How personal loans work

A personal loan is straightforward: a lender gives you a fixed amount of money, and you pay it back in equal monthly instalments over a set time period — usually anywhere from 3 months to 5 years.

Unlike a credit card, there’s no revolving credit. You borrow once, and you repay based on a fixed schedule. That predictability is one reason people prefer personal loans when they need a clear repayment plan.

In Singapore, personal loans are offered by two types of lenders: licensed banks and licensed moneylenders. Both are legal options, but they work differently — and knowing the difference matters. We’ll cover that more in How to compare loan offers.

Every month, your repayment covers two things: the principal (the amount you originally borrowed) and the interest (the cost of borrowing).

Your loan tenure — how long you take to repay — directly affects both your monthly payment and total cost. A longer tenure means smaller monthly payments, but you’ll pay more interest overall. A shorter tenure costs you less in the long run, but your monthly payments will be higher.

Here’s a simple way to think about it. Imagine borrowing $5,000 at the same interest rate of 5% a year. The only thing that changes is how long you take to repay.

Over 12 months, your monthly payment is higher, but you’re done quickly and pay less interest in total because the lender has lent you money for a shorter time.

Over 36 months, your monthly payment is lower. However, the lender is lending you that money for three times as long, so you pay interest for three times as long. That adds up.

The longer the tenure, the more interest you accumulate, even if the rate stays the same. A smaller monthly payment doesn’t always mean a cheaper loan.

Interest isn’t the only cost. Before you sign anything, check for these.

For both banks and licensed moneylenders:

• Processing fee — a one-time fee charged when your loan is approved, sometimes deducted directly from your loan amount. For licensed moneylenders, this is capped at a 10% admin fee.
• Late payment fee — charged if you miss or delay a repayment. For licensed moneylenders, this is capped by law at $60 per month.
• Early repayment fee — some banks charge you for paying off your loan ahead of schedule, since they lose out on future interest.

For licensed moneylenders: the law sets strict caps on what they can charge. Total interest cannot exceed 4% per month, and total fees and interest cannot push your debt beyond double the original loan amount. These are legal limits under the Moneylenders Act — we talk about this more in What licensed lenders can and cannot do.

For banks: fees vary by institution and aren’t subject to the same statutory caps, so it’s worth reading the fine print carefully.

A personal loan works well when you have a specific, one-time expense and a clear plan to repay.

Common reasons people take one out include covering medical costs, funding home renovations, managing a wedding, handling an emergency, or consolidating multiple debts into one simpler payment.

It’s less suited for ongoing or unpredictable expenses. If you’re not sure how much you’ll need, a personal loan’s fixed lump-sum structure can work against you.

If you’re still figuring out whether a loan is right for your situation, a good next step is understanding whether you’re likely to qualify before you apply.
