How to get product price from variable product in WooCommerce?

Question

I done simple popup where you can see price of product with installment. It work fine. But on variable product it gives only the minimal price of product. Of course I want to get a price of product which I choose. Please help!

    <?php
       $product = wc_get_product( get_the_id());
       if(!empty($product)){
       $price = $product->get_price();

        $deadline = 12;
        $rate = 25;

        $rate_sum = ($price/ 100) * $rate;
        $total_sum = $price+ $rate_sum;
        $base_per_month = $total_sum / $deadline;
} else {
        echo "product is empty" ;
};
            
?>

Variable product prices are different because a variable product can have different variations prices, so you can get the minimal price and/or the maximum price (or a formatted price range):

$product = wc_get_product( get_the_id());

if( is_a( $product, 'WC_Product' ) || ! empty( $product ) ) {
    
    // 1. Variable product (min and max)
    if ( $product->is_type('variable') ){
        $price_min = $product->get_variation_price('min'); // Float number
        $price_max = $product->get_variation_price('max'); // Float number

        $formatted_price_range = $product->get_price_html(); // Html formatted price range
    }

    // 2. Single product
    elseif ( $product->is_type('simple') ){
        $price = $product->get_price(); // Float number

        $formatted_price = $product->get_price_html(); // Html formatted price range
    }
}

It should better work now.
