Detailed Guide Coming Soon
We're working on a comprehensive educational guide for the HDB Eligibility & Grant Calculator. Check back soon for step-by-step explanations, formulas, real-world examples, and expert tips.
The HDB Eligibility calculator helps prospective flat buyers in Singapore determine whether they qualify to purchase a new or resale HDB (Housing Development Board) flat and estimate the grants they may receive. HDB flats are subsidised public housing available exclusively to Singapore Citizens (and some PRs under specific schemes). To buy a new Build-To-Order (BTO) flat, at least one applicant must be a Singapore Citizen, the applicants must form a valid family nucleus, and they must not own or have recently disposed of private property. Income ceilings apply: for BTO non-mature estates the ceiling is $14,000 gross household income per month for a 4-room or larger flat, while the Plus Scheme allows up to $21,000. For resale flats, the income ceiling for grants applies separately. The cornerstone of HDB affordability is the Enhanced Housing Grant (EHG), which provides up to $120,000 for households with incomes below $9,000 per month — the grant tapers off for higher incomes. First-timer couples also benefit from the Additional CPF Housing Grant (AHG) for resale flats and the Proximity Housing Grant (PHG) for buying near parents. Singaporean first-timers also get priority balloting for BTO flats. The calculator helps you input your household income, citizenship status, family composition, and flat type to determine eligibility and grant amounts, so you can plan your finances accurately before applying.
EHG Amount = f(Gross Monthly Household Income) up to $120,000; Monthly Instalment = (Flat Price - CPF OA - Grant) × [r(1+r)^n / ((1+r)^n - 1)]; Affordability = Monthly Instalment ≤ 25% Gross Income
- 1Confirm citizenship status — at least one applicant must be a Singapore Citizen for most BTO schemes.
- 2Establish a valid family nucleus: married/engaged couple, family (with parents/siblings/children), or single citizen aged 35+.
- 3Calculate gross monthly household income by summing all applicants' and occupiers' assessed income.
- 4Check income against the applicable ceiling: $14,000 for BTO standard, $21,000 for Plus Scheme, or nil ceiling for resale without grant.
- 5Determine Enhanced Housing Grant eligibility based on income (maximum $120,000 for lowest income tier).
- 6Check whether Additional CPF Housing Grant (AHG) or Proximity Housing Grant (PHG) applies for resale purchases.
- 7Verify that no applicant owns or has recently disposed of private property within 30 months.
Income below $9,000 qualifies for maximum EHG tier
Combined income of $5,000 falls in the EHG income band qualifying for $80,000 grant. As first-timers they also receive additional ballot chances.
PHG $30,000 if living with parents, $20,000 if within 4km
The SC-PR couple qualifies under the SC/SPR family scheme. Proximity grant is awarded for buying close to parents.
Singles receive 50% of couple EHG
Singles aged 35 and above can apply for 2-room Flexi BTO flats in any estate. EHG for singles is half the couple amount at the same income level.
Plus Scheme has higher income ceiling but fewer grants
Income above $14,000 disqualifies from standard BTO but falls within the $21,000 ceiling for Plus Scheme flats. No EHG applies as income exceeds $9,000.
Professionals in real-estate use Hdb Eligibility Calc as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Hdb Eligibility Calc into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Hdb Eligibility Calc to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Hdb Eligibility Calc for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.
Extreme input values
In practice, this edge case requires careful consideration because standard assumptions may not hold. When encountering this scenario in hdb eligibility calculator calculations, practitioners should verify boundary conditions, check for division-by-zero risks, and consider whether the model's assumptions remain valid under these extreme conditions.

| Grant | Max Amount | Eligibility |
|---|---|---|
| Enhanced Housing Grant (EHG) | $120,000 | Income ≤$9,000; first-timer family |
| Proximity Housing Grant (PHG) – with parents | $30,000 | Resale; buy to live with parents/child |
| Proximity Housing Grant (PHG) – near parents | $20,000 | Resale; buy within 4km of parents |
| Singles Grant | $25,000 (resale) | Single SC ≥35 buying resale 2/3/4-room |
| EHG Singles | $60,000 | Single SC; income ≤$4,500; BTO or resale |
What is the income ceiling for a 4-room BTO flat?
Hdb Eligibility Calc is a specialized calculation tool designed to help users compute and analyze key metrics in the real-estate domain. It takes specific numeric inputs — typically drawn from real-world data such as measurements, rates, or quantities — and applies a validated mathematical formula to produce actionable results. The tool is valuable because it eliminates manual calculation errors, provides instant feedback when exploring different scenarios, and serves as both a decision-support instrument for professionals and a learning aid for students studying the underlying principles.
What is the Enhanced Housing Grant (EHG)?
In the context of Hdb Eligibility Calc, this depends on the specific inputs, assumptions, and goals of the user. The underlying formula provides a deterministic relationship between inputs and output, but real-world application requires interpreting the result within the broader context of real-estate practice. Professionals typically cross-reference calculator output with industry benchmarks, historical data, and regulatory requirements. For the most reliable results, ensure inputs are sourced from verified data, understand which assumptions the formula makes, and consider running multiple scenarios to bracket the range of likely outcomes.

Pro Tip
If your household income is just above a grant threshold, check whether any non-applicant occupiers can be removed from the application. Only applicant incomes count for most grant calculations, but all occupier incomes affect the BTO income ceiling.
Did you know?
More than 80% of Singapore residents live in HDB flats — one of the highest public housing occupancy rates in the world. The HDB was established in 1960 and has built over 1 million flats, transforming Singapore from a country with severe housing shortages to a home-owning society in less than two generations.
