Stamp Duty Calculator UK
Buying property involves several costs, and one of the most important is Stamp Duty Land Tax (SDLT). The Stamp Duty Calculator UK by Accotax helps homebuyers, landlords, investors, and businesses estimate how much stamp duty may be payable on a property purchase. Whether you are buying your first home, moving house, purchasing a buy-to-let property, or investing in commercial real estate, understanding your stamp duty costs before completion is essential for accurate budgeting.
Stamp Duty Formula (How It Is Calculated)
Stamp duty is charged in bands, meaning different portions of the purchase price are taxed at different rates.
Basic Formula:
Stamp Duty = Sum of tax charged within each price band
Example:
If a property costs £350,000:
- First portion taxed at 0%
- Next portion taxed at relevant rate
- Remaining balance taxed at higher rate band
The calculator automatically applies the latest rates and gives you an instant total.
