A company can use material that it already owns, bought for £6 per kg, in a special order. It has no other use for it except selling it as scrap at £2 per kg. The replacement cost is £9 per kg. What is the relevant cost per kg of using the material?

Answer and explanation

Correct answer: A. £2

  1. Step 1: When material is already owned and not needed elsewhere, the relevant cost is the better of its resale value and the cost of reusing it.
  2. Step 2: Here the only alternative use is sale as scrap at £2 per kg, so using it loses £2.
  3. Step 3: Historic cost is sunk.
Answer
£2.
Why not the others: £6: This is the historic cost, which is a sunk cost and not relevant. £9: The replacement cost is relevant only if the material would be replaced; here it will not be. £4: This is the difference between the cost and the scrap value, which has no use in the decision.
