What is loan-to-value (LTV)?
LTV is the size of your mortgage as a percentage of the property value. A lower LTV usually means access to better interest rates. For example, a 10% deposit gives you a 90% LTV.
What mortgage rate should I use?
Use the rate you've been quoted or check current average rates on our Mortgages page. As of May 2026, major lenders are offering 2-year fixes from around 4.5% depending on your LTV.
What is a repayment mortgage?
A repayment mortgage means your monthly payments cover both the interest and a portion of the loan itself, so by the end of the term your mortgage is fully paid off. This calculator uses repayment mortgages only.
How can I reduce my monthly repayments?
You can extend the mortgage term, save a larger deposit to reduce the loan amount, or find a lower interest rate. Be aware that extending the term increases total interest paid.
Does this include stamp duty?
No — use our Stamp Duty Calculator separately to work out that cost. Stamp duty is paid upfront and is separate to your mortgage.
