README

A laravel package for calculating equal principal interest and equal principal repayment.

Installation

If you're using Composer to manage dependencies, you can use:

composer require zzzzzqs/repayment

Add service provider

Add the service provider to the providers array in the config/app.php config file as follows:

'providers' => [

    ...

    \Zzzzzqs\Repayment\RepaymentServiceProvider::class,
]

Publish the config

Run the following command to publish the package config file:

php artisan vendor:publish --provider="Zzzzzqs\Repayment\RepaymentServiceProvider"

You should now have a config/repayment.php file that allows you to configure the basics of this package.

Usage

// epc means: matching the principal repayment 
// etc means: average capital plus interest

public function __construct(PaymentCalculatorFactory $calculatorFactory)
{
    $this->calculatorFactory = $calculatorFactory;
}

public function calculate($type, $principal, $interestRate, $years)
{
    $calculator = $this->calculatorFactory->create($type, $principal, $interestRate, $years);
    return $calculator->getResult();
}

// param like this:
// $principal = 120000;
// $yearInterestRate = "0.0486";
// $year = 10;

// the result is a object like RepaymentDTO;
// if you want a array, you can $calculator->getSchedule return the new result like:
[
    1 => [
        "period" => 1
        "principal" => "1000.00"
        "interest" => "486.00"
        "total_money" => "1486.00"
    ],
    2 => [
        "period" => 2
        "principal" => "1000.00"
        "interest" => "481.95"
        "total_money" => "1481.95"
    ],
