Software Requirements Specification (SRS) for Mutual Fund Returns Calculator

Introduction

Purpose:

The purpose of this document is to outline the requirements for the development of a Mutual Fund Returns Calculator application. This application helps users assess the historical returns on mutual fund investments, providing valuable insights into the performance of their investments.

Scope:

The Mutual Fund Returns Calculator will allow users to input details about their mutual fund investments, such as initial investment amount, investment duration, and historical growth rate. The system will then calculate and display the estimated returns on their investment.

System Overview

System Description:

The Mutual Fund Returns Calculator will be a web-based application accessible through a browser. It aims to assist users in evaluating the potential returns on their mutual fund investments based on historical growth rates.

System Architecture:

The application will follow a client-server architecture, with the client being the web browser and the server handling the returns calculation logic.

Functional Requirements

Use Cases:

Calculate Mutual Fund Returns:

• Users can input details such as initial investment amount, investment duration, and historical growth rate.
• The system will calculate and display the estimated returns on the mutual fund investment.

Functional Requirements:

Input:

The system shall accept the following input:

• Initial Investment Amount (in INR)
• Investment Duration (in years)
• Historical Growth Rate (in percentage)

Calculation:

• The system shall calculate the estimated returns based on the specified initial investment amount, investment duration, and historical growth rate.

Output:

• The system shall display the estimated returns on the mutual fund investment to the user.

Non-Functional Requirements:

• The system should provide a response time of under 3 seconds.
• The application should be accessible on common web browsers (Chrome, Firefox, Safari).

External Interface Requirements

User Interfaces:

• The user interface shall include input fields for the initial investment amount, investment duration, historical growth rate, along with a “Calculate” button.
• The calculated estimated returns shall be displayed prominently.

Hardware Interfaces:

• The system should be compatible with standard computing hardware.

Software Interfaces:

• The application shall be developed using HTML, CSS, and JavaScript.
• The server-side logic can be implemented using a backend framework (e.g., Node.js, Django).

Communication Interfaces:

• The application will communicate with the server for the returns calculation and display of results.

Performance Requirements

Response Time:

The system should respond within 3 seconds for a typical user input.

Throughput:

The application should handle at least 50 simultaneous users.

System Constraints

Regulatory Requirements:

The application should comply with relevant financial regulations.

Hardware Limitations:

The system should be compatible with devices with standard web-browsing capabilities.

Security Requirements

Authentication:

The application may or may not require user authentication, depending on whether users want to save their mutual fund returns calculation data.

Data Protection:

If authentication is implemented, user data should be stored securely.

Quality Attributes

Reliability:

The application should produce accurate results based on the provided input.

Maintainability:

The code should be well-documented for ease of maintenance.

Usability:

The user interface should be intuitive, requiring minimal guidance.

Testing Requirements

Test Cases:

Test cases should cover various scenarios with different initial investment amounts, investment durations, and historical growth rates to ensure accurate estimated returns calculations.

Test Case 1:

• Inputs: Initial Investment Amount = 1,00,000 INR, Investment Duration = 5 years, Historical Growth Rate = 10%.
• Expected Output: Estimated Returns ≈ 1,61,051 INR

Test Case 2:

• Inputs: Initial Investment Amount = 2,50,000 INR, Investment Duration = 8 years, Historical Growth Rate = 8%.
• Expected Output: Estimated Returns ≈ 4,43,968 INR

Test Case 3:

• Inputs: Initial Investment Amount = 5,00,000 INR, Investment Duration = 10 years, Historical Growth Rate = 12%.
• Expected Output: Estimated Returns ≈ 13,75,324 INR

Acceptance Criteria:

The application is considered successful if it produces correct estimated returns based on the provided initial investment amounts, investment durations, and historical growth rates.
