Day 4: Revenue, Income, Profit, Gain & Loss
In Day 3 we mastered Receipts & Expenditure. Today in Day 4, we go through five closely related but distinctly different terms — Revenue, Income, Profit, Gain, and Loss — and see exactly how they flow through a real Income Statement with actual numbers. This is the heart of every P&L Account! 📊
📖 Key Definitions
Revenue
Business ki main operations se earned paisa — goods selling ya services provide karne se. Yeh business ka primary income source hai.
Income
Broader term — Revenue + any other earnings (like interest received, rent received). Income = Revenue + Other Income sources.
Profit
Jab Revenue ya Income, Expenses se zyada hoti hai tab profit hota hai. Do types: Gross Profit (Revenue − COGS) and Net Profit (G.P − Indirect Expenses).
Gain
Profit jo incidental ya non-regular activities se arise hota hai — yeh business ki main operations se nahi hota. Ek off-type benefit.
Loss
Jab koi asset book value se neeche bika ho — ya jab total expenses income se zyada ho. Yeh income reduce karta hai.
Gain vs Profit — Key Difference
Profit arises from the main business operations (selling goods/services). Gain arises from incidental or non-regular activities (like selling an old asset). Both are positive — but they have different origins!

🔍 Concept Deep Dives
💰 What is COGS (Cost of Goods Sold)?
COGS woh direct cost hai jo goods produce karne mein lagti hai. Isme teen cheezein aati hain: Raw Material (RM) — maal banana ka kachcha saman; Direct Labor — directly production mein lage workers ki salary; aur Manufacturing Expenses (Mfr. Exp) — factory mein production ke direct kharche. COGS = Sales Revenue se sidha ghataate hain, to Gross Profit milta hai.
📊 Gross Profit vs Net Profit
Gross Profit = Revenue − COGS — Yeh sirf production cost nikalne ke baad bacha paisa hai. Isme indirect expenses abhi nahi ghate.
Net Profit = Gross Profit − Indirect Expenses — Ab rent, electricity, salaries jaise sab operating kharche ghataane ke baad jo bachta hai woh Net Profit hai. Net Profit business ki actual profitability dikhata hai.
✅ Gain — Incidental Profit
Gain tab hota hai jab business koi non-regular activity se paisa kamata hai — jaise purana furniture ya equipment bechna. Yeh main business operations ka hissa nahi hai. Gain ko Net Profit mein add karte hain kyunki yeh ek extra positive inflow hai. Example: Purana furniture ₹5,000 mein becha → Gain = ₹5,000.
📉 Loss — Asset Sold Below Book Value
Loss tab hota hai jab koi asset uski book value se kam price par bichi ho. Book value = original cost − depreciation. Agar machinery ki book value ₹10,000 thi aur ₹7,000 mein bichi, to ₹3,000 ka loss. Yeh loss Total Income se ghataate hain, jo Adjusted Income deta hai.
📥 Income vs Revenue — The Difference
Revenue sirf main business se aata hai (Sales). Income ek wider term hai — isme Revenue + Gains + any other earnings shamil hain. Isliye note mein pehle Net Profit (₹28,000) hai, phir Gain add hota hai (₹5,000) aur Total Income (₹33,000) banta hai — Income = Profit + Gain.
Common Exam Mistake
Many students confuse Gross Profit and Net Profit. Remember: Gross Profit only deducts direct costs (COGS). Net Profit additionally deducts indirect expenses (Rent, Salary, Admin). Always check which level of profit is being asked!
Connection with Previous Days
Day 2: COGS uses Raw Materials (Current Assets → Inventory).
Day 3: Indirect Expenses = Revenue Expenditure. Machinery purchase = Capital Expenditure — its sale at a loss creates the “Loss” entry here.
Day 3: Gain from selling old furniture = Capital Receipt (non-recurring).
