| First-time buyer | £6,500 | 1.51% |

2. How the £11,500 is worked out
Stamp duty is marginal: each slice of the price is charged at the rate for its own band, not the whole price at one rate. For £430,000 the standard working is:
| Band | Rate | Taxable slice | Tax |
|---|---|---|---|
| £0 to £125,000 | 0% | £125,000 | £0 |
| £125,000 to £250,000 | 2% | £125,000 | £2,500 |
| £250,000 to £430,000 | 5% | £180,000 | £9,000 |
The bill is the sum of the Tax column, £11,500. That is an effective rate of 2.67% of the price.
3. First-time buyer stamp duty on £430,000
A first-time buyer pays £6,500 (nil up to £300,000, then 5% to £500,000). That saves £5,000 against the standard rates.
4. Second home or buy-to-let on £430,000
The higher rates add 5% to every band, so the same purchase as an additional residential property costs £33,000, which is £21,500 more than a main home. The surcharge applies when you buy a residential property for £40,000 or more and still own another one at the end of the purchase day. If you are replacing your main home you may be able to reclaim the surcharge: see our guide to stamp duty on a second home or buy-to-let.
| Band | Rate | Taxable slice | Tax |
|---|---|---|---|
| £0 to £125,000 | 5% | £125,000 | £6,250 |
| £125,000 to £250,000 | 7% | £125,000 | £8,750 |
| £250,000 to £430,000 | 10% | £180,000 | £18,000 |
5. What a little more or less would cost
Each extra £10,000 on the price adds about £500 of stamp duty at this level (the marginal rate is 5%). Moving from £430,000 to £455,000 would raise the main-home bill from £11,500 to £12,750, a difference of £1,250.
