## Key figures at a glance

| Fact | Value | Source |
| --- | --- | --- |
| Maximum loan (first housing loan) | 75% of price or valuation — So at least 25% comes from your own cash and CPF. | [MAS / HDB](https://www.mas.gov.sg/regulation/explainers/new-housing-loans/loan-tenure-and-loan-to-value-limits) |
| Buyer's Stamp Duty | 1% to 6%, progressive — $24,600 on the first $1 million. | [IRAS](https://www.iras.gov.sg/taxes/stamp-duty/for-property/buying-or-acquiring-property) |
| ABSD on a Singapore Citizen's second home | 20% — $320,000 on a $1.6 million condo. | [IRAS](https://www.iras.gov.sg/taxes/stamp-duty/for-property/buying-or-acquiring-property) |
| CPF accrued interest | 2.5% a year on CPF used — Refunded to your CPF, with the principal, when you sell. | [CPF Board](https://www.cpf.gov.sg/member/home-ownership) |
| Seller's Stamp Duty (private homes) | 16% · 12% · 8% · 4% — If sold in years 1–4 after purchase (from 4 Jul 2025). | [IRAS](https://www.iras.gov.sg/taxes/stamp-duty) |
| HDB minimum occupation period | 5 years — Longer than the SSD window, so SSD rarely applies to HDB flats. |  |

## Costing a purchase from offer to sale: step by step

Run these in order. Each step adds a block of costs that a simple mortgage calculator leaves out.

1. **Upfront cash and CPF** (Before the offer) — Downpayment (cash and CPF), BSD, ABSD if any, legal and conveyancing fees, valuation, and any cash over valuation. Tools: [Singapore Buyer’s Stamp Duty Calculator](https://toolsg.com/en/bsd-stamp-duty-calculator), [ABSD Calculator Singapore](https://toolsg.com/en/absd-calculator), [HDB Affordability Calculator (MSR & TDSR)](https://toolsg.com/en/hdb-affordability-calculator)
2. **Moving-in costs** (Before key collection) — Renovation, furniture and appliances. Renovation is real spending that you rarely recover at resale. Tools: [HDB Renovation Loan Calculator](https://toolsg.com/en/hdb-renovation-loan-calculator)
3. **Running costs every year** (While you own it) — Interest on the loan, maintenance or conservancy charges, property tax on the Annual Value, home and fire insurance, and repairs.

4. **The hidden cost of CPF** (Throughout) — Every dollar of CPF OA used stops earning 2.5% a year, and you must refund principal plus that interest to CPF when you sell. Tools: [CPF Contribution Calculator](https://toolsg.com/en/cpf-calculator)
5. **Selling costs and break-even** (Before you buy) — Agent commission plus GST, legal fees and any Seller's Stamp Duty. The calculator works out the price you need at 5 and 10 years just to break even.

## Why the instalment is not the cost

A mortgage calculator answers "what will I pay each month?". That number leaves out three things that decide whether a purchase makes financial sense:

1. **Money that leaves before you get the keys** — stamp duties, fees and renovation.
2. **Money that keeps leaving** — interest, maintenance, property tax and insurance.
3. **Money you give up** — the CPF interest you stop earning, which you must repay to CPF when you sell.

## The four blocks of cost

| Block | What is in it | Cash or CPF |
| --- | --- | --- |
| Upfront | Downpayment, BSD, ABSD, legal fees, valuation, cash over valuation | Mix; ABSD and COV usually cash first |
| Moving in | Renovation, furniture, appliances | Cash or renovation loan |
| Yearly | Loan interest, maintenance/conservancy, property tax, insurance, repairs | Mostly cash; instalments can use CPF |
| Selling | Agent commission + GST, legal fees, Seller's Stamp Duty | From proceeds |

The **principal** part of each instalment is not a cost — it converts cash into equity — so the calculator shows it separately as forced savings. **Interest** is money gone.

## CPF accrued interest, explained

When you use CPF Ordinary Account savings for a home, that money stops earning 2.5% a year in CPF. CPF keeps a running total of the interest it would have earned — the **accrued interest**. When you sell, the principal **and** the accrued interest go back into your CPF account before you receive any cash.

Using $200,000 of CPF at the start of a ten-year holding period builds up about **$56,000** of accrued interest. On a flat that rose only a little in value, that refund can absorb the whole paper gain — the money is still yours, but it is back in CPF, not in your bank account.

> **Tip:** Accrued interest is not a penalty; it protects your retirement savings. But it means a "profit" on paper can leave you with little cash to put towards the next home.

## The break-even price

The calculator works out the **sale price at which you get back everything you put in** — downpayment, stamp duties, fees, renovation, interest and running costs, plus the outstanding loan and the CPF refund — after selling costs and any rent received. It then converts that into the yearly price growth the property must achieve over 5 and 10 years.

If breaking even in five years needs 3.4% growth a year and similar homes have been rising 1% a year, the purchase only works as a long-term home, not a short-term investment.

## Example: a $1.6 million condo as a second home

A Singapore Citizen who already owns a home pays **$49,600 BSD** and **$320,000 ABSD** (20%), plus legal fees and renovation. If they still have a housing loan on the first home, the new loan is capped at 45% LTV and at least 25% of the price must be paid in cash. The ABSD alone needs years of price growth to recover.

## Common mistakes

- **Counting principal as a cost** — or ignoring interest as one.
- **Forgetting ABSD** on a second property.
- **Ignoring CPF accrued interest** when estimating sale proceeds.
- **Selling a private home within 4 years** and triggering Seller's Stamp Duty.
- **Treating renovation as an investment** — it rarely adds its cost to the sale price.

## Frequently asked questions

**Why does CPF accrued interest matter so much?**

Because it is refunded to your CPF before you see any cash. If you used S$200,000 of CPF over ten years, roughly S$56,000 of accrued interest builds up on top of it. On a flat that only appreciated slightly, the entire paper gain can end up going back into CPF instead of your bank account.

**Is the loan principal a cost?**

No. The principal portion of your instalment converts cash into equity in the property, so this calculator excludes it from the true monthly cost and shows it separately as forced savings. Interest, on the other hand, is money gone for good.

**How is the break-even price calculated?**

It is the sale price where your net proceeds, after selling agent commission with GST, legal fees and any Seller's Stamp Duty, exactly cover the outstanding loan, everything you paid in, and the CPF accrued interest you must refund. Any rental income you received reduces it.

**Do I pay ABSD on an HDB BTO flat?**

ABSD depends on how many residential properties you own, not on whether the flat comes from HDB. A citizen buying a first home pays no ABSD. If you own another property you must generally dispose of it, and HDB eligibility rules apply on top of the tax rules.

**Why does my property tax change when I rent the unit out?**

Owner-occupier rates start at 0% and are heavily subsidised. Once the whole unit is let out, non-owner-occupier rates apply, starting at 12% of annual value. For a condo this can add several thousand dollars a year.

**Does this apply to Seller's Stamp Duty on HDB flats?**

HDB flats are subject to the 5-year Minimum Occupation Period, which is longer than the 4-year SSD window, so SSD does not normally apply in practice. The calculator sets SSD to zero for HDB and warns you if you plan to sell before the MOP ends.

**Are the rates in this calculator current?**

They reflect BSD rates from 15 February 2023, ABSD rates from 27 April 2023, owner-occupier property tax bands from 1 January 2025, the Seller's Stamp Duty schedule from 4 July 2025, and the 2.6% HDB concessionary rate. Always confirm with IRAS, HDB and CPF before you commit.
