Property calculators
The financial calculations from Unit 4, with every step shown so you can check your own working.
Buyer's Stamp Duty and ABSD
BSD is charged on the higher of the price or market value. ABSD has remissions and special cases (for example married couples, developers and trusts) that this calculator does not cover.
Seller's Stamp Duty (residential)
Uses the rates for residential property acquired on or after 4 July 2025 (4-year holding period). Property acquired earlier follows the older 3-year schedule.
Loan instalment, TDSR and MSR
TDSR and MSR are tested at the higher of your rate or the medium-term stress rate. LTV limits fall for longer tenures and for borrowers with existing housing loans.
Commission and GST
Commission is negotiable between the client and the estate agent. There is no fixed rate.
Rates last checked . Confirm against IRAS and MAS before relying on a figure.
