THE SDLT CALCULATOR (England & Northern Ireland)
Enter the price and your buyer status — first-time buyer, standard
residential, or additional property / buy-to-let. You get:
• Stamp Duty payable
• Effective rate as a % of the price
• Total cost, price plus tax
• A full band-by-band breakdown, so you can see exactly where the tax lands
THE ADVANCED CALCULATOR
Every scenario across all three nations, computed for your price:
• England & NI — standard, first-time buyer, additional/BTL, and commercial
• Wales — main residence, higher rate (additional), and commercial (LTT)
• Scotland — standard, first-time buyer, additional including the 8% ADS,
and commercial (LBTT)
Plus the filing deadline after completion for whichever applies.
