Software Requirements Specification (SRS) for PF Calculator

Introduction

Purpose:

The purpose of this document is to outline the requirements for the development of a PF (Provident Fund) Calculator application. This application assists users in estimating the accumulated corpus and interest earned on Employee Provident Fund (EPF) contributions.

Scope:

The PF Calculator will provide users with a tool to project the future value of their EPF contributions. Users will input details such as their monthly contribution, duration, and interest rate, and the system will calculate and display the estimated accumulated corpus and interest earned.

System Overview

System Description:

The PF Calculator will be a web-based application accessible through a browser. It aims to empower users by providing insights into the growth of their EPF savings over time.

System Architecture:

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

Functional Requirements

Use Cases:

Calculate PF Accumulation:

• Users can input details such as monthly contribution, duration, and interest rate.
• The system will calculate and display the estimated accumulated corpus and interest earned on their EPF contributions.

Functional Requirements:

Input:

The system shall accept the following input:

• Monthly Contribution (in INR)
• Contribution Duration (in years)
• Interest Rate (in percentage)

Calculation:

• The system shall calculate the estimated accumulated corpus and interest earned based on the provided input.

Output:

• The system shall display the calculated accumulated corpus and interest earned 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 monthly contribution, contribution duration, and interest rate, along with a “Calculate” button.
• The calculated accumulated corpus and interest earned 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 PF 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 provident fund 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 PF 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 monthly contributions, contribution durations, and interest rates to ensure accurate PF calculations.

Test Case 1:

• Inputs: Monthly Contribution = 5,000 INR, Contribution Duration = 15 years, Interest Rate = 8%.
• Expected Output: Accumulated Corpus ≈ 16,14,086 INR, Interest Earned ≈ 9,14,086 INR

Test Case 2:

• Inputs: Monthly Contribution = 8,000 INR, Contribution Duration = 20 years, Interest Rate = 7.5%.
• Expected Output: Accumulated Corpus ≈ 28,24,396 INR, Interest Earned ≈ 20,24,396 INR

Test Case 3:

• Inputs: Monthly Contribution = 10,000 INR, Contribution Duration = 25 years, Interest Rate = 9%.
• Expected Output: Accumulated Corpus ≈ 72,86,216 INR, Interest Earned ≈ 62,86,216 INR

Acceptance Criteria:

The application is considered successful if it produces correct accumulated corpus and interest earned amounts based on the provided EPF contribution inputs.

Project Timeline

Milestones:
