    double MonthlyInterestRate = AnnualInterestRate/1200;

    //Calculate monthly payment
    double monthlyPayment = loanAmount * MonthlyInterestRate / (1 - (Math.pow(1 / (1 + MonthlyInterestRate), NumOfYears * 12)));

    //calculate total payment
    double totalPayment = monthlyPayment * 12 * NumOfYears;

    //ouput of total, monthly, annual
    System.out.print("Interest Rate: \t" + AnnualInterestRate + (" Monthly Rate: \t") + monthlyPayment + " Total Payment: \t" + totalPayment);

    Welcome to the Forum! Please read this topic to learn how to post code correctly and other useful tips for newcomers.

    Recommend you check out the printf() method.

    See the printf() method or the DecimalFormat class for ways to format numeric data for printing.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
