Which one better?

Normal product costing and standard
costing are preferable
5
Reasons

Under actual costing, the product cost will be
delayed until the end of the accounting
period. However, the product cost should be
obtained beforehand for setting selling price
 Since monthly productivity may vary due to
holiday periods and seasonal variation, actual
overhead is fluctuating and cannot reflect
normal production conditions
