Terra Hill Mortgage Loan Calculator
The calculator below works out the downpayment and the monthly loan repayment on a unit at Terra Hill. It accounts for nationality and existing property count, which together set the loan-to-value limit and the Additional Buyer’s Stamp Duty payable. Current prices by bedroom band are on the Terra Hill price list, and the sales team can confirm the exact figure for a specific stack and floor.
Enter the following values:
1. Purchase Price
2. Existing Mortgage (Are you currently paying for any house loan?)
3. Interest Rate (Currently 3% to 4%)
4. Tenure (Loan years)
5. Nationality
6. Existing Property (Do you currently own any property?)

What the Calculator Returns
The calculator produces two tables, and between them they account for the whole cash and loan commitment rather than a single monthly figure.
Downpayment Calculation covers what is payable before construction milestones begin: the 5% booking fee, which is cash only and cannot come from CPF, then Buyer’s Stamp Duty on the tiered scale, Additional Buyer’s Stamp Duty according to the nationality and existing-property answers given, the remaining 15% of the downpayment, and the law firm charges. It totals them, so the figure returned is the sum actually required in cash, not just the 20%.
Instalment Calculation stages the remaining 80% across the construction and handover milestones. Each row shows the percentage, whether that stage is met from cash, from CPF or from the loan, and the amount. The early stages appear as lump sums because they fall due before the loan is fully drawn. Once the loan starts drawing, the figures become monthly instalments.
Read together, the two tables account for 100% of the purchase price: 20% in the downpayment table and 80% across the remaining stages.
Loan-to-Value Limits and the Cash Component
How much can be borrowed depends on the number of outstanding housing loans already held. A first housing loan is capped at 75% loan-to-value, with at least 5% of the purchase price payable in cash and the balance in cash or CPF. A second concurrent housing loan is capped at 45% loan-to-value with 25% in cash, and a third or subsequent loan at 35% with 25% in cash.
Separately, the Total Debt Servicing Ratio framework caps total monthly debt obligations, across every loan held rather than just this one, at 55% of gross monthly income. That cap usually sets the loan quantum before the property price does.
These limits are set by regulation rather than by the developer, and they apply to any private residential purchase in Singapore.
The Interest Rate to Enter
The 3% to 4% range suggested above is a stress-test planning figure, not a rate any bank has quoted. Housing loan rates in Singapore move with the market and differ between banks and packages, and banks assess affordability against a floor rate higher than the one they lend at.
The sensible approach is to run the calculation twice, once at the rate actually quoted and once at 4%, and confirm the higher result is still workable. Over a long tenure, a movement of half a percentage point changes the monthly instalment by more than most buyers expect. A banker or mortgage broker can supply current quotes.
How the Progressive Payment Scheme Spreads the Cost
Terra Hill is an uncompleted development, so it is sold under the standard Progressive Payment Scheme. The purchase price is not drawn in one go, and the monthly instalment climbs as each stage is drawn down rather than starting at the full amount on day one.
The schedule runs to ten stages. Twenty per cent falls due before any construction draw: 5% on exercising the Option to Purchase, then 15% on signing the Sale and Purchase Agreement within 8 weeks of the Option date. Forty per cent is drawn across the construction milestones, with 10% each at foundation and at the reinforced concrete framework, then 5% each at walls, ceiling, doors and windows, and car park, roads and drains. The remaining 40% falls at and after handover, with 25% at Temporary Occupation Permit and the final 15% on legal completion.
Expected Temporary Occupation Permit for Terra Hill is 9 January 2028, and expected legal completion is 9 January 2031, so the 25% and 15% instalments fall at those points.
There is no Deferred Payment Scheme on offer, as that option is not currently available for private residential launches. The full stage-by-stage table is on the Terra Hill price page.
Stamp Duty on Top of the Purchase Price
Two stamp duties may apply, and neither can be financed. Both are payable in cash on top of the purchase price and the loan.
Buyer’s Stamp Duty is payable by every buyer on a tiered rate structure, charged on the higher of the purchase price or the market value assessed by IRAS.
Additional Buyer’s Stamp Duty depends on residency status and on how many residential properties are already owned. Singapore Citizens buying a first residential property do not pay it. Rates rise for subsequent properties, and for Permanent Residents and foreign buyers. Married couples where at least one spouse is a Singapore Citizen may be able to claim ABSD remission on a second property, subject to conditions including the sale of the first within the prescribed timeframe.
Both fall due within 14 days of signing the Option to Purchase or the Sale and Purchase Agreement, whichever comes first. The full rate structure for both duties is on the Terra Hill price page.
What Else to Budget For
Beyond the purchase price, the loan and stamp duty, the recurring cost to plan for is the monthly maintenance fee. At Terra Hill this is $480 a month for the 2 Bedroom and 2 Bedroom with Study types, $480 to $560 for the 3 Bedroom types, $560 to $640 for the 4 Bedroom types, and $640 to $720 for the 5 Bedroom types. It begins at completion rather than at purchase.
Legal fees, valuation fees and fire insurance are the other standard items. Current prices by bedroom band are on the Terra Hill price page.
What the Calculator Cannot Tell You
Three figures remain specific to the buyer and sit outside the tool.
The rate a bank will actually quote. Only the lending bank can confirm it, and the rate applies for a fixed period rather than for the life of the loan.
The applicable loan-to-value limit. The standard assumption is not universal. The limit depends on the number of outstanding housing loans held and on the loan tenure set against the borrower’s age.
Whether the loan is approved at all. The Total Debt Servicing Ratio is assessed on documented income, and variable or self-employed income is discounted before the calculation is run.
For a figure worked against a specific profile, including how Buyer’s Stamp Duty and any Additional Buyer’s Stamp Duty apply, contact the sales team.
The figures produced by this calculator are indicative and for general guidance only. They do not constitute financial advice or a loan offer. Borrowing capacity should be confirmed with a licensed banker or mortgage broker before committing to a purchase.
