The UK mortgage calculator works out your monthly repayment for a repayment or interest-only mortgage. Enter the loan amount in pounds, the annual interest rate, and the term in years to see the monthly cost. It uses standard UK mortgage amortization and is suitable for residential and buy-to-let calculations.
Repayment vs Interest-Only Mortgages
A repayment mortgage pays off both interest and principal each month so the loan is fully cleared at the end of the term. An interest-only mortgage pays just the interest, leaving the full principal outstanding at the end. Interest-only mortgages have lower monthly payments but require a separate repayment strategy for the capital.
UK Mortgage Rates and Types
Most UK mortgages use variable rates tied to the Bank of England base rate or fixed rates for 2, 5, or 10-year periods. After a fixed term, the mortgage moves to the lender's standard variable rate (SVR), which is usually higher. Remortgaging before the SVR kicks in typically saves money.
| Mortgage Type | Description |
|---|---|
| Fixed Rate | Rate locked for 2, 5, or 10 years |
| Tracker | Follows Bank of England base rate + margin |
| Standard Variable Rate | Lender's default rate, usually higher |
| Discount | Reduction off SVR for a set period |
Frequently Asked Questions
How much can I borrow in the UK?⌄
Most UK lenders offer 4-4.5 times annual income. Some lenders extend to 5-6 times for higher earners. Affordability checks also consider existing debts, monthly expenses, and stress-test rates.
What is stamp duty?⌄
Stamp Duty Land Tax (SDLT) is a tax on property purchases in England and Northern Ireland. Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT). Rates vary by purchase price and buyer type (first-time buyer, additional property).
Should I get a fixed or variable rate?⌄
Fixed rates give payment certainty and protection if rates rise. Variable rates benefit from rate cuts but expose you to payment increases. Choose based on your risk tolerance and outlook on interest rates.
