Creating a Loan EMI Calculator application involves several key steps. Start by designing a simple yet intuitive user interface where users can input variables such as loan amount, interest rate, and tenure. Implement backend logic to compute the Equated Monthly Installment (EMI) using the appropriate formula. Ensure the application handles various types of loans (e.g., home loan, personal loan) and allows users to choose between different repayment frequencies (monthly, quarterly). Include features for displaying amortization schedules and total interest payable over the loan tenure. Test the application thoroughly to ensure accuracy and usability across different devices and screen sizes before deployment.
