Classify each cost as being either variable or fixed with re
Solution
For understanding the concept of variable and fixed, we need to put a simple question. Does the cost increase if production is increased. If the answer is YES ---- it is variable and If the answer is NO --- it is Fixed. In the above question we see (1) hamburgers buns, (3) apples (4) shipping cost, (8) sales commissons and (10) steering wheels are all having the behavior of increase or decrease for variation in production and sale. So they are called variable costs.
For understanding the concept of period cost and product cost, we have understand that all costs like direct material, direct labour and all factory overheads are product costs. All other overheads like administrative and selling and distribution shall be period costs. Thus it is easy to remember that what is not a product cost is the period cost. Item (5) and Item (6) above gives a clear understanding. Insurance on factory is product cost but Insurance on corporate office is period cost.
