When you buy an uncompleted condo like One Chuan Grove, the price is paid in stages that follow construction. This calculator lays out those stages so you can see when each payment falls due and how much may come from cash, CPF or your loan.
Why this matters
Many buyers know their total budget but not the timing of each payment. That timing is important if you are waiting for an HDB sale, a bonus or other funds. Seeing the schedule laid out helps you plan cash flow and avoid surprises when payment notices arrive. It is also a good way to check that your emergency savings stay intact throughout the construction period.
How the stages work
The standard schedule starts with the option fee and the payment when you exercise the option, followed by milestones such as foundation, structure, walls, roof, services, TOP and legal completion. The stage percentages shown by the calculator follow the current published schedule; we do not restate them here because they are set by regulation.
Completion is estimated at end 2030, according to the ERA project highlights, but the TOP date has not been announced, so the calendar timing of later stages cannot be fixed yet. Treat any dates you enter as assumptions.
Using the results
Pair the schedule with the mortgage calculator to see monthly instalments at each stage, and read the payment scheme page for a plain-language explanation.
