What is Deal4Wheels Car Finance Calculator?

Deal4Wheels Car Finance Calculator is a UK-compliant, web-based finance estimation platform developed by Hudasoft for automotive marketplaces and dealerships. The system enables customers to calculate monthly repayments, APR, total payable amount, and finance eligibility for both Hire Purchase (HP) and Personal Contract Purchase (PCP) products. Designed in line with FCA regulations, the calculator replaces manual quotations and spreadsheet-based finance discussions with a transparent, digital, and customer-friendly experience, helping buyers make informed decisions before speaking with sales teams.
