Progressive Payment Calculator - Singapore Private New Launch
Estimate the statutory progressive-payment schedule for an uncompleted private residential property bought from a licensed Singapore developer, including buyer funds, bank drawdowns, BSD, and loan repayments.
Features:
- Statutory Stage Breakdown: See the current private-housing percentages and construction milestones
- Bank Repayment Schemes: Compare progressive instalments with interest-only servicing until TOP
- Timeline Visualization: Interactive chart showing payment progression over time
- Loan-Capped Drawdowns: Keep every stage within the loan amount implied by your down payment
- Current Residential BSD: Includes the 6% marginal tier above S$3 million
Assumes no outstanding housing loan and a 75% maximum LTV; at least 5% is cash.
This scope assumes the loan also ends by the borrower’s age 65.
Construction-stage months are estimates; the developer’s certified notices control.
The final 15% has conditional 2% / 8% / 5% legal, CSC and final-payment timing.
Use your letter of offer. Interest-only servicing is not universal and may need cash.

Estimated Loan Repayment Timeline
The teal line is the estimated monthly loan payment after each draw; the orange line is cumulative loan servicing only. Purchase-price instalments, BSD and legal costs are excluded. Your bank’s disbursement dates, rate changes and letter of offer control.
Progressive Payment Schedule
Percentages follow the statutory private-housing schedule. Months are planning estimates because certified construction notices trigger payment. The final 15% is grouped because its 2% / 8% / 5% timing depends on legal completion, CSC and the final payment date.

Initial Payment Breakdown
The 5% booking fee is cash in this model. CPF OA may be used for the remaining purchase contribution and BSD after legal documentation, subject to CPF limits and approval.
Scope, Assumptions & Sources
This calculator covers an uncompleted private residential property bought from a licensed Singapore developer using the statutory progressive-payment schedule and a bank loan. It does not model BTO flats, EC-specific rules, resale or completed properties.
- No outstanding housing loan; loan tenure is at most 30 years and does not extend beyond age 65.
- The selected LTV is a planning ceiling, not an approval. TDSR, income, credit assessment and bank policy may reduce the available loan.
- Purchase price equals bank valuation and market value. A lower valuation can increase the cash contribution; BSD uses the higher of price or market value.
- Buyer funds are used before bank drawdown. The first 5% is cash; later buyer funds are CPF OA and/or cash, subject to CPF approval and limits.
- The entered interest rate stays constant. Actual floating rates, fees, daily-interest conventions and disbursement dates will change the result.
- Interest-only servicing and progressive principal-and-interest are different bank schemes. The letter of offer controls; some interest-only payments cannot be made with CPF.
- The final statutory 15% is displayed as one planning stage, but is normally dealt with in 2%, 8% and 5% portions under conditional completion, CSC and final-payment rules.
- Only residential BSD is estimated. ABSD, SSD, legal fees, mortgage duty, valuation fees and other transaction costs are excluded.
Verified against official guidance on 12 July 2026:
Planning estimate, not financial or legal advice. Check the developer’s Sale & Purchase Agreement, certified notices, your bank’s letter of offer, CPF approval and conveyancing lawyer’s completion statement before relying on any amount.
Worked example
How a S$1 million progressive payment schedule works
This example uses the calculator defaults: a S$1,000,000 uncompleted private residential property, 25% buyer funds, a 75% bank loan, 2% annual interest, a 30-year tenure, TOP at month 30, the final modelled draw at month 42, and progressive principal-and-interest repayments.
Property price
S$1,000,000
Buyer funds
S$250,000 · 25%
Bank loan
S$750,000 · 75%
Rate and tenure
2% · 30 years
What is paid at each part of the schedule?
The statutory instalments add up to 100% of the purchase price. The calculator groups the ten payment stages into four readable parts here; its full schedule above remains authoritative for each individual stage.
| Payment group | Purchase-price instalment | Buyer funds used | Bank loan drawn |
|---|---|---|---|
| Booking and signing · 20% | S$200,000 | S$200,000 | S$0 |
| Construction milestones · 40% | S$400,000 | S$50,000 | S$350,000 |
| TOP / qualifying CSC milestone · 25% | S$250,000 | S$0 | S$250,000 |
| Completion, CSC and final payment · 15% | S$150,000 | S$0 | S$150,000 |
| Total · 100% | S$1,000,000 | S$250,000 | S$750,000 |
How is interest before the final modelled draw estimated?
The loan is not released in one S$750,000 lump sum. Each bank draw increases the outstanding balance. Between the illustrative milestone months, the calculator applies the entered rate to that balance and, for progressive principal-and-interest, recalculates the monthly instalment over the remaining tenure.
With these defaults, the model estimates S$19,042 of interest before the final modelled draw and a S$2,896 monthly payment after that draw. Under interest-only servicing, principal does not reduce before TOP; the bank's letter of offer determines the actual scheme and dates.
Progressive payment, loan repayment and amortization are different
- Progressive payment
- A purchase-price instalment owed to the developer when the contract or a certified construction milestone triggers it.
- Loan repayment
- The monthly amount paid to the bank after loan funds have been released. It services the loan; it is not another percentage of the purchase price.
- Amortization after TOP
- Principal-and-interest repayments continue after TOP and the final draw. The balance declines over the remaining loan tenure, subject to the bank's actual rate and terms.
Planning example only. Milestone months are illustrative, the final 15% is a grouped model, and actual notices, valuation, financing terms, CPF approval, taxes and transaction costs can change the amounts. See the scope and primary sources in the calculator above; verified 12 July 2026.
