Stamp Duty Land Tax (SDLT) rates shown are for England. Different rates apply in Scotland (Land and Buildings Transaction Tax) and Wales (Land Transaction Tax). The second home / BTL surcharge is an additional 5% on top of standard rates on each band. First-time buyers benefit from relief on properties up to £500,000 (0% on the first £300,000, 5% on the remainder). Repayment calculations assume a capital and interest mortgage with a fixed rate throughout the term. This calculator is for illustrative purposes only and does not constitute financial advice.
