Software Requirements Specification (SRS) for RD (Recurring Deposit) Calculator

Introduction

Purpose:

The purpose of this document is to outline the requirements for the development of an RD (Recurring Deposit) Calculator application. This application helps users estimate the maturity amount and interest for recurring deposits.

Scope:

The RD Calculator will provide a user-friendly interface for individuals to input details about their recurring deposits, such as the monthly deposit amount, tenure, and interest rate. The system will then calculate and display the expected maturity amount and interest earned.

Definitions, Acronyms, and Abbreviations:

RD: Recurring Deposit

System Overview

System Description:

The RD Calculator will be a web-based application accessible through a browser, focusing on simplicity and accuracy in estimating maturity amounts and interest for recurring deposits.

System Architecture:

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