HTML:

<tbody>
  <tr>
    <td><input type="number" name="Interest" id="input2" class="form-control" value=""/></td>
    <td><input type="" name="tc" id="int_amount" class="formcontrol" value=""/></td>
  </tr>
</tbody>

Javascript:

document.getElementById('input2').onkeyup = function() {
    document.getElementById('int_amount').value = (this.value != '') ? 'Rs: ' + (parseInt(this.value)-25) : '';
}

Set the .value of the <input> element, not the .innerHTML

document.getElementById("int_amount").value  = "Rs:"+" "+Total;

Hope this helps you.

function calculate(interest){
  var vatti = interest.value;
  if (vatti != '') {
    var Total = vatti - 25;
      document.getElementById("int_amount").value = Total;
  }else{
    document.getElementById("int_amount").value = '';
  }
}
<table>
    <tbody>
	<tr>
	    <td><input type="number" name="Interest" id="input2" onkeyup="calculate(this)" onchange="calculate(this)" class="form-control" value=""/></td>
	    <td><input type="" name="tc" id="int_amount" class="formcontrol" value=""/></td>
	</tr>
    </tbody>
</table>
