UK Stamp Duty Calculator

This tool estimates your Stamp Duty Land Tax (SDLT) liability for residential property purchases in England and Northern Ireland. It automatically applies the complex tiered SDLT bands based on your property price and buyer status.

Prospective home buyers, property investors, and current homeowners planning to move. It is an essential planning step to ensure you have enough cash for completion dates on top of your deposit.

Use this tool to calculate your exact moving costs before finalizing your budget. After estimating your tax, you can use our mortgage affordability calculator to see what property value you can realistically target.

Select the correct buyer status, as first-time buyer relief and the additional property surcharge drastically alter your final tax bill. Remember to verify the current GOV.UK rates, as bands can change during government budgets.

A major pitfall is forgetting to factor SDLT into your overall home buying budget, leading to cash shortfalls at completion. Also, carefully evaluate whether entering the market now makes sense by reading our renting vs buying home guide.

Calculating Stamp Duty can be confusing with progressive bands. We instantly compute your liability in your browser, keeping your data private while you pair it seamlessly with our mortgage calculator and rent vs buy calculator.
