Materials Usage Variance
Accounting glossary · Understand, connect, apply
The materials usage variance measures the cost effect of using a different quantity of material from the standard quantity allowed for actual output, valued at the standard material price.
Example
Actual output should use 500 kilograms, but 530 kilograms are consumed. At a standard price of 4 per kilogram, the usage variance is 30 × 4 = 120 unfavourable.
Formula and assumptions
Usage variance = (actual quantity used − standard quantity allowed) × standard price; positive means unfavourable
Remember the difference
Use the standard quantity for actual output, not the original planned output. Investigate waste, specification, quality and recording before attributing the difference to production performance.
