A month-by-month simulation of a new launch investment: your capital outlay including stamp duty, interest across the progressive loan drawdown, rental after vacancy and costs, and exit costs — including the SSD schedule that now reaches 16% on early sales. The output is the number that matters: annualised return on the cash you actually put in.
The first is gross thinking: "bought at S$1.8M, sold at S$2.3M, made half a million" ignores roughly S$70,000 of stamp duty on the way in, years of loan interest in the middle, and 2% commission plus legal fees on the way out. The second is time-blindness: a 25% total gain sounds identical whether it took four years or fourteen, but one compounds at 5.7% a year and the other at 1.6% — below the CPF Ordinary Account's 2.5%. The third, since July 2025, is the exit tax: sell within four years of purchase and SSD takes 4–16% of the full sale price, which for a new launch means almost any sale before or around TOP is taxed. This calculator confronts all three, simulating the cash flows month by month on the same progressive payment engine as our payment schedule calculator.
The appreciation field defaults near what actually happened: across 32,414 matched profitable resale exits from 2018 to 2026, the median seller earned about 3.6% a year before transaction costs — and that dataset excludes losses entirely, so even it flatters the market. Our exit dashboard lets you look up the base rate for your district, holding period and entry type before you type a hopeful number here. If the deal only works at 6% a year, the data says you are betting on an outcome most profitable sellers did not achieve.
Total gain = net sale proceeds (sale price − commission − sale legal − SSD) − purchase price − stamp duties − renovation − purchase legal − total loan interest + net rental collected. ROI divides that gain by your capital outlay (downpayment + duties + renovation + legal), and the annualised figure compounds it over the total holding period from booking to sale.
Because a new launch loan is drawn progressively, interest in the early years accrues only on the disbursed portion. A flat-interest shortcut overstates cost before TOP and understates it after; the simulation draws down the loan at each construction stage and recalculates the instalment, exactly as the payment schedule calculator does.
Yes, automatically. It measures your total holding period from booking to sale and applies the schedule for purchases on or after 4 July 2025 — 16/12/8/4% within years one to four, zero after. A red SSD line appears in the breakdown whenever your chosen exit triggers it.
The median profitable exit in our 2018–2026 matched-pair dataset annualised about 3.6% before costs, with suburban districts higher and prime districts lower. Since the dataset excludes losses, treat 3–4% as an optimistic-but-grounded base case and always test 2% and 0% alongside it.
No. Rental income is taxable at your marginal rate (or a flat 24% for non-residents), and the calculator shows pre-tax rental figures. Property tax at non-owner-occupier rates is included via the annual property tax input.
A calculator gives you the number; it can't tell you what to do with it. If you want to work through what these figures mean for your own situation — budget, ABSD position, timing an HDB sale, or comparing launches against resale options — you can request a one-to-one consultation.
