monthlypay= (5/100) * Payment;

while(Payment > 0)  {

MonthsInterst = Interst/12;
MonthInterst= ((MonthsInterst/100)* Payment);

TotalInterst = TotalInterst + MonthInterst;
MonthlyNetPay = monthlypay - MonthInterst;
Payment = Payment - MonthlyNetPay;

if (MonthlyNetPay >= Payment) {
FinalPayment = Payment;
