What Mortgage Calculator does

Mortgage Calculator is a browser-based tool designed for UK homeowners to explore mortgage options and understand various repayment scenarios before making borrowing decisions. Users input loan amount, interest rate, and loan term to generate monthly repayment estimates and detailed amortization schedules. The site supports multiple mortgage types, including repayment, interest-only, and mixed arrangements, allowing borrowers to see how different structures affect their monthly payments, total interest costs, and overall financial obligations. The platform includes additional decision-support features such as local house price comparisons, deposit comparisons, and overpayment calculators, all without requiring an account or payment. It also offers side-by-side term comparisons (e.g., 15 vs. 30 years) to help users understand the long-term cost implications of their choices.

Questions

Mortgage Calculator FAQ

Can I use this calculator for buy-to-let or commercial mortgages?
The tool is designed for residential mortgages and supports repayment, interest-only, and mixed arrangements, but it does not include specific inputs or outputs for buy-to-let or commercial loan structures.
Does the calculator include property taxes and insurance in the monthly payment?
The basic calculation shows principal and interest repayments only; property tax and home insurance are not factored into the monthly total, though the site offers separate local house price data for context.
How accurate are the amortization schedules compared to lender statements?
The schedules provide a representative breakdown of how payments are applied to principal and interest over the loan term, but actual lender statements may vary based on fees, payment timing, or rate changes.
Is there a limit to how many different loan scenarios I can compare at once?
Users can run multiple calculations by adjusting the loan amount, term, rate, or mortgage type, and the site offers side-by-side term comparisons, but each new scenario requires a fresh calculation entry.
