The Loan EMI Calculator is a web-based tool that helps users calculate their Equated Monthly Installments (EMI) for loans such as personal loans, home loans, car loans, or education loans. This application allows users to plan their finances by giving them a clear idea of the monthly repayment amount, total interest payable, and overall repayment schedule before applying for a loan.

Key Features

1. User-Friendly Input Form – Fields for loan amount, interest rate (annual), and loan tenure (in months/years).

2. Instant EMI Calculation – Calculates EMI using the standard formula:

   EMI=P×R×(1+R)N(1+R)N−1EMI = \frac{P \times R \times (1+R)^N}{(1+R)^N - 1}EMI=(1+R)N−1P×R×(1+R)N​

   where P = Principal, R = Monthly Interest Rate, N = Number of Months.

3. Amortization Schedule – Displays month-by-month repayment details including principal and interest portions.

4. Total Interest & Total Payment Display – Shows a breakdown of the total loan cost.

5. Multiple Loan Types – Option to select between personal, home, car, or education loans with pre-filled default rates.

7. Currency Support – Allows calculation in different currencies.

8. Responsive UI – Works on mobile and desktop using Bootstrap.

9. Data Saving Option – Registered users can save and compare multiple loan scenarios.
