The task

Arranging a mortgage involves many decisions. It can be difficult for people seeking financing to understand how the fixed-interest period, repayment rate or equity contribution affect their own financial planning. Baufi-Match is designed to put these parameters into context through comparable financing scenarios in a simple, responsive calculator.

Outcome

Baufi-Match gives people seeking a mortgage a concrete point of reference for decisions that are otherwise difficult to assess. The responsive calculator shows how people with similar personal and financial circumstances structured their mortgages. This makes abstract financing terms easier to understand through real-world benchmarks.

  • Each screen focuses on one clear, manageable question.
  • The visible size of the comparison group makes the basis of the results transparent.
  • The key financing terms are brought together in a clearly structured results overview.
  • Explanations and charts help users understand the terms and values in context.
  • The responsive design provides the same end-to-end flow on desktop and smartphone.
  • The results offer guidance for further mortgage planning rather than a standardized recommendation.
