README

A simple PHP-based Credit Calculator that supports three types of loan payment calculations:

  • Annuity Payments
  • Differentiated Payments
  • Bullet Payments

Features

  • Annuity Calculation: Fixed monthly payments throughout the loan period.
  • Differentiated Calculation: Payments decrease over time, starting with higher amounts.
  • Bullet Calculation: Payment method where the borrower only pays interest throughout the loan term, and the entire principal is paid in lump sum at the end of loan period.

Requirements

  • PHP 8.2 or higher

Installation

composer require artemind/credit-calculator

Usage

use Artemind\CreditCalculator\ResolverFactory;
use Artemind\CreditCalculator\Enums\CalculationType;

$resolver = ResolverFactory::createResolver(CalculationType::annuity);

$paymentSchedule = $resolver->resolve(6, 5000, 45);
