Personal Loan Flat Rate vs Reducing-Balance Rate in Malaysia

The short answer: A personal loan advertised at 6% flat is not automatically cheaper than one quoted at 8% reducing balance. For a RM30,000 loan over 5 years, the 6% flat example costs RM9,000 in interest, while the 8% reducing example costs RM6,498. That is RM2,502 more for the lower-looking flat rate, before any fees in the examples.

Why a 6% flat rate is not the same as 6% reducing

A flat rate calculates interest using the original loan amount for the whole tenure. In the RM30,000 example, the interest calculation continues to use RM30,000 even as your monthly payments reduce what you owe.

A reducing-balance rate works differently. Interest is charged only on the amount still owed. As the balance falls, the amount used to calculate interest also falls. This is why a flat rate always costs more than the same number quoted as a reducing-balance rate.

The advertised percentage therefore needs context. “6%” does not tell you enough until you know whether it is flat or reducing balance, how long the loan lasts, and what the instalment and total repayment are.

A useful way to translate the headline is to compare the flat rate with its reducing-balance equivalent. For the example over 3 years, 6% flat is equivalent to 11.1% reducing balance. For the example over 5 years, the same 6% flat quote is equivalent to 10.8% reducing balance.

Those equivalent figures are not extra charges added to the loan. They make the pricing easier to compare with an offer that uses a reducing-balance method. The important point is that 6% flat should not be read as if it were 6% reducing balance.

What the 6% flat examples actually cost

The total repayment gives you a clearer view than the headline rate. Here are the figures for the same RM30,000 loan at different tenures:

The 5-year option has the lower monthly instalment: RM650 compared with RM983.33. That can make the longer tenure look more comfortable when you are checking your monthly budget.

However, the lower monthly payment comes with a higher total cost. The 5-year example pays RM3,600 more in interest than the 3-year example. Choosing 3 years instead of 5 years saves RM3,600 in interest under these assumptions.

This is the trade-off to look for when a lender presents several tenure choices. A longer tenure spreads repayment over more months, but the balance remains outstanding for longer and the total interest rises. A shorter tenure costs more each month, but the total repayment is lower in this example.

These examples assume no processing fee, stamp duty or insurance is added to the loan. They are educational examples, and the 6% flat and 8% reducing offers are examples rather than market rates.

Why the higher quoted rate can be cheaper

Now compare the 5-year 6% flat example with a second lender’s 8% reducing-balance offer. The second lender’s quoted percentage is higher, but the rate method changes the result.

The 6% flat offer has a monthly instalment of RM650 and total repayment of RM39,000. Its total interest is RM9,000.

The 8% reducing offer has a monthly payment of RM608.29 and total interest of RM6,498. Its monthly payment and interest cost are lower in this comparison, even though 8% looks higher than 6% in the advertisement.

The difference in interest is RM2,502. That is the practical reason to compare the total repayment rather than choosing the smallest-looking percentage.

This does not mean every 8% reducing offer is cheaper than every 6% flat offer. The result depends on the loan amount, tenure, instalment calculation and fees shown for that offer. It does mean that the rate label alone is not a fair price comparison.

When looking at an offer, write down four items together: the rate type, the quoted rate, the monthly instalment and the total repayment. If one of those is missing, the comparison is incomplete.

How to judge the tenure against your budget

Tenure is both a monthly-budget choice and a total-cost choice. The 3-year example has total interest of RM5,400 and total repayment of RM35,400. The 5-year example has total interest of RM9,000 and total repayment of RM39,000.

Start by checking whether the stated instalment fits your regular budget after ordinary commitments. Then look at the total repayment, because a smaller payment can come from spreading the debt over a longer tenure rather than from a cheaper offer.

Use a written comparison instead of relying on memory. Put each offer in its own column and record the loan amount, rate type, tenure, monthly instalment, total interest, total repayment and fees. This makes it easier to spot whether two offers are genuinely like-for-like.

If the longer tenure is being considered because of monthly cash flow, note that reason beside the comparison. If it only looks attractive because the instalment is smaller, give the total repayment equal attention before deciding.

What the Product Disclosure Sheet tells you

Lenders give you a Product Disclosure Sheet before you sign. It sets out the instalment, total repayment and fees, so use that document as the main comparison point instead of relying on a headline advertisement.

Check these items line by line:

• Rate method: Confirm whether the quoted rate is flat or reducing balance. Do not compare the percentages until this is clear.
• Monthly instalment: Match the stated payment against your own monthly budget. The 5-year example has a lower instalment than the 3-year example, but it costs more in total.
• Total repayment: This shows the full amount scheduled for repayment under the offer. It is more useful than the rate on its own.
• Tenure: Confirm the number of years and the number of months. The examples use 36 months for 3 years and 60 months for 5 years.
• Fees: Look for every fee listed in the Product Disclosure Sheet. The examples above assume no processing fee, stamp duty or insurance is added, so a real offer can only be compared properly after its listed fees are included.

Ask the lender to explain any term you cannot match to one of these items. In particular, ask whether the total repayment already includes the stated fees and whether the advertised rate is flat or reducing balance. Keep the answer beside the Product Disclosure Sheet while comparing offers.

Three checks to make before signing

A short final check can catch mistakes that a headline rate hides:

• Match the loan amount: Make sure the offers are based on the same amount. A lower repayment on a smaller loan is not a like-for-like comparison.
• Check the rate method in writing: Look for “flat” or “reducing balance” in the Product Disclosure Sheet rather than relying on how the salesperson describes the rate.
• Ask about listed fees: Confirm which fees are included in the total repayment and which are payable separately. The examples here assume no processing fee, stamp duty or insurance is added.

If the instalment, total repayment or fee treatment is unclear, ask for the relevant line in the Product Disclosure Sheet to be explained before you sign. The key question is: “What will I pay in total, including the listed fees, and what is the rate method?”
