Example of Using Expense Pools and Cost Element Groups to Calculate Overhead Absorption
This example shows how to use expense pools and cost element groups to define overhead accounting rules, and calculate overhead absorption for transactions.
Scenario
Your cost organization is a bicycle retail store with:
-
Monthly overhead costs of 10,000 USD for rent 500 USD for water, 1,500 USD for electricity, and 1,000 USD for gas.
-
Additional costs of 50 USD freight per incoming receipt; and 10 USD inspection fees per unit.
You want to calculate overhead absorption for 5 transactions during the month:
-
2 receipts of bike X
-
3 receipts of bike Y
Transaction Details
You combine the water, electricity, and gas costs into one utility expense pool of 3,000 USD. Then define the expense pools on the Manage Overhead Expense Pools page as described in this table.
Expense Pool |
Cost Element |
---|---|
Rent |
Warehouse Overhead |
Utilities |
Warehouse Overhead |
Freight |

Warehouse Overhead |
Next, define a Materials cost element group on the Manage Overhead Cost Element Groups page. You use this cost element group to calculate overhead costs as a percentage of material costs. Your material costs are:
-
500 USD per unit for bike X
-
300 USD per unit for bike Y
Finally, you want overhead costs to include cost organization administrative and inventory organization facilities costs.
Analysis
Define the overhead accounting rules and absorption rates so that, for each month, the total amount absorbed by the transactions equals the overhead expense pools.
This table describes the overhead accounting rules and absorption rates:
