How stamp duty on £1,800,000 is worked out
Here's the calculation for a home bought for £1,800,000. Each rate only applies to the slice of the price inside its band:
- 0% on £125,000 (up to £125,000) = £0
- 2% on £125,000 (£125,001 – £250,000) = £2,500
- 5% on £675,000 (£250,001 – £925,000) = £33,750
- 10% on £575,000 (£925,001 – £1,500,000) = £57,500
- 12% on £300,000 (over £1,500,000) = £36,000
Total stamp duty: £129,750, an effective rate of 7.21% of the purchase price.
