Introduction to Accounting Standard Costing Session 31 February 21,2002 A&MIS 212
Agenda for Today • Discuss problems assigned and other practice problems • Outline approaches to future problems. A&MIS 212
Unit cost standards Specification of unit cost standards: Direct material sp × sq Direct labor sr × sh Variable OH sr × sq Fixed OH sr × sq Total unit std. cost A&MIS 212
Unit costs incurred Characterization of actual costs: Direct material ap × aq Direct labor ar × ah Variable OH ar × aq Fixed OH ar × aq Total cost incurred per unit A&MIS 212
Other terminology Total quantities: AQ represents total actual quantity AQU represents the total quantity actually used or produced. AQP represents the total quantity purchased A&MIS 212
A budget view of variances Flexible Flexible Budget Budget Actual(AQ input)(SQ input) Cost sp × AQ sp × SQ incurred Actual cost - sp × AQ sp × AQ - sp × SQ A&MIS 212
A Formula View of Variances Total variance = actual – standard cost Total variance = ap × AQ – sp× SQ Price variance = (ap – sp) × AQ Quantity variance = sp(AQ – SQ) A&MIS 212
Algebra of Variances Price variance + quantity variance = total variance = [(ap – sp) × AQ] + [sp × (AQ – SQ)] = ap × AQ – sp × AQ + sp × AQ – sp × SQ = [ap × AQ] – [sp × SQ], the total variance A&MIS 212
Exercise 10-1: Materialsp Cost per 15-gal. Container $115.00 Less 2% discount 2.30 Net cash cost $112.70 Add freight cost ($130/100) 1.30 Total cost per container $114.00 Divide by quarts per container* 60.00 Standard cost per quart $ 1.90 *15 gallons 4 quarts per gallon = 60 quarts A&MIS 212
Exercise 10-1: Materialsq Content per bill of materials 7.6 qts. Allowance for evaporation and spoilage (7.6 qts./0.95 = 8 qts.) 0.4 Total quantity per bottle 8.0 qts. Allowance for rejected bottles (8.0 qts./40 saleable bottles) 0.2 Standard quantity per bottle 8.2 qts. A&MIS 212
Standard Cost of Materials Standard Standard Std. Cost Item Quantity Price Per Bottle Echol 8.2 qts. $1.90/qt. $15.58 A&MIS 212
E10-3: Quantities • AQ (DM) = 20,000 lbs. • AQ (output) = 4,000 units • SQ (DM) = 4,000 units 4.6 lbs./unit = 18,400 lbs. • SQ (DL) = 4,000 units 0.2 hrs.*/unit = 800 labor hours A&MIS 212
E10-3: Formula Method - DM Materials price variance = AQ (ap – sp) MPV = 20,000 lbs. ($2.35 – $2.50 per lb.) = - $3,000 F Materials quantity variance = sp (AQ – SQ) MQV = $2.50/lb. (20,000 lbs. – 18,400 lbs.) = $4,000 U Total variance = - $3,000 + $4,000 = $1,000 U A&MIS 212
E10-3: Flexible Budget Method Flexible Flexible Budget Budget Actual (AQ input)(SQ input) Cost incurredsp × AQsp × SQ 20,000 lbs. 20,000 lbs. 18,400 lbs. @ $2.35 = @ $2.50 = @ $2.50 = $47,000 $50,000 $46,000 -$3,000 F$4,000 U Price variance Quantity variance A&MIS 212
E10-3: Formula Method - DL Labor rate variance = AQ (ar– sr) LRV = 750 hrs. ($13.90 – $12.00 per hr.) = $1,425 U Labor quantity variance = sr (AQ – SQ) LQV= $12.00/hr. (750 – 800 hrs.) = - $600 F Total variance = $1,425 – $600 = $825 U A&MIS 212
