Review Materials – Management Services Standard Costing Standard Costing is a budgeting control technique with 3 components: (1) a standard, predetermined performance level; (2) a measure of actual performance; and (3) a measure of the variance, the difference, between the standard and the actual. This is generally best suited to organizations with repetitive activities. It is probably most relevant to manufacturing organizations with repetitive production processes. Standard costing cannot be applied easily to non-repetitive activities because there is no clear basis for observing and recording operations. It is difficult to determine a clear standard. Standard Costing may be defined basically as a technique of cost accounting which compares the “standard cost” of each product or service with the actual cost, to determine the efficiency of the operation, so that any remedial action may be taken immediately. A standard cost is a predetermined cost of manufacturing, servicing, or marketing an item during a given future period. It is based on current and projected future conditions. The norm is also dependent on quantitative and qualitative measurements. Standards may be based on engineering studies looking at time and motion. The formulated standard must be accurate and useful for control purposes. Standards are set at the beginning of the period. They may be in physical and peso terms. Standards assist in the measurement of both effectiveness and efficiency. Examples: sales quotas, standard costs (e.g., material price, wage rate), and standard volume. Variances are not independent, so a favorable variance in one responsibility area may result in an unfavorable one in other segments of the business. “Variance” is the difference between a budgeted or standard amount and the actual amount during a given period. Variance Analysis is defined to be an analysis of the cost variances into its component parts and the explanation of the same. It is that part of the process of control which involves the calculation of a variance and interpretation of results for identifying the causes thereof and also for pinpointing responsibility. Variances are normally calculated for all the cost components such as Materials, Labor and Overheads. Variances are also calculated for Revenues, i.e., Sales and also for Net profits (Sales - Costs). Variance analysis compares standard to actual performance. It could be done by division, department, program, product, territory, or any other responsibility unit. When more than one department is used in a production process, individual standards should be developed for each department in order to assign accountability to department managers. Variances may be as detailed as necessary, considering the cost/benefit relationship. Evaluation of variances may be done yearly, quarterly, monthly, daily, or hourly, depending on the importance of identifying a problem quickly. Because actual figures (e.g., hours spent) are not known until the end of the period, variances can be determined only at this time. A material variance requires notifying the person responsible and taking corrective action. Insignificant variances need not be looked into further unless they recur repeatedly and/or reflect potential difficulty. Generally, a variance should be investigated when the inquiry is anticipated to result in corrective action that will reduce costs by an amount exceeding the cost of the inquiry.

Aid in inventory costing Assist in decision making Sell price formulation based on what costs should be Aid in coordinating by having all departments focus on common goals Set and evaluate divisional objectives Allow cost control and performance evaluation by comparing actual to budgeted figures. The objective of cost control is to produce an item at the lowest possible cost according to predetermined quality standards. Highlight problem areas through the “management by exception” principle Pinpoint responsibility for undesirable performance so that corrective action may be taken. Variances in product activity (cost, quality, quantity) are typically the production manager’s responsibility. Variances in sales orders and market share are often the responsibility of the marketing manager. Variances in prices and methods of deliveries are the responsibility of purchasing personnel. Variances in profit usually relate to overall operations. Variances in return on investment relate to asset utilization. Motivate employees to accomplish predetermined goals Facilitate communication within the organization, such as between top management and supervisors Assist in planning by forecasting needs (e.g., cash requirements) Establish bid prices on contracts

STANDARD SETTING Standards may be set by engineers, production managers, purchasing managers, and personnel administrators. Depending on the nature of the cost item, computerized models can be used to corroborate what the standard costs should be. Standards may be established through test runs or mathematical and technological analysis. Standards are based on the particular situation being appraised. Capacity may be expressed in units, weight, size, peso, selling price, and direct labor hours. It may be expressed in different time periods (e.g., weekly, monthly, yearly).

TYPES OF STANDARDS 1. Basic. These are not changed from period to period and are used in the same way as an index number. They form the basis to which later period performance is compared. What is unrealistic about basic standards is that no consideration is given to a change in the environment. 2. Maximum efficiency. These are perfect standards assuming ideal, optimal conditions, allowing for no losses of any kind, even those considered unavoidable. They will always result in unfavorable variances. Realistically, certain inefficiencies will occur, such as materials will not always arrive at workstations on time and tools will break. Ideal standards cannot be used in forecasting and planning because they do not provide for normal inefficiencies. 3. Currently attainable (practical).These refer to the volume of output possible if a facility operated continuously, but after allowing for normal and unavoidable losses such as vacations, holidays, and repairs. Currently attainable standards are based on efficient activity. They are possible but difficult to achieve. Considered are normal occurrences such as anticipated machinery failure and normal materials shortage. Practical standards should be set high enough to motivate employees and low enough to permit normal interruptions. Besides pointing to abnormal deviations in costs, practical standards may be used in forecasting cash flows and in planning inventory. Attainable standards typically are used in practice. 4. Expected. These are expected figures based on foreseeable operating conditions and costs. They come very close to actual figures.

Standards should be set at a realistic level. Those affected by the standards should participate in formalizing them so there will be internalization of goals. When reasonable standards exist, employees typically become cost conscious and try to accomplish the best results at the least cost. Standards that are too tight will discourage employee performance. Standards that are too loose will result in inefficient operations. If employees receive bonuses for exceeding normal standards, the standards may be even more effective as motivation tools. A standard is not an absolute and precise figure. Realistically, a standard constitutes a range of possible acceptable results. Thus, variances can and do occur within a normal upper-lower limit. In determining tolerance limits, relative magnitudes are more important than absolute values. For instance, if the standard cost for an activity is P 100,000, a plus or minus range of P 4,000 may be tolerable.

Direct Materials Standards and Variance Analysis: Standard price per unit of direct materials is the price that should be paid for a single unit of materials, including allowances for quality, quantity purchased, shipping, receiving, and other such costs, net of any discounts allowed. I. Direct Materials Price Variance: Direct materials price variance is the difference between the actual purchase price and standard purchase price of materials. Direct materials price variance is calculated either at the time of purchase of direct materials or at the time when the direct materials are used. II. Direct Materials Quantity Variance: Direct materials quantity variance or Direct materials usage variance measures the difference between the quantity of materials used in production and the quantity that should have been used according to the standard that has been set. Although the variance is concerned with the physical usage of materials, it is generally stated in dollar terms to help gauge its importance. III. Direct Materials mix and Yield Variance: Basically, the establishment of standard product cost requires the determination of price and quantity standards. In many industries, particularly of the process type, materials mix and materials yield play significant parts in the final product cost, in cost reduction, and in profit improvement. Materials mix variance formula (Actual quantities at individual standard materials costs) – (Actual quantities at weighted average of standard materials costs) Materials yield variance formula (Actual quantities at weighted average of standard materials costs) – (Actual output quantity at standard materials cost)

Direct Labor Standards and Variance Analysis: Direct labor price and quantity standards are usually expressed in terms of a labor rate and labor hours. The standard rate per hour for direct labor includes not only wages earned but also fringe benefit and other labor costs. I. Direct Labor Rate | Price Variance: Direct Labor price variance is also termed as direct labor rate variance. This variance measures any deviation from standard in the average hourly rate paid to direct labor workers. II. Direct Labor Efficiency | Usage | Quantity Variance: The quantity variance for direct labor is generally called direct labor efficiency variance or direct labor usage variance. III. Direct labor yield variance formula: (Standard hours allowed for expected output × Standard labor rate) – (Standard hours allowed for actual output × Standard labor rate)

Manufacturing Overhead Standards and Variance Analysis: Procedures for the establishing and using standard factory overhead rates are similar to the methods of dealing with the estimated direct and indirect factory overhead and its application to jobs and products. Jobs or processes are charged with cost on the basis of standard hours allowed multiplied by the standard factory over head rate. The standard overhead rate or predetermined overhead rate is discussed in detail at our job order costing system page. The standard hours allowed figure is determined by multiplying the labor hours required to produce one unit (the standard labor hours per unit) times the actual number of units produced during the period. The units produced are the equivalent units of production for the departmental factory overhead cost being analyzed. At the end of the month, overhead actually incurred is compared with the expenses charged into process using the standard factory overhead rate. The difference between these figures is called the overall or net factory overhead variance. Overall or net factory overhead variance needs further analysis to reveal detailed causes for the variance and to guide management toward remedial action. This analysis may be made by using (1) the two variance method, (2) the three variance method, or (3) the four variance method. The two variance method: When an overall or net factory overhead variance is further analyzed by using two variance approach, the following two variances are calculated: (1) Controllable variance; and (2) Volume variance. Factory overhead controllable variance formula: (Actual factory overhead) – (Budgeted allowance based on standard hours allowed*) Factory overhead volume variance: (Budgeted allowance based on standard hours allowed*) – (Factory overhead applied or charged to production**) The three variance method: When an overall or net factory overhead variance is further analyzed by using three variance approach, the following three variances are calculated: (1) Spending variance; (2) Idle capacity variance; and (3) Efficiency variance. Factory overhead spending variance: (Actual factory overhead) – (Budgeted allowance based on actual hours worked***) Factory overhead idle capacity variance formula: (Budgeted allowance based on actual hours worked***) – (Actual hours worked × Standard overhead rate) Factory overhead efficiency variance formula: (Actual hours worked × Standard overhead rate) – (Standard hours allowed for expected output × Standard overhead rate) The four variance method: When an overall or net factory overhead variance is further analyzed by using four variance approach, the following four variances are calculated: (1) Spending variance; (2) Variable efficiency variance; (3) Fixed efficiency variance; and (4) Idle capacity variance. Factory overhead spending variance: (Actual factory overhead) – (Budgeted allowance based on actual hours worked***) Factory overhead idle capacity variance formula: (Budgeted allowance based on actual hours worked***) – (Actual hours worked × Standard overhead rate) Variable overhead efficiency variance formula: (Actual hours worked × Standard variable overhead rate) – (Standard hours allowed × Standard variable overhead rate) Fixed overhead efficiency variance formula: (Actual hours worked × Fixed overhead rate) – (Standard hours allowed × Fixed overhead rate) * Fixed overhead budgeted + Standard hours allowed × Standard variable overhead rate ** Standard hours allowed for actual production × Standard overhead rate ***Fixed overhead budgeted + Actual hours worked × Standard variable overhead rate Page | 4

VARIANCE ANALYSIS ILLUSTRATION To illustrate how cost variance analysis works, assume you are the plant manager for Bases, Inc., a company that makes a set of soft bases for playing baseball in gymnasiums. The budget assumes 150,000 sets of bases will be produced annually. The following standard cost per set of bases was developed: Quantity per set Cost Cost per set Direct materials 4.5 feet $1.10 $4.95 Direct Labor .5 hour $9 per hour 4.50 Manufacturing Overhead .5 hour $1.30 per hour .65 Total Cost per Unit $10.10

The predetermined overhead rate of $1.30 will result in $0.65 of overhead being allocated to each set of bases produced. (It is calculated using .5 direct labor hours per set times $1.30 per hour.) Bases, Inc. Manufacturing Overhead Budget 20X1 Production in Units 150,000 Direct Labor Hours per Unit = .5 Direct Labor Hours = 75,000 *** Cost per Direct Labor Hour Total Cost Monthly Cost Variable Costs Indirect Materials $0.02 $ 1,500 * Indirect Labor .40 30,000 * Maintenance .30 22,500 * Total Variable Costs $0.72 54,000 * Fixed Cost Depreciation, Machinery 6,300 $525 ** Building Rent 12,000 1,000 ** Supervisor's Salary 25,200 2,100 ** Total Fixed Costs 0.58 43,500 $ 3,625 ** Total Manufacturing Overhead (1) $1.30 $97,500 Budgeted Direct Labor Hours (2) 75,000 Predetermined (standard) Overhead Rate (1) ÷ (2) $1.30 The overhead costs per direct labor hour are: Variable Costs ($54,000/75,000 hours) Fixed Costs ($43,500/75,000 hours) Total Overhead Cost per Direct Labor Hour

For the month of October, the company produced 13,300 sets of bases. The following information was taken from the October financial report.

Unfavorable Variance

$ 1,175

In order to understand the $1,175 unfavorable monthly variance, it must be analyzed by its component parts: direct materials variances, direct labor variances, and overhead variances. Each of these variances can further be broken down into a price (rate) variance and a quantity (usage or efficiency) variance. A general template that can be used for direct materials variances, direct labor variances, and variable overhead variances uses three amounts — actual, flexible budget, and standard — as a basis for calculating the variances.

The price variance is favorable if actual costs are less than flexible budget costs. The quantity variance is favorable if flexible budget costs are less than standard costs. The total variance is favorable if the actual costs are less than standard costs.

Direct Materials Variances The total direct materials variance is $2,835 favorable and consists of a $3,000 favorable price variance and a $165 unfavorable quantity variance.

Actual costs of $63,000 are less than flexible budget costs of $66,000, so the materials price variance is $3,000 favorable. The variance can also be thought of on a price per unit basis. The actual costs of $63,000 were for 60,000 feet of direct material, so the actual price per foot is $1.05 ($63,000 ÷ 60,000). The original budget was for a direct materials cost of $1.10 per foot, so it was expected that 60,000 feet of material would cost $66,000. The direct materials actually cost less than budget by $0.05 per foot ($1.10 budget versus $1.05 actual), so the variance is favorable. The direct materials quantity variance of $165 unfavorable means this company used more direct materials than planned because flexible budget costs of $66,000 are higher than the standard costs of $65,825. To produce 13,300 sets of bases, the company expected a cost of $4.95 per set (4.5 feet of material at $1.10 per foot), for a total cost of $65,835. This can also be analyzed by identifying the total feet of material it should have taken to produce 13,300 sets of bases and multiplying by the cost per foot of material (13,300 sets × 4.5 feet per unit = 59,850 feet of direct materials × $1.10 per foot = $65,835). It actually used 60,000 feet, which prices out at an expected $1.10 per foot to be $66,000. The total direct materials variance is calculated by adding the price and quantity variances together or by comparing actual cost of direct materials with the standard cost of producing 13,300 sets of bases. Page | 6

Another way of computing the direct materials variance is using formulas.

Using the formulas to calculate the variances would work like this: Direct materials price variance: $3,000 F = [(60,000 × $1.05) – (60,000 × $1.10)]

or

60,000($1.05 - 1.10)

$3,000F = $63,000 - $66,000

or

60,000 × $0.05

Direct materials quantity variance: $165 U = [(60,000 × $1.10) - ((13,300 × 4.5) × $1.10)] or

$1.10(60,000 - (13,300 × 4.5))

($165 U = ($66,000 - (59,850 × $1.10))

or

$1.10(60,000 - 59,850)

$165 U = $66,000 - 65,835

or

$1.10 × 150

Once the variances are calculated, management completes the analysis by obtaining explanations for why the variances occurred. For example, a question raised is “Why did materials cost less than planned?” As an answer, management may learn there was a price decrease, or the direct materials were acquired from another source, or lower quality materials were obtained. The explanations for price variances must relate to the cost of the direct materials, not the quantity of the materials used. Similarly, the reasons for the quantity variance need to relate to the amount of materials used, not the price paid for the materials. Reasons for a quantity variance could be more waste or scrap than was planned, or that lower quality materials were used, or less skilled workers were hired or used on the production line, or machine problems occurred that damaged materials.

Direct Labor Variances The total direct labor variance is $3,525 unfavorable and consists of a $4,875 unfavorable rate variance and a $1,350 favorable efficiency variance. Actual labor costs of $63,375 are more than flexible budget costs of $58,500, so the labor rate variance is $4,875 unfavorable. As with materials, the labor can also be thought of on a price per hour basis. The actual costs of $63,375 were for 6,580 hours, which calculates to an average pay rate of $9.75 per direct labor hour. The budget used a rate of $9.00 per direct labor hour. This $0.75 per hour difference resulted in the unfavorable rate variance because actual costs were higher than budgeted costs. This could result from unplanned but negotiated wage rate increases or the use of a more skilled work force.

The efficiency variance is favorable because flexible costs of $58,500 are less than standard costs of $59,850. This means that the employees took less time than budgeted to produce the 13,300 sets of bases. 13,300 units were produced, and the company expected that the labor cost would be $4.50 per set, for a total labor cost of $59,850. This can also be analyzed by identifying the total hours of labor it should have taken to produce 13,300 sets of bases and multiplying by the cost per hour of labor (13,300 sets × .5 hours = 6,650 hours × $9 per hour = $59,850). Because only 6,500 direct labor hours were needed instead of the 6,650 hours expected, the direct labor efficiency variance is favorable.

Overhead Variances Variances may occur for both the variable and fixed cost components of manufacturing overhead. Before looking at the variances, a summary of the overhead information for Bases, Inc., might be helpful.

The variances can be calculated in total for variable and fixed costs, in which case the variances are referred to as the controllable (price) variance and the volume variance. Alternatively, the variances can be calculated separately for variable manufacturing overhead costs and fixed manufacturing overhead costs. The variable overhead cost variances are called the spending (rate) variance and the efficiency variance, and fixed overhead cost variances are known as the spending and volume variances. The variable overhead cost spending variance, the variable overhead cost efficiency variance, and the fixed overhead cost spending variance added together are the same as the controllable variance.

Using the two-variance approach, the controllable cost variance shows how well management controls its overhead costs. If a volume variance exists, it means the plant operated at a different production level than budgeted. For the Bases, Inc., the total overhead variance is $485 unfavorable. It consists of a $717 unfavorable controllable variance and a $232 favorable volume variance. An unfavorable controllable variance indicates that overhead costs per direct labor hour were higher than expected. The variance is calculated by subtracting the $8,413 budgeted overhead from the $9,130 actual overhead costs. The budgeted overhead is calculated by adding budgeted variable costs for the actual number of units (think of this as the flexible budget amount) to the budgeted fixed costs (unchanged from original budget). For Bases, Inc., production was 13,300 units and variable costs were $0.72 per direct labor hour. As each unit takes .5 direct labor hours to make, the variable overhead is 13,300 units times .5 hours times $0.72, or $4,788. When added to fixed costs of $3,625, the total budgeted overhead costs are $8,413 for the month. Possible reasons for the unfavorable variance are: indirect materials were purchased from a different supplier with higher costs, or more indirect materials were used due to waste; indirect labor rates were higher due to a change in personnel or higher negotiated raises than budgeted; and/or fixed overhead costs were more than budgeted. The $232 volume variance indicates an over-application of fixed costs. This occurred because actual production is higher than the budget. Remember that as more units are produced, fixed costs per unit decrease. However, the predetermined overhead rate is established when the budget is prepared, and the same rate is used throughout the year regardless of the actual number of units produced. So even though the fixed costs per unit

Page | 10

decreased when 13,300 units were produced rather than the 12,500 budgeted, the same predetermined overhead rate using the higher cost per unit was used to allocate overhead to production.

Using the separate overhead variance calculations for variable and fixed costs, the total overhead variance is the same $485 unfavorable. The total variable overhead cost variance is $542 unfavorable, indicating actual variable costs were higher than standard variable costs and, therefore, the overhead is underapplied. The total fixed overhead variance is $57 favorable, indicating overhead is overapplied, because the actual fixed costs are less than the standard fixed costs. The $650 unfavorable variable cost spending variance is calculated by subtracting the $4,680 flexible budget for variable overhead (actual direct labor hours times variable overhead per direct labor hour, or 6,500 × $0.72) from the actual variable overhead of $5,330. It is unfavorable because more was spent on variable overhead costs per direct labor hour than the $0.72 that was budgeted. Knowing that total variable costs are $5,330 and that 6,500 direct labor hours were incurred, the actual variable overhead costs per direct labor hour rate was $0.82. The $108 favorable efficiency variance is determined by subtracting $4,788 standard overhead (13,300 units by the variable overhead per unit predetermined rate of $0.36) from the flexible budget variable overhead cost of $4,680. It occurred because it took only 6,500 direct labor hours instead of 6,650 (13,300 units × .5 hours per unit) direct labor hours to produce the 13,300 units. The total variable cost variance of $542 is calculated by adding the $650 unfavorable spending variance and the $108 favorable efficiency variance.

The $175 unfavorable fixed cost spending variance indicates more was spent on fixed costs than was budgeted. It is calculated by subtracting the budgeted fixed overhead per month of $3,625 from the $3,800 actual fixed overhead. The $232 favorable volume variance indicates fixed overhead costs are overapplied. This occurred because there were more units produced than planned. It is calculated by subtracting the applied fixed overhead based on standard cost for units produced of $3,857 (13,300 sets × $0.29 per unit) from budgeted fixed

Page | 11

overhead of $3,625. The total fixed overhead cost variance of $57 favorable is the combination of the $175 unfavorable spending variance and the $232 favorable volume variance.

When combined together, the variable overhead spending variance, the variable overhead efficiency variance, and the fixed cost spending variance equal the $717 unfavorable controllable variance calculated under the two-variance method previously discussed.
