Stampduty Calculator

The UK Stamp Duty Calculator helps buyers estimate the Stamp Duty Land Tax (SDLT) they may need to pay when purchasing a residential property in England or Northern Ireland. Enter the property purchase price and choose whether you are a first-time buyer, home mover or additional property buyer. You can also include the non-UK resident surcharge where applicable. The calculator shows the estimated Stamp Duty payable, effective tax rate and a breakdown of the relevant SDLT bands. This estimate can help you plan your home-buying budget before making an offer. Stamp Duty rules can vary depending on ownership history, residency, joint purchases, shared ownership and available reliefs. Updated Aug 1, 2026

UK Stamp Duty Calculator

Use our UK Stamp Duty Calculator to estimate the Stamp Duty Land Tax (SDLT) you may pay when buying a residential property in England or Northern Ireland.

Who Can Use the Calculator?

Enter the property purchase price and select your buyer type to calculate an estimated Stamp Duty amount. The calculator can provide estimates for:

  • First-time buyers who may qualify for Stamp Duty relief
  • Home movers buying or replacing their main residence
  • Additional property buyers, including second-home and buy-to-let purchases
  • Non-UK resident buyers who may need to pay the SDLT surcharge

What Your Result Shows

Your result shows the estimated Stamp Duty payable, the effective tax rate and how the purchase price is divided across the applicable SDLT rate bands. This can help you understand the tax cost before making an offer and prepare a more realistic home-buying budget.

Important regional difference: Stamp Duty Land Tax applies only to property purchases in England and Northern Ireland. Buyers in Wales normally pay Land Transaction Tax (LTT), while buyers in Scotland normally pay Land and Buildings Transaction Tax (LBTT).

Calculator disclaimer: This Stamp Duty Calculator provides an estimate for general planning purposes only. Your final SDLT liability may differ because of first-time buyer eligibility, joint ownership, previous property interests, trusts, inherited property, shared ownership, mixed-use property, residency status, reliefs or other circumstances. Tax rates and thresholds can also change. Confirm the final amount with your solicitor, licensed conveyancer, tax professional or HMRC before exchange and completion. You can also compare your result using the official HMRC Stamp Duty Land Tax Calculator.
