This Python-based application provides a simple graphical user interface (GUI) to calculate compound interest over time, displaying both numerical data and a graphical representation of the growth.
- Input principal amount, annual interest rate, time in years, and compounds per year.
- Calculate the future value of an investment based on the compound interest formula.
- Visualize the growth of the investment over time through an interactive graph.
Before you run the application, ensure you have Python installed on your system. Python 3.6 or higher is recommended. You can download Python from python.org.
Additionally, the application requires the following Python libraries:
customtkintermatplotlibnumpy
These will be installed in the next step
- Download / clone repository:

Upon running the application, you will see a GUI window. Enter the following information:
- Pincipal ($): The initial amount of money invested or borrowed.
- Annual Rate (%): The interest rate per year as a percentage.
- Time (years): The total number of years the money is invested or borrowed for.
- Compounds per Year: How often the interest is compounded per year.
After filling out the fields, click the "Calculate" button to see the future value of the investment and a graph depicting the growth over time. Move your mouse over the graph to see details about specific points in time
