Buying a property is an exciting milestone, but it also comes with financial responsibilities. One significant cost that every property buyer in the UK must consider is stamp duty (also known as property transfer tax). Calculating stamp duty manually can be complicated because rates vary depending on property price, buyer status, property type, and region.

Our Mortgage Stamp Duty Calculator simplifies this process. With just a few inputs, you can determine the exact stamp duty, effective tax rate, and total purchase cost, ensuring you budget properly for your new home.

What is Stamp Duty?

Stamp duty is a tax imposed by the government when you purchase a property. The rate depends on the property’s value and your buyer profile. For example:

First-time buyers may qualify for relief or lower rates.
Home movers usually pay standard rates.
Buy-to-let investors or additional property buyers may face a surcharge.

Rates differ across England, Wales, and Scotland, and additional fees like legal charges and surveys should also be considered.
