Project Description
Understanding the true cost of a mortgage involves far more than calculating a monthly repayment. Interest rates, mortgage terms, deposits and fixed-rate periods all have a significant impact on the overall cost of borrowing.
UK Mortgage Calculator was developed to simplify mortgage planning by bringing together repayment calculations, mortgage comparisons and financial planning tools within a modern mobile application.
Built specifically for UK users, the app provides fast calculations, clear breakdowns and interactive comparisons that help users make informed decisions before committing to one of life's biggest financial investments.
The Challenge
Mortgage calculations can quickly become confusing when comparing different interest rates, repayment terms and fixed-rate deals.
Many online calculators provide only a single estimate, making it difficult for users to compare multiple scenarios or understand how small changes can affect the overall cost of a mortgage.
The objective was to create a dedicated mobile application that allows users to explore different borrowing options, compare repayments and better understand long-term mortgage costs through an intuitive, user-friendly interface.
The Solution
UK Mortgage Calculator combines powerful mortgage calculations with practical planning tools designed specifically for UK home buyers.
Key features include:
- Monthly mortgage repayment calculator
- Total interest calculations
- Loan-to-value (LTV) calculator
- Deposit planning
- Fixed-rate mortgage comparisons
- Mortgage term comparisons
- Overpayment calculator
- Save mortgage scenarios
- Mortgage comparison tools
- PDF export (Pro)
- Offline-first functionality
The app presents every calculation using clear summaries and visual breakdowns, helping users understand both short-term affordability and long-term borrowing costs.
