One-Third Check Calculator — HomeAnalytics

HomeAnalytics · For HDB upgraders

The Affordability Check

Three numbers are all you really need to start: your income, what you have for the downpayment, and the price you’re eyeing. We check it first against the bank’s rules — TDSR, or MSR for an EC or HDB flat, stressed at 4% — and then, separately, against our own advice. Everything else on this page is optional detail, tucked away until you want it.

TDSR 55% the bank’s ceiling, checked first
MSR 30% (HDB / EC within MOP) same 30% rule for HDB flats & ECs within MOP
4% stress test
Our advice: ⅓ a comfort line, not a rule
Your numbers stay on this page. Nothing is saved or sent anywhere unless you ask for your summary by email below — there is no account needed, and we never ask for your name, phone or address. Leave anything blank — only your monthly income is needed to run the main check.

Start here — which one are you?

Choose one. You can change it anytime.

1 Your income & what you have

This is the whole check, really. Everything in Step 2 below only sharpens the answer.

Combined monthly household income

Single borrower: your income. Joint: add both borrowers together — the bank tests your combined income.

Borrower 1

$
Salary that does not vary month to month — banks count 100% of this.
$
Bonus, commission and allowances, averaged over the preceding 12 months. Banks count only 70% of this — a 30% haircut (MAS Notice 645).
yrs
Banks cap the loan tenure on age. For a joint application we use your income-weighted average age, not the older borrower's age.
Add a second borrower (joint application)

Turn on and we add Borrower 2's income, and weight the tenure age by income.

$
Rent from a property you already own, under a stamped tenancy. Banks count only 70% of this too.
$
Car loan + personal loan + student loan + credit card minimum payments, added together as one total. Leave at $0 if you have none.
A condo is checked against TDSR: all your monthly debts, mortgage included, must stay within 55% of income.
$
Savings, bonuses, family help — cash on top of whatever your current home leaves you. First-time buyers: put all your cash here.
Slide left to keep some extra cash back as a safety buffer instead of putting it all into the purchase.
$
First-time buyers: put all the CPF OA you plan to use here. Upgraders: only CPF beyond the refund from your sale.
$
A goal, not money you have yet — we show how far you are from it, and your numbers once you get there.
$
Leave blank and we’ll show the maximum price that passes instead.
More detail — loan tenure
yrs
30 years is used for the worked example. Your actual maximum also depends on age and property type. Capping the tenure this way keeps LTV at 75% — LTV falls to 55% if tenure exceeds 30 years or runs past age 65 (MAS).
Why these numbers? — how the check works

Other debts: TDSR counts all of your monthly debt obligations, so other debts reduce what a bank can lend for housing dollar-for-dollar. MSR counts the housing instalment only.

Kept-back cash: cash you slide back as a safety buffer is not counted in your downpayment funds — it shows up in your buffer after buying.

Savings target: set the total extra cash + CPF (beyond any sale) you plan to hit before buying, and we’ll show how far you are from it — and what your numbers look like once you get there.

Your sale proceeds: don’t call the result “profit” — it is funds for your next home, split between CPF back to your OA and cash in hand.

2 Selling your current home? Optional

If you fill this in, what your sale leaves you becomes part of your downpayment above. Every field is optional — skip it and the check still runs on the cash + CPF you entered in Step 1.

Include my current home

Turn off if you’d rather rely on Step 1 alone.

$
$
Use the figure on your latest bank / HDB loan statement — not the loan you originally took.
$
yrs
We estimate the accrued interest you must refund at 2.5% p.a.
Selling costs, resale levy & exact CPF figure
$
Pre-filled at 2% of the selling price. Edit it to what you’ve actually agreed — and add GST if your agreement is “+ GST”.
$
A resale levy is generally payable when you buy a second subsidised flat or a new EC after selling a subsidised flat. It does not apply to a private condo purchase.

Instalment vs income
our advice ⅓
How to read this bar

The bar is scaled to the TDSR ceiling of 55%. The first marker is our one-third advice line; the second is the bank’s limit. Between the two is allowed — but tighter than we’d advise.

Then — our advice: the one-third check

$—

—

Best case — how close are you?

The 3/3/12 target we work towards with clients: 30% down, instalment at or under one-third of income, price at or under 12× annual household income. It is a target to aim at, not a pass or fail — the bank’s TDSR result above is the one that decides what’s permissible.

Price within 12× annual income—
30% downpayment ready—
Instalment within one-third (on a 70% loan)—

—

Why this number? — where the 12× comes from

12× is the Singapore median, not an imported rule of thumb: median household income was $12,446 a month in 2025 (SingStat) and the median condo resale was $1,710,000 in September 2026 (URA caveats via PLB Research) — a ratio of 11.4× (11.45× to two decimals), rounded to a 12× target to work towards.

Two different pots — don’t mix them up. CPF that goes back to your OA can fund the next purchase, but it is not cash in hand for the buffer, stamp-duty timing and moving costs. Mixing them up is how upgraders over-borrow.

Formulas: Bank max instalment = TDSR 55% of assessable income − other debts (for an HDB flat or an EC within MOP, the mortgage is further capped at MSR 30% (HDB / EC within MOP)) · Our advice instalment = assessable income ÷ 3 − other debts · Max loan = present value of the instalment at 4% p.a. over the tenure · Max price respects both the 75% LTV limit and your funds after 25% downpayment, Buyer’s Stamp Duty and legal fees · CPF accrued interest ≈ CPF used × [(1.025)years − 1].

Important — please read:

This calculator is indicative only, based on the numbers you entered and a 4% test rate. It is not a loan approval, not a valuation, and not financial or legal advice. Banks test your actual income, debts, age and the property, and their decision may differ. Before you commit to a purchase, check with your bank or mortgage banker, and check with your lawyer / conveyancer on the legal and CPF matters. Rules and rates can change — check MAS, HDB, CPF and IRAS for the current rules.

Sources & limits

Every number above traces back to MAS, CPF Board, IRAS, HDB and SingStat — open the list to check them.

Show sources, assumptions & limits
  • Stress test & loan caps: MAS uses a 4% medium-term rate for property loan stress-testing; TDSR is 55% and MSR 30% (HDB / EC within MOP) is 30% of gross monthly income. MAS — Property Loans
  • MSR scope: MSR 30% applies to HDB flats and ECs within MOP (MAS).
  • Variable & rental income: Variable income (bonus, commission, allowances) and rental income count at 70% — banks apply at least a 30% haircut (MAS Notice 645).
  • Joint tenure: Joint tenure uses the income-weighted average age of the borrowers, not the older borrower's age.
  • CPF interest: CPF OA interest is 2.5% p.a.; accrued interest on housing use compounds at that rate and must be refunded on sale. CPF Board — selling your property
  • Stamp duty: Buyer’s Stamp Duty tiers from IRAS. This calculator estimates BSD on residential rates and excludes ABSD. IRAS — Buyer’s Stamp Duty
  • Resale levy: HDB resale levy amounts by flat type apply to a second subsidised purchase. HDB — Resale Levy
  • Housing grants: only the total confirmed in your HFE letter is used, as HDB confirmed it (HFE letter valid 9 months). Grants are paid through CPF, not as cash in hand, and are not estimated here.
  • The 12× in 3/3/12: Median monthly household income was $12,446 in 2025 (SingStat, Key Household Income Trends 2025) and the median condo resale price was $1,710,000 in September 2026 (URA caveats via PLB Research) — $1,710,000 ÷ ($12,446 × 12) = 11.4× (11.45× to two decimals) annual income, rounded to a 12× target. It is a Singapore median to work towards, not a MAS rule and not a pass/fail gate.
  • TDSR & other debts: TDSR counts all monthly debt obligations, including car, personal, student loans and credit card minimum payments — MAS Notice 645. Other debts reduce TDSR room dollar-for-dollar. MSR counts housing instalment only.
  • Assumptions: Indicative only — other debts counted as entered above, variable and rental income counted at 70% with the tests run on the assessable income, first housing loan, tenure capped by the income-weighted average age (65 − weighted age, max 30 years, 25 years for HDB flats). Variable income is haircut 30% by banks, and LTV falls to 55% if tenure exceeds 30 years or runs past age 65.

Estimate only — not financial advice and not a loan approval. The TDSR / MSR figures are the regulatory ceilings; the one-third check is HomeAnalytics’ own advice, not a MAS rule. Your exact CPF refund is on cpf.gov.sg, your exact outstanding loan is on your latest statement, and a bank’s actual offer depends on its assessment, your age, tenure and valuation. Check those documents before you commit to any price.
