Stamp Duty Calculator
This calculator will produce a close estimate of the stamp duty you are required to pay in NSW.

This calculator gives a general estimate only.
It is not a loan offer, quote, pre-approval or lending commitment. Your actual borrowing capacity depends on a full credit assessment, individual lender policy, fees and your personal circumstances. This is not financial or credit advice. Speak with one of our mortgage brokers before signing anything.
How do you calculate stamp duty in NSW?
Stamp duty is based on your property’s purchase price (or market value, if higher), applied on a sliding scale set by Revenue NSW. Enter your price into the calculator for an instant estimate.
How much is stamp duty on a house in Sydney?
More than the NSW average, since Sydney property prices are higher. Enter your actual purchase price into the calculator for an exact figure.
Do first home buyers pay stamp duty in NSW?
Often not. Most first home buyers qualify for a full or partial exemption, depending on the purchase price and whether the property is new, established or vacant land.
