Circular percent progress bar

Considering the shape of the progress bar (rounded end/start) I would suggest using SVG.

DEMO: Radial progress bar

Radial progress bar

In the following example, the progress is animated with the stroke-dasarray attribute and the % numbers are incremented with jQuery:

var count = $(('#count'));
$({ Counter: 0 }).animate({ Counter: count.text() }, {
  duration: 5000,
  easing: 'linear',
  step: function () {
    count.text(Math.ceil(this.Counter)+ "%");
  }
});
body{text-align:center;font-family: 'Open Sans', sans-serif;}
svg{width:25%;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<svg id="animated" viewbox="0 0 100 100">
  <circle cx="50" cy="50" r="45" fill="#FDB900"/>
  <path fill="none" stroke-linecap="round" stroke-width="5" stroke="#fff"
        stroke-dasharray="251.2,0"
        d="M50 10
           a 40 40 0 0 1 0 80
           a 40 40 0 0 1 0 -80">
    <animate attributeName="stroke-dasharray" from="0,251.2" to="251.2,0" dur="5s"/>           
  </path>
  <text id="count" x="50" y="50" text-anchor="middle" dy="7" font-size="20">100%</text>
</svg>

Unfortunatly IE doesn’t support svg SMIL animations. To achieve the same result with IE support, you can use a library like snap.svg and animate the stroke-dasharray attribute with JS :

var count = $(('#count'));
$({ Counter: 0 }).animate({ Counter: count.text() }, {
  duration: 5000,
  easing: 'linear',
  step: function () {
    count.text(Math.ceil(this.Counter)+ "%");
  }
});

var s = Snap('#animated');
var progress = s.select('#progress');

progress.attr({strokeDasharray: '0, 251.2'});
Snap.animate(0,251.2, function( value ) {
    progress.attr({ 'stroke-dasharray':value+',251.2'});
}, 5000);
body{text-align:center;font-family:sans-serif;}
