What is an HDB Loan?

An HDB loan is a government-backed home loan provided directly by the Housing & Development Board (HDB).

It’s not from a bank.

It’s specifically designed for Singaporeans purchasing public housing, and it’s especially helpful for first-timers, middle-income families, and anyone who wants a bit more predictability in their finances.

Who qualifies for an HDB Loan?

Before you can get your hands on an HDB loan, you’ll need to meet a few eligibility conditions.

Here’s a quick breakdown.

At least 1 applicant must be a Singapore Citizen. If you’re applying with a non-citizen spouse or family member, you’ll still be considered as long as you are Singaporean.
You must not have taken more than 1 HDB loan previously.
- You’re still eligible if this is your second HDB loan, but stricter rules will apply (more on this later).
- If you’ve already taken 2 or more HDB loans, you’re no longer eligible.
You must not own any other residential property at the time of applying – This includes:
- Private residential property (in Singapore or overseas)
- Commercial or industrial property that has residential components
  – If you’ve just sold a property, you need to wait 30 months before applying for an HDB loan.

Eligibility also depends on:

Income limits – These are based on your gross monthly household income, and they vary depending on who you’re applying with:
- Families: must earn $14,000/month or less
- Extended families (e.g. married siblings or parents with married children): $21,000/month or less
- Singles (under the Single Singapore Citizen Scheme): $7,000/month or less
Employment type – Whether you’re a full-timer, freelancer, or self-employed, you’ll need to provide supporting documents for income assessment (like payslips or IRAS notices).
Marital status and family nucleus – HDB loans are only given to those forming a valid family unit:
- Married couples
- Fiancés/fiancées (with proof of intention to marry)
- Singles aged 35 and above (under specific schemes)
- Families buying together (e.g. siblings, parents and children)
Type of flat you’re buying – Only new HDB flats or resale flats qualify. Executive Condos (ECs) and private properties are not eligible.
Credit assessment:
- For all types of employment and trade: applicants need to be working at the point of HFE letter application, have stable work, and regular income
- For applicants earning an income without monthly CPF contributions: have good credit standing

How much HDB loan can I take?

Your financial situation

This is the ability to sustain the payment of the monthly mortgage instalments, to ensure that there is no need to borrow beyond one’s means.

It is based on:

Age
Monthly income
Job stability
Current loans and financial commitments (e.g., credit card bills, car loans)
Past repayment records
Monthly cash savings

Repayment period

Capped at whichever is the shortest:

25 years;
65 years minus the average age of the applicants; or
Remaining lease of the flat minus 20 years

Loan-to-Value (LTV) Limit

The loan amount is up to 75% of the flat’s purchase price or market valuation – whichever is lower.

So, for example:

If your flat costs $500,000, but HDB values it at $480,000, your loan is capped at 75% of $480,000 → that’s $360,000.

This is known as the Loan-to-Value (LTV) limit.

Mortgage Servicing Ratio (MSR): 30% of your gross monthly income

This is HDB’s way of saying “don’t overstretch yourself”.

Your monthly repayments (including CPF and cash) must not exceed 30% of your gross income.
So if your household earns $6,000 a month, your monthly loan repayment can’t be more than $1,800.

This also means:

Even if you’re eligible for a big loan, you might not actually be able to borrow the full 75% – especially if your income is on the lower side.

Want to know your actual loan amount?

Use HDB’s Loan Calculator on the HDB Flat Portal to get a personalised estimate.

It factors in your income, loan tenure, and flat price.

What is the down payment requirement for an HDB Loan?

The down payment requirement for an HDB loan is 25% of the flat’s purchase price or valuation, whichever is lower.

You can use your CPF Ordinary Account (OA) savings to fully cover this amount, no cash required unless your CPF balance falls short.

This makes it more accessible for first-time buyers who may not have a large cash reserve saved up.

Compared to bank loans, which require at least 5% in cash, the HDB loan down payment option is generally more forgiving for homeowners starting out.

How is interest computed in an HDB housing loan?

Fixed Interest Rate

Unlike bank loans that often come with floating or promotional teaser rates, HDB loans offer a fixed interest rate.

This gives you predictability.

You’ll know exactly what you’re paying every month – no nasty surprises if market rates go up.

This makes it especially useful if you’re someone who prefers to play it safe or just wants a clear, consistent repayment plan.

Pegged to CPF Ordinary Account (OA) rate

The HDB loan interest rate isn’t just randomly decided, it’s pegged directly to the CPF OA interest rate.

The CPF OA rate is currently 2.5% per annum.
HDB adds a 0.1% buffer on top of that.

So, your HDB loan interest rate comes to a flat 2.6% per annum.

As mentioned, this rate has remained the same since 1999, so unless CPF decides to shake things up, it’s likely to stay that way for the foreseeable future.

Why does that matter to you?

It means your loan interest won’t jump unexpectedly unlike bank loans, which can shift every few months based on SORA (Singapore Overnight Rate Average) or other market indexes.

Monthly Rest Basis

HDB calculates interest using the monthly rest basis.

What does that mean?

It means your interest is charged only on the remaining loan amount and not the original loan you took.

And it’s calculated at the end of each month, not upfront.

So as you repay your loan month by month, the interest charged also goes down.

You’re not paying interest on money you’ve already returned.

Makes sense, right?

Here’s an example:

Let’s say your outstanding loan is $300,000.

After paying off $1,000 this month, your interest next month is based on $299,000 and so on.

This method is fairer and more transparent, and lets you see the impact of early or higher repayments.

If you make lump sum repayments, you’ll also save on future interest, since your remaining balance drops faster.

The formula for interest calculation

Alright, if you’re the kind who likes to see the maths behind things (or just want to double-check HDB’s numbers), here’s the actual formula they use:

Interest for the Month = Outstanding Loan Principal as at the 1st of the month × (Interest Rate ÷ 12)

Note: the interest rate in this calculation is per annum

Let’s break that down with a quick example:

Say your outstanding loan amount is $300,000
And the interest rate is 2.6% per annum

Your monthly interest would be:

$300,000 × (2.6% ÷ 12)

= $300,000 × 0.002167
= $650.10

So that’s $650.10 in interest for the month.

As your principal goes down, so does this amount.

Note: This doesn’t include your actual monthly repayment which would also include a portion that goes toward reducing your loan principal.

That’s why early repayments can save you a fair bit on total interest.

How can I apply for an HDB housing loan?

Applying for an HDB loan is way more straightforward than most people think.

You don’t have to fill in a ton of forms or make multiple trips to the HDB Hub; almost everything is done online now through the HDB Flat Portal.

Here’s what the process looks like:

Step 1: Apply for an HDB Flat Eligibility (HFE) letter

This is your starting point.

Head to the HDB Flat Portal and log in with your Singpass.
Select the option to take up a housing loan from HDB.
The portal will guide you through submitting your income documents and family details.

Your HFE letter confirms:

Whether you’re eligible for an HDB loan
How much you can borrow
Whether you qualify for housing grants
Your eligibility for BTO/resale flats

Without it, you won’t be able to book a flat or take up an HDB loan.

Step 2: Use the payment plan calculator

Before you commit to anything, it’s smart to know your numbers.

Use HDB’s budgeting tool to check how much you can afford.
This includes your estimated monthly repayments, cash/CPF split, and downpayment amounts.
It helps you decide whether you’re better off with a smaller flat or a longer loan tenure or maybe both.

Step 3: Wait for the HFE outcome

Once approved, your HFE letter will be valid for 9 months.

That gives you time to:

Book a BTO flat during sales exercises
Shop for a resale flat
Compare loan options (yes, including banks – we’ll get to that!)

In a nutshell: apply for the HFE letter, use the budgeting tools, and wait for your loan eligibility and grant info to come in.

How to pay your monthly HDB loan instalments

You’ve got a few options, whether you prefer using CPF, cash, or just want to automate everything through GIRO.

1. CPF Ordinary Account (OA)

If you’re a flat owner, you can use your CPF OA savings to pay for your monthly instalments. In fact, this is how most Singaporeans do it.

You can pay in full via CPF, or split the payment with cash.
Want to keep some money in your CPF for rainy days? You’re allowed to retain up to $20,000 in your OA.
You can also:
- Make ad hoc payments using CPF (e.g. top-ups or lump-sum repayments)
- Adjust your CPF contribution rate for the loan instalments anytime

2. GIRO Payment

This is the most convenient option if you’re paying by cash.

Simply set up GIRO with your bank so the monthly instalment is deducted automatically.

It’s a one-time setup and ensures you’ll never forget a payment (no reminders needed).

However, just make sure your account has enough funds a few days before deduction as GIRO rejections can come with a $5 admin fee.

3. e-Payments and Cash Options

Prefer to make manual payments?

No problem.

You can pay your instalment:

At HDB Branch Offices
Through AXS Stations (just look under “HDB” in the services list)
Using e-payment options like PayNow via the HDB Flat Portal

This is handy if you want to make partial payments or test a new payment mode before committing to automation.

4. Internet Banking

If you’re using internet banking, you can log in to your bank’s website or app and set up HDB as a billing organisation.

Key in your loan reference number
Choose how much you want to pay
Schedule payments ahead of time if you like

Just note: not every bank supports this in the same way, so check your bank’s FAQ or HDB’s instructions if you’re unsure.

How can I check my outstanding housing loan?

Here are the 2 ways you can do it:

1. Check online via HDB’s website

This is the fastest and easiest way.

Head to the HDB website and log in with your Singpass.
Navigate to: My Flat > Purchase Flat > Financial Info

You’ll be able to see:

Your outstanding loan amount
The interest charged
Your monthly instalment
Any early repayment options

Pro tip: Do this every once in a while so you know where you stand.

You’ll also see if you’re on track to finish up early or if you need to make any adjustments.

2. Visit the HDB Branch handling your flat

Prefer to speak to a human being?

No problem.

You can schedule an appointment using the HDB e-Appointment system
Once there, the staff can walk you through your loan details, repayment plans, and even help you process early repayments if needed

Just remember – walk-ins aren’t accepted, so always book in advance.

Knowing your loan balance helps you make smarter decisions – whether you’re thinking of refinancing, budgeting for home reno, or even just trying to be mortgage-free sooner.

Can I make early repayment for my HDB loan?

Yes, and unlike many bank loans, there’s no penalty if you want to pay off your HDB loan early.

How to make early repayments

You’ve got 2 options:

Online via the HDB Flat Portal: Just log in with your Singpass and head to the financial section under ‘My Flat’. You’ll see options for:
- One-time lump sum payments
- Ad hoc CPF payments
- Adjusting your monthly instalment amounts
In person at your HDB Branch Office: If you prefer face-to-face help, you can book an appointment via e-Appointment. The officers can guide you through the repayment process and even help you revise your plan on the spot.

Tip: Early repayment means paying less interest over time, since HDB uses the monthly rest basis, so the sooner you reduce your principal, the less you pay in interest.

Also take note that you’ll have to repay the accrued interest even after finishing paying your loan.

This means that you still have to pay, after you’ve finished paying.

Confusing? Yes. Read this post to understand it better.

Want to change your repayment period?

You can do that too.

Extending your loan tenure = smaller monthly instalments (more breathing room, but you pay more interest over time)
Shortening your loan tenure = higher monthly instalments (faster payoff, less interest)

This flexibility can be a game-changer if your income situation changes, or if you’re planning for big life milestones like having a kid, switching jobs, or retiring early.

So yes, early repayment is not only allowed, it’s encouraged if your finances allow it.

And with no penalties involved, you’re free to tweak your plan however you see fit.

The benefits of an HDB Loan

Here’s why an HDB loan could be the better choice:

1. Fixed interest rate at 2.6% p.a.

This rate is pegged at 0.1% above the CPF OA interest rate, which is currently 2.5%.

The result? A stable 2.6% rate that hasn’t changed in over 2 decades.

It’s especially great when bank interest rates shoot up like what we’ve seen recently with global inflation.

Of course, if bank rates fall to 1.5% or lower, you could end up paying more with HDB – but that’s the trade-off for long-term stability.

2. No lock-in period

You’re not tied to your HDB loan. At all.

You can refinance to a bank loan anytime if you spot a better deal later.

There are no penalties, no exit fees, and no gimmicks. Total freedom.

But take note, once refinanced to a bank loan, you can’t switch back. So switch with caution.

3. Higher Loan-to-Value (LTV) ratio of up to 75%

You can borrow up to 75% of your flat’s purchase price (or market valuation – whichever is lower).

For comparison, some bank loans might offer slightly less if your credit profile isn’t ideal.

This means a lower upfront downpayment, which is great if you want to keep more cash on hand.

4. Early repayment is allowed – no penalties

Whether it’s a full lump-sum payment or just a bit extra every month, HDB doesn’t charge you for paying early.

So if you get a bonus, inheritance, or just want to be mortgage-free sooner, you’re free to do so.

Plus, you can tweak your monthly instalments anytime if your income or goals change.

In short, if you’re looking for something that’s reliable, easy to manage, and gives you financial flexibility, the HDB loan is hard to beat especially if you’re not a fan of risk or surprises.

Is there an alternative to HDB loans?

Yes, while HDB loans offer stability and government backing, they’re not the only option out there.

For some homeowners, especially those with a higher income or appetite for flexibility, bank loans may be a better fit.

We cover all about this here and cover the advantages and disadvantages of a bank loan here.

When is a bank loan a better option?

While HDB loans offer stability and flexibility, bank loans can sometimes give you more savings and control if you know what you’re doing.

Here’s when a bank loan might be the smarter choice:

When interest rates are low, and you’re confident they’ll stay that way for a few years
(especially useful if you’re opting for a fixed-rate package)
When you want to restructure your loan down the road, bank loans often give you refinancing options across different lenders (think of it like switching telcos to get a better deal, but for your mortgage)
If you’re planning to sell or upgrade in a few years, a lower short-term rate could mean more savings before you exit

Important reminder: Once you switch from an HDB loan to a bank loan, you can’t go back. It’s a one-way street – so weigh your decision carefully.

Frequently Asked Questions

What happens to my HDB Loan if I sell my flat?

If you sell your flat, your HDB loan will need to be fully paid off using the sale proceeds.

The outstanding loan amount is typically settled during the completion of the sale, so you won’t need to manually clear it beforehand.

Any remaining proceeds after repaying the loan will go back to your CPF Ordinary Account (if CPF was used), followed by cash to you.

Just make sure the sale price covers your outstanding loan if not, you’ll need to top up the shortfall in cash.

What happens if I can’t repay my HDB Loan?

If you can’t repay your HDB loan, things can get serious, but there are steps you can take before it gets out of hand.

HDB will typically reach out first and may allow you to reschedule your loan, reduce your monthly instalments, or extend your loan tenure temporarily.

If repayments continue to be missed, you risk late payment charges, and in extreme cases, HDB may repossess your flat.

So if you’re struggling to repay your HDB loan, it’s crucial to contact HDB early; they’re more likely to help if you’re proactive.

Conclusion

And there you have it, everything you need to know about HDB loans, from how they work to whether they’re the right fit for you.

We’ve covered the basics of what an HDB loan is, who qualifies, how much you can borrow, and even how it stacks up against bank loan options.

Whether you’re all about predictable monthly repayments or eyeing lower rates with a bank, the key is to make a decision that works for your lifestyle and long-term goals.
