Access to information inside a loop

Hello,

I'm wondering how to access to information of specific fundrasing inside a loop ( ie list of fundraisings) to display small information like amount, total to reach etc ... in a loop like this

if (have_posts()) : while (have_posts()) : the_post();?>
<div class="box">
<?php the title();
the_post_thumbnail();
the excerpt();
...
and something like :
$fundraisingclass->amout();
$fundraisingclass->amout_to_reach();
etc ...

or why not show progresss bar ...

thx a lot

Fulgence
