Simple question... maybe?

Alright, I'm creating a "goal" calculator for Affiliates on my site. The situation is customers referred pay $100/mo for the service. I set a variable right now for the referred amount of customers (will later grab from database). I set this value to 3. The person enters their "goal amount per month" in dollars. I formatted it already to where if the percent value is > 100 then it stays at 100%. What I am having trouble doing. Let's say for instance, the customer inputs $301, it will return 3.01 customers. Is there a way if it's over >= .01 on the customer count then round up to the next number.  I'm sure it's simple but honestly I've been out of high school since 03 and my brain is farting!  Here's the code.

 

 if (isset($_POST['submit'])) {

    $referred = 3;

    // round the number entered
    $num = $_POST['goal'];
    $num = intval($num + .5);

    // figure out the amount of customers per month
    // each customer pays $100/mo and then round it
    $cust = $num / 100;
    //$cust = intval($cust + .5);

    // if the value is lower than $50, automatically one customer
    if ($num < 50 && $num != 0 ) {
        $cust = "1";
    }

    $percent = ($referred / $cust) * 100;
    $percent = number_format($percent,1);

    if ($percent >= 100) {
        $percent = "100";
    }

    //math
    echo "To get $".$num." a month, you will need to refer ".$cust." customer(s) to reach your goal. You are ".$percent."% there!";
}
