Life Cycle Cost
The Life cycle cost, which is also known as cradle to
grave cost,is the total cost from acquisition of an itemto the final disposal of the same after the life of the
item. The elements of Life cycle cost can be narrated
as:
1. Acquisition cost
2. Operational cost
3. Maintenance cost
4. Repair and replacement cost
5. Salvage cost

Appreciation of Money Concept
If Rs 100 is invested in the bank at the interest rate of 10 per
cent on the first day of the year, then at the end of the year,it will become Rs 110. In other words, the present value of
Rs 110, at the end of the year, is Rs 100
YearAmount at Start
of Year Interest RateAmount at End of
Year
1 100 10 % 110
2 110 10 % 121
3 121 10 % 133.1
4 133.1 10 % 146.31

Appreciation of Money Concept
The present value (beginning of the 1st year)
of Rs 146.31 (at the end of 4th year) is Rs
100.00. In a mathematical expression, the
factor which when multiplied by Rs 144.10 will
give Rs 100.00 is known as the PresentWorthFactor. In this case, it will be 0.6835
(100.00/146.31 = 0.6835).

Appreciation of Money Concept
Similarly, if one wants to distribute the present value
at the beginning of the year into all the four years (asin this case), the present value has to be multiplied
with a factor which is known as the CapitalRecovery
Factor. If one has to distribute the present worth of
Rs100.00 into four equal installments, the multiplying
Capital recovery factor will be 0.3165 for the interest
rate of 10 per cent.

Methods of Calculating Life Cycle Cost
There are two methods of calculating the Life cycle
cost. These are:
1. Present worth Method
2. Annualized Method
-

10/38
Procedure of Calculating LCC ; Present Worth Method
Acquisition cost: Since the acquisition cost is in the first day
of the calendar year, it is the present worth and its Presentworth factor is 1.
Operation and maintenance cost: These costs take place
every year. Using the discount rate and the year when
operation and maintenance cost recur, find out the Present
worth factor. Multiply the costs with those factors to achieve
the present worth of the individual item.
Repair and replacement cost: These are single payments
which may happen at any time of the life cycle. Using the
discount rate and the year when repair and replacement costrecur, find out the Present worth factor. Multiply the costs with
those factors to achieve the present worth of the individual
item.

Procedure of Calculating LCC ; Present Worth Method
Salvage value: This will happen at the end of the life
cycle. This is the only item which is an income, when allothers are expenses. Using the discount rate and the
year when it is being salvaged, find out the Present
worth factor. Multiply the salvage value with that factor
to achieve the present worth of the item.
Life cycle cost: To arrive at the Life cycle cost, addall the 3 items from last slide, then deduct item 4 from
(salvage value) that total.

Procedure of Calculating LCC ; Annualized Method
Acquisition cost: Since the acquisition cost is in the first day of
the calendar year, it is the present worth. To get theannualized cost, it has to be multiplied by the Capital recovery
factor based on discount rate and the life of the items.
Operation and maintenance cost: These costs happen every
year. Hence, they do not require any further treatment.
Repair and replacement cost: These are single payments
which may happen at any time of the life cycle. Using the
discount rate and the year when repair and replacement cost
recur, fi nd out the Present worth factor. Multiply the costs with
those factors to achieve the present worth of the individualitem. To get the annualized cost, it has to be multiplied by the
Capital recovery factor based on discount rate and the life of
the items.

Procedure of Calculating LCC ; Annualized Method
Salvage value: This item will happen at the end of the
life cycle. This is the only item which is an income,when all others are expenses. Using the discount rate
and the year when it is being salvaged, find out the
present worth factor. Multiply the salvage value with
that factor to achieve the Present worth of the item. Toget the annualized cost, it has to be multiplied by the
capital recovery factor based on discount rate and the
life of the items.
Life cycle cost: To arrive at the Life cycle cost, addall the 3 items from last slide, then deduct item 4 from
(salvage value) that total.

Limitations of Life Cycle Costing
Life of the item: Determining the life of an item is difficult.
Interest rate: The interest rate may not be same every year.
Annual expenses: Annually operation and maintenance costsare assumed as the expenses occurring at the end of the year
while calculating the LCC. Intermediate expenses are not
taken into consideration.
Quality/reliability: Not considering the quality and reliability ofthe item, since the focus is only on costs. The lowest LCC item
may not be a good quality item.
Aesthetic: Not focusing on the esteem value of the item
Hence, the lowest LCC item may fail to add to the esteem of
the owner even though it provides the use value.
Comfort and safety: The comfort and safety of the customer
are not considered while determining the LCC. Hence, there is
a chance that the lowest LCC item may not provide sufficient
comfort/safety resulting in poor value to the customer.

Following are the two types of VE / VA techniques
which are most commonly used
FUNCTIONCOSTWORTH ANALYSIS

The Functioncostworth analysis is an excellent
tool to identify the value improvement potential in
any function.
This tool will not only help to identify the potential
but will also give some creative ideas as to how to
achieve that.
The ultimate aim of the Functioncostworth
analysis is to find out the value improvement in
various functions. Based on these findings, the team
will approach the problem.
FUNCTIONCOSTWORTH ANALYSIS

Worth is the minimum cost of achieving a function.
Worth is an indispensable element of VE.
Worth varies with time.
Worth depends upon information.
Worth is usually determined by developing or thinking
of other methods of performing functions.
Worth is just a technique, not an absolute value.
Where an item has several functions, determine
worth of each function separately and add them to
get overall worth.
Concept of Worth
-

18/38
Split the product into components and service/system into activities.
Define functions of components/activities.
Divide the total cost of product/service/system into components/
activities cost.
Processes performed to achieve particular function; cost allocated to
that function.
Component provided to achieve particular function; cost allocated to
that function.
Component accomplishes more than one function; allocation should
be based on weight, volume, surface area and length.
Hold each function in isolation of the others to do this.
Procedure for Cost Allocation

The difference between cost and worth is known as
valuegap. It indicates the scope of possible value
improvement.
The value index is the ratio of cost by worth. In
other words, it is the cost per unit of worth. When
the index is more than one, it means there is
potential for value improvement.
Value Gap and Value Index

Write down all functions for the project as a whole.
Divide the project into parts.
Function(s) of each part to be defined in two words.
An active verb and a measurable noun.
Apply three tests to identify the basic and secondary functions.
Is this function what users are looking for?
Yes: Basic No: Secondary
If this function is eliminated, will the item continue to do the job?
No: Basic Yes: Secondary Will the function disappear, if the design approach is changed?
No: Basic Yes: Secondary
Steps for functioncostworth analysis

Cost of each part to be ascertained.
Cost of the part to be transformed into function.
Check whether the cost of the functions are equal to the sum
of the costs of the parts.
Assess the worth (least cost of achieving) functions. First list all functions and costs in descending order.
Then ask the following questions:
Will you pay if it is your money?
If not, what do you consider reasonable?
By whom or where a similar function is available at lower cost?
What should you do to obtain the function within that cost?

A key point of the organized VE effort is the use of
the Job Plan. The Job Plan is the organized
problem-solving approach that separates VE from
other cost-cutting exercises. The simplest Job Plan
follows a five-step approach that is integral to VE
methodology. Key questions are answered at each
stage.
