If the standard price is reasonable, then a materials price variance may be caused
by such valid factors as the following:

 Market-driven pricing changes, such as changes in the prices of commodities
 Bargaining power changes by suppliers, who may be able to impose higher
prices than expected
 Buying in unusually large or small volumes in comparison to what was expected
when the standard was created
 A change in the quality of the materials purchased
ii) The possible causes of labor rate variance are:
 Payment at a higher or lower rate than the standard
 Changes in employee skills
 Recruitment of new personnel
 Changes in compensation methods, etc.
