Stamp duty (SDLT) calculator

What is a stamp duty calculator?

A stamp duty calculator helps you quickly estimate the Stamp Duty Land Tax (SDLT) you’ll need to pay when buying a property in England or Northern Ireland. By inputting details like property price and whether you're a first-time buyer, you can receive an accurate calculation of how much stamp duty you are estimated to pay based on current UK rules.

You can also take advantage of the other home-buying and renting calculator tools to further simplify the moving process. On top of calculating SDLT, you can get a better understanding of other associated costs by using our:

• Mortgage calculator
• Buy to let mortgage calculator
• Minimum rental income calculator
• Overpayment mortgage calculator

How to use our SDLT calculator

Ready to calculate your stamp duty? The process is straightforward and quick, providing you with an estimate in just a few minutes. Just input:

• Property purchase price: Your home's purchase price will determine how much stamp duty tax you accumulate. There are different rate bands, and the tax calculated depends on which one your property purchase price falls into. Homes costing up to £250,000 are exempt from stamp duty, although this exemption changes to £125,000 on 1 April 2025. As these tax bands are changing, check the most up-to-date ones.
• First-time buyer status: Up until 31 March 2025 those taking their first steps onto the property ladder will only pay stamp duty on homes over £425,000. (From 1 April, this will change to £300,000). For properties costing up to £625,000 (£500,000 from 1 April), first-time buyers will pay 5% on the portion above £425,000 (or £300,000 from 1 April). Purchases over £625,000 (£500,000 from 1 April) do not qualify for this relief. To benefit, you must have never owned a residential property before, either in the UK or abroad.
• Buyer residency status: If you are not a resident of the UK, you may need to pay an extra 2% on top of the stamp duty rates. This applies to properties over £40,000.
