Lesson
Learn the simple rules that make accounting clear, fair, and reliable.
Understand important accounting principles with easy examples from small businesses.
Concept explanation
Accounting principles are simple rules that guide how business transactions should be recorded.
Just like traffic rules help everyone drive safely, accounting principles help everyone record business transactions clearly.
If every business records things in a different way, accounts become confusing.
Principles create a common way of recording.
Simple line: accounting principles make accounts reliable, fair, and easy to understand.
They help us record transactions correctly.
They keep business and owner separate.
They help compare one year with another year.
They avoid showing false profit.
They record income and expenses in the correct period.
They help prepare final accounts properly.
They make accounts understandable to owners, banks, teachers, students, and others.
Riya runs a small mobile accessories shop.
In one month, she buys earphones for Rs.20,000 and sells goods worth Rs.30,000.
Some goods are sold on credit.
Shop rent of Rs.5,000 is unpaid.
She takes Rs.2,000 from business cash for personal use.
She buys a table for Rs.8,000.
If Riya records all this without rules, she may treat personal withdrawal as shop expense, ignore credit sales, forget unpaid rent, treat the table as a one-day expense, and show wrong profit.
Accounting principles help her avoid these mistakes.
Business Entity Concept: business and owner are treated separately. If Riya takes Rs.2,000 from business cash for personal use, treat it as Drawings, not shop expense.
Money Measurement Concept: only things that can be measured in money are recorded. Bought goods for Rs.20,000 is recorded, but Riya is hardworking is not recorded.
Going Concern Concept: business is assumed to continue in future. A table bought for Rs.8,000 is treated as an asset, not a one-day expense.
Accounting Period Concept: business life is divided into fixed periods to calculate profit or loss.
Cost Concept: assets are recorded at their purchase cost. Furniture bought for Rs.8,000 is recorded at Rs.8,000.
Dual Aspect Concept: every transaction has two sides. Started business with cash Rs.50,000 means cash increases and capital increases.
Accrual Concept: income and expenses are recorded when they become due, not only when cash is received or paid.
Matching Concept: expenses of a period should be matched with income of the same period.
Revenue Recognition Concept: revenue is recorded when it is earned, such as credit sales recorded when goods are sold.
Consistency: use the same accounting method every year unless there is a good reason to change.
Conservatism or Prudence: do not show profit too early or too high. Record possible losses carefully.
Materiality: important items should be shown properly. Very small items can be treated simply.
Full Disclosure: important information should be clearly shown, such as a big business loan.
