What is a cost accountant and what do they do?

Cost accounting is a form of management accounting and is used to understand the fixed and variable costs associated with producing and delivering the goods and services produced by an organisation.

Accountants in this field are specialists who determine the costs associated with providing a service or manufacturing a product by analysing expenses within the supply chain. They measure and record actual costs such as labour, shipping, production and administration, both across a function and at a unit level, to determine the true cost of bringing goods and services to market.

Cost accountants help to plan, budget and monitor performance, set standard unit costs and recommend appropriate cost-saving opportunities. The role is important in understanding where a company is spending money as well as which products, departments or services are most profitable.

Key responsibilities

Responsibilities will vary, but examples include:

  • Collecting and validating data to determine both fixed and variable costs of business activity such as rent, raw material purchases, inventory and labour
  • Analysing changes in product design, raw materials, manufacturing methods or services provided, to determine effects on cost
  • Analysing actual manufacturing costs and preparing periodic reports comparing standard costs to actual production costs
  • Recording cost information for use in controlling expenditures

  • Performing ongoing reconciliations of various cost reports against software systems to ensure accuracy
