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

Unit costs incurred
Characterization of actual costs:
Direct material ap × aq
Direct labor ar × ah

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)
![Page 8: Introduction to Accounting](https://reader036.vdocuments.mx/reader036/viewer/2022072014/56812d64550346895d927313/html5/thumbnails/8.jpg)
04/19/23 A&MIS 212 8
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

Exercise 10-1: Material sp
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

Exercise 10-1: Material sq
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.

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

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

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
