What is a BTO Progressive Payment Scheme?
The progressive payment scheme spreads the cost of your BTO flat across construction milestones over 3 to 5 years instead of requiring full payment upfront. Payments are triggered as HDB certifies that each construction stage is completed, from foundation work through to key collection.

How BTO Progressive Payments Work
When you purchase an HDB BTO flat, you don't pay the full amount upfront. Instead, payments are spread across construction milestonesover 3–5 years. This is known as the progressive payment scheme.
The journey begins with a booking fee ($500 for 2-room Flexi, $1,000 for 3-room, $2,000 for 4-room and above) paid in cash at flat selection. When you sign the Agreement for Lease, you pay a 5% downpayment (minus the booking fee). Subsequent payments are triggered as construction reaches specific milestones.
You can use your CPF Ordinary Account for most payments after the booking fee. Planning your CPF and cash usage early helps ensure you have sufficient funds at each stage. The largest single payment is typically at building completion (25%), so ensure your CPF OA has adequate funds by that point.

Frequently Asked Questions

Can I use CPF for BTO progressive payments?expand_more
Yes, you can use your CPF Ordinary Account (OA) savings for most BTO progressive payments, including the downpayment (after the initial booking fee which must be in cash). CPF can be used to pay for the purchase price, stamp duty, and legal fees. The amount you can withdraw is subject to CPF's Valuation Limit and withdrawal limits based on your OA balance.
When is each progressive payment due?expand_more
Each progressive payment is triggered when HDB certifies that a construction milestone has been reached. You will receive a notice from HDB to make payment within 14 days of the milestone certification. The entire process from booking to key collection typically takes 3-5 years for BTO flats, depending on the project timeline.
What happens if I cannot make a progressive payment on time?expand_more
If you fail to make a progressive payment within 14 days of HDB's notice, HDB may charge interest on the overdue amount. Persistent non-payment could result in forfeiture of the flat and the payments already made. If you face genuine financial difficulties, you should contact HDB early to discuss possible arrangements such as using more CPF savings or restructuring the payment schedule.
