Woocommerce custom price after actual price - woocommerce

Question

I'm in search for a function that could help me to add a custom price for my woocommerce (7.2.2 version) shop products. (Only as text in frontend). I'm using the yith membership to give the discount to my customers already, but I have no option to display discounted prices before the users can buy the membership.
Example:
My price is 2$ and I want to add the following text after price: 1$ with subscription x.
demo:
Product title
2$
1$ with subscription x
The function need to calculate the price with subscription x using the following fixed discount
original price - 50% = subscription price
Also this need to have some condition if the product already have a discount.
Product title
<del>2$</del> 1.8$
0,9$ with subscription x
I tried some modules which allowed me to add some text as current price suffix, but there is no way to do a calculation of the custom price using those modules.

Answer 1

Final solution : i added a 25% discount + custom text
function wptips_custom_html_addon_to_price( $price, $product ) {
$pretinitial = $price;
$sale_price = $product->sale_price;
if (!empty($sale_price)) {
$pretfinalscos = $sale_price;
}
else
{
$pretfinalscos = $pretinitial;
}
$pretfinal = preg_replace("/[^0-9,.]/", "", "$pretfinalscos");
$pretfinal = str_replace(',', '.', $pretfinal);
$pricegold = $pretfinal - ($pretfinal * (25 / 100));
$html_price_suffix = '<span style="color:black;" class="price-suffix"> <br>Cu abonamentul Gold '.number_format((float)$pricegold, 2, '.', '').' lei</span>'; // custom suffix html that you want to add after price
if ( !empty( $price ) ) {
$price = $html_price_prefix . ' ' . $price . ' ' . $html_price_suffix;
return $price;
} else {
return $price;
}
}
