Calculating the Direct Labor Rate Variance and the Direct Labor Efficiency 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 18 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 direct labor hours worked: 286 hours
Actual rate paid per direct labor hour: $14.50
Standard rate per direct labor hour: $13.50
Required:
1. Calculate the direct labor rate variance (LRV) and the direct labor efficiency variance (LEV) for June using the formula approach.

Direct labor efficiency variance (LEV) | $fill in the blank 3 |
2. Calculate the direct labor rate variance (LRV) and the direct labor efficiency variance (LEV) for June.
Direct labor rate variance (LRV) | $fill in the blank 5 | |
Direct labor efficiency variance (LEV) | $fill in the blank 7 |
3. Calculate the total direct labor variance
for oil changes for June.

4. What if the actual wage rate paid in June was $12.50? What impact would that have had on the direct labor rate variance (LRV)? On the direct labor efficiency variance (LEV)? Indicate what the new variances would be below. If required, round your answers to the nearest cent.

Given | |||
Actual hours | AH | 286 | |
Actual Rate | AR | 14.50 | |
Standard Rate | SR | 13.50 | |
Standard Hours | SH | 294 | (18mins/60mins*980 oil changes) |
if the actual wage rate paid in June was $14.5 | |||
Formula | Working | Answer | |
Direct labor rate variance = | (AR-SR) x AH | (14.5-13.5)*286 | $ 286 (A) |
Direct labor efficiency variance = | SR x (AH-SH) | 13.5*(286-294) | $ 108 (F) |
Direct Labour variance = | (SR*SH)-(AR*AH) | (13.5*294) - (14.5*286) | $ 178 (A) |
if the actual wage rate paid in June was $12.50 | |||
Formula | Working | Answer | |
Direct labor rate variance = | (AR-SR) x AH | (12.5-13.5)*286 | $ 286 (F) |
Direct labor efficiency variance = | SR x (AH-SH) | 13.5*(286-294) | $ 108 (F) |
Direct Labour variance = | (SR*SH)-(AR*AH) | (13.5*294) - (12.5*286) | $ 394 (F) |
