The computation of Static Budget Variance is shown below:-
Static Budget Variance = Direct-material quantity variance + Direct-material quantity variance + Labor efficiency variance + Labor rate variance
= $10,800 F - $2,500 U - $3,000 U - $1,400 U
= $3,900 Favorable
If the overall quality of the product has not suffered, the variance number is best used to determine the appropriateness of the purchasing manager's decision to purchase substandard material is $3,900 Favorable.
