Tenure is the most powerful lever you have when shaping a personal loan, and the most commonly misused. Stretching from 24 months to 60 months almost always cuts the monthly payment in half — which feels like a win — but it can more than double the total interest you pay over the life of the loan.
The monthly vs total tradeoff
Take a 10,000 loan at a 9% APR. Here is roughly how the same loan looks at four different tenures:
- 12 months — monthly ~875, total interest ~497
- 24 months — monthly ~457, total interest ~973
- 36 months — monthly ~318, total interest ~1,455
- 60 months — monthly ~208, total interest ~2,455
The monthly payment drops by 76% from the shortest to longest tenure. The interest paid grows by almost 400%. Same principal. Same rate. Different decision.
When a longer tenure is the right call
A longer tenure is genuinely useful when:
- The monthly payment at a shorter tenure would push your DSR above what the bank approves.
- You need predictable, comfortable cash flow during a known transition (new job, child, relocation).
- You expect income to grow and plan to use early prepayment to shorten the effective tenure later.
When a shorter tenure wins
A shorter tenure is the better answer when:
- You can fit the higher instalment without pushing other essentials.
- The loan is for a short-lived purpose (renovation, wedding, one-time medical bill).
- You want to free up borrowing capacity again as quickly as possible.
The 36-month sweet spot
For most unsecured personal loans in SEA markets, 24–36 months sits in a comfortable middle: the monthly payment is well under half of the 12-month figure, while total interest is still under 1.5x. Anything past 60 months for an unsecured personal loan should trigger a hard question of whether the loan is really appropriate — or whether the underlying spend should be downsized.
How to test tenure choices in practice
- Pick the loan amount you actually need (not the maximum offered).
- Choose the tenure where the instalment stays under ~30% of monthly net income.
- From those, pick the shortest tenure you can afford with a comfortable buffer.
- Confirm by inspecting total repayment, not just the monthly figure.
