we decide to make an early settlement after we have already paid 60 months of instalments, the result looks very different:
Scenario 2
-
Tenure = 7 years (84 months)
-
Interest rate (per annum) = 3%
-
Number of instalments paid = 60 months
-
Early settlement penalty = RM0
Again, using our car & personal loan calculator, the early settlement amounts to RM16,473.95. The effective interest (per year) saved due to early settlement is only 0.55%! How does this make sense to you?
Well, if you invest the same amount of money in Fixed Deposit instead of paying off the early settlement, you will earn an approximate return of 3.3%. Alternatively, you could also invest in unit trust or stocks which might potentially give you an average return of 6%. Looking purely from a financial perspective, you would not want to make the early settlement in scenario 2 because you could easily make a return higher than 0.55% by investing the money in financial products.
We have made two charts to illustrate our points above. Both the total rebate from settlement and effective interest saved decreases exponentially as we make early settlements after we have paid more and more instalments.
How do you make a decision?
You should calculate the effective interest rate you would save by making the early settlement. Then compare the effective interest rate with the return of the financial products that you would otherwise invest in (such as fixed deposits, bonds, stocks, and unit trusts) using the same amount of money you would pay for early settlement.
If the effective interest rate is higher than the return of the financial products, it makes sense to make the early settlement. Conversely, if the effective interest rate is lower than the return of the financial products, you should not make an early settlement.
Key points to remember
In the discussion above, we introduced you to the brief concept of the rule of 78 that is popularly used by banks when giving car loans and personal loans to borrowers. Rule 78 benefits the banks because borrowers would pay more interest at the initial stages of an instalment period although the amount of monthly payment remains the same.
Therefore, when you make an early settlement after the initial stages, you would have already paid a hefty amount of interest to banks.
Do consult us before making decision on whether you should make an early settlement or use our car loan/ personal loan settlement calculator to find out the total rebate from the settlement.
