The UK now has among the highest property transaction taxes in the world.
In England or Northern Ireland you pay Stamp Duty Land Tax (SDLT), while in Scotland you pay Land and Buildings Transaction Tax (LBTT) and in Wales you will pay Land Transaction Tax (LTT).
This calculator will calculate the transaction tax on residential property purchases for investment.
Stamp Duty Land Tax (SDLT) is a key financial consideration in any property purchase across England and Northern Ireland. Paid by the buyer on residential and non-residential property transactions, SDLT can significantly affect overall affordability. Understanding how much stamp duty you will pay – and how it varies depending on the nature of the purchase – is vital for accurate budgeting and long-term planning.
To support informed decision-making, the PropertyData Stamp Duty Calculator offers a fast, reliable way to estimate your SDLT liability based on current UK thresholds. Whether you're a first-time buyer, landlord, company or overseas purchaser, our tool streamlines the process by delivering a clear breakdown of applicable tax bands and total costs, allowing you to plan with precision.
Stamp Duty Land Tax is calculated using a progressive system, where the tax is applied in brackets according to the portion of the property's price that falls within each band.
For example:
Different buyer profiles influence the rate of SDLT payable:
Several SDLT reliefs exist, including:
The combination of progressive tax rates and buyer category creates a complex landscape, making accurate calculations essential. That's where the PropertyData Stamp Duty Calculator becomes indispensable.
Our stamp duty calculator is designed for ease of use and accuracy. In just a few steps, you can obtain a clear and detailed estimate of your SDLT liability.
Your results will include:
Whether you're purchasing a £350,000 first home or a £700,000 investment property, the calculator dynamically adjusts to your circumstances – giving you clarity before you commit.
Stamp Duty thresholds are reviewed periodically by HMRC, and rates may change depending on government policy. As of the current 2025 guidance, the following rates apply:
| Property Price Bracket | Standard SDLT Rate |
|---|---|
| Up to £250,000 | 0% |
| £250,001 – £925,000 | 5% |
| £925,001 – £1.5 million | 10% |
| Over £1.5 million | 12% |
| Property Price Bracket | SDLT Rate (First-Time Buyers) |
|---|---|
| Up to £425,000 | 0% |
| £425,001 – £625,000 | 5% |
For non-residential or mixed-use properties, a different rate structure applies, which the calculator can accommodate.
For investors, SDLT can substantially increase acquisition costs, particularly on higher-value or multiple properties.
Using the PropertyData Stamp Duty Calculator allows investors to model different scenarios and assess cost-efficiency before committing to a purchase.

This is a real-time market snapshot - the data covers currently listed properties. Once properties are removed from the portal, they are soon removed from this tab.
How is the raw data processed?
Duplicates from multiple sources are matched and reconciled as far as possible. Listings with obvious errors, where price or number or bedrooms appear out of range, are discarded.
What are the statistics used?
Averages shown are the interquartile mean, a type of average that is insensitive to outliers while being its own distinct parameter. The 80% range means that 80% of the listed properties fall inside this range.

How do you know the square footage of properties?
We use proprietary technology to read the square footage of properties from agent floorplans. Although we cannot determine the square footage for all properties, we can usually get sufficient coverage. Agents are sometimes known to inflate square footage, and this should be borne in mind as a weakness of this data.

Where does the raw data come from?
Property "price paid" data provided by the Land Registry, and Energy Performance Certificate (EPC) data provided by Department for Levelling Up, Housing & Communities.
How do you know the square footage of properties?
We match the Land Registry data to EPC data provided by the Department for Levelling Up, Housing & Communities. Due to the fact that not all properties sold have had an EPC and vagaries of addressing in the UK, we are not able to determine the square footage of all properties, but we can usually get sufficient coverage.

How is the raw data processed?
Duplicates from multiple sources are matched and reconciled as far as possible. Listings with obvious errors, where price or number or bedrooms appear out of range, are discarded. Yields are calculated by comparing only properties with the same number of bedrooms, e.g. 3-bedroom properties for rent with 3-bedroom properties for sale.
What is the yield calculation used?
The calculation used is (average_weekly_asking_rent * 52 / average_asking_price), expressed as a percentage. It is a top-line gross yield, meaning no expenses are considered.
