LABOR TURNOVER AND LABOR EFFICIENCY RATIOS
Labor Turnover:
Labor turnover may be defined as the rate of change in the composition of the labor force of an
organisation high rate of labor turnover denotes that labor is not stable and there is frequent
change in the labor force in the organisation. The high labor turnover rate is an important
indication of high labor cost. It is therefore not desirable.
Measurement of Labor Turnover:
There are various methods for the measurement of labor turnover. The choice of method of
measurement would depend on the organisation. But, however, once a particular method is adop-
ted for it, it should be followed for quite some times, so that a clear and comparative picture is
obtained. The methods of measurement are:
(1) Separation method;
Labor turnover is measured by dividing the total number of separations (workers left
the organisation) during a period by the average number of workers on the pay roll.
Labor turnover
Number of separations in a period x 100 Average number of
workers in a period
(2) Flux method:
Labor turnover is measured by dividing the total number of separations and
replacements by the average number of workers.
Labor turnover
Number of separations + number of replacement x 100 Average number
of workers during the period.
(3) Replacement method:
Labor turnover is measured by dividing the number of replacements during a
period by the average number of workers employed in that period.
Labor turnover
Number of workers replaced during the period
Average number of workers during the period.
Average workers employed = Number of workers at the beginning of the period + Number of
workers at the end of that period divided by 2.
PRACTICE QUESTION
The personnel department of a company has supplied the following information relating to its
work force during the month of June, 2006.
Number of workers:
1st. June
1900
th
30 . June
2100
During the month 60 persons were discharged and 20 left the company. During the month 200
workers were engaged out of which only 40 workers were appointed against the vacancy caused by
the number of workers separated and the remaining on account of an expansion scheme of the
company.
Calculate labor turnover rate and equivalent rate under different methods.

The working results of the above practice question reveals wide fluctuations among the different
annual labor turnover rates obtained by different methods of measurement.
The flux method of labor turnover denotes the total change in the composition of labor force.
While replacement method takes into account only workers appointed against the vacancy caused
due to discharge or quitting of the organisation. This method does not take into account the
workers employed under the expansion schemes of the company.
However, it must be noted that if a department is closed and workers retrenched, it would not be a
case of labor turnover.
The higher percentage of labor turnover, the higher will be the cost of recruitment and training of
new workers. A higher rate of labor turnover also reduces the efficiency since good deal of work
would be done by new inexperienced workers. The objective of management therefore should be
to keep the percentage of labor turnover at minimal. However, in any organisation a minimum rate
of labor turnover will always occur particularly due to retirement, marriages, death and personal
betterment.
Causes of Labor Turnover
Labor turnover arises because of various factors including dissatisfaction with job, low rate of
wages, unsatisfactory working conditions and non-availability of adequate basic amenities.
The causes of labor turnover may be sub-divided as:
(1) Avoidable causes, and
(2) Unavoidable causes.
100
Cost & Management Accounting (MGT-402)
VU
(1) Avoidable Causes:
a) These include low wages rate in the present organisation and the worker may look
for higher wages elsewhere,
b) Dissatisfaction with job,
d) Long and odd working hours,
e) Unsatisfactory relationship with the supervisors,
f) Bad relationship with the fellow workers,
g) Lack of adequate recreational facilities,
i) Unfair methods of promotion and lack of promotions avenues,
j) Lack of planning and foresight on the part of management, seasonal nature of
industry, non-availability of raw materials, power, etc.
(2) Unavoidable Causes include:--
a) Personal betterment of worker,
b) Retirement and death leading to labor turnover,
c) Domestic responsibilities--to look after old parents,
d) Accident or illness rendering workers permanently incapable to work,
e) Dismissal or discharge due to insubordination, negligence, inefficiency, etc.,
f) Marriages, specially in case of women workers,
Effect of Labor Turnover
The higher rate of labor turnover results in increased cost of production. This is due to--
(i)
Increased cost of new recruitment, training,
(ii)
Interruption of production,
(iii)
Decrease in production due to inefficiency and inexperience of
newly recruited workers,
(iv)
The new workers are more accident prone and are liable to cause
more damage to machinery, tools than old employees,
(v)
Losses due to wastage, spoilage and defectives,
(vi)
Increased number of accidents causing loss of output and increase
in medical expenses and cost of repairs,
(vii)  Lack of cooperation and coordination between old and new
employees resulting fall in output and increased cost of production,
LABOR EFFICIENCY AND UTILISATION
Labor is a significant cost in many organisations and it is important to continually measure the
efficiency of labor against pre-set targets.
Measuring labor efficiency
To measure labor efficiency: Compare actual efficiency with predetermined targets (or budgets)
using `standard hours'.
A standard hour is the number of production units which should be achieved by an experienced
worker within a period of one hour.
We can assume that all organisations will benefit from efficient labor, thus it is important to
measure how efficient workers are and identify opportunities for improvement.
The following practice question shows the calculation of the efficiency ratio.

The efficiency ratio is calculated by the following formula:
Actual output measured in standard hours Actual hours
Actual hours
840 x ½ hours (30 minutes) = 420 hours
420 x 100 = 102.44%

Factory overhead costs are those costs incurred which cannot be identified directly to cost unit.
These are incurred in many different parts of organisation.
These include:
1. Indirect materials
2. Indirect labor and
3. Indirect costs attributable to production and the service activities associated with
manufacturing.
Marketing, general administration, research and development costs that are not associated with
manufacturing are not usually treated as overheads for this purpose.
Factory overhead costs are incurred in three main centers:
·  Production centers
costs arising in production departments such as the costs of
fuel, protective clothing, depreciation and supervision.
·  Service centers
the cost of operating support departments or sections
within the factory, for example, the costs of materials handling, production control, and
canteen.
·  General costs centersgeneral production overhead such as factory rent/taxes, heating and
lighting and production management salaries.
The purpose of cost accounting is to provide information to the management. Management need
to know cost per unit as a basis for valuing inventory and for decision making.
FOH Cost Allocation & Apportionment
The total cost of factory overhead needs to be distributed among specific cost centers. Some items
102
Cost & Management Accounting (MGT-402)
VU
can be allocated immediately, e.g. the salary of a cost centre supervisor or indirect materials issued
to a cost centre. Other items need to be apportioned between a number of centers, e.g. factory rent
and taxes or the factory manager's salary.
Cost Allocation
It refers to the costs that can be identified with specific cost centers.
Apportionment
It refers to the costs that cannot be identified with specific cost centre but must be divided among
the concerned department/cost centers.
Steps of Allocation & Apportionment
1. Item wise collection of FOH cost.
2. Identifying cost centre (Production & Services).
3. Allocating and apportioning general F.O.H cost to the cost centers.
4. Apportioning FOH cost of service cost centers to the production cost centers.
5. Calculation of total FOH cost for each production cost centers.
6. Determining FOH rate for each production cost center.
FOH Absorption Rate
Finally FOH absorption rate is calculated at which the cost is absorbed in the cost unit. This is also
known as overhead absorption rate (OAR) this can be calculated as under:
OAR = Estimated F.O.H cost
Base
Bases for FOH Absorption Rate
Following can be used as base to calculate overhead absorption rate:
1. Direct Labor hours
2. Machine hours
3. No. of unit produced
4. Direct labor cost
5. Prime cost
