Key UK Mortgage Factors: Stamp Duty
The **UK Mortgage Calculator** estimates the monthly principal and interest (P&I) payment. Crucially, it also calculates the **Stamp Duty Land Tax (SDLT)**, which is the compulsory tax on property purchases in the UK and is a significant upfront cost.
Stamp Duty (SDLT) Calculation
Stamp Duty uses different thresholds (bands). This calculator uses the simplified standard UK residential rates:
| Property Value | SDLT Rate |
|---|---|
| Up to £250,000 | 0% |
| £250,001 to £925,000 | 5% |
| £925,001 to £1,500,000 | 10% |
| Above £1,500,000 | 12% |
Frequently Asked Questions (FAQ)
Why are UK mortgage payments calculated monthly?
UK mortgages, like most loans, are amortized. The total loan amount is spread into equal installments over the term, ensuring that each payment covers the interest accrued that month and reduces the outstanding principal balance.
