Singapore property calculators
Buying: stamp duty, the cash and CPF you need, how much you can borrow and what the loan costs a month. Selling: what you keep. Every rate is read from our versioned rules, dated and sourced to IRAS, MAS and CPF.
Buying
Stamp duty calculator
Buyer's stamp duty and additional buyer's stamp duty together, for any price and buyer.
Cash and CPF needed to buy
The upfront bill: minimum cash, the rest in CPF or cash, stamp duty and legal fees, after the loan.
How much can I borrow? TDSR and LTV
Loan-to-value, total debt servicing and mortgage servicing limits, and the lower of them.
Mortgage repayment calculator
Monthly instalment, total interest over the tenure, the balance year by year, and the stress-test instalment.
HDB grant calculator
The Enhanced CPF Housing Grant, the Family or Singles Grant, and the Proximity Housing Grant, added up.
HDB resale levy calculator
What you pay on a second subsidised flat: the fixed amount by flat type, or the graded levy for a first flat sold before the fixed-levy date.
Selling
Net proceeds on sale
What you keep after seller's stamp duty, commission, legal fees, the loan and the CPF refund.
Owning
Property tax calculator
Annual property tax from an annual value: owner-occupied and non-owner-occupied bands, or the flat rate for non-residential property.
Buying or holding a particular home? Enter its postal code for an indicative value, and the same figures worked out on that value.
In Claude or ChatGPT
These calculators, the valuation and the site search are also an MCP server at https://homequant.ai/mcp. Add it as a custom connector in Claude or ChatGPT and ask in plain words; the assistant calls the same figures and links back here. No sign-up or key.
Indicative figures only, not tax, legal or financial advice. Confirm stamp duty with IRAS and loan limits with your bank or HDB before you commit.
