Standard Costs Standards are benchmarks or “norms”for measuring performance. Two typesof standards are commonly used. Quantity standardsspecify how much of aninput should be used tomake a product orprovide a service. Cost (price)standards specify how much should be paid for each unitof the input.
Deviations from standard deemed significantare brought to the attention of management, apractice known as management by exception. Standard Costs Standard Amount DirectMaterial DirectLabour ManufacturingOverhead Type of Product Cost

Setting Standard Costs Accountants, engineers, purchasingagents, and production managerscombine efforts to set standards that encourage efficient future production.
I recommend using practical standards that are currently attainable with reasonable and efficient effort. Should we useideal standards that require employees towork at 100 percent peak efficiency? Setting Standard Costs Engineer ManagerialAccountant

Setting Standards In recent years, TQM advocates have soughtto eliminate all defects and waste, rather than continually build them into standards. As a result allowances for waste andspoilage that are built into standardsshould be reduced over time.
RateStandards TimeStandards Often a singlerate is used that reflectsthe mix of wages earned. Use time and motion studies foreach labour operation. Setting Direct Labour Standards
RateStandards ActivityStandards The rate is the variable portion of the predetermined overhead rate. The activity is the base used to calculate the predetermined overhead. Setting Variable Overhead Standards
Standard Cost Card – Variable Production Cost A standard cost card for one unit of product might look like this:
Astandardis a per unit cost. • Standards are often used when preparing budgets. Standards vs. Budgets Are standards the same as budgets? A budget is set for total costs.
The purchasing manager is responsible for raw material purchase prices and the production manager is 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 a period of time before being used in production. Price and Quantity Standards Price and and quantity standards are determined separately for two reasons:

Material Variances Example Glacier Peak Outfitters has the following direct material standard for the fiberfill in its mountain parka. 0.1 kg. of fiberfill per parka at $5.00 per kg. Last month 210 kgs of fiberfill were purchased and used to make 2,000 parkas. The material cost a total of $1,029.

Material Variances:Using the Factored Equations Materials price variance MPV = AQ (AP - SP) = 210 kgs ($4.90/kg - $5.00/kg) = 210 kgs (-$0.10/kg) = $21 F Materials quantity variance MQV = SP (AQ - SQ) = $5.00/kg (210 kgs-(0.1 kg/parka 2,000 parkas)) = $5.00/kg (210 kgs - 200 kgs) = $5.00/kg (10 kgs) = $50 U
Purchasing Manager Production Manager Responsibility for Material Variances Materials Quantity Variance Materials Price Variance The standard price is used to compute the quantity varianceso that the production manager is not held responsible forthe purchasing manager’s performance.
Your poor scheduling sometimes requires me to rush order material at a higher price, causing unfavorable price variances. I am not responsible for this unfavorable materialquantity variance. You purchased cheapmaterial, so my peoplehad to use more of it. Responsibility for Material Variances
Zippy Quick Check Hanson Inc. has the following direct material standard to manufacture one Zippy: 1.5 pounds per Zippy at $4.00 per pound Last week 1,700 pounds of material were purchased and used to make 1,000 Zippies. The material cost a total of $6,630.
Zippy Quick Check Hanson’s material price variance (MPV)for the week was: a. $170 unfavorable. b. $170 favorable. c. $800 unfavorable. d. $800 favorable.

I’ll start computingthe price variancewhen material ispurchased rather thanwhen it’s used. I need the price variancesooner so that I can betteridentify purchasing problems. You accountants just don’tunderstand the problems thatpurchasing managers have. Isolation of Material Variances
The price variance is computed on the entire quantitypurchased. • The quantity variance is computed only on the quantityused. Material Variances Hanson purchased and used 1,700 pounds. How are the variances computed if the amount purchaseddiffers from the amount used?
Zippy Quick Check Continued Hanson Inc. has the following material standard to manufacture one Zippy: 1.5 pounds per Zippy at $4.00 per pound Last week 2,800 pounds of material were purchased at a total cost of $10,920, and 1,700 pounds were used to make 1,000 Zippies.
Zippy Price variance increases because quantity purchased increases. Price variance$280 favorable Quick Check Continued Actual Quantity Actual QuantityPurchased Purchased× ×Actual Price Standard Price 2,800 lbs. 2,800 lbs. × × $3.90 per lb. $4.00 per lb. = $10,920 = $11,200

Further Analysis of Materials Variances: Mix and Yield When the production process requires the input of more than one material, the material quantity variance (MQV) can be further broken down into mix variance and yield variance.
Mix and Yield Variances Actual Quantity Actual Quantity Standard Quantity @ Std. Mix (M) × × × Standard Price Standard Price Standard Price Mix Variance Yield Variance Material Quantity Variance SP(AQ - M) SP(M - SQ) AQ = Actual QuantityM= AQ @ Std. MixSP= Standard PriceSQ = Standard Quantity
Example of Mix and Yield Variances • One unit of finished goods requires the following input mix: • 2 kgs of A with a standard price of $1.50/kg • 3 kgs of B with a standard price of $2.50/kg • The standard mix is thus 2A:3B • During the period, 150 units of finished goods were produced using 350 kgs of A and 450 kgs of B.
Mix and Yield Variances • Mix Variance: SP(AQ - M) Material A: $1.50 x [350 – 2/5 (350 + 450)] = $45 U Material B: $2.50 x [450 – 3/5 (350 + 450)] = $75 F • Yield Variance: SP(M - SQ) Material A: $1.50 x [2/5 (350 + 450) – 150(2)] = $30 U Material B: $2.50 x [3/5 (350 + 450) – 150 (3)] = $75 U • Material Quantity Variance: SP(AQ - SQ) Material A: $1.50 x [350 – 150(2)] = $75 U Material B: $2.50 x [450 – 150 (3)] = $-0- U
Labour Variances Example Glacier Peak Outfitters has the following direct labour standard for its mountain parka. 1.2 standard hours per parka at $10.00 per hour Last month employees actually worked 2,500 hours at a total labour cost of $26,250 to make 2,000 parkas.
