How to Use the Interest Rates Calculator
Follow this step-by-step guide to get accurate mortgage payment calculations
Enter Your Loan Amount
Input the total amount you plan to borrow. This is typically the property price minus your deposit. For example, if you're buying a £300,000 property with a £60,000 deposit, enter £240,000.
Set Your Interest Rate
Enter the annual interest rate offered by your lender. Current UK mortgage rates typically range from 4% to 7%. Check with multiple lenders to compare rates.
Choose Your Mortgage Term
Select the number of years over which you'll repay the mortgage. Common terms are 25, 30, or 35 years. Longer terms mean lower monthly payments but more interest paid overall.
Review Your Results
The calculator will show your monthly payment, total interest, and total repayment amount. Use these figures to budget and compare different mortgage options.
