This Python script implements a compound interest calculator, offering the following functionalities: Future value and installment calculation: Calculates the total value of a loan based on the initial value, number of installments and interest rate. Interest rate calculation: Calculates the interest rate required for an initial value to become a final value in a given period. Time calculation: Calculates the time required for an initial value to become a final value, considering a specific interest rate.
Run the script: Open your terminal or command prompt and run the Python script (for example, python calculator_interest.py). Choose the operation: The program will display a menu with the available options. Enter the data: Follow the instructions to enter the necessary values for each calculation. View the result: The result of the calculation will be displayed on the screen.
Interactive interface: The program guides the user through the calculation process, requesting the necessary data. Accurate calculations: The formulas used are the correct ones for calculating compound interest. Flexibility: Allows you to calculate different aspects of a loan, such as future value, interest rate and time.
The code is organized into functions that perform specific calculations: calculate_installment: Calculates the value of each installment of a loan. calculate_interest_rate: Calculates the interest rate needed to reach a certain future value. calculate_time: Calculates the time needed to reach a certain future value.
Python: Make sure you have Python installed on your system.
Graphical Interface: Create a graphical interface using libraries such as Tkinter or PyQt to make the program more user-friendly. Save Results: Allow users to save the results of the calculations to a file. Graphs: Add graphs to visualize the evolution of the investment value over time. Other Features: Implement other features related to finance, such as amortization calculation, annual effective rate (TEA) and other indicators.
Choose the operation:
- Calculate future value and installments
- Calculate interest rate
- Calculate time Enter the option number: 1 What is the total amount you want to finance? R$10000 What is the number of installments? 12 What is the interest rate per month? 1 The total financing amount will be: R$11268.25 The amount of each installment will be: R$939.02
Flexibility: Adapt this README.md to include specific information about your project, such as the author's name, creation date, etc. Technical details: If desired, add more details about the formulas used and the algorithms implemented. Examples: Include more usage examples to illustrate the different features of the program.
