Deferred Payment Scheme (DPS) Calculator Singapore 2026
DPS vs Normal Progressive Payment — Cash Flow, Construction Interest & Lifetime Cost
Compare the Deferred Payment Scheme (DPS) against the Normal Progressive Payment Scheme (NPS) for new launch private property in Singapore. Under DPS, you pay a larger upfront amount (typically 20%) and defer the rest until TOP — saving you construction-period interest but usually at a developer premium of 2%–5% on the purchase price. Under NPS (Building Under Construction / progressive payment), you pay in stages tied to milestones and your bank pays construction loans progressively. This calculator quantifies the total cost of each scheme including the DPS premium, construction interest, lifetime mortgage interest, and cash flow during the construction wait.
Paid now; rest deferred to TOP
Added to price for DPS privilege
Under DPS, the developer charges a premium on the purchase price for deferring payment. The total DPS price = base price + premium. This premium is the cost of the deferment benefit.
Under DPS, the cash you did NOT need to pay during construction can be invested. Enter your expected annual return on these deferred funds (e.g., 3% for T-Bills, 5% for REITs). Set to 0 if you would not invest.
Enter the property price, DPS upfront percentage, developer premium, mortgage rate, and tenure to compare the total cost and cash flow of DPS vs the Normal Progressive Payment Scheme.
Deferred Payment Scheme (DPS) Singapore 2026 — How It Works, When It Was Used & What Developers Offer Today
The Deferred Payment Scheme (DPS) was a popular payment option for new launch private properties where buyers paid a small initial sum and deferred the bulk to completion. Under the standard DPS: pay 5%–20% at booking, pay the rest only at TOP (3–5 years later). This eliminated construction-period mortgage interest — a significant benefit when SORA was high. The government suspended the mainstream DPS and Interest Absorption Scheme (IAS) in 2007 for residential properties to curb speculation. However, some developers still offer DPS-like arrangements for specific new launches (particularly for luxury developments, commercial properties, or overseas projects). The core question: is the developer’s DPS premium worth the construction interest you avoid?
DPS vs Normal Progressive Payment (NPS) — Key Differences
| Feature | DPS (Deferred Payment) | NPS (Normal Progressive) |
|---|---|---|
| Upfront payment | Typically 20% at booking | 5% option + 15% at S&P only |
| During construction | No further payments | Progressive milestone payments |
| Mortgage timing | Full loan taken at TOP | Loan drawn progressively |
| Construction interest | None (deferred) | Paid by buyer (2%–5% of price) |
| Purchase price | Higher (2%–5% premium) | Base price |
| Cash flexibility | Keep cash invested during build | Cash committed progressively |
| Availability | Specific launches only | Standard for all new launches |
How This DPS Calculator Works — Premium vs Interest Saved & Lifetime Cost
Step 1 — Enter Property and DPS Terms
Enter the base property price (NPS price) and the DPS upfront percentage (what you pay now). Enter the developer’s DPS premium (added to the price for the deferment privilege) and the construction wait period. The DPS total price = base price × (1 + premium%).
Step 2 — Enter Mortgage and Investment Details
Enter the mortgage rate and tenure. Under NPS, you pay construction-period interest on the progressively drawn loan. Under DPS, you pay the premium upfront but avoid construction interest. Enter the investment return you could earn on the deferred cash during construction.
Step 3 — See Total Cost and Cash Flow Comparison
The results compare: total lifetime cost (DPS vs NPS), cash required during construction, construction interest savings, investment return on deferred funds, and the NPS milestone payment schedule with exact amounts and timing. The stacked bar chart shows where each scheme’s total cost comes from.
3 Real Singapore DPS Examples — DPS Wins, NPS Wins & Borderline
S$1.5M, 3% Premium, High Rate — DPS Wins
S$2M, 5% Premium, Low Rate — NPS Wins
S$1.8M, 4% Premium, Invest Cash
3 Expert DPS Tips — When DPS Makes Sense, Using the Cash Gap & The Premium Negotiation
DPS Makes Sense When the Premium Is Less Than the Construction Interest
The simple rule: choose DPS only if the developer premium < NPS construction interest. Construction interest under NPS is approximately: (loan amount × 50% average drawdown × mortgage rate × years). On S$1.2M loan at 4% for 3 years: interest ≈ S$72,000. If the DPS premium is S$45,000 (3% on S$1.5M), DPS saves S$27,000. If the premium is S$60,000+ (4%+), NPS is cheaper. The break-even premium % = (avg loan × 50% × rate × years) / price × 100. Use this calculator to find the exact break-even for your property. Also factor in: investment return on the deferred cash — keeping S$1.2M invested at 4% for 3 years adds S$150,000 in returns (partially offsetting the DPS premium even if it seems expensive).
Invest the Deferred Cash in T-Bills or MMFs During Construction
The real DPS advantage is not just avoiding construction interest — it is keeping the deferred cash working for you. Under DPS, you pay only 20% upfront. The remaining 80% you would have paid progressively under NPS stays in your bank account. Invest it in Singapore T-Bills (current yield ~3.5%), fixed deposits (3%–4%), or money market funds (~3%). On S$1.2M deferred for 3 years at 4%: investment return = ~S$150,000. This nearly always makes DPS more attractive when you factor in investment returns. The DPS premium rarely exceeds what you can earn by investing the deferred amount, especially in a higher-rate environment.
Negotiate the DPS Premium — Developers Offer It to Attract Buyers
DPS is not a fixed product — it is offered at the developer’s discretion, typically when they want to attract early buyers or clear inventory. If a developer is offering DPS at 5%, ask if they will match 3% (especially for multiple units, larger units, or early ballot selections). Developers sometimes bundle DPS with other incentives (stamp duty rebate, furniture vouchers, early bird discounts). If the developer has been holding units for 12+ months (check URA new sale statistics), they are more motivated to offer DPS at a lower premium. In a competitive market, developers may offer DPS at 0% premium (absorbing the interest cost themselves as a sales incentive — effectively the IAS model).
