Show Adjuster Amount Only in Commerce
You can access each adjuster and its respective amount via the cart.adjustments tag. Here's the example supplied with the templates from the commerce plugin (commerce/cart.html):

{% for adjustment in cart.adjustments %}
    &lt;tr&gt;
        &lt;td&gt;{{ adjustment.type }}
        &lt;/td&gt;
        &lt;td&gt;&lt;strong&gt;{{ adjustment.name }}&lt;/strong&gt;&lt;br&gt;({{ adjustment.description }})&lt;/td&gt;
        &lt;td class="text-right"&gt;{{ adjustment.amount|currency(cart.currency) }}&lt;/td&gt;
    &lt;/tr&gt;
{% endfor %}


If you have set the included attribute of your Adjuster to true then it won't show up as an adjuster but only affect the cart amounts outputted (such as baseShippingCost and baseDiscount) so if you have something similar to the above already, that's why it won't be displayed. You can read more about the included attribute here.
