Understanding UK Mortgages
A UK mortgage is a loan secured against property in the United Kingdom, denominated in British Pounds (£). This calculator helps you estimate monthly payments, total interest, and additional costs like stamp duty, insurance, and property taxes. Whether you're buying your first home or remortgaging, understanding your monthly obligations is crucial for financial planning.
Mortgage Types in the UK
Repayment Mortgage
Each monthly payment covers both interest and a portion of the principal. By the end of the term, you've paid off the entire loan and own the property outright.
Pros: Guaranteed to pay off loan, builds equity faster
Cons: Higher monthly payments initially
Interest-Only Mortgage
Monthly payments only cover the interest; the principal remains unchanged. You must have a plan to repay the loan amount at the end of the term.
Pros: Lower monthly payments
Cons: Must repay full amount at end, more interest over time

Frequently Asked Questions
How much can I borrow for a UK mortgage?
UK lenders typically allow you to borrow 4-4.5 times your annual income. For example, with a £50,000 salary, you could borrow £200,000-£225,000. The exact amount depends on your income, credit score, existing debts, and deposit size. Some lenders offer up to 5.5x income for high earners or certain professions. A larger deposit (20%+) usually qualifies you for better rates.
What is stamp duty and who pays it?
Stamp Duty Land Tax (SDLT) is a tax paid by the buyer when purchasing property in England and Northern Ireland. It's calculated on a tiered system based on property value. First-time buyers get relief on properties up to £625,000 (no tax on first £425,000, then 5% on the portion up to £625,000). Scotland has Land and Buildings Transaction Tax (LBTT), and Wales has Land Transaction Tax (LTT) with different rates.
Should I choose a fixed or variable rate mortgage?
Fixed rate: Your interest rate and monthly payment stay the same for the fixed period (typically 2-5 years). Provides certainty and protection against rate rises, but you won't benefit if rates fall. Variable rate: Your rate can change based on the Bank of England base rate or the lender's standard variable rate (SVR). Can be cheaper initially but carries more risk. Most borrowers choose fixed rates for stability, especially when rates are low.
How much deposit do I need for a UK mortgage?
Minimum deposit is typically 5-10% of the property value, but larger deposits secure better rates. With a 5% deposit, you need a 95% LTV (loan-to-value) mortgage, which has higher interest rates and stricter criteria. A 10% deposit (90% LTV) opens more options. At 15-20% deposit, you access significantly better rates. The sweet spot is often 25% deposit (75% LTV) for the best rates and lowest monthly payments.
