If you are choosing between a fixed and a floating rate for a Singapore home loan, the short answer is this: floating (SORA-pegged) packages are usually cheaper today, fixed packages buy you a predictable instalment for a limited time, and the right choice depends on how much of a rise in your monthly payment you can absorb, not on guessing where rates go next.
This guide explains how each type works in Singapore, what current rates look like, how to stress-test your own budget, and where the HDB concessionary loan fits in.
TL;DR
- Floating-rate packages are pegged to compounded SORA and currently start well below the HDB concessionary rate of 2.6% p.a. For HDB flats, bank floating rates start from about 1.54% (October 2026).
- A fixed rate locks your rate for a set period, typically 1 to 3 years, in exchange for a likely higher starting rate. It then reverts to a floating rate.
- Whichever you pick, banks must test whether you can afford the loan at a 4% interest rate floor, so your approval does not depend on the package type.
- Choose fixed if a stable instalment matters most. Choose floating if you have room in your budget for the payment to rise.
- Your lock-in period, repricing terms and early repayment penalties matter as much as the headline rate.

What the two rate types mean in Singapore
A floating-rate package moves with a benchmark. In Singapore, that benchmark is mostly the Singapore Overnight Rate Average (SORA), which MAS describes as the volume-weighted average rate of unsecured overnight interbank SGD borrowing. Banks usually peg your loan to the 1-month or 3-month compounded SORA and add a spread. A package quoted as “3M SORA + 0.30%” means your rate is the 3-month compounded SORA plus 0.30 percentage points, reset at the interval stated in your letter of offer.
A fixed-rate package holds your interest rate constant for an initial period. Singapore banks generally fix only the early years, not the full tenure. After that, the loan reverts to a floating rate. So “fixed” in Singapore really means “fixed for now”.
The CPF Board’s guidance frames the trade-off well. A floating rate can save you money if market rates stay low but raises your repayments if they climb. A fixed rate protects you from that volatility for a set period, usually 1 to 3 years, at the cost of a likely higher initial rate.
There is also a third product that is neither: the HDB concessionary loan. We cover it below, because for many flat owners it changes the question.
Where rates stand in October 2026
Rates have come down a long way from the peak. MAS’s Financial Stability Review notes that domestic interest rates eased substantially over the past year, with the 3-month compounded SORA roughly halving to around 1.1% by the second quarter of 2026.
For HDB flats, CPF Board’s comparison shows the HDB concessionary rate fixed at 2.6% p.a., while bank floating packages for HDB loans start from around 1.54% (3M SORA + 0.30%). That is a gap of more than a full percentage point.
Two cautions apply to any rate you see quoted online:
- Advertised “from” rates are the lowest in the market, and your own rate depends on the loan size, property type, completion status and your profile.
- Many banks reprice their fixed packages more often than their floating spreads, so a fixed rate quoted last month may not be on offer today.
Check the current rate sheet with the bank or ask us for a side-by-side before you commit.
How SORA actually moves your instalment
It is tempting to assume that every US Federal Reserve move flows straight into your mortgage. It does not work that way. CNA’s explainer points out that Singapore mortgage rates are shaped by domestic liquidity, local interbank competition and funding costs, so SORA-pegged loans may not adjust immediately or by the same amount as the Fed.
That helps in both directions. Floating borrowers are not whipsawed by every headline. But you also cannot count on rates falling just because the Fed eases.
The lag also depends on which SORA you are pegged to. A 1-month compounded SORA package reprices more often and reacts faster. A 3-month package is steadier. If you want to understand the difference, our walkthrough on comparing SORA and SIBOR explains the benchmarks that still show up in older loans.
What a rate change does to your monthly payment
To make this concrete, here is an illustration for a S$800,000 loan over 25 years. These are our own calculations using standard amortisation, not a bank quote, and they ignore any spread changes or repricing dates.
| Interest rate | Approx. monthly instalment | Change vs 1.5% |
|---|---|---|
| 1.5% | S$3,200 | n/a |
| 2.5% | S$3,590 | about +S$390 |
| 3.5% | S$4,000 | about +S$800 |
| 4.0% | S$4,220 | about +S$1,020 |
A rise of two percentage points adds around S$800 a month on this loan. If that number makes you wince, a fixed package for the first few years, or a larger buffer in your budget, deserves serious thought. If you could absorb it without touching your savings or your lifestyle, floating is easier to justify.
The table also shows why a loan of this size is more sensitive than a smaller one. MAS’s Financial Stability Review carries analyst commentary, including from OCBC Research, that a prolonged period of elevated rates keeps pressure on households, particularly those with large outstanding loans.
Why the 4% stress test applies to both
Some buyers think a fixed rate gets them a lighter affordability check. It does not. MAS requires financial institutions to assess affordability using an interest rate floor of 4% for both private and HDB property loans, as part of the Total Debt Servicing Ratio (TDSR) calculation. The same MAS page sets out the other limits on borrowing, so read it before you plan a purchase.
The practical consequence: your borrowing power is set by the stress rate, not by the package you pick. The package choice then determines what you really pay each month. Our piece on how MAS interest rate floors affect borrowing capacity walks through the arithmetic.
Fixed vs floating: a side-by-side
| Criterion | Fixed rate | Floating rate (SORA-pegged) |
|---|---|---|
| Starting rate | Often higher | Often lower in the current market |
| Payment certainty | Stable for the fixed period | Can change at each repricing |
| After the initial period | Reverts to floating | Continues to follow the benchmark |
| Best for | Tight budgets, first-time buyers, those who dislike surprises | Buyers with spare cash flow, shorter holding periods |
| Main risk | Paying more than needed if rates fall | Instalments rising if rates climb |
| Watch out for | Lock-in and early repayment charges | Spread, repricing frequency, lock-in |
Neither is “better” in the abstract. Floating suits borrowers who can ride out movement. Fixed suits those who value certainty over the last bit of savings.
The questions that decide it
How much of a rise can your budget take?
Start with your current instalment, then add the amount from the table above for a two-point rise. If your household can pay that without cutting into emergency savings, floating is a reasonable choice. If not, fixed gives you a few years of certainty, and time to grow income.
How long will you hold the property?
If you plan to sell or refinance within two to three years, a fixed package that matches your horizon can work well. But check the lock-in and early repayment terms first. Our note on the 1.5% early redemption fee shows how a penalty can wipe out the savings from a lower rate.
Is your income stable?
Salaried, with predictable bonuses, you have more room to take floating risk. Commission-based, a business owner or approaching retirement, you may value the predictable payment of a fixed rate more, even if it costs a little extra.
Will you refinance?
Many Singapore owners refinance when their lock-in ends. If you are prepared to review your loan every couple of years, floating packages cost you little in flexibility. Read our guide to refinancing strategies in high and low rate environments and the overview of mortgage refinancing options in Singapore.
The HDB loan: a fixed rate with unusual flexibility
If you are buying an HDB flat, the HDB concessionary loan is the benchmark everything else is measured against. According to CPF Board, it is fixed at 2.6% p.a., pegged at 0.1 percentage point above the CPF Ordinary Account rate. It has no lock-in period and no early repayment penalty, and you can refinance to a bank loan at any time if market rates fall significantly.
The catch is one-way. Once you move from an HDB loan to a bank loan, you cannot switch back to the HDB concessionary loan for that property.
So the decision is really this: accept a rate that is currently well above the cheapest bank floating packages in exchange for stability and the option to leave, or take the lower bank rate now and give up the way back. Our five-step HDB vs bank loan guide works through it with 2026 rates.
Our perspective
We advise buyers on a lot of purchases, from new launches to resale and commercial units, and we see the same mistake repeatedly: people choose a rate before they have decided how long they will hold the property.
Here is how we think about it.
- Start with the exit. A buyer who plans to hold a new launch until TOP and then rent it out has a different risk window from a family settling in for ten years. The loan structure should follow the plan, not the other way round.
- Treat the stress test as your real ceiling. Even if today’s floating rate is low, we ask clients whether the household would be comfortable if payments moved toward the 4% level banks test at. If the honest answer is no, we steer toward more certainty or a smaller loan.
- Read the fine print, not just the headline. Lock-in, repricing frequency, legal and valuation subsidies and early repayment charges can swing the true cost by more than the difference between two quoted rates.
- Do not try to time the market. Nobody, including bank economists, reliably predicts the path of SORA. Build a plan that works across a range of outcomes.
For new launch buyers in particular, progress payments mean the loan is drawn gradually, so the effective cost builds over time. We looked at that in detail in our article on fixed vs floating home loans for new launch buyers in late 2026.

A simple way to decide
Use these steps before you speak to a bank.
- Write down your holding period. Under three years, three to five years, or longer.
- Calculate your stress budget. Take your loan amount and work out the instalment at 3.5% and at 4%. Can you pay it for a year without borrowing?
- Rank what matters most. Lowest cost today, or certainty of payment?
- Compare the full package. Ask each bank for the rate in years one, two and three, the lock-in, the early repayment fee, the subsidies, and the conditions for switching.
- Set a review date. Diarise a review six months before your lock-in ends so you can refinance or reprice without a rushed decision.
If your answers point both ways, a common middle path is to take the lower floating rate while keeping a cash buffer equal to several months of the higher instalment. Another is a shorter fixed period, so you are not locked for long. Whatever you choose, keep an eye on the wider picture in our summary of mortgage rates Singapore buyers should watch.
Common mistakes to avoid
- Chasing the lowest headline rate. A rate that is 0.1 percentage point lower is no use if a strict lock-in stops you from refinancing later.
- Ignoring LTV and cash needs. The size of the loan you can get affects how much cash and CPF you need upfront. See our explainer on loan-to-value limits for residential purchases.
- Assuming the fixed rate is permanent. It reverts to floating, so plan for the rate after the fixed period ends.
- Forgetting the valuation. If the bank values the property below the price, you may face a cash gap. Our article on low valuations and HDB deadlines explains how to prepare.
Getting help with the decision
The loan is only one part of a property purchase. At Aesthetic Havens, we help buyers and investors match the property, the budget and the financing plan, from new launches to resale, commercial and international purchases. If you would like a second opinion on your numbers before you commit to a package, get in touch with our consultancy team. We are not a bank, so we will help you frame the questions and compare the terms, but the final loan offer always comes from the lender.
FAQ
Is floating or fixed better for a Singapore home loan?
Neither wins in every case. Floating packages are cheaper at the moment, so they suit borrowers with room in their budget for the instalment to rise. Fixed packages suit those who value a stable payment for the first few years.
Will mortgage rates in Singapore fall further?
No one can say for certain. Local rates follow major economies but are also shaped by domestic liquidity and bank funding costs, so they do not mirror the Fed one for one. Plan for a range of outcomes rather than relying on a forecast.
Can I switch from a fixed to a floating loan later?
Usually yes, but check your lock-in period first. Switching or refinancing inside it can trigger an early repayment fee. If you are on an HDB loan, you can move to a bank loan at any time with no penalty, but you cannot move back.
Does the stress test change if I choose a fixed rate?
No. MAS requires lenders to assess affordability at a 4% floor for both private and HDB property loans, whatever package you choose. Your borrowing limit is therefore the same, though your actual payment will differ.
