汽車金融計算PHP

我想建立一個汽車金融計算器，我想通過顯示每個月的原則支付提高代碼和每個月的興趣，我有以下代碼汽車金融計算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>';

做什麼我想我需要使用公式此頁面 http://www.ifsautoloans.com/car-loan-interest/

這是公式

$ 100 $ 100 = 10％/ 12個月* $ 12,000）上。因此，第一次付款時，您將支付154.96美元[154.96美元= 254.96美元 - 100美元]。

我只是不明白，謝謝您的幫助
