Refinancing a Personal Loan: When It Helps and When It Hides the Cost
Summary
Refinancing is only worth doing if the total you will repay falls. A lower monthly instalment proves nothing on its own, because it can come entirely from a longer tenure. Add the settlement figure on the old loan, the charges on the new one, and the full schedule of new instalments, then compare that against simply continuing to pay what you have.
Refinancing does not reduce debt, it replaces one debt with another. Whether that is an improvement depends on a single comparison, and it is not the comparison most borrowers are shown.
The only comparison that settles it
Put two totals side by side.
- Staying put. The remaining instalments on your current loan, added up.
- Refinancing. The settlement figure to close the old loan, plus every charge on the new one, plus the full schedule of new instalments added up.
If the second number is not meaningfully smaller than the first, refinancing is costing you money while feeling like relief.
Why a lower instalment proves nothing
An instalment can fall for two very different reasons: a genuinely lower rate, or a longer tenure. Only one of those saves money. A loan with four years left, refinanced into a seven year facility at a similar rate, will have a smaller instalment and a larger total cost.
This is the most common way refinancing is mis-sold, and the arithmetic above catches it immediately.
The settlement figure is not the outstanding balance
Closing the old loan early may trigger a rebate calculation rather than a simple balance payoff. Where the Rule of 78 applies, the amount required can be higher than you expect, because interest was front loaded. That method is prohibited for personal financing from 1 January 2027 under the Bank Negara Policy Document on Personal Financing, but agreements written before that date may still use it.
Always obtain the settlement figure in writing before committing to refinance. It is an input to the decision, not a detail to handle afterwards.
When refinancing genuinely helps
- When your credit standing has improved enough to access a materially lower rate, and you keep the tenure the same or shorter.
- When consolidating several high cost debts into one lower cost facility, and you do not then re-use the cleared credit lines.
- When moving from a flat rate structure to a reducing balance one and you intend to settle early.
When it does not
- When the only improvement is a smaller instalment from a longer term.
- When upfront charges on the new facility eat the rate saving.
- When consolidation frees up credit cards that then get used again, which turns one debt into two.
In short
Compare totals, not instalments. If nobody will show you both totals in writing, you have your answer.
