Simple Usage:

Filter: woocommerce_cart_calculate_fees

function woocommerce_cart_custom_fee() {
    if(WC()->cart->total < 25){ //Check for cart total is < 25
        $custom_fee = WC()->cart->total + 5; // Here $5 will add as custom fee
    } else {
        $custom_fee = WC()->cart->total; //If cart total is > 25 it will not add custom fee
    }
    $handling_cost = $custom_fee / 2; //Adding Handling Cost
    $fee = $custom_fee + $handling_cost; // Custom Fee + Handling Cost
    WC()->cart->add_fee('Transport Fee:', $fee); //It will add fee
}
