In PHP, what are the advantages and drawbacks of pre-calculating values like fees before sending them to the client-side for display and manipulation?

When pre-calculating values like fees in PHP before sending them to the client-side, the main advantage is that it reduces the processing load on the client-side, leading to faster loading times and improved user experience. However, the drawback is that it may increase server load, especially if the calculations are complex and need to be done frequently. It's important to strike a balance between pre-calculating values and offloading some calculations to the client-side when feasible. 

// Pre-calculate fees before sending to client-side
$basePrice = 100;
$feePercentage = 0.1;
$feeAmount = $basePrice * $feePercentage;
$totalPrice = $basePrice + $feeAmount;

// Send pre-calculated values to client-side
echo json_encode([
    'basePrice' => $basePrice,
    'feeAmount' => $feeAmount,
    'totalPrice' => $totalPrice
]);
