The stage timings are out of order. Each stage should be the same month as, or later than, the one before it.

A loan above 75% of the price is over the limit for a bank loan. The table uses 75%.

Instalments start small and rise with each drawdown. The biggest jump comes at the Temporary Occupation Permit, when 25% of the price falls due.

How Progressive Payments Work

When you buy a private home that is still being built, you do not pay the full price at once. The standard Sale and Purchase Agreement sets out a payment schedule tied to construction: 5% to book, another 15% within 8 weeks, then 10%, 10%, 5%, 5%, 5% and 5% as building stages are finished, 25% when the Temporary Occupation Permit is issued, and the last 15% on legal completion.

Your own cash and CPF go in first. Once your share is used up, the bank pays the developer directly at each stage, and your loan grows a step at a time. You pay instalments only on what has been drawn, so they begin low and rise as the building goes up.

This matters for cash flow. A buyer who is still paying for a current home needs to know when each jump arrives, not just the final figure. Change the timing boxes to match the developer's expected dates and print the table for the client.

Assumptions And Limits

The stages and percentages are the normal payment scheme in the standard Sale and Purchase Agreement under the Housing Developers Rules (Forms 4 and 5). The booking fee can be 5% to 10% of the price; this tool uses 5%, with the rest of the first 20% due within 8 weeks of the Option date. A deferred payment scheme, if the developer offers one, is different.
The stage dates are your own estimates. Developers give notice as each stage is finished, and construction can run faster or slower. Only the booking date and the 8-week date are fixed by the rules.
The buyer's own money is used first, then the loan. A minimum of 5% of the price is cash (the rule for a bank loan at 75% loan-to-value); the rest of the buyer's share comes from the CPF figure you enter, then cash. Lower loan limits and a higher cash share apply to buyers with other home loans.
The instalment is recalculated after each drawdown on the outstanding balance over the remaining tenure, with the tenure starting at the first drawdown and the rate staying level. Banks may calculate it differently, and some packages charge interest only during construction.
Excludes Buyer's Stamp Duty, Additional Buyer's Stamp Duty, legal fees and maintenance charges from the date of possession. The last 15% is shown on one date, although part of it is released only when the Certificate of Statutory Completion is issued.
