The budgeted fixed manufacturing cost per unit and budgeted total manufacturing cost per unit under absorption costing are:
January February March
(a) Budgeted fixed manufacturing costs
(b) Budgeted production
(c) = (a) (b) Budgeted fixed manufacturing cost per unit
(d) Budgeted variable manufacturing cost per unit
(e) = (c) + (d) Budgeted total manufacturing cost per unit 490,000

2. Absorption-costingoperating income Variable costingoperating income = Fixed manufacturingcosts inending inventory Fixed manufacturingcosts inbeginning inventory
January: 1,797,500 1,762,500 = (350 100) 0
35,000 = 35,000
February: 1,899,375 1,899,375 = (350 100) (350 100)
0 = 0
March: 2,036,625 2,045,375 = (350 75) (350 100)
8,750 = 8,750
The difference between absorption and variable costing is due solely to moving fixed manufacturing costs into inventories as inventories increase (as in January) and out of inventories as they decrease (as in March).
