Monthly mortgage = PMT(rate ÷ 12, tenure × 12, loan drawn to date), as in column H of the workbook. “After CPF” = monthly mortgage − CPF contribution of $1,800(column I); a negative figure means your CPF contribution more than covers the instalment. The workbook treats the loan drawn to date as the outstanding balance (it does not reduce it for principal repaid during construction).

Total interest is not shown: the workbook does not calculate it, so any figure would be an assumption outside the source spreadsheet.

- Monthly mortgage at each stage = standard amortising repayment (Excel
PMT) on the total loan drawn so far, using that stage’s interest rate and tenure. - You pay 100% − LTV of the price in order: booking fee 5% (cash), exercise fee 15% (cash/CPF), then the construction stages until your share is used up. The bank funds every stage after that (at 75% LTV: half of Foundation onwards, as in the workbook).
- Buyer Stamp Duty uses the workbook formula: 4% − $15,400 below $1.5M, 5% − $30,400 up to $3M, 6% − $60,400 above. This matches IRAS residential rates for prices of $1M and above; below $1M the workbook formula understates BSD.
- The last stage (“CSC”) combines the final 15%. Under the standard Singapore scheme this is usually 13% at legal completion plus 2% at CSC, so the full instalment often starts earlier than shown.
- Stage timing labels (e.g. “Q4 2027”) and months per stage are indicative only and don’t affect the amounts.
- The workbook does not calculate total interest or reduce the loan balance for principal repaid during construction.
- Figures are estimates for discussion only and are not a loan offer. Confirm actual amounts with your bank and lawyer.
