update your while loop as below & echo $totalInc at the end of this while() loop
<?php
$totalInc = 0; //added this variable
while ($row=mysql_fetch_array($result)){
echo "<tr>";
echo "<td bgcolor='#FFFFF'>" . $row['t_id'] . "</td>";
echo "<td bgcolor='#FFFFF'>" . $row['dep_code'] . "</td>";
echo "<td bgcolor='#FFFFF'>" . $row['subdep_code']." ".$row['type_code'] . "</td>";
echo "<td bgcolor='#FFFFF'>" . $row['TER']. "</td>";
echo "<td bgcolor='#00FF33'>" . round(($row['TER']/570)*$pre). "%</td>";
echo "<td bgcolor='#FFFF00'>" . round($row['geff1']) . "%</td>";
echo "<td bgcolor='#FFFFF'>" . $row['tdate'] . "</td>";
if($row['geff1']>=105){
$inc=(300*($row['TER']/570)*$pre)/105;
}elseif($row['geff1']>=100){
$inc=(275*($row['TER']/570)*$pre)/100;
}elseif($row['geff1']>=95){
$inc=(240*($row['TER']/570)*$pre)/95;
}elseif($row['geff1']>=90){
$inc=(200*($row['TER']/570)*$pre)/90;
}elseif($row['geff1']>=85){
$inc=(160*($row['TER']/570)*$pre)/85;
}elseif($row['geff1']>=80){
$inc=(120*($row['TER']/570)*$pre)/80;
}elseif($row['geff1']>=75){
$inc=(90*($row['TER']/570)*$pre)/75;
}elseif($row['geff1']>=70){
$inc=(60*($row['TER']/570)*$pre)/70;
}elseif($row['geff1']>=65){
$inc=(30*($row['TER']/570)*$pre)/65;
}elseif($row['geff1']<65){
$inc=0;
}
$totalInc = $totalInc + $inc; //set value to this variable
echo "<td ><strong>Rs.".round($inc,2);"</strong></td>";
echo "</tr>";
