Learning Objectives 5.Compute the labor variances and explain how they are used for control. 6.(Appendix 9A) Prepare journal entries for materials and labor variances. 7.(Appendix 9B) Define kaizen and target costing and explain their relationship to traditional standard costing.

What three ways are used to develop standards?

Define Ideal and Currently Attainable Standards ◙ Ideal Standards Demands maximum efficiency and is achievable only when everything operates perfectly. There are no breakdowns, slack, or skill failures. ◙ Currently Attainable Standards Are achievable under efficient operating conditions, but allowances are made for breakdowns, interruptions, some mistakes and so on.

Illustrate Types of Standards

Why have a standard cost system? ◙ It enhances planning and control and improves performance measurement ◙ Allows comparison of actual and budget and analysis of variances (differences) ◙ Broken down into price and efficiency variances ◙ Managers over inputs than prices ◙ Standard cost systems are widely used

How to compute standard quantities allowed (SQ & SH) Assume that 200,000 packages of corn chips are produced during first week of April. The unit quantity standard is 18 ounces of yellow corn per package. The unit quantity standard for machine operators is 0.01 DLH per package produced. REQUIRED: How much yellow corn and how many operator hours should have been used or the actual output of 200,000 packages? Calculation: Corn allowed SQ = Unit quantity standard x Actual output = 18 oz. x 200,000 = 3,600,000 oz. Operator hours allowed SH = Unit labor standard x Actual output = 0.01 DLH x 200,000 = 2,000 DLH 9-1

Brief Describe the Total Budget Variance, Price & Efficiency Variance ◙ The actual cost – The planned cost = (AP x AQ) – (SP x SQ) It is also call the TOTAL VARIANCE ◙ The Price or Rate variance is the (Actual price – Standard Price) x Actual number of units used =(AP – SP) x AQ ◙ The Usage or Efficiency variance is the (Actual Quantity – Standard Quantity) x Standard Price = (AQ – SQ) x SP

Draw the General Variance Model Total Variance (1 – 3) Total Variance (1 – 3) 1.AQ X AP (Actual Quantity Of input at Actual Price) 1.AQ X AP (Actual Quantity Of input at Actual Price) 3. SQ X SP (Standard Quantity Of input at Standard Price) 3. SQ X SP (Standard Quantity Of input at Standard Price) 2. AQ X SP (Actual Quantity Of input at Standard Price) 2. AQ X SP (Actual Quantity Of input at Standard Price) Price Variance (1 - 2) Price Variance (1 - 2) Usage Variance (2 – 3) Usage Variance (2 – 3)

How to use control limits to trigger a variance investigation Information: Standard costs: \$100,000; allowable deviation +10,000; actual costs for six months: June\$97,500September \$102,500 July105,000October 107,500 August 95,000November 112,500 Required: Plot the actual costs over time against the upper and lower control lines. Determine when a variance should be investigated. Calculation: Appears on the following two slides. 9-2
