Thompson Manufacturing uses standard costing. It allocates manufacturing overhead (both variable and fixed) to products on the basis of standard direct manufacturing labor-hours (DMLH).

More info

Thompson develops its manufacturing overhead rate from the current annual budget. The manufacturing overhead budget for 2020 is based on budgeted output of 660,000 units, requiring 3,300,000 DMLH. The company is able to schedule production uniformly thorughout the year. A total of 68,000 output units requiring 322,000 DMLH was produced during August 2020. Manufacturing overhead (MOH) costs incurred for August amounted to $376,700.

The actual costs, compared with the annual budget and 1/12 of the annual budget, are as follows:

1. Calculate total manufacturing overhead costs allocated.

Begin by computing the budgeted hours per unit. Determine the formula, then compute the amount.

Requirement

Calculate the following amounts for Thompson Manufacturing for August 2020:
1.	Total manufacturing overhead costs allocated
2.	Variable manufacturing overhead spending variance
3.	Fixed manufacturing overhead spending variance
4.	Variable manufacturing overhead efficiency variance
5.	Production-volume variance
Be sure to identify each variance as favorable (F) or unfavorable (U).
