# Calculating costs from price/kg and % of client's purchases

Case Calculations

Hello,

Can you please tell me, what formula/koncept is used to get cost of material when I know the price/kg and % of the client's material purchases? I can see from the case that the price/kg is multiplied by the percentage, so for example \$80/kg*40%=\$32 but I wouldn't be able to come with this step. Could you please advise what the idea behind it is so I would be able to use it next time?

Thank you

Hi,

Your question is completely unclear. If the cost is the % of the price, then you simply multiply the two numbers

Hi

Your question isn't absolutely clear. If you share the question verbatim, I might be of more assitance.

To confirm: you were asked to calculate Cost of raw material. You were given Price/Kg and % of the price that is material purchase.

To me it then seems fairly obvious that the CoM would be the % mulitplied by the price/kg.
