Calculation problem if more then 1 product in cart

Hey @sandras21

This appears to be a rounding issue. Can you change the setting for Rounding (under WooCommerce → Settings → Tax) and see if that makes a difference?

I tried it both way, rounding activated there and without, result is same, 2×3,88=7,75 not 7,76. decimal places is set 2. VAT amount is correct.

I got the first case to work by entering the price as ￡3.88 and setting “No, I will enter prices exclusive of tax”.

For 2 @ ￡5.44, I’m getting ￡10.88 + ￡2.18 tax @ 20%, again with prices entered exclusive of tax.

If I look from orders it looks that woocommerce is still calculating prices 4 decimals, for example:
6,26 – the price without vat is 5,2166 (if calculating based on 4decimals) and in case of 3 items the sum will be 15,65 (or 15,6499 in case of 4 decimals)
if rounded to 2 decimals as 5,22 the sum will be 15,66 (bookkeeping)
In the currency settings I have set it to 2 decimals but seems that calculations are still based on 4 and no rounding applied.
We need to display prices with vat, so vat excluded version is also not a solution unfortunately.
Is there any snippets or workarounds to create that rounding?

We need to display prices with vat, so vat excluded version is also not a solution unfortunately.

Its possible to enter prices excluding VAT and use the separate settings on the tax sub-page to display prices in the shop including tax and on the cart and checkout pages including tax.

I used the below snippet for a particular case, so it may not be suitable for you but I offer it as a starting point. It adds 1 to tthe total, then rounds.

add_filter( 'woocommerce_calculated_total', 'custom_calculated_total' );
function custom_calculated_total( $total ) {
  $total = round( $total, 1 );
  return $total;
}

Howdy.

We haven’t heard back from you in a while, so I’m going to go ahead and mark this thread as resolved. If you have any other questions please start a new thread.

Cheers!
