    Standard Costs

    Standards are benchmarks or norms formeasuring performance. In managerial accounting,

    two types of standards are commonly used.

    Quantity standardsspecify how much of aninput should be used to

    make a product or

    provide a service.

    Price standardsspecify how muchshould be paid for

    each unit of the

    input.

    Examples: Firestone, Sears, McDonalds, hospitals,

    construction and manufacturing companies.

    Accountants, engineers, purchasingagents, and production managers

    combine efforts to set standards that encourage

    efficient future operations.

    Setting Standard Costs

    Should we useideal standardsthatrequire employees towork at 100 percent

    peak efficiency?

    Engineer Managerial Accountant

    I recommend using practicalstandardsthat are currentlyattainable with reasonable

    and efficient effort.

    Learning Objective 1

    Explain how directmaterials standards and

    direct laborstandards are set.

    Setting Standards

    Six Sigma advocates have sought toeliminate all defects and waste, rather than

    continually build them into standards.

    As a result allowances for waste andspoilage that are built into standards

    should be reduced over time.

  • 8/11/2019 chap011 StandardCosting (1)

    10/109

    Setting Direct Labor Standards

    RateStandards

    Often a singlerate is used that reflectsthe mix of wages earned.

    TimeStandards

    Use time andmotion studies for

    each labor operation.

    Setting Variable Manufacturing OverheadStandards

    RateStandards

    The rate is thevariable portion of the

    predetermined overhead

    rate.

    QuantityStandards

    The quantity isthe activity in the

    allocation base for

    predetermined overhead.

    A standard cost card for one unit ofproduct might look like this:

    Direct materials 3.0 lbs. 4.00$ per lb. 12.00$

    Price and Quantity Standards

    Price and quantity standards aredetermined separately for two reasons:

    The purchasing manager is responsible for rawmaterial purchase prices and the production manageris responsible for the quantity of raw material used.

    The buying and using activities occur at different times.Raw material purchases may be held in inventory for aperiod of time before being used in production.

    Isolation of Material Variances

    I need the price variancesooner so that I can betteridentify purchasing problems.

    You accountants just dontunderstand the problems that

    purchasing managershave.

    Ill start computingthe price variancewhen material is

    purchased ratherthan when its used.

    How are the variancescomputed if the amountpurchaseddiffers from

    The price variance iscomputed on the entire

    The quantity varianceis computed only on

    Hanson Inc. has the following variablemanufacturing overhead standard to

    manufacture one Zippy:

    1.5 standard hours per Zippy at$3.00 per direct labor hour

    Last week, 1,550 hours were worked to make

    1,000 Zippies, and $5,115 was spent forvariable manufacturing overhead.

    Inventories are recorded at standard cost.

    Variances are recorded as follows:

    Favorable variances are credits, representingsavings in production costs.

    Unfavorable variances are debits, representingexcess production costs.

    Standard cost variances are usually closed out

    to cost of goods sold. Unfavorable variances increase cost of goods sold.

    Favorable variances decrease cost of goods sold.
