Question

Calculating the Direct Materials Price Variance and the Direct Materials Usage Variance Guillermo's Oil and Lube Company is a service company that offers oil changes and lubrication for automobiles and light trucks. On average, Guillermo has found that a typical oil change takes 24 minutes and 6.2 quarts of oil are used. In June, Guillermo's Oil and Lube had 980 oil changes. Guillermo's Oil and Lube Company provided the following information for the production of oil changes during the month of June:

Actual number of oil changes performed: 980
Actual number of quarts of oil used: 6,020 quarts
Actual price paid per quart of oil: $5.10
Standard price per quart of oil: $5.05

Required:
a. Calculate the direct materials price variance (MPV) and the direct materials usage variance (MUV) for June using the formula approach.
b. Calculate the total direct materials variance for oil for June.

Answer 1

Answer:

Results are below.

Explanation:

To calculate the direct material price variance, we need to use the following formula:

Direct material price variance= (standard price - actual price)*actual quantity

Direct material price variance= (5.05 - 5.1)*6,020

Direct material price variance= $301 unfavorable

To calculate the direct material quantity variance, we need to use the following formula:

Direct material quantity variance= (standard quantity - actual quantity)*standard price

Direct material quantity variance= (6,076 - 6,020)*5.05

Direct material quantity variance= $282.8 favorable

Standard quantity= 980*6.2= 6,076

Finally, the total direct material variance:

Total direct material variance= Direct material quantity variance - Direct material price variance

Total direct material variance= 282.8 - 301

Total direct material variance= $18.2 unfavorable
