# Simple Interest Calculator
](https://i1.sndcdn.com/artworks-bbhKX94ncwayTyEb-WNNpfQ-t500x500.jpg)
## Overview
Welcome to the **Simple Interest Calculator** — a lightweight and interactive Bash script designed to help you quickly calculate simple interest based on user input. This tool features a user-friendly menu, input validation, and a neat ASCII art banner to make your command-line experience more enjoyable.
---
## Features
* Interactive **menu-driven interface** for easy navigation
* Validates user inputs to ensure **positive and valid numbers**
* Calculates simple interest accurately with **decimal support**
* Clean and informative output display showing all inputs and results
* Built entirely in Bash — no additional dependencies except `bc` for floating-point arithmetic
* Lightweight and ideal for learning basic shell scripting and finance calculations
---
## How It Works
The script asks for three inputs from the user:
1. **Principal amount (P)** — The initial amount of money invested or loaned
2. **Annual rate of interest (R%)** — The yearly interest rate as a percentage
3. **Time period (T)** — The duration in years for which the money is invested or borrowed
Then it calculates the simple interest using the formula:
```
Simple Interest = (P × R × T) / 100
```
The result is displayed with a summary of the inputs for easy verification.
---
## Usage Instructions
1. Open your terminal or command line.
2. Navigate to the directory containing the `simple-interest.sh` script.
3. Make sure the script is executable by running:
```
chmod +x simple-interest.sh
```
4. Run the script:
```
./simple-interest.sh
```
5. Follow the on-screen prompts to enter principal, interest rate, and time.
6. Choose to calculate or exit using the menu options.
