kostenmodellering

Kostenmodellering is a methodological approach used in management accounting to estimate and represent the costs associated with products, services, processes, or projects. It supports budgeting, pricing, procurement, and strategic decision making by providing a structured view of where costs arise and how they behave over time.

The practice relies on concepts such as cost objects, cost drivers, and cost pools. It distinguishes fixed and variable costs as well as direct and indirect costs. Several modeling approaches are common, including activity-based costing, life-cycle costing, total cost of ownership, and cost-volume-profit analysis. Each approach offers different levels of detail and focuses on different decision contexts.

A typical kostenmodellering process includes defining the objective and scope, selecting the modeling approach, identifying cost objects and drivers, collecting data, estimating costs, allocating costs to drivers, validating the model, and performing sensitivity or scenario analyses. The results are then communicated along with the underlying assumptions to support decision making.

Applications of kostenmodellering range from product development and manufacturing to information technology investments, outsourcing decisions, project financing, and public-sector budgeting. It helps compare alternatives, estimate total costs over an asset’s life, and determine break-even points or required profitability targets.

Data quality and governance are critical for reliable models. Model complexity should align with decision needs, and assumptions should be transparent and well documented. Model risk can arise from incorrect driver selection, biased data, or changes in underlying processes, underscoring the need for ongoing updates and validation.

The term is widely used in Dutch-language contexts but reflects broader international practices in cost modeling for management accounting and cost estimation.
