Replacement Cost Method--By Product Costing:
Learning Objectives:
- Define and explain replacement cost
method.
- What is the use of replacement cost
method while cost by-products?
Replacement cost method ordinarily is applied by
firms whose by-products are used within the plant, thereby avoiding the
necessity of purchasing materials and supplies from outside suppliers. The
production cost of the main product is credited for such materials, and the
offsetting debit is to the department that uses the by product. The cost
assigned to the by product is the purchase or replacement cost existing in
the market. This method is common in the steel industry. Although many
by-products are sold in the open market, other products, such as blast
furnace gas and coke oven gas, are mixed and used for heating in open hearth
furnaces. The waste heat from open hearths is used again in the generation
of steam needed by the various producing departments. The resourceful use of
these by-products and their accounting treatment are indicated by the
following procedure used by a steel company:
- Coke oven by-products are credited to the
cost of coke at the average sales price per unit for the month.
- Coke oven and blast furnace gas are
credited respectively to the cost of coke and the cost of big iron at a
computed value based on the cost of fuel oil yielding equivalent heat
units.
- Tar and pitch used as fuel are credited
respectively to the cost of coke at a computed value based on the cost of
fuel oil yielding equivalent heat units.
- Scrape steel remelted is credited to the
cost of finished steel at market cost of equivalent grades purchased.
- Waste heat from furnaces used to generate
steam is credited to the steel ingot cost at a computed value based on the
cost of coal yielding equivalent heat units.
