Continue your simulation with the CIMB flat rate vs effective rate and discover why two different percentages describe exactly the same loan.
Malaysian banks advertise personal loans with flat rates, but they must also disclose an effective interest rate. In this guide you will learn what each percentage measures, how to calculate the effective rate from a flat quote, why the gap widens with tenure, how promotions affect the comparison and how early settlement interacts with flat-rate pricing.
Direct answer: the flat rate charges interest on the original loan amount for the whole tenure, while the effective rate reflects interest on the reducing balance. For a CIMB Cash Plus loan at a 6.88% flat rate over five years, the effective rate is roughly 12.4% per year, which is the figure to compare with other loans.
At the time of writing, published CIMB Cash Plus flat rates ranged from roughly 6.88% to 14.88% per year, with promotional figures sometimes lower for selected applicants. Bank Negara Malaysia guidelines require the effective rate to appear in the product disclosure sheet, so you can find the bank’s own calculation before accepting any offer.
The common error is comparing a flat rate with a card rate or a reducing-balance loan elsewhere and concluding that the flat-rate loan is cheaper. A flat rate of 7% may sound far below a card charging 18%, yet its effective rate of about 12.6% narrows the difference considerably, and the comparison should be made on the effective figure.
Next, you will see a clear definition of both rates, the conversion method with examples, tables across tenures and rates, how promotional pricing should be judged, how early settlement rebates are calculated, practical comparison steps and a summary checklist. Keep a calculator or spreadsheet ready so you can repeat the conversions with your own offer from the bank.
Two rates, one loan
| Feature | Flat rate | Effective rate |
|---|---|---|
| Interest based on | Original principal | Outstanding balance |
| Used for | Calculating the instalment | Comparing true cost |
| Changes with tenure | No | Rises relative to flat as tenure grows |
| Shown in | Advertising and quotes | Product disclosure sheet |
Both numbers are correct descriptions of the same contract. The flat rate is convenient for calculating the instalment, while the effective rate expresses the cost in the same terms used by mortgages, car loans in many countries and international comparisons.
Converting a flat rate step by step
- Calculate total interest: principal × flat rate × years.
- Find the instalment: (principal + interest) ÷ months.
- Solve P·r/(1−(1+r)^−n) = instalment for the monthly rate r.
- Multiply r by twelve to obtain the annual effective rate.
For RM25,000 over five years at 6.88% flat, interest is RM8,600 and the instalment RM560. Solving for r gives about 1.03% per month, or roughly 12.4% per year. A spreadsheet RATE function performs this step instantly: RATE(60, -560, 25000) × 12.
How tenure widens the gap
| Flat rate 6.88% | Instalment on RM25,000 | Effective rate |
|---|---|---|
| 1 year | about RM2,227 | about 12.5% |
| 3 years | about RM838 | about 12.6% |
| 5 years | about RM560 | about 12.4% |
The ratio between effective and flat rates stays close to 1.8 for common tenures, which is a useful rule of thumb. What changes dramatically with tenure is the total interest: RM1,720 for one year against RM8,600 for five years. Even when the percentage looks similar, the ringgit amount is not.
Comparing different flat rates
| Flat rate | Approximate effective rate | Interest on RM25,000 over 5 years |
|---|---|---|
| 4.38% | about 8.0% | RM5,475 |
| 6.88% | about 12.4% | RM8,600 |
| 9.88% | about 17.4% | RM12,350 |
| 14.88% | about 25.0% | RM18,600 |
Judging promotional rates
Promotions may advertise a low flat rate for certain tenures, amounts or customer groups. Check whether you meet every condition, such as minimum loan size, specific tenure, salary crediting or a limited application window. If you must borrow more than you need to qualify, the promotion may not be worth it.
- Confirm the effective rate of the promotional offer.
- Check whether insurance is bundled with the promotion.
- Compare the total repayable with a standard offer.
- Read any clawback conditions for early settlement.
Early settlement and the Rule of 78
When a flat-rate loan is settled early, the bank calculates a rebate on interest not yet earned. Some agreements use the Rule of 78, which allocates more interest to the early months, so the rebate is smaller than a simple proportional calculation would suggest. Others use a method set by the bank and disclosed in the agreement.
Early settlement fees may also apply. Request a written settlement statement before you decide, and compare the saving with alternatives such as keeping the loan and building savings. Settling a loan in its final year rarely saves much interest because most has already been charged.
A practical comparison routine
- Collect the product disclosure sheet for each offer.
- Note the effective rate and all fees.
- Calculate the total repayable in ringgit.
- Check the impact on your debt service ratio.
- Choose the lowest total that fits your budget.
A side-by-side example
Suppose CIMB offers RM25,000 over five years at a 6.88% flat rate, while a digital lender offers the same amount and term at an effective rate of 11.5% on a reducing balance. The CIMB instalment is RM560 and total interest RM8,600. The digital loan instalment is about RM550 and total interest about RM7,990. In this case the second offer is slightly cheaper.
Now imagine the digital lender charges a processing fee of RM750 deducted from the disbursement. Adding it changes the comparison: the effective cost rises above the CIMB loan. This shows why you need both the effective rate and every fee to reach a reliable conclusion.
- List the instalment, total interest and fees for each offer.
- Note the net amount you actually receive.
- Compare total repayable minus net amount received.
Why banks still quote flat rates
Flat rates remain common because they are simple to explain and easy for borrowers to calculate. They also make the instalment look clearly fixed from the first month. The effective rate does not replace the flat rate, but it adds the context needed for comparison. Using both gives you a complete view of the loan.
Questions to ask CIMB before accepting
- What effective rate applies to my tenure and amount?
- Is stamp duty or insurance deducted from the disbursement?
- How is the early settlement rebate calculated?
- Are there late payment charges and how are they computed?
Getting clear written answers to these questions turns the comparison into a straightforward calculation and avoids surprises during the tenure.
Summary: flat and effective rates
The flat rate calculates the instalment; the effective rate reveals the true annual cost. For CIMB Cash Plus and other Malaysian loans, compare offers using the effective rate and the total repayable.
- Flat rate charges interest on the original amount.
- Effective rate is about 1.8 times the flat rate.
- Total interest grows in line with tenure.
- Promotions need careful reading of conditions.
- Early settlement rebates may be smaller than expected.
Frequently asked questions
Where can I find the effective rate for my CIMB offer?
It is listed in the product disclosure sheet provided before you accept the loan.
Is a flat rate always worse than a reducing-balance rate?
Not always, but you can only tell by comparing effective rates or total repayable.
Can I negotiate the flat rate?
Applicants with strong profiles may receive better pricing, so it is worth asking.
Conclusion
Understanding the CIMB flat rate vs effective rate prevents one of the most common borrowing mistakes in Malaysia. Use the flat rate to check the instalment, the effective rate to compare offers and the total repayable to make the final decision about your Cash Plus loan.
