What are the two components of the direct materials variance?

Intermediate

Answer

The total direct materials variance splits into the materials price variance—(standard price - actual price) x actual quantity purchased/used—and the materials usage (quantity) variance—(standard quantity for actual output - actual quantity) x standard price. Price reflects buying, usage reflects consumption efficiency.
Price = (SP - AP) x AQ.  Usage = (SQ - AQ) x SP.
Real-world example Buying cheaper material gives a favorable price variance; wasting material gives an adverse usage variance.
