Let us assume that standard direct material cost of widget is as follows: 2 kg of unobtainium at € 60 per kg ( = € 120 per unit). Let us assume further that during given period, 100 widgets were manufactured, using 212 kg of unobtainium which cost € 13,144. Under those assumptions direct material usage variance can be calculated as:
