Show an inclusive tax

Hello, could someone direct me on how to show a tax of 12.5% that is already included in the product price, it can be on the total not on each item. Here in New Zealand we have a tax on all goods called GST that is 12.5%

EXAMPLE: $100 total
The gst on this is $12.50
How do I show this $12.50 without adding it to the $100

Thanks for any help

In the cart object, create a new calculation named "GST" as:
([Price] * [Quantity]) * 0.125


Where you want to display this, add:
<?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->TotalColumn("GST")); ?>

where "$eCart1" is the name of your cart

Thanks Jason

You're welcome.

Hi, I'm still having trouble showing the gst(the tax in my first post).

I have uploaded a zipped folder with a screen shot of the calculation & one of the code in the view cart where I think it should be. Could you elaborate on what I'm doing wrong. In the screen shot my cart is called '$cartOnlineMC' & the code is highlighted where I'm trying to show it.

Are any of the tax rules showing?

You have placed the code in a region of the page that will only be displayed if there is a rule from the tax tab that is showing.

Hi Jason, I have moved the code out of this area & presto the gst is showing. But is there a way to show this as a tax? I have no other tax rules as I don't require them. Sorry that I'm sounding like such a beginner but I'm just getting used to eCart & finding my way in the dark, & I have been reading the pdf files but finding it a little confusing.

Again thanks for the help. Chris

Sure, you could create a rule on the tax tab so it is displayed.


Use the trigger:
subtotal For Any Column:
if the subtotal of column "GST" is ">" a value of "0"


and the calculation:
based on column Subtotal:
Subtotal of Column "GST" "Plus" "0"

Do I keep the gst calculation I added earlier(I have) as when I get to the last bit in tax area that you said to do

"and the calculation:
based on column Subtotal:
Subtotal of Column "GST" "Plus" "0""

GST doesn't exist in the dropdown menu yet it does exist in the first dropdown menu.

I have changed the calculation

From "GST" as: ([Price] * [Quantity]) * 0.125

To "GST" as: ([Price] * [Quantity]) /9

as it was adding the gst to the total & 12.5% works out to be a ninth when inclusive.

But as I said above the GST only shows in the condition area dropdown menu & doesn't show in the calculation area dropdown menu.

So I have used "Based on column subtotal" 'subtotal of column' "price" - it now shows the GST correctly(well sort of) but the total price now shows double the amount in my page.

For example it shows. One item subtotal of $19.95 then GST of $2.22 this is correct
then the total is $39.90 which is double & incorrect.

Any other ideas?
