Amortizing Loan Calculator

This project is a C++ application that calculates the monthly payments and the amortization schedule for a loan. It uses basic arithmetic functions for multiplication and division and provides a detailed loan breakdown for each month.

Features

• Calculate monthly loan payments based on principal, interest rate, and loan duration.
• Generate an amortization schedule showing the breakdown of interest, principal payment, and remaining balance.
• Use custom functions for multiplication and division to perform the necessary calculations.

Prerequisites

Before you begin, ensure that you have the following installed on your machine:

• A C++ compiler (e.g., GCC, Clang, MSVC)
• CMake (for building the project)
• A modern C++ standard (C++17 or higher)

Getting Started

1. Clone the repository

   Clone this repository to your local machine using Git:

   https://github.com/kanyutu707/amortizingengine.git

2. Navigate to the project directory

   cd amortizingengine

3. Create a build directory

   It's recommended to create a build directory to keep the project organized.

   mkdir build
   cd build

4. Run CMake to generate the build files

   cmake ..

5. Build the project

   After generating the build files, compile the project:

   cmake --build .

6. Run the program

   Once the build is complete, you can run the application:

   ./amortizingengine

   The program will prompt you for the following inputs:

   • Principal amount
   • Interest rate (in percentage)
   • Loan duration (in years)

   It will then display the monthly payment and generate a loan amortization schedule showing the breakdown of each payment.

Code Overview

• multiplier.hpp and multiplier.cpp: Defines the multiplier function, which takes two numbers and returns their product. This function is used to calculate the total number of months for the loan.

• divisor.hpp and divisor.cpp: Defines the divisor function, which takes two numbers and returns the result of dividing the first by the second. This is used to calculate the interest and monthly payment breakdown.

• main.cpp: The main application logic. It reads input values from the user, performs calculations using multiplier and divisor, and then generates and prints the loan amortization schedule.

Example

Here is an example of how the program works:

Please enter the principal amount: 10000
Please enter the interest rate: 5
Please enter the years of loan: 5

Payment: 188.71
CM:    1   CI: 41.67   CP: 147.04   Bal:    9852.96
CM:    2   CI: 41.05   CP: 147.66   Bal:    9705.30
...
Loan payments complete

In this example:

• The loan principal is $10,000.
• The interest rate is 5%.
• The loan duration is 5 years (60 months).

The program calculates the monthly payment and prints out a breakdown of the interest and principal payments for each month, along with the remaining balance.
