Enter your values to calculate your result.
Formula
0% up to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1,500,000, 12% above
SDLT is charged progressively, like income tax bands — only the portion of the price that falls within each band is taxed at that band's rate, not the whole price at the highest applicable rate.
Example
A £300,000 purchase: 0% on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the remaining £50,000 (£2,500) — a total of £5,000, an effective rate of about 1.67%.
Frequently Asked Questions
Does this apply in Scotland or Wales?
No — Scotland charges Land and Buildings Transaction Tax (LBTT) and Wales charges Land Transaction Tax (LTT), each with their own separate rates and bands. This calculator covers England and Northern Ireland's Stamp Duty Land Tax (SDLT) only.
I'm a first-time buyer — does this apply to me?
No — first-time buyers get relief (0% up to £300,000, then 5% up to £500,000) that this calculator doesn't model. You'd generally pay less than the standard rate shown here.
