Your Mortgage Costs 1.40%. The Loan for Your Kitchen Costs 5.96%.

The cheapest secured borrowing in more than a decade is sitting on the same property as some of the most expensive unsecured borrowing most households will ever take. A two-year fixed home loan is advertised at 1.40%. The renovation loan you sign three weeks later, for the kitchen in the same flat, carries a published effective rate of 5.96%.

That gap is not a scandal, and the banks are not hiding it — DBS prints both numbers on the same page. But almost nobody reads the second number, and the reason the two differ is not the reason most people assume.

The gap is fees, not a flat rate

A widely repeated claim is that renovation loans are quoted as flat rates — interest charged on the original sum for the whole term, which roughly doubles the true cost. Run the numbers and that claim does not survive.

DBS and POSB advertise 4.88% p.a., EIR 5.96%, with the footnote that the effective rate is "based on 60-months loan tenure and inclusive of 2% handling fee and 1% insurance premium" (DBS). If 4.88% were a flat rate, S$30,000 over five years would carry S$7,320 of interest and land nearer 10%. On a monthly-rest basis it carries S$3,869, and adding 3% of fees produces something very close to the published 5.96%. OCBC's own terms confirm the same convention, stating that interest is "calculated on a monthly rest basis, on the amount outstanding." These are reducing-balance loans.

So the real story is the 3% taken off the top. Approve S$30,000 and the bank deducts a 2% handling fee and a 1% insurance premium before disbursing; DBS's own worked example approves S$10,000 and disburses S$9,700. You repay interest on the full S$30,000. You received S$29,100.

Reconstructing the effective rate on that basis — S$29,100 received, sixty payments of S$564.49 — gives 6.14%, a little above the bank's published 5.96%. The difference is a matter of EIR convention rather than a dispute about the money; the cash flows above are the ones that hit your account either way.

Repaying early makes it worse

Here is the part that catches people. The 3% is a percentage of the principal, not of the term. Shorten the loan and the same S$900 is spread over fewer payments:

The instinct to clear an expensive debt quickly is exactly backwards on this product. A one-year renovation loan costs less in absolute interest — S$799 against S$3,869 — but the money is twice as expensive per year of use.

And you cannot escape by paying it off mid-term either. DBS charges a prepayment fee of 1% of the outstanding amount; OCBC's published terms set theirs at 2% of the amount prepaid, with a month's written notice or a month's interest in lieu. Settle a DBS loan after a year and the outstanding S$24,570 attracts a S$246 exit charge. These are small numbers, but they point the same way as the fee structure: the product is designed to be held to term.

Why you can't just put it on the mortgage

The obvious response is to borrow the renovation money at 1.40% instead of 4.88%. For most of the people asking, that door is shut, and it is shut in two separate ways.

CPF will not pay for it. The CPF Board's position is unambiguous: "CPF savings cannot be used for renovation, improvement or repair work for your property," and you "will need to use your own cash savings to cover the costs" (CPF Board). Ordinary Account money that can fund a downpayment, the loan itself, stamp duty and legal fees stops at the front door.

Cashing out equity is a private-property privilege. An equity term loan lets an owner borrow against the value of the property at home-loan rates — but only on private property. HDB flats cannot be used to draw equity this way. The asymmetry is worth stating plainly, because it runs opposite to need: the condo owner, who is least likely to be stretched, can borrow renovation money at roughly 1.4% to 1.6% secured against the unit. The BTO or resale flat buyer, facing the larger renovation relative to income, is pushed to an unsecured product capped at S$30,000 at nearly four times the rate.

A cap that hasn't moved

That cap deserves scrutiny. The rule across the banks is S$30,000 or six times monthly income, whichever is lower — so it bites twice, and the income test binds for anyone earning under S$5,000 a month:

It is worth being clear that this is a banking convention, not a regulation. MAS's industry-wide unsecured borrowing limit is twelve times monthly income (MAS), and renovation loans sit outside the unsecured credit rules entirely. There is no S$30,000 statutory cap, whatever some calculator pages claim. The banks set it, and they have not moved it while renovation costs rose. Indicative 2026 figures put a four-room BTO renovation at roughly S$40,000 to S$56,000 and a four-room resale at S$55,000 to S$83,000. On a S$48,000 BTO job the cap covers 62%; on a S$69,000 resale job, 43%. The remainder comes from cash, a personal loan, or a credit line — all of which cost more.

What actually reduces the bill

Two levers are real, and both involve the mortgage rather than the renovation loan.

The first is bundling. DBS and POSB offer 3.38% (EIR 4.49%) to their own home loan customers, valid to 30 September 2026 — that takes the five-year cost from S$4,769 to S$3,548. Maybank offers 4.08% to its home loan customers, and 2.50% for the first year to HDB home loan customers, though Maybank publishes no EIR on that page, so the fee load there is not directly comparable. Note what these have in common: every meaningfully cheaper rate is gated on already holding the mortgage with that bank. The renovation loan is a retention product. Price it when you are choosing or refinancing the mortgage, not three weeks after.

The second is sequencing. If you are refinancing anyway and own private property, the renovation is a reason to size the new facility properly rather than to take a second, dearer loan alongside it — subject to TDSR, valuation, and the CPF refund that reduces what you can draw.

Neither lever is available to someone who has already signed. Which is the practical point: the renovation loan is the one piece of a property purchase that people shop for last, after the excitement of the keys, and it is the piece where the rate is highest and the fine print does the most work.
