Create a plugin for that. So you need to create new module Or add following code into your existing module.


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Model\Config\Source\Product\Options\Price">
        <plugin name="sr_stackexchange_add_price_type" type="SR\StackExchange\Plugin\Catalog\Model\Config\Source\Product\Options\Price" sortOrder="1"/>


namespace SR\StackExchange\Plugin\Catalog\Model\Config\Source\Product\Options;

class Price
     * {@inheritdoc}
     * @codeCoverageIgnore
    public function afterToOptionArray(
        \Magento\Catalog\Model\Config\Source\Product\Options\Price $subject,
        array  $priceTypeOption
        $priceTypeOption[] = ['value' => 'new_type', 'label' => __('New Type')];
        return $priceTypeOption;

Clear magento cache.

  • One thing to note: When defining the value new_type in this instance it can only be a maximum of 7 characters Commented May 24, 2017 at 22:56
