CUET UG Business Studies Accounting Accounting Concepts and Conventions Double Entry System

Must-Know (15–20 detailed bullets)

• The double entry system is based on the principle that every transaction has two aspects: debit and credit. For example, if ₹10,000 cash is deposited into the bank, cash (asset) decreases and bank (asset) increases.

• In double entry accounting, the total of all debits must equal the total of all credits in the ledger. This ensures the accounting equation (Assets = Liabilities + Capital) remains balanced.

• Personal accounts follow the rule: “Debit the receiver, credit the giver.” Example: ₹5,000 paid to supplier Mr. Raj → Debit Mr. Raj A/c, Credit Cash A/c.

• Real accounts follow the rule: “Debit what comes in, credit what goes out.” Example: Furniture bought for ₹20,000 in cash → Debit Furniture A/c, Credit Cash A/c.

• Nominal accounts follow the rule: “Debit all expenses and losses, credit all incomes and gains.” Example: ₹3,000 rent paid → Debit Rent A/c, Credit Cash A/c.

• The accounting equation is: Assets = Liabilities + Capital. If assets are ₹1,50,000 and liabilities ₹60,000, capital is ₹90,000.

• Capital is treated as a liability of the business to the owner under the Business Entity Concept. Thus, it appears on the liabilities side of the Balance Sheet.

• The Going Concern Concept assumes that a business will continue to operate indefinitely and will not be liquidated in the near future. This justifies depreciation and prepaid expenses.

• The Cost Concept requires assets to be recorded at their original purchase cost, not market value. A building bought for ₹50 lakh in 2020 is recorded at ₹50 lakh even if market value is ₹80 lakh in 2023.

• The Matching Concept requires that expenses be recorded in the same period as the revenues they help generate. Example: Salary for January 2024 paid in February 2024 is recorded in January 2024.

• The Revenue Recognition (Realisation) Concept states that revenue is recorded when it is earned, not when cash is received. Sale on credit on 28 March is recorded as revenue on that date.

• The Consistency Concept requires that accounting policies be applied uniformly from one period to another. Changing depreciation method every year violates this.

• The Conservatism (Prudence) Concept means anticipate no profit but provide for all possible losses. Example: Creating provision for doubtful debts.

• The Dual Aspect Concept is the foundation of double entry system: every transaction affects at least two accounts. Example: ₹15,000 loan taken from bank → Debit Cash A/c, Credit Bank Loan A/c.

• The Money Measurement Concept states only transactions measurable in monetary terms are recorded. Employee skill or brand image not recorded.

• The Accounting Period Concept divides the life of a business into intervals (usually 12 months) for performance measurement. Financial year in India ends on 31 March.

• The Full Disclosure Concept requires all material information to be disclosed in financial statements. Example: contingent liabilities in notes.

• The Materiality Concept allows small items (e.g., ₹50 eraser) to be written off as expense even if long-life, due to insignificance.

• A transaction like purchasing goods for ₹10,000 on credit affects two accounts: Purchases A/c (debit) and Creditor A/c (credit).

• Withdrawal of ₹5,000 by owner for personal use: Debit Drawings A/c, Credit Cash A/c — reduces capital but not treated as business expense.

Difficulty Level

Intermediate — Requires understanding of conceptual application and transaction analysis, not just memorization.

A. Going Concern Concept
B. Matching Concept
C. Cost Concept
D. Business Entity Concept

Answer: A
Explanation: The Going Concern Concept allows for allocation of expenses over future periods, justifying prepaid expenses.
