자동차 금융 계산 PHP

나는 자동차 금융 계산기를 구축을 위해 노력하고, 내가 매달 원리 지불을 표시하여 코드를 개선하고자하는 각 달의 관심은, 내가 무엇을 할 수있는 다음 코드자동차 금융 계산 PHP

$interest = 10 /100/12;//10 is the interest rate 
$months = 60; //60 months term 
$loan = 12000;// total loan amount 

$monthly_payment = $loan * $interest/(1-(pow((1+$interest),-$months))); 
$total_payable = $monthly_payment * $months; 
$total_interest = ($total_payable - $loan); 

echo "Monthly Payment = " . $monthly_payment. '<br>'; 
echo "Total Payable = " . $total_payable . '<br>'; 
echo "Total Interest = " . $total_interest . '<br>'; 
echo "Monthly Interest = " . ($total_interest/$months) . '<br>';

이 난이 페이지는 포뮬러

$ 100 $ 100 = 10 %/12개월 * $ 12,000)이다 http://www.ifsautoloans.com/car-loan-interest/

에 수식을 사용해야 할. 결과적으로, 첫 번째 지불금으로 원금 $ 154.96 [$ 154.96 = $ 254.96 - $ 100]를 지불하게됩니다.

난 그냥 내가하고 싶은 것은이 링크와 동일한 도움

주셔서 감사합니다, 그것을 이해하지 못하는 내가 당신에게 빠른 PHP를주는거야
