How Stretching the Tenure Changes What a Loan Really Costs
Summary
Lengthening a loan lowers the instalment and raises the total interest, because you are borrowing the same money for longer. On RM30,000 at 8 per cent on a reducing balance, three years costs about RM3,800 in interest while seven years costs about RM9,200. Bank Negara capped personal financing tenure at ten years in its September 2025 policy document.
A longer tenure is not a cheaper loan, it is a smaller instalment. The two get confused constantly, and the confusion is expensive. Stretching repayment lowers what leaves your account each month while raising what leaves it in total, because you are borrowing the same money for a longer time.
The same loan at four different lengths
Take RM30,000 at 8 per cent on a reducing balance. Figures are rounded and illustrative, but the shape is what matters:
| Tenure | Monthly instalment | Total interest |
|---|---|---|
| 3 years | about RM940 | about RM3,840 |
| 5 years | about RM608 | about RM6,490 |
| 7 years | about RM468 | about RM9,270 |
| 10 years | about RM364 | about RM13,680 |
Going from three years to seven cuts the instalment by about half and more than doubles the interest. Going to ten years cuts the instalment further and costs roughly RM9,800 more than the three year version.
When the longer tenure is still the right choice
Paying more in total can be the correct decision. The question is whether the shorter instalment is genuinely affordable.
- If a three year instalment would leave no margin for an unexpected bill, a five year loan you can actually service beats a three year loan you default on. A missed payment costs far more than the extra interest.
- If your income is irregular, sizing the instalment to a bad month rather than an average month is prudent.
- If the lender allows early settlement on a reducing balance, you can take the longer tenure for safety and pay it down faster when cash allows.
That last point depends entirely on the rebate method, which is covered separately on this site.
The trap in the middle
The common mistake is choosing the tenure to reach a desired instalment, then borrowing more because the instalment now looks affordable. That is how a RM20,000 need becomes a RM35,000 loan. Decide the amount first, on what you need rather than what you qualify for, and only then choose the tenure.
What the rules now say about length
Bank Negara Malaysia set a maximum tenure of ten years for personal financing in its Policy Document on Personal Financing issued on 30 September 2025. The same document also introduced a financial education requirement for applicants borrowing above RM100,000.
In short
Pick the shortest tenure whose instalment you could still pay in a bad month. That one rule gets the trade-off right most of the time.
