Step 1:

Open and edit the file /controllers/front/ProductController.php

– You may see line of code similar to this:

$combination_images = $this->product->getCombinationImages($this->context->language->id);
$combination_prices_set = [];

and add this code right after that line of code like photo:

$leo_current_selected_attributes = [];

– Next, find the line of code similar to this:

 

and add this code right after that line of code like photo:

if (isset($product_for_template['attributes'][$row['id_attribute_group']]['id_attribute']) && $product_for_template['attributes'][$row['id_attribute_group']]['id_attribute'] == $row['id_attribute']) {
$leo_current_selected_attributes[$row['id_attribute_group']] = $row['id_attribute'];
}

– Then find the line of code similar to this:

And add this code like photo:

$tax = (float) $this->product->getTaxesRate(new Address((int) $this->context->cart->{Configuration::get('PS_TAX_ADDRESS_TYPE')}));
$priceCurrent = DB::getInstance()->getValue('SELECT pa.`price`
FROM `' . _DB_PREFIX_ . 'product_attribute_combination` pac
INNER JOIN `' . _DB_PREFIX_ . 'product_attribute` pa ON pa.id_product_attribute = pac.id_product_attribute
WHERE id_product = ' . $this->product->id . ' AND id_attribute IN ('.implode(',', $current_selected_attributes).')
GROUP BY pac.id_product_attribute
HAVING COUNT(id_product) = ' . count($current_selected_attributes));
foreach ($groups as $id_attribute_group => &$rows) {
foreach ($rows['attributes'] as $id_attribute => &$row) {
if (!$row['selected']){
$attr_remove = $leo_current_selected_attributes[$id_attribute_group];
$attr_combi = array_diff($current_selected_attributes, [$attr_remove]);
$attr_combi[] = $id_attribute;
$price = DB::getInstance()->getValue('SELECT pa.`price`
FROM `' . _DB_PREFIX_ . 'product_attribute_combination` pac
INNER JOIN `' . _DB_PREFIX_ . 'product_attribute` pa ON pa.id_product_attribute = pac.id_product_attribute
WHERE id_product = ' . $this->product->id . ' AND id_attribute IN ('.implode(',', $attr_combi).')
GROUP BY pac.id_product_attribute
HAVING COUNT(id_product) = ' . count($attr_combi));
if ($price > $priceCurrent) {
$row['price'] = '+'.(Tools::displayPrice(($price - $priceCurrent)+($price - $priceCurrent)*$tax/100));
} else if ($price < $priceCurrent) {
$row['price'] = (Tools::displayPrice(($price - $priceCurrent)+($price - $priceCurrent)*$tax/100));
} else {
$row['price'] = '';
}
}
}
}

Step 2: Open and edit the file /themes/your_theme/templates/catalog/_partials/product-variants.tpl

Use this code to display the price (see photo):

{if isset($group_attribute.price) && $group_attribute.price}{$group_attribute.price}{/if}
