Disbursement schedule by milestone

Order of Payment	Progress of Payment	Percentage of Payment

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?

The standard sale agreement in the Housing Developers Rules (Form 5) sets the schedule: 5% booking, 15% on S&P signing (or 20% total with the booking), then 10% foundation, 10% reinforced concrete framework, 5% partition walls, 5% roofing, 5% door and window frames/wiring/plumbing/plastering, 5% car park/drains/roads, 25% at TOP (Temporary Occupation Permit), and the final 15%, which Form 5 sets out in parts across the Completion Date, the CSC (Certificate of Statutory Completion) and the Final Payment Date.

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 the final 15%, around 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.

Does this calculator handle the deferred payment scheme?

No. This calculator assumes the standard progressive payment schedule above. A deferred payment scheme follows a different schedule, so check the one in your own option and sale agreement.
