Dear John,
I hope this email find you well.
I have a question related to Relevant Costing. The question is as below:
“A company needs 5,000 hours of labour for a contract they have been asked to quote for. The work currently being carried out by our employees is generating a contribution of $12 per hour, and using them on the contract will mean taking them away from their other work, our workers are paid at the rate of $8 per hour.”
A. $60,000
B. $NIL
C. $40,000
D. $100,000The answer was D $100,000, and the calculation was $12 + $8 x 5000hrs
May I ask why the $8 of wages was consider as relevant cost to the contract? As for my understanding, even those we do not receive this new contract, we still have to pay $8 per hour to the workers. But unfortunately, my assumption was wrong. Please, may I seek for your guidance on this?
Thank you,

Here is a short example to explain:
Suppose they are currently making a product that has a selling price of $20 per units, a material cost of $5 per unit, and a labour cost of $7 per unit. So the contribution is $8 per unit. Also, each unit takes 1 hour to make.
If we take away 1 hour for a new product, then we lose the $20 revenue. We save the material cost of $5. But we still still be paying the labour of $7.
Therefore the net cost of taking 1 hour is 20 – 5 = $15. This is the same (and is always the same) as the contribution plus the labour cost ($8 + $7 = $15).

I know better now.May 18, 2021 at 8:52 am #620922🙂
