ACCA PM: costs at each stage of the product life cycle

This outcome asks you to identify the costs that arise at each stage of a product's life (planning and design, introduction, growth, maturity, decline and final withdrawal) and to say how life-cycle costing treats them. The examiner likes it because it tests whether you can contrast whole-life costing with period-based reporting, which writes costs off as they are incurred.

The rule

Life-cycle costing accumulates all costs and revenues traceable to a product from planning to final withdrawal. Pre-production costs such as R&D and design come first, then launch and marketing costs, then production, support and running costs during growth and maturity, then withdrawal and disposal costs in decline. Traditional period reporting charges each cost to the year it is incurred, so early and late costs are not matched to the product's revenues. Life-cycle costing also shows how much of the total cost is committed at the design stage.

Worked example

A new product has a 4-year sales life. Year 0 (development): R&D $5m. Years 1-4 (sales): contribution after production and support costs is $3m a year. Year 5 (decline): withdrawal costs $1m. Period reporting: year 0 shows a $5m loss, years 1-4 each show $3m profit, and year 5 shows a $1m loss. The product looks poor at first and then excellent. Life-cycle costing: total contribution = 4 x $3m = $12m. Total life-cycle costs outside production = $5m + $1m = $6m. Lifetime profit = $12m - $6m = $6m. The $5m year-0 loss is not evidence that the product is poor. Judge it on the whole-life profit of $6m.
Remember: life-cycle cost includes pre-production costs (R&D) and end-of-life costs (withdrawal, disposal), and post-launch support such as helplines and patches belongs to the product, not to general overheads.

Where candidates lose marks

Try it: 4 questions

Pip Seeds Co develops and sells crop seed varieties. Product X (a new variety) incurred $5m of R&D in year 0, followed by 4 years of sales. Product Y (an established variety) needed little R&D and also has 4 years of sales. Over their whole lives X and Y earn the same total profit. Pip Seeds Co's annual reports are prepared on a period basis, with R&D written off in the year it is incurred.

Which TWO of the following statements correctly compare the annual reports with life-cycle costing?
Select the two that apply (each shows on its own).
Answer: A, B. Period reporting charges each cost to the year in which it is incurred. X's $5m R&D therefore appears as a year-0 loss, with higher profits in later years, while Y's profit is spread evenly. Life-cycle costing accumulates all costs and revenues over the whole life of each product, including pre-production costs such as R&D. On this basis both products earn the same lifetime profit, so neither is inferior. Working: X's later profits exceed Y's by a total of $5m, which offsets the year-0 loss.

Why the others are wrong:
- Option 3 is the trap. It judges X on its early costs and ignores that lifetime profit is equal.
- Option 4 is wrong because period reports do not show whole-life profitability. Life-cycle costing is used precisely to show this.
- Option 5 is wrong because life-cycle costing deliberately includes pre-production costs such as R&D.
Northfield Hospital Trust develops its own patient-booking software. After the system goes live it incurs these costs: a user helpline, bug-fix patches, a minor feature upgrade, and finally the cost of withdrawing support when the system is replaced. Which statement correctly gives the stage and treatment of these costs for life-cycle costing?
Answer: C. Rule: life-cycle cost includes all costs traceable to the product from planning to final withdrawal, including post-launch support. The helpline, patches and upgrade are incurred while the system is in use (maturity). Withdrawal of support occurs at the end of life (decline). All are attributable to the system, so they are included. Option A has the right treatment but the wrong stage: development finishes at launch. Option B treats post-launch support as an unattributed overhead, which understates the system's true lifetime cost. Option D limits the costs to introduction, but a helpline and patches continue throughout use and withdrawal comes at the end.
Bluewave Boats Co is about to launch a new range of motor yachts and is comparing traditional period-based cost reporting with life-cycle costing. Which of the following statements is NOT true?
Answer: B. Rule: traditional reporting is period-based, so R&D and other pre-production costs are usually written off in the periods they are incurred, not collected against the product across its life. Statement B is therefore not true, and it is the answer. Statement A is true: it is the basic distinction between the two approaches. Statement C is true: life-cycle costing shows that most costs are committed in design. Statement D is true: end-of-life costs fall in later periods than the revenues they relate to, so period reporting does not match them.
Hearth Bakeries Co is planning a new range of packaged cakes. Its cost profile shows that only 10% of the total life-cycle cost is spent during the design stage, but about 80% of the total life-cycle cost is already committed by the end of design. Which of the following is the most appropriate conclusion for management?
Answer: A. Rule: the cost incurred (cash spent) at a stage differs from the cost committed (locked in by decisions made). With 80% committed by the end of design, decisions on ingredients, recipes, packaging and processes fix most of the later costs, so design is where cost can be influenced most cheaply. Option B confuses cost incurred with cost committed: by production, most costs can no longer be changed. Option C looks only at the 10% spent and ignores the 80% it commits; cutting design effort may raise later costs. Option D leaves action until most costs are fixed, when little can be changed.

Questions students ask

What costs arise at each stage of the product life cycle?

Planning and design bring R&D and design costs. Introduction brings launch and marketing costs. Growth and maturity bring production, support and running costs, and decline brings withdrawal and disposal costs.

How does life-cycle costing differ from traditional period reporting?

Traditional reporting charges costs to the accounting period in which they are incurred. Life-cycle costing accumulates all costs and revenues of a product over its whole life, so pre-production and end-of-life costs are matched to the product.

Are post-launch costs like helplines and bug fixes included in life-cycle cost?

Yes. They are traceable to the product and arise during maturity, so they are included. Excluding them as overheads would understate the product's lifetime cost.
