Introduction to Life Cycle Costing: Meaning and Objectives

Updated 11 October 2026 · Fact-checked

Life cycle costing (LCC) tracks and accumulates all costs of an asset or product over its whole life, from design and development to operation, maintenance and disposal. You solve questions by listing costs phase-wise, adding them, spreading them over units or years, and comparing options on total life cost, not purchase price alone.

Understand Introduction to Life Cycle Costing

Most businesses judge an asset or product by its purchase price or its cost in the current year. That view is narrow. A cheap machine can be costly to run, repair and dispose of. A product can look profitable in a year but lose money over its life.

Life cycle costing fixes this by looking at all costs from the start of an idea to the end of the item's life. It covers costs before production (research, design, development), during life (purchase or production, operation, maintenance, marketing) and at the end (decommissioning, disposal, or clean-up). Some versions also include costs the customer bears after purchase, such as running and servicing costs.

A key idea is cost commitment. Most of a product's life cost is locked in early, at the design stage, even though it is spent later. Decisions made in design fix the material, process and maintenance needs. So the best time to cut life cost is before the product is made, not on the shop floor.

Objectives of LCC are to:
- find the total cost over the whole life, not one period
- support decisions on buying, designing, pricing and replacing
- identify cost-reduction chances early, at design stage
- check whether the product recovers all its life costs and earns a target profit
- compare alternatives fairly on total cost.

Traditional cost accounting is period-based. It reports costs for a year or a batch, treats research and design costs as period expenses, and often ignores post-purchase and disposal costs. LCC is product-based or asset-based, covers all phases, and keeps pre-production and end-of-life costs visible against the item they belong to.

Benefits: better pricing, visibility of hidden costs, better design choices, and sounder investment and replacement decisions. Limitations: it needs long-term estimates that may prove wrong, data collection is heavy, it can be hard to trace costs across years, and the time value of money may be ignored unless you discount.

Key rules to remember

Total life cycle cost: Life cycle cost = Pre-production costs + Production/acquisition costs + Operation and maintenance costs + Disposal costs; Add every phase. Use the cost heads given in the question; do not invent extra ones.
Life cycle cost per unit: LCC per unit = Total life cycle cost ÷ Total units produced over life; Use lifetime units, not one year's units.
Life cycle profit check: Life cycle profit = Total life revenue − Total life cycle cost; A product must recover all phases, including design and disposal, before it earns a true profit.
Discounted life cycle cost: PV of LCC = Σ [Cost in year t ÷ (1 + r)^t]; Use when the question gives a discount rate and costs fall in different years.

How to solve Introduction to Life Cycle Costing questions

Use this method for any question on meaning, comparison or calculation in life cycle costing.

1Read the question and decide whether it asks for theory (meaning, objectives, benefits, difference from traditional costing) or a calculation.
2For theory, define LCC first, then cover the phases, then answer exactly what is asked (objectives, benefits, limits or comparison).
3For a comparison with traditional costing, use clear points: time frame, cost coverage, treatment of R&D and disposal, focus and decision use.
4For a calculation, sort the given costs into phases: pre-production, production or acquisition, operation and maintenance, and disposal.
5Check the timing. If costs fall in different years and a discount rate is given, find present values before adding.
6Add the costs to get total life cycle cost, then divide by lifetime units if a per-unit figure is needed.
7Compare with revenue or with other options and state a clear recommendation.
8Write one line of conclusion linking the result to the decision, such as price, design change or choice of asset.

Quickest way: Phase-wise sum and compare

When to use it: Use for short numerical or MCQ questions where you must choose between two options or find per-unit life cost.

Draw a quick list of four phases: before production, production or purchase, running, disposal.
Put each given figure in its phase and check no figure is left out.
Add each option's total. Discount only if the question gives a rate.
Divide by lifetime units if needed.
Pick the lower total cost (or higher life profit) and state it in one line.

Common mistakes in Introduction to Life Cycle Costing

Treating LCC as the same as the purchase price or one year's cost.
Traditional costing is period-based, so students carry that habit over.
Fix: Always say LCC covers all phases from design to disposal, and add all of them.
Leaving out R&D, design or disposal costs in the total.
These costs are not part of normal production cost sheets.
Fix: Scan the question for every cost item and place each in a phase before adding.
Dividing total life cost by one year's units.
Students use the units that are most visible in the data.
Fix: Divide by total units over the whole life.
Ignoring time value of money when a discount rate is given.
The idea feels like simple cost addition.
Fix: If a rate is given, find present value of each year's cost before totalling. If none is given, add nominal values.
Saying most cost is incurred at the design stage.
Cost commitment and cost incurrence get mixed up.
Fix: Say most cost is committed (locked in) at design, though it is spent later.
Writing a one-sided answer on benefits and limitations.
Students remember the advantages and skip the weaknesses.
Fix: Give both sides, with at least three points each, and link each to a decision.

Worked examples

Example 1

A company plans to launch a product. Estimated lifetime costs: R&D and design ₹12,00,000; production ₹48,00,000; marketing and distribution ₹15,00,000; after-sales service ₹6,00,000; discontinuation and disposal ₹3,00,000. Lifetime sales are expected to be 20,000 units at ₹450 per unit. Find the life cycle cost per unit and the life cycle profit. Ignore time value of money.

Show the solution

Total life cycle cost = 12,00,000 + 48,00,000 + 15,00,000 + 6,00,000 + 3,00,000 = ₹84,00,000.
Life cycle cost per unit = 84,00,000 ÷ 20,000 = ₹420.
Life revenue = 20,000 × ₹450 = ₹90,00,000.
Life cycle profit = 90,00,000 − 84,00,000 = ₹6,00,000.
Profit per unit = 450 − 420 = ₹30, which agrees with ₹6,00,000 ÷ 20,000.

Answer: Life cycle cost per unit is ₹420 and life cycle profit is ₹6,00,000. The price of ₹450 recovers all life costs, including R&D and disposal, with a thin margin of ₹30 per unit.

Example 2

Distinguish life cycle costing from traditional cost accounting, and state two benefits and two limitations of life cycle costing.

Show the solution

Time frame: traditional costing reports cost for a period (a year or a batch). LCC accumulates cost over the whole life of the product or asset.
Coverage: traditional costing focuses on production cost and usually writes off R&D and design as period costs. LCC includes pre-production, operation, after-sales and disposal costs.
Focus: traditional costing controls cost during production. LCC stresses planning and design, where most cost is committed.
Decision use: traditional costing suits short-term control. LCC suits pricing, design, investment and replacement decisions.
Benefits: it shows hidden costs and gives a true profitability view over the life; it directs cost reduction to the design stage.
Limitations: it depends on long-term estimates that may be wrong; it needs detailed data and tracing of costs across years, which is costly.

Answer: Traditional costing is period-based and production-focused; LCC is life-based and covers every phase from design to disposal. LCC gives a truer view of profitability and early cost control, but relies on uncertain forecasts and heavy data collection.

Exam tips

For a 'distinguish' question, write in short points under clear heads such as time frame, coverage and decision use. Examiners reward structure.
In MCQs, watch the words 'committed' and 'incurred'. Most life cost is committed at design, not incurred.
In numerical questions, tick off every cost given against a phase so none is missed, and use lifetime units for the per-unit figure.
End application answers with a recommendation, for example price, redesign or choose the lower life cost option.
Keep one line each ready for meaning, objectives, benefits and limitations; these are the usual theory asks.

Introduction to Life Cycle Costing: frequently asked questions

What is life cycle costing in simple words?

It is a way of adding up all costs of a product or asset over its entire life, from design to disposal. You use it to see the true cost and decide on price, purchase or replacement.

How is life cycle costing different from traditional costing?

Traditional costing looks at cost period by period and mostly at production. Life cycle costing looks at the whole life and includes design, after-sales and disposal costs. It is therefore better for long-term decisions.

What are the main objectives of life cycle costing?

The main aims are to find total cost over the life, support pricing and investment decisions, cut cost early at the design stage, and check that all life costs are recovered with a profit.

What are the limitations of life cycle costing?

It relies on long-term estimates that can go wrong. It also needs a lot of data and cost tracing across years, and it may ignore the time value of money unless you discount the costs.
