title: While Loops: my program is intended to show growth of a bank account with user input
body: <ol>
  <li><p>This is my code.</p>
  
  <pre><code>iBal = int(input('Enter your initial balance: '))
  aPer = int(input('Enter an annual interest percentage: '))
  fBal = int(input('Enter your desired final balance: '))
  sum1 = iBal*(1 + aPer/100)
  
  while sum1 &lt; fBal:
      print(format(sum1, '.2f'))
      sum1 = iBal*(1+aPer/100)
      iBal = sum1
  
  print(format(iBal, '.2f'))
  </code></pre></li>
  <li><p>This is what's returned, with user input (iBal=500, aPer=4, fBal=550)</p>
  
  <pre><code>&gt;&gt;&gt;520.00
  &gt;&gt;&gt;520.00
  &gt;&gt;&gt;540.80
  &gt;&gt;&gt;562.43
  </code></pre></li>
  <li><p>I need the first 520.00 to be 500.00 (the original inital balance entered), anyone see my mistake? Much appreciated.</p></li>
  </ol>
