You make ten payments over four to five years, using cash, CPF and your bank loan. The first 5% of the purchase price must be cash. By week 8, you will have paid 20% of the purchase price — a 5% booking fee, then 15% more when you sign the Sale and Purchase Agreement (S&P). This tool shows every payment stage, from the booking fee to legal completion: what must be cash, what CPF can cover, when your bank loan starts, and how your monthly instalment grows once your loan starts, stage by stage.

How to read this schedule?
You fund the initial stages yourself. After that, the bank takes over. If this is your first home loan, the 5% booking fee must be cash, and the 15% signing payment can be cash or CPF. On a second or later loan, at least 25% must be cash. Stamp duty is due 14 days after you exercise the option. If ABSD applies to your purchase, stamp duty alone can be larger than any single payment in the schedule.
Every stage after the foundation is bank-funded, so your instalment increases with each stage. Because interest is only charged on what's been released, you only start to pay the full instalment at legal completion — about a year after you get the keys.

What do buyers miss?
Buyers usually miss two things.
The quiet years. From the day you sign to the day you get your keys, you're paying a growing instalment on a home you can't live in yet — often on top of rent or another mortgage. Plan for that extra cost, on top of the total price.
The cost of selling early. Nothing stops you from selling early — but Seller's Stamp Duty is charged on the full selling price, up to 16%, if you sell within four years of purchase under the July 2025 rules. That stamp duty bill is usually large enough to wipe out any profit from selling early, so most buyers hold on until the four-year period ends instead.

Frequently asked questions
What are the standard payment stages?
There are ten stages, set by the Housing Developers Rules. First, a 5% booking fee in cash. Then 15% when you sign the sale agreement, within 8 weeks. Next, 10% when the foundation is done, and 10% when the concrete framework is done. After that, 5% each for the partition walls, roofing, doors and wiring, and roads and car parks. Finally, 25% when the keys are ready, and 15% at legal completion.
How much of it must be cash?
If this is your first home loan at 75%, the 5% booking fee is the only cash payment needed — the remaining 20% can come from your CPF Ordinary Account. A second or later loan needs at least 25% in cash. You can also pay stamp duty from CPF, though most buyers pay cash first and claim it back later.
When does the bank start paying?
Only after your own cash and CPF run out. At a 75% loan, your 25% covers the booking fee, the signing payment, and part of the foundation stage. Once that runs out, your bank pays out more of your loan whenever a stage of construction is completed — and each payout raises your monthly instalment.
Why is the full instalment only reached at legal completion?
Because 15% of the price is only paid at legal completion — which usually happens about a year after you get your keys. Until then, only part of your loan has been paid out, so your monthly instalment is smaller than the full instalment you'll reach at legal completion.
Can I sell before the keys are ready?
Yes — selling before you collect your keys is called a sub-sale. If you bought on or after 4 July 2025, Seller's Stamp Duty applies for four years at rates up to 16%, leaving you with little or no profit from the sale. Use our stamp duty calculator to check the numbers first.
Disclaimer
This calculator is an educational example of the standard Progressive Payment Scheme, not financial advice. Your actual payment amounts and timing depend on your Sale & Purchase Agreement, and on when the developer's architect certifies each construction stage — real schedules often run earlier or later than the typical one shown here. How your loan is paid out, how interest builds up, and how much CPF you can use all vary by bank and by your own situation. Verify your exact schedule against your S&P Agreement and confirm financing details with your bank or lawyer before relying on any figure. PropertyInsider.sg disclaims liability for decisions made on the basis of this tool.
Talk it through with an advisor
A calculator gives you the number; it can't tell you what to do with it. If you want to work through what these figures mean for your own situation — budget, ABSD position, timing an HDB sale, or comparing launches against resale options — you can request a one-to-one consultation.
No obligation. The first conversation is about your goals.
