Faulty tax calculation


Recommended Posts



I am using Prestashop ( for a while now, but just recently noticed a problem in the tax calculation on the invoices. I tried explaining it in the image beneath.


In short:

The "Product total (tax included)" price on the invoices, seems to be different from the price we will get when we sum up the "Product total (tax excluded)" + "Total Tax". Both should even in the end.


The "Product total (tax included)" = €202,05

"Product total (tax excluded)" = €183,86 

"Total Tax" = €18,18


€183,86 + €18,18 = €202,04

€202,05 - €202,04 = €0,01


This shows a difference of €0,01. which is again different for every individual invoice.





I would be grateful if anyone could help me find the solution to this problem.

I can't seem to figure it out myself.
