Life Cycle Cost (LCC)

Acquisition cost is only the visible part of what a system will actually cost. Operation and maintenance typically account for 60 to 70 percent of total life cycle cost, which means decisions made early, and throughout, a program's life have a far greater financial impact than the purchase price alone suggests. Life Cycle Cost (LCC) analysis and modelling make that full cost visible, so decisions can be based on total cost rather than upfront price.

What is Life Cycle Cost (LCC)?

Life Cycle Cost is the total cost of owning and operating a system across its entire life, from acquisition through operation, maintenance, support, and eventual disposal. Because acquisition cost is typically only the "top of the iceberg," an LCC perspective is essential for understanding the true cost impact of design, procurement, and support decisions before they are made, not after.

Why a life cycle perspective is essential

Decisions made early in a system's life cycle are the most decisive for its long-term cost effectiveness. But later-phase decisions matter too: upgrades, revised maintenance strategies, new support contracts, or changing usage patterns can all significantly affect the remaining life cycle cost. Any decision involving a significant change to these factors should be evaluated for its LCC impact, not just its immediate cost.

Life Cycle Cost Modelling

Life cycle cost modelling is the structured methodology for analyzing total cost of ownership across a system's full lifespan. A robust model captures every significant future cost category, acquisition, operation, maintenance, support, and disposal, so that decisions are based on complete information rather than partial estimates.

Effective LCC modelling depends on structured data, clearly defined cost breakdown structures, and consistent modelling principles. Opus Suite+ provides a single environment for building and managing these models: defining cost breakdown structures, setting parameters and assumptions, and maintaining traceable links between technical, operational, and financial data.

Sensitivity analysis and scenario modelling

Opus Suite+ supports sensitivity analysis, scenario modelling, and baseline management, allowing organizations to identify cost drivers and quantify uncertainty. Decision makers can evaluate how changes in reliability, maintenance concepts, operating profiles, or supply strategies affect total cost of ownership, testing alternative assumptions to reduce risk and improve financial predictability.

Life Cycle Cost in Procurement

LCC is not just a cost model, it is a procurement strategy. Rather than evaluating tenders on purchase price alone, LCC-based procurement evaluates the total cost commitment of an investment: acquisition, operation, maintenance, and disposal combined. EU procurement legislation, among other frameworks, explicitly allows evaluation based on "the most economically advantageous" solution rather than lowest price, making a structured LCC approach both a financial and a compliance advantage.

This approach has been used in practice: Systecon led the LCC evaluation strategy in the procurement of new C30 subway trains for the Stockholm County Council, where LCC was established as the backbone of the tender evaluation, with bidders required to submit cost and performance information within a shared LCC model structure.

How Opus Suite+ supports Life Cycle Cost analysis

Opus Suite+ is used across defense and other industries worldwide, in every phase of the system life cycle, to model, simulate, and evaluate how design, maintenance, and support decisions affect cost and performance over time. Within Opus Suite+, teams can:

Model and simulate the cost impact of decisions
Compare alternative solutions side by side
Identify cost drivers and the most cost-effective improvements
Evaluate financial risk and sensitivity to data uncertainty
Support budgeting and forecasting

Cost structure, complexity, formulas, and KPIs are fully tailorable to the scope of the analysis. A simple model using rough estimates and default values, typical for early budget planning, can be refined progressively as more detailed data becomes available and understanding improves.

Frequently Asked Questions

What is Life Cycle Cost (LCC)?

Life Cycle Cost is the total cost of owning and operating a system across its full life, including acquisition, operation, maintenance, support, and disposal. It provides a complete financial picture beyond the initial purchase price.

Why does operation and maintenance cost matter more than acquisition cost?

Operation and maintenance typically account for 60 to 70 percent of a system's total life cycle cost. Acquisition cost, while visible upfront, is usually the smaller portion of total cost, making it essential to evaluate decisions against their full life cycle impact rather than purchase price alone.

How is LCC used in procurement?

LCC-based procurement evaluates tenders on total cost of ownership rather than purchase price alone. This is supported by procurement frameworks such as EU legislation, which allows evaluation based on the most economically advantageous solution, and has been applied in practice, including in the Stockholm County Council's C30 subway train procurement.

What is the difference between LCC analysis and LCC modelling?

LCC analysis is the broader discipline of evaluating cost impact across the life cycle. LCC modelling is the structured methodology and toolset used to build that analysis, defining cost breakdown structures, assumptions, and calculations that can be refined in detail as a program progresses.

How does Opus Suite+ support Life Cycle Cost analysis?

Opus Suite+ provides a single environment for building LCC models, running sensitivity and scenario analysis, and comparing alternatives, integrated with the same platform used for reliability, maintenance, and logistics analysis. This means life cycle cost is evaluated using data that stays consistent with other supportability decisions rather than as a standalone spreadsheet exercise.
