Ba2 Flashcards
Direct Costs
Clearly Identified with the cost object
Prime Cost
Total of all direct costs
Indirect costs
cannot be directly linked to cost unit but clearly incurred in production
fixed cost
cost unaffected by movement in activity
stepped fixed cost
if production grows, fixed cost increases
variable cost
varies with measure of activity
semi variable cost
fixed costs with additional add ons
high low method
find the difference between the highest and lowest activity levels and their respective costs
find variable cost per unit
multiply this by highest activity level to get total variable cost and subtract from total to get fixed
regression analysis y=a+bx
y= total cost
a= fixed cost
b= variable cost per unit
x= activity level
coefficient of determination
r^2 = gives the proportion of changes in y that can be explained by changes in x
relevant costs
costs affected by managerial decision
irrelevant cost
costs that will not change in the future when you make one decision vs another
overheads
these are the same as indirect costs
total cost per unit
direct costs(prime) + overheads
production overheads
indirect costs incurred by the production function
service cost centres
cost centres that are part of production but not directly involved
absorption costing
allocation and apportionment, reapportionment and absorption of overheads
apportioned costs
(total overhead cost/total value of apportionment base) x value of apportionment based off the cost centre being calculated
reapportionment
ratio based of how much should be apportioned to each production centre
absorption of overheads
measure the level of production achieved
work out the OAR
multiply this by hours/units used to get overhead absorbed by cost unit
OAR
production cost centre overhead/ quantity of absorption base
reciprocal servicing
when we need to apportion the costs of multiple service centres
under/over absorption
the amount of overhead could be more/less than budgeted
the quantity of the absorption base could have been more/less than budgeted
overheads absorbed
budgeted OAR x actual hours/units
under/over absorption calc
amount absorbed- actual cost incurred
marginal costing
the additional cost incurred in producing one additional unit of the product including total variable costs but NOT fixed overheads
contribution
sales value - variable costs
total contribution
contribution per unit x sales value
profit
total contribution - fixed costs
profit for absorption costing
opening and closing inventory are valued at full production cost
and adjustment for under/over absorption of overheads is necessary
profit of marginal costing
opening and closing inventory are valued at marginal production cost
if there are variable non production costs these would be deducted before contribution but not included in cost of sales
fixed costs actually incurred are deducted from contribution earned
Costing affects on inventory
inventory levels increase- absorption gives higher profit
inventory levels decrease- marginal gives higher profit
