Software Requirements Specification (SRS) for EMI Calculator

Introduction

Purpose:

The purpose of this document is to outline the requirements for the development of an EMI (Equated Monthly Installment) Calculator application.

Scope:

The EMI Calculator will allow users to calculate monthly installment amounts for loans based on input parameters such as loan amount, interest rate, and loan tenure.

Definitions, Acronyms, and Abbreviations:

EMI: Equated Monthly Installment

System Overview

System Description:

The EMI Calculator will be a web-based application accessible through a browser. Users will input loan details, and the system will calculate the monthly installment.

System Architecture:

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