Complete notes for Class 11 Accountancy Chapter 1 on Introduction to Accounting. Covers all basic terms, the three types of accounts, golden rules of accounting, twelve CBSE accounting concepts and 10 worked examples — written in simple language for CBSE students.

Key Takeaways

  • Accounting records, classifies, summarises and interprets all financial transactions of a business.
  • Book-keeping is only the first step in accounting — the recording part. Accounting is much wider.
  • Three types of accounts exist: Personal, Real and Nominal. Each type has its own golden rule.
  • The Golden Rules tell you when to debit and when to credit each account in any transaction.
  • Every transaction affects two accounts equally — this is the Dual Aspect Concept and the basis of double entry.
  • The basic accounting equation is: Assets = Capital + Liabilities. It must always balance.
  • Chapter 1 covers 12 accounting concepts. Going Concern, Matching, Accrual and Conservatism are the most exam-important.

When you open your Class 11 Accountancy textbook for the first time, Chapter 1 lays out the entire foundation you will need for the rest of the year — and for Class 12 too. Almost every question in your board exam connects back to the terms, rules and concepts explained here.

This chapter covers what accounting actually is, who needs it, the terms you will use every day in journal entries, the three types of accounts, the golden rules, and the twelve accounting concepts that all accountants follow. Read this carefully once and the rest of Accountancy becomes logical, not just memorisation.

What is Accounting?

Think of a shopkeeper who sells goods every day. At the end of the month, he needs to know: How much did I sell? How much did I spend? Do I owe money to anyone? Does anyone owe money to me? How much profit did I make?

Accounting is the system that answers all these questions — for any business, big or small.

Definition (AICPA, 1941): "Accounting is an art of recording, classifying and summarising in a significant manner and in terms of money, transactions and events which are in part at least, of a financial character and interpreting the results thereof."

Breaking this definition down:

  • Recording — Writing down every financial transaction (in the Journal)
  • Classifying — Grouping similar transactions together (in the Ledger)
  • Summarising — Preparing the Trial Balance and Final Accounts
  • In terms of money — Only transactions that can be measured in money are recorded
  • Interpreting — Explaining what the numbers mean to the people who need them

Fig 1 — The six steps of the accounting process. Accounting is much more than just recording.

Origin of Accounting

Accounting has existed for thousands of years — ancient civilisations in Egypt and Mesopotamia kept records of grain and cattle. But the formal double entry system we use today was documented by an Italian mathematician, Fra Luca Pacioli, in 1494 in his book Summa de Arithmetica, Geometria, Proportioni et Proportionalita.

Pacioli described the method of recording every transaction with two equal effects — a debit and a credit. This principle, developed over 500 years ago, is still the foundation of modern accounting.

Book-keeping vs Accounting

Students often confuse these two terms. Here is the key difference: book-keeping is a part of accounting — specifically, the recording part. Accounting is the complete process.

Book-keeping • Identifies financial transactions • Measures transactions in money • Records in books of accounts • Clerical in nature • Done by a book-keeper No analysis or interpretation Accounting • Includes all of book-keeping • Classifies and summarises data • Prepares financial statements • Analyses and interprets results • Communicates to stakeholders Analytical and management-oriented

Objectives of Accounting

Why does a business need accounting? Here are the main objectives:

  1. Systematic recording — Every rupee that comes in or goes out is written down in an organised way, reducing the chance of forgetting or losing information.
  2. Finding profit or loss — At the end of a period, accounting tells you whether the business made a profit or suffered a loss.
  3. Knowing financial position — The Balance Sheet shows exactly what the business owns (assets) and what it owes (liabilities) on a particular date.
  4. Helping management — Managers use accounting data to plan budgets, control costs, and make business decisions.
  5. Legal compliance — Businesses are required by law to maintain proper accounts for tax assessment, audit and regulatory filing.
  6. Preventing fraud — Proper accounting with records and checks makes it harder for anyone to misuse money without it being detected.

Users of Accounting Information

Accounting information is used by many different people, not just the owner. They are divided into two groups: internal users (inside the business) and external users (outside the business).

Accounting Information Owner / ShareholdersCheck profitability ManagementPlan & control EmployeesJob security & wages INTERNAL USERS Banks & LendersCreditworthiness InvestorsInvestment decisions GovernmentTax & regulation EXTERNAL USERS
Fig 3 — Internal and external users of accounting information and what each group looks for.
UserTypeWhat They Need to Know
Owner / ShareholdersInternalIs the business profitable? What are my returns?
ManagementInternalWhere can we cut costs? How do we grow?
EmployeesInternalIs the business stable? Can I get a raise?
Banks and LendersExternalCan the business repay its loan?
InvestorsExternalShould I invest here? Will I get good returns?
Government (Tax Dept.)ExternalHow much tax does the business owe?
Creditors / SuppliersExternalWill the business pay its bills on time?
CustomersExternalWill this supplier be around long-term?

Branches of Accounting

Accounting has grown into several specialised branches, each serving a specific purpose:

Financial Accounting

Records day-to-day transactions and prepares final accounts — Trading Account, Profit & Loss Account and Balance Sheet. Used by external stakeholders.

Cost Accounting

Calculates the cost of manufacturing a product or providing a service. Helps management price products correctly and control production costs.

Management Accounting

Provides financial and non-financial information to management for planning, budgeting, performance evaluation and strategic decisions.

Basic Accounting Terms — 15 Terms You Must Know

These terms appear repeatedly in every chapter. Learn them once and they will stay with you for all of Class 11 and 12.

15InvoiceA bill sent by the seller to the buyer listing goods sold and amount dueA seller sends an invoice of ₹15,000 to the buyer

Types of Accounts

Every account in accounting falls into one of three categories. Knowing the type of an account tells you which golden rule to apply.

Personal Account Accounts of persons Natural Person Ramesh A/c, Suresh A/c Artificial Person SBI A/c, Tata Ltd A/c Representative Prepaid Expense A/c Real Account Accounts of assets Tangible Assets Cash A/c, Land A/c Machinery, Furniture Intangible Assets Goodwill A/c Patents A/c, Copyright Nominal Account Income & Expense A/cs Expenses Salary A/c, Rent A/c Electricity A/c Incomes Commission A/c Interest Received A/c
Fig 4 — Three types of accounts with sub-categories and examples.
Account TypeWhat it RecordsSub-typesExamples
PersonalPersons, firms, institutionsNatural, Artificial, RepresentativeRamesh A/c, SBI A/c, Prepaid Rent A/c
RealAssets owned by the businessTangible, IntangibleCash A/c, Goodwill A/c, Machinery A/c
NominalIncomes, expenses, gains, lossesSalary A/c, Sales A/c, Discount A/c

Important: Nominal accounts are temporary — they are opened at the start of each year and closed at the end, with balances transferred to the Profit & Loss Account. Personal and Real accounts are permanent — their balances carry forward to the next year.

Golden Rules of Accounting

The golden rules tell you which account to debit and which to credit in every transaction. There is one rule for each type of account. Memorise these three rules and you can pass any journal entry question.

GOLDEN RULES OF ACCOUNTING Account Type Debit (Dr.) Credit (Cr.) Personal Account Accounts of persons/firms Debit the Receiver Credit the Giver Real Account Accounts of assets Debit what Comes In Credit what Goes Out Nominal Account Accounts of incomes/expenses Debit all Expenses & Losses Credit all Incomes & Gains
Fig 5 — The three golden rules of accounting. Apply the correct rule based on the account type.

Here is how to use the golden rules in practice. Every transaction involves two accounts. Identify each account's type, then apply the appropriate golden rule to know whether to debit or credit it.

Example: Paid salary ₹20,000 in cash.
→ Salary Account = Nominal (expense) → Debit all expenses
→ Cash Account = Real (asset going out) → Credit what goes out
Entry: Salary A/c Dr. ₹20,000 / To Cash A/c ₹20,000

Accounting Concepts and Conventions

Accounting concepts are rules and assumptions that all accountants follow to make sure financial statements are prepared consistently and honestly. CBSE Chapter 1 covers the following twelve concepts.

12 Accounting Concepts — CBSE Class 11 Business Entity Money Measurement Going Concern Cost Concept Dual Aspect Accounting Period Matching Realisation Accrual Consistency Conservatism / Prudence Materiality
Fig 6 — Twelve accounting concepts covered in CBSE Class 11 Chapter 1.
ConceptWhat it MeansStudent Example
Business EntityThe business is separate from its owner. Owner's personal expenses are never recorded in business books.Owner pays house rent — not recorded in business accounts.
Money MeasurementOnly transactions measurable in money are recorded. Non-monetary events (like employee morale) are excluded.A talented employee is an asset but is not recorded in accounts.
Going ConcernBusiness is assumed to continue indefinitely. Assets are valued at cost, not sale value.Machinery worth ₹5 lakh is shown at ₹5 lakh (minus depreciation), not resale value.
Cost ConceptAssets are recorded at their purchase cost (historical cost), not current market value.Land bought for ₹10 lakh in 2010 is still shown at ₹10 lakh, even if worth ₹50 lakh today.
Dual AspectEvery transaction has two effects — one debit and one credit of equal amounts.Buy goods for ₹5,000 cash: Purchases Dr. ₹5,000 / Cash Cr. ₹5,000.
Accounting PeriodBusiness life is divided into regular time periods (usually one year) to measure performance.Financial year in India: 1 April to 31 March.
MatchingExpenses of a period must be matched with the revenues of the same period.Salary for March is recorded in March, even if paid in April.
RealisationRevenue is recognised only when it is earned (goods delivered or service provided), not when cash is received.Order received in March but goods delivered in April — revenue recorded in April.
AccrualTransactions are recorded when they occur, not when cash is received or paid.Electricity used in March but bill paid in April — recorded as expense in March.
ConsistencyAccounting methods should remain the same from year to year for fair comparison.If Straight Line Method for depreciation is used in Year 1, continue in Year 2.
ConservatismAnticipate losses and provide for them; do not anticipate profits until they are actually earned.Stock is valued at cost or market value, whichever is lower.
MaterialityOnly significant items need strict accounting treatment. Trivial items can be handled simply.A ₹10 pen is expensed immediately rather than being depreciated over years.

10 Worked Examples — Applying the Golden Rules

Let us apply the three golden rules to real transactions. For each example, identify the two accounts involved, their type, and the rule to apply.

  1. Started business with cash ₹1,00,000.
    Cash A/c (Real) — comes in → Debit ₹1,00,000
    Capital A/c (Personal) — giver → Credit ₹1,00,000

  2. Bought furniture for cash ₹20,000.
    Furniture A/c (Real) — comes in → Debit ₹20,000
    Cash A/c (Real) — goes out → Credit ₹20,000

  3. Purchased goods from Mohan on credit ₹15,000.
    Purchases A/c (Nominal — expense) → Debit ₹15,000
    Mohan's A/c (Personal — giver) → Credit ₹15,000

  4. Sold goods to Seema for cash ₹25,000.
    Cash A/c (Real) — comes in → Debit ₹25,000
    Sales A/c (Nominal — income) → Credit ₹25,000

  5. Paid rent ₹5,000 in cash.
    Rent A/c (Nominal — expense) → Debit ₹5,000
    Cash A/c (Real) — goes out → Credit ₹5,000

  6. Received commission ₹3,000 in cash.
    Cash A/c (Real) — comes in → Debit ₹3,000
    Commission Received A/c (Nominal — income) → Credit ₹3,000

  7. Paid salary ₹12,000 in cash.
    Salary A/c (Nominal — expense) → Debit ₹12,000
    Cash A/c (Real) — goes out → Credit ₹12,000

  8. Deposited cash ₹30,000 into bank.
    Bank A/c (Personal — receiver) → Debit ₹30,000
    Cash A/c (Real) — goes out → Credit ₹30,000

  9. Owner withdrew ₹8,000 for personal use.
    Drawings A/c (Personal — receiver) → Debit ₹8,000
    Cash A/c (Real) — goes out → Credit ₹8,000

  10. Paid Mohan ₹15,000 in full settlement.
    Mohan's A/c (Personal — receiver, as the debt is cleared) → Debit ₹15,000
    Cash A/c (Real) — goes out → Credit ₹15,000

Important Points to Remember

  • Accounting deals only with transactions measurable in money (Money Measurement Concept).
  • The business and its owner are treated as separate entities (Business Entity Concept).
  • Every transaction has exactly two effects — one debit and one credit of equal value (Dual Aspect).
  • The three types of accounts are Personal, Real and Nominal — each with its own golden rule.
  • Cash Account and all asset accounts are Real Accounts — use "Debit what comes in, Credit what goes out."
  • Nominal accounts are temporary — they close at the end of each year and their balances go to P&L Account.
  • Personal and Real accounts are permanent — their balances carry forward to the next year.
  • Assets = Capital + Liabilities — this equation must always balance.
  • Revenue is recognised when earned, not when cash is received (Realisation + Accrual Concepts).
  • Losses are anticipated and provided for; profits are recorded only when earned (Conservatism Concept).
  • Assets are recorded at cost price, not market value (Cost Concept).
  • The Indian financial year runs from 1 April to 31 March (Accounting Period Concept).

Common Mistakes Students Make

  • Confusing book-keeping with accounting. Book-keeping is just recording. Accounting includes recording, classifying, summarising AND interpreting. In exams, these are different definitions.
  • Applying the wrong golden rule. Always identify the account type first (Personal / Real / Nominal), then apply the rule. Many students apply the Nominal rule to Real accounts and vice versa.
  • Treating Cash Account as Personal. Cash Account is a Real Account, not Personal. The golden rule for Cash is "Debit what comes in, Credit what goes out."
  • Confusing Debtors and Creditors. Debtors owe money to us (asset). Creditors — we owe money to them (liability). Remember: Debtor = D for "Due to us."
  • Mixing up Drawings and Expenses. Drawings are money withdrawn by the owner for personal use — it is not a business expense. It reduces Capital.
  • Writing wrong concept for a scenario. In theory questions, students often write "Going Concern" when the correct answer is "Cost Concept" or vice versa. Study the definition of each concept carefully.
  • Forgetting the Business Entity Concept. Owner's personal transactions are never recorded in business books. Many students include the owner's home rent in business expenses — this is wrong.

Exam Tips for Chapter 1

  • 1-mark questions typically ask for a definition or to identify the account type. Write the definition in one clear sentence.
  • 3-mark questions may ask to distinguish between two terms (like book-keeping vs accounting) or explain a concept with an example.
  • Concept questions: Every concept needs a definition AND an example. Never write a concept answer without an example — you lose marks.
  • Golden rules: These appear in journal entry questions. If you know all three rules perfectly, journal entries become straightforward mechanical work.
  • Users of accounting: The examiner may ask you to list internal users OR external users — not both. Read the question carefully.
  • Most important concepts for exams: Business Entity, Going Concern, Cost Concept, Dual Aspect, Matching, Accrual and Conservatism.

Frequently Asked Questions

What is the definition of accounting according to AICPA?+
According to the American Institute of Certified Public Accountants (AICPA, 1941): "Accounting is an art of recording, classifying and summarising in a significant manner and in terms of money, transactions and events which are in part at least, of a financial character and interpreting the results thereof."
What is the difference between book-keeping and accounting?+
Book-keeping is only the recording step — it involves identifying and entering financial transactions in books of accounts. Accounting is wider and includes book-keeping plus classifying, summarising, analysing, interpreting and communicating financial information. A book-keeper records; an accountant analyses and helps management make decisions.
What are the three types of accounts in accounting?+
There are three types: (1) Personal Accounts — accounts of persons, firms or institutions such as Ramesh's Account or Bank Account. (2) Real Accounts — accounts of assets, both tangible (Cash, Machinery) and intangible (Goodwill, Patents). (3) Nominal Accounts — accounts of incomes, expenses, profits and losses such as Salary Account, Rent Account, Commission Received Account.
What are the golden rules of accounting for all three types of accounts?+
The three golden rules are: (1) Personal Account — Debit the receiver, Credit the giver. (2) Real Account — Debit what comes in, Credit what goes out. (3) Nominal Account — Debit all expenses and losses, Credit all incomes and gains. These rules guide every journal entry in double entry book-keeping.
What is the dual aspect concept in accounting?+
The dual aspect concept states that every financial transaction has two equal and opposite effects. One account is debited and another is credited by the same amount. This forms the foundation of double entry book-keeping. The basic accounting equation — Assets = Capital + Liabilities — always stays balanced because of this concept.
Who are the internal users of accounting information?+
Internal users are people inside the business who use accounting information for management and decisions. They include: (1) Owners or shareholders — to check profitability and returns, (2) Management — to plan, budget and control operations, and (3) Employees — to assess job security and salary prospects.
Who are the external users of accounting information?+
External users are outside the organisation. They include: (1) Banks and lenders — to check creditworthiness before giving loans, (2) Investors — to decide whether to invest or withdraw funds, (3) Government — for tax assessment and regulation, (4) Creditors — to check if the business can pay its debts on time, and (5) Customers — to assess the long-term stability of their supplier.
What is the going concern concept in Class 11 Accountancy?+
The going concern concept assumes that a business will continue to operate indefinitely and does not plan to shut down in the near future. Because of this, assets are recorded at historical cost (minus depreciation) rather than their immediate sale value. For example, a machine bought for ₹5,00,000 is shown at cost less depreciation, not at the price it would fetch if sold today.
What is the difference between debit and credit in accounting?+
Debit means the left side of an account (abbreviated Dr.) and Credit means the right side (Cr.). For asset and expense accounts, an increase is recorded as a debit. For liability, capital and income accounts, an increase is recorded as a credit. The golden rules of accounting determine which account is debited and which is credited for each type of transaction.
What is capital in accounting and how is it calculated?+
Capital is the amount invested by the owner in the business. It is also called Owner's Equity. Capital = Assets − Liabilities. If a business has total assets of ₹15,00,000 and total liabilities of ₹5,00,000, then Capital = ₹10,00,000. Capital increases with profits or fresh investment and decreases when the owner withdraws money (drawings) or when the business makes a loss.
What is the difference between assets and liabilities?+
Assets are resources owned or controlled by a business that provide future economic benefit — examples include cash, land, machinery, stock, and debtors. Liabilities are amounts owed to outsiders — examples include bank loans, creditors and outstanding expenses. The fundamental accounting equation is: Assets = Capital + Liabilities.
What are the objectives of accounting?+
The main objectives of accounting are: (1) Systematic recording of all financial transactions to avoid errors, (2) Determining profit or loss for a period, (3) Knowing the financial position — what the business owns and owes, (4) Providing decision-making information to management, and (5) Ensuring legal compliance for tax, audit and regulatory requirements.
What are the three branches of accounting?+
The three main branches are: (1) Financial Accounting — records day-to-day transactions and prepares final accounts including Trading Account, Profit & Loss Account and Balance Sheet. (2) Cost Accounting — determines the cost of producing goods or services to help set prices. (3) Management Accounting — provides financial data to managers for planning, budgeting and performance evaluation.
What is a nominal account and what is its golden rule?+
A nominal account records incomes, revenues, expenses and losses of a business. Examples: Salary Account, Rent Paid Account, Commission Received Account, Discount Allowed Account. The golden rule is: Debit all expenses and losses; Credit all incomes and gains. Nominal accounts are closed at the end of each accounting period — their balances transfer to the Profit & Loss Account.
What is the matching concept in accounting?+
The matching concept states that expenses must be recognised in the same accounting period as the revenues they helped generate, regardless of when cash is paid or received. For example, if goods are sold in March but payment is received in April, the revenue is recorded in March. The expenses for earning that revenue are also matched to March. This gives a true picture of profit for the period.
