Do the sums before anyone sells you anything
Six calculators and a 1km school-catchment map, built for the rules that apply in 2026. Every answer comes with the full workings shown line by line. No email gate, no sign-up.
The tools
Seven tools, each settling one expensive question
Stamp duties, loan limits, grants and school catchments decide more deals than psf ever will. Each tool cites the rule it runs on, with the date I last checked it.
1km Primary School Check
Pick any of the 179 primary schools and see every condo, apartment and EC inside the 1km band, mapped and priced off real transactions.
Home Loan Rates & Repayment
Every published bank rate for HDB, private, BUC, commercial and industrial — plus the instalment, total interest and LTV on each.
ABSD Calculator
0% to 65% depending on your residency and how many homes you'll own. 2026 rates.
Stamp Duty (BSD) Calculator
The duty every buyer pays, tiered from 1% to 6% of the price. The one nobody escapes.
Mortgage Affordability
TDSR 55%, MSR 30%, 4% stress rate. What the bank will actually lend you, in dollars.
SSD Calculator
Selling within 4 years of buying? The tax runs from 4% to 16% of your sale price.
HDB Grant Calculator
EHG, FHG and proximity grants. Up to $230K in CPF grants for eligible first-timer families.
How these work
No gates. No fine print. Three steps.
1. Run the numbers. The answer and the full line-by-line breakdown appear instantly. Nothing is hidden behind a form.
2. Keep a copy if you want one. Each tool has an optional "send me this breakdown" form. One message, no drip campaign, no spam.
3. If your case isn't standard, ask before you act. Mixed-nationality couples, trust purchases, selling inside four years. These are exactly the cases calculators get wrong, and the wrong answer costs five or six figures.
Rates are cited on every tool, with the date I last checked them. If IRAS or MAS changes a rule, the tool gets updated and re-dated.

Tell me your situation in two lines. I'll point you to the right tool, or run the numbers with you. Even if the right answer is "wait a year".
