Updated 5 Oct 2026 in Property & HDB

Calculates Buyer's Stamp Duty on a Singapore residential property using the tiered rates from 1% to 6%.

Property is the largest purchase most Singaporeans make, and stamp duties, loan limits and cash requirements are front-loaded. Small mistakes in these figures can mean a shortfall at completion, so it pays to run the numbers before you commit to an option to purchase.

Background

Beyond the price, buyers should budget for legal fees, valuation, home insurance, renovation and furnishing. Running the figures in advance helps you decide how much cash to hold back and whether a smaller loan or longer tenure makes more sense.

Singapore's property market is shaped by cooling measures introduced since 2009, including Additional Buyer's Stamp Duty, loan-to-value limits and debt servicing ratios. These rules are adjusted when the market runs hot, so the numbers you see today may differ from what friends paid a few years ago.

Stamp duties are paid upfront. Buyer's Stamp Duty applies to every purchase at tiered rates up to 6%, while ABSD depends on the buyer's residency status and how many residential properties they already own. Sellers who dispose of a property within the holding period pay Seller's Stamp Duty.
