Vorkalkulationen

Vorkalkulationen, also known as preliminary or forward cost calculations, are systematic estimations of the expenses and revenues associated with a planned product, service, or project before its actual implementation. They serve as a central instrument in cost accounting, strategic planning, and pricing decisions, allowing companies to assess financial feasibility, set appropriate selling prices, and allocate resources efficiently. By projecting the expected costs of materials, labor, overhead, and other inputs, Vorkalkulationen provide a basis for budgeting, cost control, and profitability analysis throughout the product development cycle.

The methodology typically follows a stepwise approach: first, the required output is defined together with technical specifications and production volumes. Second, the necessary inputs are identified and quantified, often based on bill‑of‑materials lists, standard labor times, and historical cost data. Third, unit costs for each input are determined, taking into account price fluctuations, supplier contracts, and economies of scale. Fourth, these unit costs are multiplied by the anticipated quantities and summed to obtain total direct costs. Finally, indirect costs such as administration, depreciation, and contingency allowances are allocated using appropriate distribution keys, resulting in a comprehensive cost estimate for the entire venture.

Vorkalkulationen are distinguished from Nachkalkulationen, which compare actual incurred costs with the original estimates after production has taken place. While forward calculations rely heavily on assumptions and benchmark data, they are essential for decision‑making in product design, market entry, and investment appraisal. Regular updates and sensitivity analyses are recommended to accommodate changes in market conditions, material prices, or technological developments, thereby enhancing the reliability of the forecasts and supporting more informed managerial actions.
