So you’ve just stepped into Class 11 Commerce. Welcome! And if Accountancy feels like a subject full of confusing terms and strange-looking equations — don’t worry. Every topper you look up to once felt exactly the same on Day 1.
The truth is, Accountancy is one of the most scoring subjects in Class 11 and 12 — but only if you build your foundation the right way from the very beginning. And that’s exactly what this post is about.
Let’s start from Chapter 1 and make it simple, practical, and clear.
Chapter 1: Introduction to Accounting — What Is It Really?
Before you open your textbook and start memorising definitions, let me ask you a simple question:
If you run a small shop and sell 10 notebooks for ₹10 each — how do you keep track of your money, your stock, and your profit?
That’s accounting. At its core, Accounting is the process of recording, classifying, summarising, and interpreting financial transactions of a business.
In simple words — it’s the language of business. Every business, from a roadside tea stall to a company like Tata or Reliance, uses accounting to understand:
• How much money came in?
• How much went out?
• What do we own?
• What do we owe?
• Did we make a profit or loss?
Once you understand why accounting exists, the what becomes much easier to learn.
Basic Accounting Terms You Must Know First
Think of these as your vocabulary list. Just like you can’t read a book without knowing words, you can’t do accounting without knowing these terms.
1. Business Entity
The business is treated as separate from its owner. If Ramesh starts a shop, the shop’s money and Ramesh’s personal money are different — always.
Example: Ramesh invests ₹50,000 in his shop. For accounting purposes, the shop owes ₹50,000 to Ramesh (the owner). They are two different “entities.”
2. Capital
Capital is the amount invested by the owner into the business.
Example: Ramesh puts ₹50,000 of his own money into the business. This ₹50,000 is his Capital.
Remember: Capital = Owner’s contribution. It’s what the business owes back to the owner.
3Assets
Assets are everything the business OWNS — things of value.
There are two types:
• Fixed Assets — long-term things like land, building, machinery, furniture
• Current Assets — short-term things like cash, stock, debtors (money owed to us)
Example: Ramesh buys a shop counter for ₹5,000 → it’s a Fixed Asset. He has ₹10,000 cash in hand → Current Asset.
4. Liabilities
Liabilities are everything the business OWES to outsiders.
• Long-term Liabilities — bank loans, debentures
• Current Liabilities — creditors, short-term loans, bills payable
Example: Ramesh takes a loan of ₹20,000 from the bank → Liability.
5. Purchases & Sales
• Purchases — buying goods for resale or production
• Sales — selling those goods
Example: Ramesh buys 100 notebooks for ₹500 → Purchases. He sells them for ₹800 → Sales.
6.Debtor vs. Creditor
• Debtor — someone who owes money TO us (we sold on credit)
• Creditor — someone we owe money TO (we bought on credit)
Memory trick: “D for Debtor = D for Due to us”
7. Revenue & Expenses
• Revenue — money earned by the business (sales, commission received)
• Expenses — money spent to run the business (rent, salary, electricity)
8. Profit & Loss
• Profit = Revenue > Expenses
• Loss = Expenses > Revenue
Simple, right?
9. Stock / Inventory
Goods that remain unsold at the end of the period are called Closing Stock.
Example: Ramesh bought 100 notebooks but sold only 80 → 20 notebooks = Closing Stock.
10. Transaction
Any financial event that can be measured in money is a transaction.
Example: Buying goods, paying salary, receiving rent — all are transactions.
Chatting with a customer? Not a transaction (until money is involved).
⚖️ The Accounting Equation — Where Theory Meets Practice
Now here’s where things get exciting. All of accounting — from Journal Entries to Balance Sheet — is built on one single equation:
Assets = Capital + Liabilities
Or: A = C + L
This equation always balances. Always. No matter what transaction happens in a business, this equation holds true. That’s the magic of double-entry accounting.
Let’s understand this with a practical example step by step.
Practical: Accounting Equation in Action
Let’s follow Ramesh as he starts his business.
Starting Balance (Before any transactions):
Assets = Capital + Liabilities
₹0=₹0+₹0
Transaction 1: Ramesh starts business with ₹50,000 cash
• Cash (Asset) increases by ₹50,000
• Capital increases by ₹50,000
Assets (Cash) =Capital + Liabilities
₹50,000 = ₹50,000 + ₹0
✔️ Equation balanced!
Transaction 2: Bought furniture for ₹10,000 cash
• Furniture (Asset) increases by ₹10,000
• Cash (Asset) decreases by ₹10,000
Assets (Cash + Furniture) = Capital + Liabilities
( ₹40,000 + ₹10,000 ) ₹50,000 = ₹50,000 + ₹0
✔️ Equation still balanced! (Both sides stayed ₹50,000)
Transaction 3: Took a loan of ₹20,000 from bank
• Cash (Asset) increases by ₹20,000
• Loan (Liability) increases by ₹20,000
Assets = Capital + Liabilities
₹70,000 = ₹50,000 + ₹20,000
✔️ Equation balanced!
Transaction 4: Bought goods worth ₹15,000 cash
• Stock/Goods (Asset) increases by ₹15,000
• Cash (Asset) decreases by ₹15,000
Assets (Cash + Furniture + Goods) = Capital + Liabilities
(₹55,000 + ₹10,000 + ₹15,000 )₹70,000 = 50,000 + 20000
(Cash = ₹70,000 – ₹15,000 = ₹55,000)
✔️ Equation balanced!
Transaction 5: Sold goods costing ₹5,000 for ₹8,000 cash (Profit = ₹3,000)
• Cash (Asset) increases by ₹8,000
• Goods/Stock (Asset) decreases by ₹5,000
• Capital increases by ₹3,000 (profit belongs to owner)
Assets = Capital + Liabilities
₹78,000= ₹53,000 + ₹20,000
(Cash = ₹55,000 + ₹8,000 = ₹63,000; Goods = ₹15,000 – ₹5,000 = ₹10,000; Total Assets = ₹63,000 + ₹10,000 + ₹10,000 = ₹83,000… Wait, Furniture ₹10,000 still there)
Total Assets = ₹63,000 (Cash) + ₹10,000 (Furniture) + ₹10,000 (Goods) = ₹83,000
Hmm — let’s recheck:
Capital = ₹50,000 + ₹3,000 profit = ₹53,000
Liabilities = ₹20,000
C + L = ₹73,000
Wait — we need to reconcile. Cash = 55,000 + 8,000 = 63,000. Goods = 15,000 – 5,000 = 10,000. Furniture = 10,000. Total Assets = 83,000.
Capital = 50,000 + 3,000 = 53,000. Liabilities = 20,000. C+L = 73,000.
Difference = ₹10,000 — this is the loan cash we still hold. (The ₹20,000 loan is already in assets as cash from Transaction 3.)
Let’s retrace full assets: Cash starts ₹50,000 → +₹20,000 loan → -₹10,000 furniture → -₹15,000 goods → +₹8,000 sales = ₹53,000 cash. Furniture = ₹10,000. Goods = ₹10,000. Total Assets = ₹73,000.
Assets = Capital + Liabilities
₹73,000 = 53000 +20,00
✔️ Equation perfectly balanced!
Key Takeaway from the Accounting Equation
Every single transaction in a business affects at least two things — that’s why accounting is called Double Entry. And no matter how many transactions happen, Assets will always equal Capital plus Liabilities.
This concept is the backbone of everything you’ll learn ahead — Journal Entries, Ledger, Trial Balance, and Final Accounts are all built on this one equation.
Your Action Plan for Chapter 1
Here’s what to do right now:
1. Learn the 10 basic terms above — don’t just read, write them out once
2. Try the accounting equation yourself — make up 5 transactions of your own and see if the equation balances
3. Watch the video on this topic on my YouTube channel @commercewithanand for a visual explanation
4. Attempt the NCERT exercises at the end of Chapter 1 — they are straightforward once you understand the concepts
Class 11 Accountancy is not hard — it’s just new. Give it 2–3 weeks of consistent effort, focus on understanding over memorising, and you’ll find it becoming your favourite subject.
The students who do well in Accountancy are not the smartest — they’re the ones who practise daily and don’t skip the basics.
You’ve got this. Let’s build it together.
