The derivation of the price and efficiency variances

AP

ACTUAL COST

AQ

AP = actual price per unit of input (e.g., price per yard). Q = quantity of inputs for total output (e.g., yards).

The flexible budget

SP

FLEXIBLEBUDGET

SQ

SP = budgeted price per unit of input (e.g., price per yard).

SQ = budgeted quantity of inputs required for total output achieved (e.g., total yards of fabric that should have been needed for actual production).

The efficiency (or quantity) variance

QUANTITY VARIANCE


AP = actual price per unit of input. SP = budgeted price per unit of input. Q = quantity of inputs for total output.

The variable cost flexible budget variance decomposes into a “price”

variance and an “efficiency” variance

why price?

Abbreviations:

Price or Wage Rate or Spending Variance = PV

Quantity or Usage or Efficiency Variance = QV

Actual quantity of inputs = AQ

Standard quantity of inputs = SQ

Actual price per input unit = AP

Standard price per input unit = SP





Formulas:

PV = AQ x (AP - SP)

QV = SP x (AQ - SQ)

For direct materials, AQ sometimes refers to materials purchased, instead of materials used. In this case, the price variance and the efficiency variance will not sum to the flexible budget variance, due to the timing difference.

These variances apply to direct materials, direct labor, and variable overhead.

Cost Variances

The McBean Company

The McBean Company makes stars. The budgeted cost for each star is as follows:

Materials: 2 pounds of “star stuff” at $4 per lb. = $8 per starLabor: 1.5 hours at $12 per hour = $18 per star

In December, 1,200 stars were produced. 2,600 lbs. of “star stuff” were purchased at $4.25 per lb. Of this amount, 2,300 lbs. were used in production. Direct labor cost was $20,930 for 1,820 hours.

1. What is the direct material price variance, assuming that the company recognizes the price variance at the time the materials are purchased?2. What is the direct material usage (quantity) variance?3. What is the direct labor rate (price) variance?4. What is the direct labor efficiency variance?

Formulas:

PV = AQ x (AP - SP) QV = SP x (AQ - SQ)

PV = Price Variance QV = Quantity Variance

AQ (SQ) = Actual (Standard) quantity of inputs

AP (SP) = Actual (Standard) price per input

Standards for Direct materials:

2 lbs of “star stuff” at $4 per lb. = $8 per star

In December, 1,200 stars were produced. 2,600 lbs. of “star stuff” was purchased at $4.25/lb. Of this, 2,300 lbs. were used in production. What is the direct material price variance, assuming that the company recognizes the price variance at the time materials are purchased?


2 lbs. of “star stuff” at $4 per lb. = $8 per star

In December, 1,200 stars were produced. 2,600 lbs. of “star stuff” were purchased at $4.25/lb. Of this, 2,300 lbs. were used in production. What is the direct material price variance, assuming that the company recognizes the price variance at the time materials are purchased?

PV = AQ x (AP - SP)

= 2,600 lbs. x ($4.25 per lb. - $4.00 per lb.)

= 2,600 lb. x $0.25 per lb.

= $650 Unfavorable

Formulas:







In December, 1,200 stars were produced. 2,600 lbs. of “star stuff” were purchased at $4.25/lb. Of this, 2,300 lbs. were used in production.

2. What is the direct material usage (quantity) variance?



In December, 1,200 stars were produced. 2,600 lbs. of “star stuff” were purchased at $4.25/lb. Of this, 2,300 lbs. were used in production.

2. What is the direct material usage (quantity) variance?

QV = SP x (AQ - SQ)

= $4 per lb. x (2,300 lbs. - 2,400 lbs.*)

= $4 per lb. x 100 lbs. = $400 favorable

* 2 lbs. per star x 1,200 stars

Formulas:





Standards for Direct labor:

1.5 hours at $12 per hour = $18 per star

In December, 1,200 stars were produced. 2,600 lbs. of “star stuff” were purchased at $4.25/lb. Of this, 2,300 lbs. were used in production. Direct labor cost was $20,930 for 1,820 hours.

3. What is the direct labor rate (price) variance?

Standards for Direct labor: 1.5 hours at $12 per hour = $18 per star


3. What is the direct labor rate (price) variance?

PV = AQ x (AP - SP)

= 1,820 hr.s x (11.50 per hr* - $12 per hr)

= 1,820 hr.s x $0.50 per hr = $910 favorable

* $20,930 ÷ 1,820 hours = $11.50 per hr.

Formulas:

PV = AQ x (SP - AP) QV = SP x (AQ - SQ)




Standards for Direct labor:

1.5 hours at $12 per hour = $18 per star


4. What is the direct labor efficiency variance?

Standards for Direct labor: 1.5 hours at $12 per hour = $18 per star


4. What is the direct labor efficiency variance?

QV = SP x (AQ - SQ)

= $12 per hour x (1,820 hrs - 1,800 hrs*)

= $12 per hour x 20 hrs. = $240 Unfav.

* 1,200 stars x 1.5 hours per star = 1,800 hr.s
