Our mortgage payment calculator UK uses the standard compound interest formula used by banks and building societies across the United Kingdom. Simply enter your property price, deposit amount, interest rate, and mortgage term to receive instant, accurate calculations.
The calculator determines your monthly payment using the mathematical formula that accounts for the principal loan amount, interest rate, and repayment period. For repayment mortgages, each monthly payment includes both capital repayment and interest charges, with the balance shifting over time as you pay down the loan.
Our tool is specifically designed for the UK market, incorporating British mortgage terminology, pound sterling formatting, and rate ranges typical of UK lenders. Whether you're a first-time buyer, remortgaging, or purchasing a buy-to-let property, our calculator provides reliable estimates to help you plan your finances.
