Disbursement schedule by milestone

Your own cash and CPF are paid first: 20% by the S&P, and any balance of your down payment at the next stages. The bank disburses only after that, and 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.

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 the foundation stage, that is only a small share of your loan. The last disbursement is made at CSC; from then on you pay the full monthly repayment shown here.

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 the SSD Period. Check with your lawyer to confirm how much SSD is applicable.

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.
