This dashboard provides a comprehensive overview of loan approval data, highlighting key metrics and trends. The majority of loans, 77.77%, are approved, while 22.23% are rejected. The data is segmented by various factors, including home ownership status, education level, gender, age, and loan purpose. The most common loan purposes are debt consolidation (19%) and education (17%). The dashboard also shows the maximum interest rate (13.396%) and loan-to-income ratio (12.026), offering insights into the financial risk associated with the loans. Demographic factors such as gender, education, and age are analyzed to understand their impact on loan approvals. This visualization is useful for risk assessment, targeted marketing, and improving loan approval processes.
