Definition
The basis of apportionment refers to the methodology used to distribute shared costs equitably among multiple cost centers where direct assignment of overheads is unfeasible. This mechanism is pivotal in ensuring fairness and accuracy in cost accounting, especially relating to inescapable overheads like rent and business rates which are not incurred by specific cost centers. Common criteria used for this purpose include floor area, manpower, machine usage hours, or energy consumption, depending on which metric most accurately reflects the cause of the cost in question.
The Need for Basis of Apportionment
Picture this: a company operates with multiple divisions under one roof, all sharing the same heating system. It’s not like each department has its own thermostat (though some might like the temperature hot enough to grow bananas!). Here’s where the basis of apportionment comes in, acting as the fair-play referee, ensuring everyone pays their share of the gas bill, proportional to their square footage, personnel, or tropical fruit ambitions.
Practical Application
To put it in real-world terms, consider a business that rents a large office space. The marketing department sprawls over the top floor with panoramic views (possibly to draw inspiration from the clouds), while the tech team is huddled in the basement, possibly to keep the servers—and their temperaments—cool. Allocating costs like rent or utilities based solely on headcount or departments would be visually fair but financially misrepresentative. Using a floor area as a basis of apportionment ensures that each department contributes to overheads in proportion to the space they luxuriously or cozily occupy.
Complexities in Apportionment
Selecting the appropriate basis requires a blend of art, science, and possibly a sprinkle of wizardry. It’s about striking the perfect balance between causality and simplicity. An overly simplistic approach might ignore significant cost drivers, while an excessively complex system could confuse more than clarify—leaving everyone bickering over decimals instead of driving departmental synergies.

In cost accounting, as in life, fairness isn’t about everyone getting the same but about everyone getting what they need to succeed. The basis of apportionment ensures just that, even if sometimes it means counting square feet or monitoring machine hums to get there.
