COST CLASSIFICATION
Costs may be classified under three main categories:
- Fixed and variable costs
- Direct and indirect costs
- Cost classification by function
FIXED AND VARIABLE COST
Fixed Cost
Fixed cost is the cost that remains the same at various levels of output. This cost does not change with changes in output; it remains constant even at zero level of output.
Fixed costs are usually incurred on a periodic basis.
Examples include rent of premises and salaries of permanent employees.
Variable Cost
Variable cost is the cost that changes with the level of production or output.
When production increases, variable cost also increases proportionally.
Examples of variable costs include raw materials, direct wages, and other related costs.
DIRECT AND INDIRECT COST
Direct Cost
Direct cost is the cost that can be identified with the production of specific products. Examples include raw materials and labor costs. Since these costs can be charged and identified to the production of specific outputs, they are considered direct costs.
These costs are directly associated with the production of goods or outputs.
Indirect Cost
Indirect cost is the cost that cannot be identified with the production of specific products or outputs. Examples include water charges, interest rates, indirect materials, and communication charges.
Cost Classification by Function
Costs may also be classified by their functions or activities, such as production cost, administration cost, and selling and distribution cost.
- Production cost includes raw materials, labor, rent of factories, etc.
- Administration cost involves office expenses such as office rent, postage, telephone, electricity, etc.
- Selling and distribution cost includes costs incurred to promote the selling of goods and deliver them to customers, such as advertisement, salesmen commission, depreciation of delivery vans, carriage outward, and carriage inward.
ANALYSIS OF COST
The total cost incurred by a manufacturing firm may be analyzed by the cost accountant as follows:
- Direct raw materials (D.R.M) xx
- Direct labor/Direct wages xx
- Direct any other cost xx
Total direct cost = prime cost xx
Add:
Production overhead (manufacturing overhead)
- Indirect wages xx
- Indirect factory wages xx
Manufacturing/production cost xxx
In case of profit or loss:

BREAK EVEN POINT (B.E.P)
The break-even point is the level of activity at which total sales revenue equals total cost (TR = TC). At this point, profit is zero, meaning there is no profit and no loss.
ASSUMPTIONS OF B.E.P CHART
The following assumptions apply to the break-even chart:
- Selling price and variable cost per unit remain constant at various levels of output.
- Fixed cost remains constant at all levels of activity within the relevant range.
- The chart shows the relationship between cost and sales of a single product only.
- Production techniques remain unchanged.
ILLUSTRATION
You are required to prepare from the following information:
- A break-even chart
- A contribution/sales graph or profit volume graph
- Show the margin of safety on this chart if the actual level of output is 20,000 units
Selling price per unit is 100/=
Variable cost per unit is 50/=
Fixed cost is 600,000/=
BREAK EVEN CHART
| LEVEL OF OUTPUT PER UNIT | FIXED COST | VARIABLE COST Tshs 50 per unit | TOTAL COST | SALES Tshs 100 per unit | PROFIT & LOSS |
|---|---|---|---|---|---|
| 5,000 | 600,000 | 250,000 | 850,000 | 500,000 | -350,000 |
| 10,000 | 600,000 | 500,000 | 1,100,000 | 1,000,000 | -100,000 |
| 15,000 | 600,000 | 750,000 | 1,350,000 | 1,500,000 | 150,000 |
| 20,000 | 600,000 | 1,000,000 | 1,600,000 | 2,000,000 | 400,000 |
MARGIN OF SAFETY
Margin of safety represents the difference between the actual level of activity and the break-even level of activity.
- For example, if the actual level of activity is 80% and the break-even level is 30%, calculate the margin of safety.
= Margin of safety = Actual sales – B.E.P sales
= Margin of safety = 80% – 30%
Margin of safety = 50%
ANGLE OF INCIDENCE
The angle of incidence is the angle formed at the break-even point between the sales curve and the total cost curve.
- This angle indicates the rate of increase in profit after the break-even point.
- If this angle is wider, profit will increase at a higher rate after the break-even point.
CALCULATION OF BREAK EVEN POINT
ILLUSTRATION 1
State the formula to calculate the break-even point in terms of units to be produced and sold.
We use the following abbreviations:
- S.P = Selling price
- C.P = Cost price
- P = Profit
- C.M = Contribution margin; contribution margin per unit = CM/U
S.P = C.P + P
C.P = F.C + V.C
Contribution margin = S.P – V.C
B.E.P in terms of units produced = (F.C) / (Contribution margin per unit)
B.E.P in terms of sales value = (F.C) / (CM/C) × (S.P)/U
Contribution margin per unit = (S.P)/U – (V.C)/U
Sometimes variable cost = material + labour
Contribution margin ratio = (C.M) / (S.P) or (F.C) / (1 – V.C / S.P)
ILLUSTRATION 2
Star manufactures a product called plate in his own factory. Fixed cost per month is 45,000. Each unit of plate costs 8/= for material and 17/= for direct labor. The selling price per unit is 40/=. How many units must he manufacture and sell per month to break even?
SOLUTION
GIVEN DATA
- Fixed cost = 45,000
- Selling price/unit = 40/=
- Unit cost of plate by material = 8/=
- Unit cost of plate by direct labor = 17/=
- Contribution margin = selling price – variable cost
- Variable cost = material + labor = 8 + 17 = 25
- Contribution margin = 40 – 25 = 15
STATEMENT OF PROFIT / LOSS
| Sales (3000 x 40/=) | 120,000 | |
| Less; variable cost | ||
| Unit cost of plate by material (8 x 3000) | 24,000 | |
| Unit cost of plate by direct labor (17 x 3000) | 51,000 | |
| Fixed cost | 45,000 | |
| (120,000) | ||
| B.E.P (Break Even Point) | 0 |
The above presentation verifies that sales of 120,000 result in zero profit.

Assuming the company wishes to make a profit of 6,000 per month, calculate the number of units that must be produced and sold to attain this profit. Also calculate the sales revenue required to generate this profit.
Solution
(Fixed cost + desired profit) / (contribution margin per unit)
Sales revenue = Quantity to be produced × SP/U
- DM/U = 8
- DL/U = 17
- F.C = 45,000
- Desired profit = 6,000
- Contribution margin = 15
- SP/U = 40/=
Quantity to be produced = (F.C + Desired profit) / CM/U = (45,000 + 6,000) / 15 = 3,400 units
Sales revenue = 3,400 × 40 = 136,000

P.LTD manufactures a standard product called Pipi. The following is a summary of their costs incurred in 2008:
- Fixed factory cost 24,000
- Fixed administration cost 10,800
- Direct labour 48,000
- Depreciation of plant (variable cost) 8,000
- In 2008, a total of 40,000 units of Pipi were produced/manufactured at a standard price of £5.20 per unit.
- The company has been approached by a manufacturer to supply annually 5,000 units of Pipi at £4.50 per unit. Currently, the whole of P.LTD’s plant capacity is being used, so to produce the additional 5,000 units, the company will need to acquire plants at a cost of £20,000 with a useful life of 10 years and no residual value. Additional production will also increase factory cost by 5% and selling distribution cost by 10%.

CASH BUDGET
CONCEPT
BUDGET
A budget is a plan of action expressed in quantitative terms or a financial and quantitative statement prepared and approved prior to a defined period of time. It may include income, expenditure, and the employment of capital.
Budgets may be prepared for the business as a whole, for departments, or for functions such as:
- Sales and production
- Financial and resource items such as cash, capital, expenditures, purchases, manpower, etc.
Examples of budgets include:
- Sales budget
- Production budget
- Purchases budget
- Production cost budget
- Selling and distribution cost budget
- Cash budget
- Budgeted profit and loss account and balance sheet
Benefits of Budget
- Budgets provide a compiled plan; with budgets, a firm has clear guidelines and financial and human resources can be utilized to achieve specific targets or objectives.
- Budgets help improve communication and coordination among management and employees.
- Budgets are used to determine and evaluate the performance of the business enterprise.
- Budgets help clarify the authority and responsibility of departmental managers and other staff members.
CASH BUDGET
What is it?
A cash budget is prepared to show the expected cash receipts and payments over the next few months or a one-year period.
The main functions of a cash budget are to:
- Ensure that cash is available for revenue expenditure.
- Indicate when, where, and how much cash will be needed and whether this is permanent or temporary.
- Preserve liquidity throughout the year.
- Reveal surplus cash for investment or expansion of facilities.
- Guide management on financing capital expenditure internally or externally. capital
The cash budget is affected by the following:

COMPUTERIZED ACCOUNTING
The word computer comes from the word “compute,” which means to calculate.
- The initial objective of inventing the computer was to create a fast calculating machine.
- Nowadays, more than 80% of work done by computers is non-mathematical in nature. In reality, a computer may be defined as a device that processes information or data. Data can be of various types, such as when a computer is used for recruiting personnel or preparing results.
- Data may come in various shapes and sizes depending on the type of computer application. A computer can store, process, and retrieve data as and when desired. For this reason, computers are also known as data processors. Data processors can gather data from various incoming sources, merge (process) them, sort them in desired order, and print them in the desired format.
FEATURES OF A COMPUTER
HIGH SPEED OF OPERATION
The special feature of a computer is its high speed. Computers work at electronic speeds measurable in millionths of a second. A computer can make millions of calculations without errors within a few minutes.
ECONOMY
Every effort should be made to keep costs to a minimum level. The use of computers saves money for users and ensures production of quality goods at the least possible cost.
DILIGENCE
Computers are particularly desirable for repetitive work because they provide correct information continuously, whereas humans are bound to make more errors as they get tired.
STORAGE OF DATA
A computer has memory like human beings. Unlike human memory, computers have very large and accurate memory. The storage unit in the computer is called memory. It can recall any bit of information stored as and when needed without much loss of time.
DECISION MAKING
Computers can make decisions based on pre-defined criteria and can solve problems in different fields. A computer can take logical decisions and perform any job that can be split into logical decisions.
ENSURES FLEXIBILITY
A computer can modify stored programs if desired, ensuring flexibility.
CONTROL
A mechanized system with the help of a computer provides up-to-date information to management, enabling sound managerial decisions.
SCIENTIFIC RESEARCH
Computers have greatly aided scientific research by processing large volumes of data quickly and accurately.
COMPONENTS OF COMPUTER
The basic components of a computer are:
- Input unit
- Memory or storage unit
- Arithmetic and logic unit
- Output unit
- Control unit
BASIC ORGANIZATION OF COMPUTER SYSTEM
The various functions performed by each unit are as follows:
INPUT UNIT
This unit transfers information from outside to the memory or storage unit by methods such as:
- Punched cards passed through a punched card reader
- Punched paper tape passed through a punched card reader
- Magnetic tape or disc passed through a magnetic tape or disc reader
- Magnetic tape works like a domestic tape recorder with two reels and a mechanism for reading and writing data. Data recorded on the tape may be retained permanently or erased by recording other data over it. Data can be inserted after punching, which is not possible with punched cards or paper tape.
MEMORY OR STORAGE UNIT
This unit stores figures and releases them at electronic speed for calculations. It retains temporary results of sub-calculations and final results before passing them to the output unit. The cost and size of a computer depend on its internal storage capacity.
ARITHMETIC AND LOGIC UNIT
Required calculations and logical operations are done in this unit by taking necessary information from the memory unit. It performs addition, subtraction, multiplication, and division at high speed. The logic unit makes decisions based on instructions requiring yes/no answers.
OUTPUT UNIT
This unit produces the end product, such as reports or final information, and transfers it to outside documents like printed papers, punched cards, or magnetic tape.
CONTROL UNIT
Also called the program controller, it supervises each unit of the computer. Once data is fed into the input unit, the control unit manages the data as instructed by the computer program.
The main component of the computer is the CENTRAL PROCESSING UNIT (CPU), which contains:
- Control unit
- Arithmetic and logic unit
HARDWARE
Hardware is the physical computer itself, including the machine, keyboard, mouse, printer, and related equipment used in electronic data processing.
SOFTWARE
Software includes all materials used in selecting, installing, and operating the electronic data processing system (except personnel). Software includes computer programs (instructions) and everything that helps the computer and its equipment perform their functions. Software is integral to hardware; one cannot function without the other.
DATA PROCESSING
Data refers to figures or statistics about any phenomenon. In accounting, data are usually expressed in monetary units. Data may also include non-monetary units such as quantities produced, number of workers, etc. Raw data are inputs that, after processing, become useful information.
DEVELOPMENT IN COMPUTERIZED ACCOUNTING
The use of computers in commercial applications has revolutionized the industrial environment. Most businesses, except the very smallest, now use computers to handle accounting data.
ADVANTAGES OF COMPUTERIZED ACCOUNTING SYSTEM
- Elimination of substantial manual work involved in posting entries.
- Quick availability of information regarding debtors, creditors, funds position, etc.
- Saving of substantial time in updating books of accounts.
- Easy availability of information as per statutory or other requirements.
- Saving storage space required for voluminous data.
- Easy preparation of final accounts and reconciliation.
- Reduction in operational costs by automating clerical work.
ACCOUNTING PACKAGING AND SOFTWARE
Software packages are sets of pre-designed programs since basic commercial activities remain the same. Some commonly used are:
I. PERSONAL COMPUTER
- a) Spreadsheet
- b) Database
- c) Word processor
(A) Spreadsheet
A software designed to facilitate creation and revision of mathematical models, analysis, and reports, usually for business applications. It is a computerized matrix or grid made up of 254 rows and 63 columns. Any item may be changed at any time and results are updated automatically. It can be used to seek goals such as specific profit figures.
Benefits of Spreadsheet
- Saves time by performing calculations across rows and columns within seconds.
- Simple tool to learn.
- Provides flexibility for playing with numbers.
- Eliminates recalculations by automatically modifying the spreadsheet for changes.
(B) Database
An organized collection of information. A computer program or group of programs that organize, store, retrieve, and allow entry and updating of data is called a Database Management System. It allows multiple users to access organized information for multiple uses. Examples include payroll and mailing lists.
(C) Word Processor
Tools designed to simplify writing tasks. It is powerful for:
- Document presentation
- Formatting documents
- Saving edited versions
A word processor combines computer hardware and software, benefiting users by eliminating the need to retype entire pages and allowing major changes without retyping.
(B) SOFTWARE PACKAGES FOR ACCOUNTING
There are many ready-made software packages available. Accounting applications are standard, so packages provide similar features. Areas covered include:
- General ledger
- Accounts payable
- Accounts receivable
(I) General ledger
Helps manage financial accounting, serving operational, statutory, and management information needs. Reports include day books, journals, and subsidiary ledgers.
(II) Accounts Payable
Monitors supplier bills, payments, and outstanding amounts. Reports include bill register, payment register, credit/debit notes, and list of outstanding.
Packages can be used as-is or modified per user requirements. Standard packages facilitate computerization of commercial applications such as trial balance, balance sheet, profit and loss statement, budget variance, funds flow statement, and ratio analysis.
(III) Accounts Receivable
Helps reduce money collection periods and minimize bad debts. Details customer invoices, receipts, and outstanding balances. Reports include invoice register, receipts register, credit/debit notes register, customer journal, customer ledger, customer statements, receipts due, interest receivable on overdue invoices, ageing reports, and customer directory.
AUDITING
Meaning of Auditing
An audit is an examination by an auditor of the final accounts (trading account, profit and loss account, and balance sheet) of a business enterprise. It involves checking supporting documents from which these accounts are prepared. The main purpose is to ascertain whether these accounts present a true and fair view of the financial position of the business.
IAG3 defines audit as an independent examination of an expression of opinion on the financial statements of an entity by an appointed auditor in pursuance of that appointment and in compliance with relevant statutory provisions including Tanzania Statements of Standard Accounting Practice (TSSAPs) and auditing standards.
Auditor: The word auditor comes from Latin ‘Audire’ meaning to hear. An auditor is an independent person appointed by business enterprises to audit its accounts. The auditor may be an individual or a firm.
The auditor’s duty is to form an opinion and report on the financial statements of a business enterprise for a specific period.
Auditing is the process of examination of financial statements covering transactions over a period to enable the auditor to issue a report.
It means auditing is the application of auditing principles.
TYPES OF AUDITING
The following are types of auditing:

AUDITOR’S WORKING PAPER
Nature and Definition
Introduction: The efficiency of audit work is enhanced through careful compilation and maintenance of audit work documentation, done through preparation of audit working papers.
Meaning: Working papers are records kept by auditors of procedures applied, tests performed, evidence gathered, and conclusions reached during the audit.
Audit working papers should be prepared as the audit proceeds to avoid omission of details and problems.
Each working paper should be properly identified with client’s name, period covered, description of contents, preparer’s initials, date, and index code.
FORMS/TYPES OF AUDITOR’S WORKING PAPER
Audit working papers are classified into two categories, each assembled in a separate file:
- Permanent Audit file for the same client
- Current Audit file
A. PERMANENT AUDIT FILE
Essential for continuous audits, valuable for successive audits. Acts as a constant reference source, avoiding repeated questions. Typically contains:
- Memoranda and Articles of association and other statutory/legal regulations
- Copies of important agreements (leases, debenture deeds, contracts)
- Brief description of business type
- Details of physical locations (factories, offices, shops)
- Details of accounting system and internal audit procedures
- Organization chart of client’s staff
- Names and addresses of client’s advisers (bankers, brokers, management)
- Lists of accounting records and responsible officials
Permanent audit files should be updated appropriately.
B. CURRENT AUDIT FILE
Holds all working papers applicable to the year under audit. Should contain:
- Authenticated copy of statement on which auditor’s report is based

Matters not of permanent importance but requiring attention should be listed with references and transferred to the next current file.
AUDIT REPORT AND OPINION
Audit report: Prepared by an independent auditor after examining financial statements, including auditor’s opinion on true and fair view.
Audit opinion: View given as a recommendation by auditor after auditing financial statements.
TYPES OF AUDIT OPINION
- Unqualified opinion: Given when auditor is satisfied that financial statements show true and fair view and comply with international accounting standards.
