Summary

Final monthly repayment (at TOP)

Total cash + CPF outlay: $0
Total loan disbursed: $0

Disbursement schedule by milestone

Cash/CPF is drawn first (20% down payment). Loan disbursements begin after Stage 3 (foundation). The bank charges interest only on the cumulative amount disbursed, so monthly servicing ramps up as construction progresses.

Results are indicative only and not a bank-approved quotation, IRAS assessment, or HDB confirmation.
Interest rates, stamp-duty rates, LTV limits and CPF rules change. Verify the latest with MAS, IRAS, HDB and your lender before transacting.
Consult a qualified mortgage broker, conveyancing lawyer, or accountant for advice specific to your situation.
SellMyHouse.sg accepts no liability for decisions made on the basis of these calculations.

FAQ

Frequently Asked Questions

What is the standard progressive payment schedule?

URA's Housing Developers Rules set a fixed schedule: 5% booking, 15% on S&P signing (or 20% total with the booking), then 10% foundation, 10% reinforced concrete, 5% brick walls, 5% roofing, 5% doors/wiring/plastering, 5% car park/drains/roads, 25% at TOP (Temporary Occupation Permit), and final 15% on CSC (Certificate of Statutory Completion).

Why does interest start small and grow?

The bank only charges interest on the cumulative amount it has disbursed to the developer. At foundation stage, that may be just 10% of your loan. By TOP, the full loan is drawn down and you're paying the 'full' monthly repayment shown here.

When does CPF kick in?

CPF Ordinary Account can be used from the S&P signing stage (15% milestone) for the down payment beyond the mandatory 5% cash. Withdrawal limits apply for older buyers or properties with shorter remaining lease — see our CPF Usage calculator.

What happens if I sell before TOP?

Sub-sale of an uncompleted unit is allowed but you'll pay Seller's Stamp Duty (SSD) if within 3 years of purchase: 12% / 8% / 4% in years 1, 2, 3 respectively. Capital gains and unrealised CPF accrued interest can also bite.

How long is the construction timeline?

Typically 3–4 years from launch to TOP for a private condo. Foundation usually completes 6–12 months after S&P; structural work spans years 2–3; TOP and CSC occur in years 3–4.

Does this calculator handle the deferred payment scheme?

No. This calculator assumes the standard Normal Progressive Payment (PPS) scheme. Deferred Payment Scheme (DPS) — where you pay only ~20% upfront and the balance at TOP — is allowed only for completed/TOP'd condos under select developer promotions and follows different mechanics.
