A Reddit poster and his girlfriend applied for an HFE letter expecting an Enhanced CPF Housing Grant (EHG) of about S$90,000, based on her pay of S$3,000 to S$3,300 a month. The letter came back with S$65,000.
His reasoning was that he is a full-time student, so "our EHG should just be hers." But he had been interning at S$1,200 a month since the summer, and earlier in the year he worked a few months as contract staff at S$2,500 a month. HDB counted all of it.
EHG is based on your average gross monthly household income, and the way HDB calculates that average surprises a lot of buyers.
That third point is the one that does the damage. A few months of part-time or short-term work does not get "diluted" across the year. It counts as a full monthly income in your household average.
A few more things worth knowing:
EHG also has a separate pass or fail test. At least one applicant must have worked continuously for 12 months, up to two months before the HFE application, and must still be working when they apply.
If you are a full-time student, NSF, or graduated or finished NS in the past 12 months, look into Deferred Income Assessment. Eligible couples can book a flat first and have their income assessed about three months before key collection. To qualify, you must be married or applying under the Fiancé/Fiancée Scheme, both be at least 21, and at least one of you must be 30 or under.
The figures below are an illustration, not the poster's actual file. Assume she earned the midpoint of S$3,150 in each of the 12 months, and he worked three months as contract staff at S$2,500 and four months as an intern at S$1,200, with five months of no income.
Her average: S$3,150
His average: (3 × S$2,500) + (4 × S$1,200) = S$12,300 over seven months worked = S$1,757
Household average: S$3,150 + S$1,757 = S$4,907
Her income alone would have placed them in the S$3,001 to S$3,500 band (S$90,000, exactly what they expected). With his average added, they land in the S$4,501 to S$5,000 band (S$65,000, exactly what the letter said).
If his S$12,300 had been spread over 12 months instead (about S$1,025 a month), the household average would have been S$4,175 and the grant S$70,000. Averaging over months worked cost them an extra S$5,000.
EHG was raised in August 2024 to a maximum of S$120,000 for first-timer families and S$60,000 for first-timer singles. The income ceiling is S$9,000 for families and S$4,500 for singles.
| Average gross monthly household income (S$) | EHG for first-timer families (S$) |
|---|---|
| 1,500 and below | 120,000 |
| 1,501 to 2,000 | 110,000 |
| 2,001 to 2,500 | 105,000 |
| 2,501 to 3,000 | 95,000 |
| 3,001 to 3,500 | 90,000 |
| 3,501 to 4,000 | 80,000 |
| 4,001 to 4,500 | 70,000 |
| 4,501 to 5,000 | 65,000 |
| 5,001 to 5,500 | 55,000 |
| 5,501 to 6,000 | 50,000 |
| 6,001 to 6,500 | 40,000 |
| 6,501 to 7,000 | 30,000 |
| 7,001 to 7,500 | 25,000 |
| 7,501 to 8,000 | 20,000 |
| 8,001 to 8,500 | 10,000 |
| 8,501 to 9,000 | 5,000 |
Singles use a separate table in S$250 income bands, from S$60,000 (S$750 and below) down to S$2,500 (S$4,251 to S$4,500).
The takeaway: crossing a single S$500 line can cost a family S$5,000 to S$10,000 in grant. A short stint of part-time pay can easily push you across one, or more.
Always check your band against hdb.gov.sg before you budget, since the schedule has changed before.
A S$25,000 drop in EHG is S$25,000 more you need to find, from cash, CPF OA or a bigger loan.
On a 25-year HDB loan at the 2.6% concessionary rate, an extra S$25,000 of borrowing costs about S$113 a month. Put another way, every S$5,000 of grant you do not get adds roughly S$23 a month.
That assumes you have room to borrow it. HDB loans are capped at 75% of the flat's price or value. If you are already at that limit, the shortfall cannot be financed at all and has to come from CPF OA or cash.
That is why your income average belongs in your spreadsheet before your HFE application, not after.
Because the window moves with your application date, applying earlier or later changes which months are counted. That can shift your average into a different band, up or down.
Work out your number for a couple of possible application months first, make sure at least one of you still meets the employment condition, and apply when you know what the result will be.
If your HFE letter shows a number you do not expect, ask HDB for three things: the assessed average income for each person, the exact months used, and which income sources were counted.

Before adding your name to a parent's HDB flat, calculate the ABSD and LTV impact on your own future property purchase, since becoming an owner (even unintentionally via joint tenancy or inheritance) can add S$300,000 in stamp duty and, if a loan is attached, push LTV limits down enough to raise required upfront cash by up to S$750,000. All five main options for handling a parent's flat (leaving it vacant, renting it out, right-sizing, Lease Buyback, or selling) remain neutral for an adult child's own property plans only if that child stays off the title, so securing an LPA early and verifying CPF refund amounts and title arrangements are essential first steps.

Moving to a 1km address for Primary 1 priority typically adds about S$42,700 in mortgage premium over six school years (roughly S$7,100 a year), on top of about S$39,380 in one-off transaction costs for the move itself, plus potential ABSD and bridging loan costs if buying before selling. A 1km address only improves ballot odds within a registration phase and does not guarantee a place, while requiring 30 months of occupancy against a 25-year loan commitment.
