Yes I did! Using jQuery and WP Rest API I sent the Post Object ID to functions.php where I got and returned the price to jQuery.

Thanks for the reply. Got it working now 🙂
jQuery(".acf-repeater .acf-row").each(function(i, element) {
var row = $(element);
var orderrow_quantity = row.find(".orderrow-quantity input").val();
var orderrow_price_before_tax = row.find(".orderrow-price-before-vat input").val();
var orderrow_total_before_tax = orderrow_quantity * orderrow_price_before_tax;
var orderrow_total_after_tax = orderrow_total_before_tax * vat_percentage;
row.find(".orderrow-total-before-vat input").val(orderrow_total_before_tax);
row.find(".orderrow-total-after-vat input").val(orderrow_total_after_tax);
});
