Should you pay off your mortgage or invest first? In Singapore in 2026, the honest answer starts with a number most older comparisons never had to deal with: mortgage rates have fallen far below where they sat when the standard advice was written. Bank loan packages were going for about 1.3% to 1.5% a year as of June 2026, while CPF's Special, MediSave and Retirement Accounts still guarantee 4% a year through to the end of 2026, and the Ordinary Account guarantees 2.5%. A growing number of homeowners are now paying less interest on their loan than they could earn just leaving money inside CPF, before a single dollar goes near the stock market. This piece works through the real 2026 numbers, a CPF Ordinary Account catch that most guides skip, and exactly who should still prioritise paying down debt first.
The classic framing of this decision is simple. Paying down your mortgage gives you a guaranteed return equal to your loan's interest rate. Investing gives you an uncertain, historically higher return. Whichever number is bigger, after you weigh in how much uncertainty you can stomach, wins.
The number that changed is the mortgage rate itself. As at June 2026, the cheapest floating home loan packages for private property were quoted from about 1.27% a year, led by HSBC and Maybank pricing off 3-month compounded SORA plus a 0.20% spread, with fixed packages available from about 1.40% to 1.45% a year at HSBC, Citi, DBS and Maybank. That reflects a sharp fall in the benchmark rate itself: 3-month compounded SORA dropped from a peak near 3% in early 2025 to roughly 1.06% by June 2026. HDB's own concessionary loan rate, pegged at 0.1% above the CPF Ordinary Account rate, has stayed at 2.6% for most of the past two decades.
Set those against CPF's guarantees. The Ordinary Account pays a legislated floor of 2.5% a year, unchanged through the third quarter of 2026. Special, MediSave and Retirement Account savings pay a floor of 4% a year, which the government has extended through 31 December 2026. Put the two side by side: someone on one of 2026's cheapest floating packages is paying less interest on their home loan than CPF pays them just for holding cash. That is not a small footnote. It is the opposite of the environment that produced the 3.5%-to-4.5%-mortgage examples in most existing guides on this topic, and it changes which side of the ledger looks better by default.
None of this means investing is risk-free or that a low mortgage rate is a reason to relax. It means the starting comparison in 2026 usually runs mortgage rate versus CPF's own guaranteed rate first, and only then against the stock market.
Using CPF Ordinary Account money to service or prepay an HDB or bank loan feels like using cash you already have. It is not quite that simple. When you eventually sell the property, CPF requires you to refund the principal amount you withdrew from your Ordinary Account, plus the interest that money would have earned had it stayed in CPF, currently 2.5% a year, compounded for every year it was out.
Run the arithmetic on a plausible case: a homeowner draws down S$50,000 of Ordinary Account savings over the years to help pay off a loan. At a 2.5% annual accrual, that refund obligation grows to roughly S$64,000 after 10 years, before the property is even sold. The CPF Ordinary Account money did real work reducing the loan balance, but it was never a free discount. It behaves like a loan from your own retirement savings, carrying an implicit 2.5% cost that only becomes visible at the point of sale.
That single mechanic is why using CPF Ordinary Account for a low-rate loan deserves a second look. If your bank package costs 1.3% and the CPF refund obligation accrues at 2.5%, redirecting Ordinary Account money at your mortgage is, in effect, swapping a 1.3% liability for a 2.5% one. The CPF Ordinary Account rules make this refund automatic on sale, so it is worth checking your own CPF statement for how much has already been withdrawn before assuming extra CPF-funded prepayment is doing you a favour.
For a market benchmark, use a fund with a real, published track record rather than a generic portfolio number. The SPDR Straits Times Index ETF, Singapore's oldest local equity ETF, has returned an annualised 10.05% net of fees over the 10 years to 31 May 2026, and 8.12% a year since it launched in April 2002, according to State Street's own fund factsheet. Those figures are net of a 0.28% expense ratio and include reinvested distributions. They are historical averages, not a smooth ride. The same 10 years included sharp single-year drawdowns, and a decade that averaged 10% did not deliver 10% in every year along the way.
Here is what that gap looks like in practice. Take a homeowner with S$500 a month in spare cash and a bank loan priced at 1.35% a year, roughly the midpoint of June 2026's floating packages. Directed at extra mortgage repayment for 10 years, that S$500 a month saves about S$4,200 in interest, for an effective ending value of roughly S$64,200 against S$60,000 of principal put in. Directed instead into an ETF tracking the STI at its 10-year annualised 10.05%, the same S$500 a month would be worth roughly S$100,200 after 10 years, a gap of about S$36,000. Every number after the mortgage rate in that comparison depends on the market repeating its own past average, which is not guaranteed.
The gap narrows sharply for one specific kind of investor: someone who checks portfolio values often and is likely to sell during a downturn. Selling into a 20% drawdown locks in the loss rather than riding out the recovery, and the realistic return for that behaviour pattern is well below the historical 10%. For that person, the guaranteed, if smaller, return from paying down the loan is the better real-world outcome, not just the more comfortable one. Our fixed deposit vs investing calculator lets you run your own numbers against a specific mortgage rate instead of relying on the averages above.
The HDB loan and bank loan rows above are not interchangeable. If you refinanced out of HDB into a bank loan years ago and never revisited it, our HDB loan vs bank loan guide and the fixed vs floating mortgage comparison are the next things worth reading before you decide anything from this table.
| Your situation | 2026 context | Likely better move |
|---|---|---|
| HDB concessionary loan at 2.6% p.a. | Below CPF SA/RA's 4% floor and near long-run market averages | Keep the minimum repayment; route spare cash to CPF top-ups, SRS or an ETF |
| Bank loan, floating, ~1.3%-1.5% p.a. (2026 lows) | Below even CPF OA's 2.5% floor | Extra repayment rarely beats CPF top-ups or investing on rate alone |
| Bank loan, fixed, locked in during the 2023-2025 high-rate window | Rate likely still above CPF SA/RA's 4% floor | Compare refinancing to a 2026 package against extra repayment |
| No 3-6 months of expenses saved yet | Applies regardless of your loan rate | Build the emergency buffer before extra repayment or investing |
| Near your MSR or TDSR ceiling, or refinancing within 12 months | Applies regardless of your loan rate | Prioritise repayment headroom and lock-in timing over rate optimisation |
The rate gap does not erase every reason to prioritise the loan. Retirees and near-retirees drawing on CPF LIFE payouts or a fixed retirement income have less capacity to absorb a market drawdown and more to gain from cutting a monthly obligation, so the smaller guaranteed return from clearing debt usually outweighs a historically higher but uncertain investment return at that stage of life.
Anyone still sitting on a fixed-rate package locked in during the 2023-to-2025 high-rate window, likely priced above 3.5% to 4% a year, is in a different position from someone on a fresh 2026 floating loan. For that borrower, the first move is checking whether refinancing to a current package beats both extra repayment and doing nothing, not choosing between repayment and investing on the old rate.
Households sitting close to their Mortgage Servicing Ratio or Total Debt Servicing Ratio ceiling, or who know a refinancing decision is coming within the next year, gain more from preserving repayment headroom and a stronger negotiating position with the bank than from chasing a small rate spread either way.
Put in a specific order rather than a single verdict, the 2026 numbers suggest working through spare cash roughly like this before locking in a split between repayment and investing.
With floating mortgage rates from about 1.3% a year and CPF's Special and Retirement Accounts guaranteeing 4% a year through to the end of 2026, most homeowners on a cheap 2026 package come out ahead putting spare cash into CPF top-ups, SRS or a diversified investment rather than extra mortgage repayment. The exception is anyone still on an older loan priced above roughly 4% a year, or without a 3-6 month emergency fund in place.
Not automatically. CPF Ordinary Account money used for your mortgage must be refunded, principal plus the 2.5% a year it would have earned, when you sell the property. That refund obligation means using Ordinary Account savings is not a free discount; it behaves like a loan from your own retirement savings at an implicit 2.5% cost, under CPF Board's accrued-interest rules.
There is no single official cutoff, but the SPDR Straits Times Index ETF's own 10-year annualised return of 10.05% to May 2026 is a useful benchmark. A mortgage priced well below that, which describes most 2026 floating packages under 1.5%, leaves a wide gap in investing's favour, even after accounting for the fact that equity returns are historical averages, not guaranteed the way loan interest savings are.
Bank loans typically carry a lock-in period of two to three years, during which full or partial early repayment triggers a penalty of roughly 0.75% to 1.5% of the amount repaid; outside the lock-in, most banks allow prepayment for free, subject to a minimum amount that is commonly S$5,000 to S$10,000 depending on the bank. HDB loans do not carry the same commercial penalty structure, but always confirm the current terms on your own loan before redeeming early.
Generally yes. Someone drawing down CPF LIFE payouts or living on a fixed retirement income has less capacity to ride out a market drawdown and more to gain from removing a monthly repayment obligation, so the guaranteed, if smaller, return from clearing the loan usually outweighs a historically higher but uncertain investment return at that stage of life.
