Variance Analysis Topic Three
Why Standard Cost Systems Are Adopted • Standard costing systems enhance planning and control and improve performance measurement. • Standard costing systems facilitate product costing.
Ideal Standards demand maximum efficiency and can be achieved only if everything operates perfectly. Currently attainable standards can be achieved under efficient operating conditions. Kaizen standards reflect a planned improvement and are a type of currently attainable standard. Developing Unit Input Standards 9-3

During the first week of March, 100,000 packages of corn chips are produced. The standard quantity of yellow corn meal per package is 18 ounces.
Standard Quantity of Materials Allowed SQ = Unit quantity standard x Actual output = 18 x 100,000 = 1,800,000 ounces Standard Hours Allowed SH = Unit labor standard x Actual output = 0.0008 x 100,000 = 80 direct labor hours Total variance = Price variance +Usage variance = (AP x AQ) – (SP x SQ)

Unfavorable (U)variances occur whenever actual prices or usage of inputs are greater than standard prices or usage. Favorable (F) variance occurs whenever actual prices or usage of inputs are less than standard prices or usage

Variance Analysis and Accounting: Investigating Variances: Because random variations around the standard are expected, management should establish an acceptable range of performance. The acceptable range is the standard, plus or minus one allowable deviation. The upper control limit is the standard plus the allowable deviation and the lower control limit is the standard minus the allowable deviation. 1-13

Material Price Variance MPV = (AP – SP)AQ The actual price per unit The standard price per unit The actual quantity of material used
Material Price Variance MPV = (AP – SP)AQ = ($0.0069 – $0.0060)780,000 = $0.0009 x 780,000 = $702 U
Direct Materials Usage Variance MUV = (AQ – SQ)SP The actual quantity of materials used The standard quantity of materials allowed for the actual output The standard price per unit
Direct Materials Usage Variance MUV = (AQ – SQ)SP = (780,000 – 873,000)($0.006) = 93,000 x $0.006 = $558 F
Labor Rate Variances LRV = (AR – SR)AH The actual hourly wage rate The standard hourly wage rate The actual direct labor hours used

Direct Labor Yield Variance • Using the standard mix information and the actual results, the yield variance is computed as follows: • Yield variance = (Standard yield – Actual yield)SP • = [(24 x 50) – 1,300]$0.45 • = (1,200 – 1,300)$0.45 • = $45 F • The yield variance is favorable because the actual yield is greater than the standard yield. y
