About the UK Stamp Duty Calculator

Since 1 April 2025 SDLT is 0% up to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5 million and 12% above. First-time buyers pay nothing up to £300,000 and 5% from £300,001 to £500,000; above £500,000 the relief is lost.

Buying an additional residential property adds 5% to every band (for properties of £40,000 or more), and non-UK residents pay an extra 2%. Scotland (LBTT) and Wales (LTT) have their own taxes.

The formula

SDLT = Σ (price within each band × band rate)
