Creating a Personal Budget App in Ruby


Developing a personal budget app in Ruby is a practical way to manage your finances, track expenses, and achieve your financial goals. In this guide, we'll explore the basics of creating a simple personal budget app using Ruby.


Before you start, make sure you have the following prerequisites:

  • Basic knowledge of the Ruby programming language
  • A code editor (e.g., Visual Studio Code, Sublime Text)
  • Terminal or command prompt access
  • A desire to manage your personal finances effectively

Step 1: Set Up Your Ruby Environment

Ensure you have Ruby installed on your system. You can check your Ruby version with:

ruby -v

If Ruby is not installed, you can download it from the official website ( and follow the installation instructions for your platform.

Step 2: Create Your Budget App

Let's create a simple budget app that allows you to track your income and expenses. We'll start with a command-line interface (CLI) application:

# Create a new directory for your budget app
mkdir budget_app
cd budget_app
# Initialize a new Ruby gem
bundle gem budget_app
# Define the gemspec file (budget_app.gemspec)
# Add gem dependencies to the gemspec file (e.g., 'highline' for user input)
# Create your budget app files (lib/budget_app.rb)
# Implement budget tracking logic
# Install required gems (highline)
bundle install
# Run your budget app
ruby -Ilib exe/budget_app

Step 3: Implement Budget Features

Implement budget features, including:

  • Income tracking
  • Expense tracking
  • Monthly budget summaries
  • Category-based expense tracking (e.g., groceries, utilities)

Step 4: Enhance the User Interface

Improve the user interface by creating a web-based or graphical user interface (GUI) for your budget app. You can use Ruby on Rails or other web development frameworks for this purpose.


Creating a personal budget app in Ruby is a practical way to gain control over your finances and meet your financial goals. This guide provides a starting point, and you can expand your app's features and user interface as needed. Effective budgeting is a valuable skill that can lead to better financial decisions and improved financial well-being.

Happy budgeting, and enjoy building your personal budget app!
