Fixed deals end. We'll help you understand what's next.

UK rates are fixed for 2 or 5 years, then revert to your lender's standard variable rate — often much higher. The Mortgage Ledger helps you understand your numbers in plain language, without selling you anything.

This calculator is provided for illustration purposes only and does not constitute financial advice, a mortgage offer, or a recommendation of any specific product or lender. The interest rate shown is a national average sourced from the Bank of England — your actual rate will depend on your personal circumstances, credit profile, deposit, and chosen lender, and is likely to differ from the figure shown here.

Stamp Duty/LBTT/LTT and Council Tax/Domestic Rates figures are estimates based on published national rates and averages at the time of writing; actual amounts depend on your local authority and the specific details of your purchase. Always confirm exact figures with HMRC, Revenue Scotland, the Welsh Revenue Authority, or your conveyancer before relying on them.
