Software Requirements Specification (SRS) for SIP Calculator
Introduction
Purpose:
The purpose of this document is to outline the requirements for the development of a Systematic Investment Plan (SIP) Calculator application.Scope:
The SIP Calculator will allow users to estimate future wealth accumulation based on input parameters such as monthly investment amount, expected annual return, and investment tenure.Definitions, Acronyms, and Abbreviations:
SIP: Systematic Investment PlanSystem Overview
System Description:
The SIP Calculator will be a web-based application accessible through a browser. Users will input investment details, and the system will calculate the future value of their investments.System Architecture:
The application will have a client-server architecture, with the client being the web browser and the server handling the calculation logic.Functional Requirements
Use Cases:
Calculate SIP:- Users can input the monthly investment amount, expected annual return, and investment tenure.
- The system will calculate and display the future value of the investment.
Functional Requirements:
Input:
The system shall accept the following input:- Monthly Investment Amount (in INR)
- Expected Annual Return (in percentage)
- Investment Tenure (in months or years)
Calculation:
The system shall calculate the future value of the investment using the SIP formula:- ��=�×(1+�)�−1�
- FV=P×
- r
- (1+r)
- n
- −1
-
- where:
- �
- P is the Monthly Investment Amount
- �
- r is the monthly interest rate (expected annual return divided by 12 and multiplied by 0.01 to convert percentage to decimal)
- �
- n is the total number of investments (monthly investments multiplied by the investment tenure in months)
Output:
- The system shall display the calculated future value to the user.
Non-Functional Requirements:
- The system should provide a response time of under 2 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 investment amount, expected annual return, and investment tenure, along with a “Calculate” button.
- The calculated future value 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 calculation and display of results.
Performance Requirements
Response Time:
The system should respond within 2 seconds for a typical user input.Throughput:
The application should handle at least 100 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 not require user authentication as it’s a public tool.Data Protection:
The system should not store or retain any user input data after the calculation.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 input scenarios to ensure accurate calculations.Test Case 1:
- Inputs: Monthly Investment Amount = 5,000 INR, Expected Annual Return = 10%, Investment Tenure = 60 months.
- Expected Output: Future Value ≈ 3,63,759.04 INR
Test Case 2:
- Inputs: Monthly Investment Amount = 10,000 INR, Expected Annual Return = 8%, Investment Tenure = 36 months.
- Expected Output: Future Value ≈ 4,08,368.09 INR
Test Case 3:
- Inputs: Monthly Investment Amount = 15,000 INR, Expected Annual Return = 12%, Investment Tenure = 48 months.
- Expected Output: Future Value ≈ 12,15,661.80 INR
Acceptance Criteria:
The application is considered successful if it produces correct future values based on the standard SIP calculation formula.Project Timeline
