What is Lifecycle Costing?
Lifecycle costing tracks and accumulates all costs a product incurs across its entire life, from design and development through production, distribution, customer support, and eventual disposal. It gives managers a full picture of profitability beyond just manufacturing cost.
Lifecycle costing sums every cost a product generates over its life — development, production, distribution, service, and disposal — to reveal true total profitability.

Step-by-step worked examples
A product has $150,000 development cost, $400,000 manufacturing cost, and $50,000 disposal cost. What is total lifecycle cost (ignore other categories)?
TLC = Cd + Cm + Cr TLC = 150,000 + 400,000 + 50,000 = $600,000
If a product generates $900,000 in lifetime revenue and its total lifecycle cost is $600,000, what is lifecycle profit?
Lifecycle profit = Lifetime revenue − Total lifecycle cost = 900,000 − 600,000 = $300,000
A company spends $200,000 on R&D upfront but saves $50,000 in customer service costs by improving design. What is the net lifecycle cost impact?
Net impact = Extra development cost − Service cost saved = 200,000 − 50,000 = $150,000 net increase in lifecycle investment, but better product quality

Common mistakes
Lifecycle costing only counts manufacturing costs. — Correct: It includes design, manufacturing, distribution, service, and disposal costs across the entire life.
Disposal costs are irrelevant to profitability. — Correct: Disposal/retirement costs can be significant (e.g., environmental cleanup) and must be included.
Lifecycle costing and traditional costing give the same total. — Correct: Traditional costing typically misses pre-production and post-production costs, understating true cost.
R&D spending doesn't affect lifecycle cost decisions. — Correct: Higher R&D can lower future service/disposal costs — a key lifecycle costing trade-off.
FAQ
What is lifecycle costing?
Lifecycle costing is a method that accumulates all costs a product incurs from design and development through production, distribution, service, and disposal.
What is the lifecycle costing formula?
Total Lifecycle Cost = Development + Manufacturing + Distribution + Customer Service + Retirement/Disposal costs.
What are examples of lifecycle costing?
Comparing two product designs by their total costs — including future service and disposal — rather than just upfront manufacturing cost, is a classic example.
How do you calculate lifecycle costing?
Sum every cost category a product incurs across its life stages: development, manufacturing, distribution, service, and disposal.
