## Introduction to FD Rate Calculation

In any banking project, accurately calculating Fixed Deposit (FD) rates is crucial for both developers and end-users. This tutorial will guide you through implementing a precise FD rate calculation feature using Java Swing Application Developement. By the end of this article, you will have a functional component that handles FD computations efficiently.

**Inorder to calculate the FD Rates follow the below conditions**

**Input your FD Rates**

FD Rate must be grater than 100,000.

below 100,000 no interest rates included.

if the FD Rate more than 100,000 include

following condition

**1. if the FD Rate more than 100,000**

include 4.75 interest rate

**2. if the FD Rate more than 500,000**

include 6.75 interest rate

**3. if the FD Rate more than 1000,000**

include 8 interest rate
