When analising the effects of deliberately buying better material, we compare material expenditure variance with material volume + labour efficiency + variable OH efficiency variances. But we don’t take into consideration the fixed OH volume variance. What is the logic behind, please?
sorry, we also consider the sales volume and sales price variance. Additional question: when we conclude whether it was a good move to buy better material do we add up all these fav and adv variances? ($3,867) vs 612+2,000+800+2,800+(16,800)+perhaps 3,000 fixed OH vol var?
I have been watching through all of the PM lectures so far and cannot thank you enough! Your lectures are excellent and just as I think I have a question you answer it in the same lecture.
On your point about deliberately buying higher priced materials to increase selling price or sales volume, can I check why it is that Sales Volume variances are based on contribution/profit per unit instead of selling price per unit?
Because although selling more means there is more revenue, it also means there are more costs of the goods. Therefore selling more units means more contribution.

Hi John,
Thank you very much for the clear lectures!
