Most people asking about moneylender interest rates in Singapore are really asking two questions at once. Is this charge legal? And is this a fair deal? The law answers the first one precisely. It leaves the second to you.
Under the Moneylenders Act and the Moneylenders Rules, there is a closed list of charges a licensed moneylender may impose on an individual borrower, and every item on it has a cap. Anything outside that list has no legal basis, whatever the contract in front of you says.
This guide sets out each cap as of August 2026, works through what they mean on a S$5,000 loan, and gives you a sequence for checking a quote line by line.
What is the maximum interest a licensed moneylender can charge?
Licensed moneylenders in Singapore can charge a maximum of 4% interest per month. As of August 2026, that ceiling applies regardless of your income and regardless of whether the loan is secured or unsecured. It has been in force since 1 October 2015. Interest is calculated on the principal still outstanding after your repayments, not on the amount you originally borrowed.
The reducing balance part is where most of the confusion sits, so there is a full calculation further down.
What other charges are allowed, and what are their limits?
Four charges are permitted alongside interest, and the list is closed. As of August 2026, the following is everything a licensed moneylender in Singapore may charge an individual borrower:
| Charge | Legal maximum | How it applies |
|---|---|---|
| Interest | 4% per month | On the principal remaining after repayments |
| Late interest | 4% per month | Only on the amount actually overdue |
| Late fee | S$60 per month of late repayment | Per month late, not per missed instalment |
| Administrative fee | 10% of the principal | One-time, when the loan is granted |
| Legal costs | As ordered by court | Only after a successful recovery claim |
Read the late interest row closely, because it is routinely misunderstood. Miss one instalment and late interest applies to that overdue instalment alone. The rest of your balance, still within its due date, cannot attract it.
The late fee works on a similar logic but a different unit. It is capped at S$60 for each month a repayment is late. Two missed instalments inside the same month do not double it.
Can the total cost of a loan ever exceed what you borrowed?
No. As of August 2026, interest, late interest, the administrative fee and late fees combined can never exceed the principal you borrowed from a licensed moneylender in Singapore. However long the loan runs, and however badly repayment goes, that ceiling holds.
On a S$5,000 loan:
- Principal borrowed: S$5,000
- Total charges permitted across the life of the loan: S$5,000
- Most you could ever repay in total: S$10,000
One detail that often gets missed: the administrative fee counts towards that allowance rather than sitting on top of it. At the maximum 10%, S$500 is consumed the moment the loan is granted, leaving S$4,500 for all interest and late charges combined.
How does 4% per month work out on an actual loan?
On a S$5,000 loan cleared over five months, 4% per month on the reducing balance comes to S$600 in total interest. Here is the whole calculation, using S$1,000 of principal repaid each month to keep it easy to follow:
| Month | Principal at start | Interest at 4% | Principal repaid |
|---|---|---|---|
| 1 | S$5,000 | S$200 | S$1,000 |
| 2 | S$4,000 | S$160 | S$1,000 |
| 3 | S$3,000 | S$120 | S$1,000 |
| 4 | S$2,000 | S$80 | S$1,000 |
| 5 | S$1,000 | S$40 | S$1,000 |
| Total | — | S$600 | S$5,000 |
Charged flat on the original S$5,000 across the same five months, that identical 4% would produce S$1,000. The reducing balance method costs S$400 less here. Same headline rate, different method, materially different total.
This is deliberately the simplest possible structure so the arithmetic stays visible. Real instalment schedules distribute principal and interest differently, and a longer tenure changes the total even at the same rate. Our loan calculator will model your own figures, and monthly loan 101 explains how principal, tenure and EIR interact.
Now set this loan against the total cost cap. S$600 of interest plus a maximum administrative fee of S$500 comes to S$1,100 in charges on a S$5,000 loan repaid on schedule, against a ceiling of S$5,000. Nowhere close.
That gap is the honest picture of what the cap is for. It is not what sets your cost on a loan that goes normally. It is what stops a loan from compounding out of reach when something goes wrong, which is a different and narrower kind of protection than most summaries imply.
What must a licensed moneylender do, and what can they never ask for?
A licensed moneylender’s obligations to you run for the life of the loan, not just at signing. As of August 2026, a licensed moneylender in Singapore must:
- Explain the contract terms in a language you understand
- Give you a copy of the Note of Contract
- Issue receipts for your repayments
- Provide statements of account at least every January and July
Two things a licensed moneylender may never do. It may not retain your NRIC or other identity documents. It may not ask for your Singpass login credentials.
Neither of those is a judgement call or a matter of internal policy. If either one happens, you are not dealing with a lender working inside the rules.
How do you check a loan quote against the legal caps?
Work through the paperwork in this order.
- Confirm the lender is licensed. Check MinLaw’s list of licensed moneylenders in Singapore. If the business is not on that list, none of the caps in this article protect you, and nothing further on this checklist is worth doing.
- Check the monthly interest rate against the 4% ceiling.
- Match every charge in the quote to the permitted list above. Query anything that does not map onto it.
- Check the administrative fee against 10% of the principal.
- Total the worst case — all interest, plus every late charge that could apply, plus the administrative fee — and confirm it cannot exceed the principal.
- Read the Note of Contract in full before you commit. Our guide on how to read a loan agreement in Singapore goes through it clause by clause, and there are specific questions worth putting to any lender before signing.
A familiar situation shows why the sequence matters. A couple collect the keys to their BTO flat, the contractor’s final quote comes in above the renovation loan they arranged with their bank, and they need S$5,000 to close the gap before work starts. Under time pressure, the temptation is to scan the quote for the monthly instalment and sign.
Step 1 tells them whether any of these caps apply. Steps 3 and 4 tell them whether the charges in front of them are permitted ones at permitted levels. Step 5 tells them the ceiling on their worst case before they commit to anything. None of it needs financial training. It needs the list above and ten unhurried minutes.
One question this article does not answer: how much you are allowed to borrow. That runs on separate caps which vary with income and residency status, and which are checked across all licensed moneylenders through the Moneylenders Credit Bureau when you apply. What a lender may charge and what you may borrow are two different rules.
Where do these limits come from, and how can you verify them?
Every figure above comes from the Registry of Moneylenders, which sits under the Ministry of Law. Licensed moneylenders in Singapore are regulated by the Registry of Moneylenders, not by the Monetary Authority of Singapore. That distinction is practical rather than pedantic: MAS material will not tell you what a licensed moneylender may charge, and a site claiming MAS regulation of moneylending has its facts wrong.
You can check all of it at source:

These caps do change. The 4% ceiling itself dates from a 2015 revision. Every figure here is stated as of August 2026, and this page carries a visible updated date so you can see how current it is.

Yes. As of August 2026, 4% per month is the maximum interest a licensed moneylender in Singapore may charge, in force since 1 October 2015. The cap applies regardless of income and to both secured and unsecured loans. Interest is calculated on the principal remaining after repayments.
Can the total charges on a loan exceed the amount I borrowed?
No. As of August 2026, interest, late interest, the administrative fee and late fees combined can never exceed the principal borrowed from a licensed moneylender in Singapore. Borrow S$5,000 and total charges are capped at S$5,000, no matter how long repayment takes.
What is the maximum late fee a licensed moneylender can charge?
As of August 2026, licensed moneylenders in Singapore may charge up to S$60 for each month a repayment is late. This is per month late, not per missed instalment, so two missed payments within one month do not double it. Late interest of up to 4% per month may also apply.
Is late interest charged on my whole outstanding balance?
No. As of August 2026, licensed moneylenders in Singapore may charge late interest only on the amount actually overdue. Any balance still within its due date cannot attract late interest. The late interest cap is 4% per month, the same ceiling that applies to ordinary interest.
Can a licensed moneylender charge a fee upfront?
Yes. As of August 2026, a one-time administrative fee of up to 10% of the principal may be charged when the loan is granted. On a S$5,000 loan that is a maximum of S$500, and it counts towards the total cost cap rather than sitting outside it.
Are licensed moneylenders regulated by MAS?
No. Licensed moneylenders in Singapore are regulated by the Registry of Moneylenders under the Ministry of Law, not the Monetary Authority of Singapore. You can verify any moneylender’s licence on MinLaw’s list of licensed moneylenders before applying.
