Elinkaarikustannusstandardit, or life cycle costing standards, are guidelines used to estimate and compare the total cost of ownership of a product or service over its entire life cycle. These standards aim to provide a comprehensive view of costs, including initial purchase, installation, operation, maintenance, and disposal or recycling. They are particularly useful in decision-making processes, such as procurement, investment, and project evaluation, by ensuring that all relevant costs are considered.

The International Organization for Standardization (ISO) has developed several standards related to life cycle costing. ISO 15686, for instance, provides a framework for life cycle costing, including principles, requirements, and guidelines. It emphasizes the importance of considering all costs associated with the product or service, as well as the uncertainty and variability in cost estimates.

Other relevant standards include ISO 14040 and ISO 14044, which focus on life cycle assessment (LCA). While LCA primarily addresses environmental impacts, it also considers costs as part of the overall assessment. These standards are widely used in various industries, including manufacturing, construction, and infrastructure, to support sustainable and cost-effective decision-making.

In practice, applying life cycle costing standards involves several steps. First, the life cycle of the product or service is defined, including all relevant stages from conception to disposal. Next, costs associated with each stage are estimated, taking into account factors such as inflation, technological changes, and market conditions. Finally, the total life cycle cost is calculated and compared with other options to make informed decisions.

Life cycle costing standards are essential for organizations seeking to optimize their resource use, reduce costs, and enhance sustainability. By providing a structured approach to cost estimation, these standards help ensure that all relevant costs are considered, leading to more accurate and reliable decision-making.
