- Net loss = when total expenses exceed total income
Understanding Profit and Loss Account
After calculating gross profit in the Trading Account, businesses need to know their actual profit after paying all expenses. This is where the Profit and Loss Account comes in. Think of it as the second stage of finding out whether a business truly succeeded or failed.
For example, a phone shop in Abuja might make ₦2 million gross profit from selling phones. But after paying shop rent, staff salaries, NEPA bills, and other expenses, the actual profit might be only ₦800,000. The Profit and Loss Account shows this complete picture.
Purpose of Profit and Loss Account
The Profit and Loss Account serves several important purposes:
1. Determine True Profitability: It shows whether the business made real profit after all expenses. Gross profit alone does not tell the full story.
2. Control Expenses: Business owners can see which expenses are too high and need reduction. If transport costs jumped from ₦50,000 to ₦200,000, the owner will notice and investigate.
3. Plan for Future: By studying expenses patterns over months or years, businesses can budget better for the coming period.
4. Attract Investors: Banks and investors want to see the Profit and Loss Account before lending money. Consistent net profit shows the business is healthy.
5. Tax Calculation: The Federal Inland Revenue Service (FIRS) uses net profit from this account to calculate company tax in Nigeria.
Structure of Profit and Loss Account
The Profit and Loss Account can be presented in two formats, just like the Trading Account:
Horizontal (T) Format
In this traditional format:
- Debit side (left): All expenses like rent, salaries, insurance, electricity, depreciation
- Credit side (right): Gross profit brought from Trading Account, plus any other income like commission received, rent received, discount received
If total credit side is bigger than debit side, the difference is net profit. If debit side is bigger, the difference is net loss.
Vertical Format
Most modern Nigerian businesses use this format because it is clearer and easier to understand. You start with gross profit at the top, add other incomes, then subtract all expenses to reach net profit at the bottom.

Calculating Net Profit or Net Loss
Formula in Vertical Format:
Gross Profit
Add: Other incomes
Less: All expenses
= Net Profit (or Net Loss)
Example:
Bisi’s Fashion House in Aba prepared these figures for December:
- Gross profit: ₦450,000
- Salaries: ₦80,000
- Rent: ₦50,000
- Electricity: ₦25,000
- Advertising: ₦15,000
- Commission received: ₦20,000
- Discount allowed: ₦10,000
Calculation:
Gross profit: ₦450,000
Add: Commission received: ₦20,000
Total: ₦470,000
Less: Expenses
Salaries: ₦80,000
Rent: ₦50,000
Electricity: ₦25,000
Advertising: ₦15,000
Discount allowed: ₦10,000
Total expenses: ₦180,000
Net Profit = ₦470,000 – ₦180,000 = ₦290,000
Net Profit vs Net Loss
Net Profit occurs when: Total income (gross profit + other incomes) is greater than total expenses. The business is successful and profitable. The owner can withdraw some profit or keep it in the business as retained earnings.
Net Loss occurs when: Total expenses are greater than total income. The business spent more than it earned. This reduces the owner’s capital. If losses continue for many periods, the business may close down.
In Nigeria, many businesses face net losses during economic recessions when costs rise but sales drop. Smart business owners reduce expenses quickly to prevent continuous losses.
Transfer to Balance Sheet
After calculating net profit or net loss in the Profit and Loss Account:
- Net Profit: Added to the owner’s capital on the Balance Sheet. It increases the owner’s stake in the business.
- Net Loss: Subtracted from the owner’s capital on the Balance Sheet. It reduces what the business owes the owner.
This completes the accounting cycle from Trading Account to Profit and Loss Account to Balance Sheet.
Common Exam Mistakes
WAEC examiners report these errors:
- Mixing Trading Account and P&L items: Students put salaries and rent in Trading Account. Remember: Trading Account handles only goods (purchases, sales, stock). All other expenses go to Profit and Loss Account.
- Wrong placement of carriage: Carriage inwards goes to Trading Account (cost of bringing goods in). Carriage outwards goes to Profit and Loss Account (cost of sending goods out). Many students reverse this.
- Forgetting to bring gross profit: Some candidates start the Profit and Loss Account fresh without transferring gross profit from Trading Account. You must start with gross profit!
- Adding expenses instead of subtracting: In vertical format, expenses should be subtracted from income, not added. Check your arithmetic signs carefully.
- Confusing discount allowed and discount received: Discount allowed is an expense (you gave reduction). Discount received is income (you got reduction). Students often swap these.
- Not balancing properly: When using T format, students forget that net profit goes on the debit side to balance the account. Net loss goes on credit side.

Essay Questions
Question 1 (10 marks):
State five items that appear on the debit side of the Profit and Loss Account.
Examiner’s tip: Just list the items clearly. For “state” questions, you don’t need long explanations. Make sure each item truly belongs to P&L Account, not Trading Account.
Question 2 (15 marks):
From the following information, prepare the Profit and Loss Account for Okoro Enterprises for the year ended December 31, 2024:
– Gross profit: ₦680,000
– Salaries: ₦120,000
– Rent and rates: ₦80,000
– Insurance: ₦25,000
– Discount allowed: ₦18,000

– Commission received: ₦35,000
– Bad debts: ₦15,000
– Depreciation: ₦40,000
– Advertising: ₦28,000
Examiner’s tip: Use vertical format unless the question specifies T format. Show clear headings. Calculate total income first, then total expenses, then subtract to get net profit. Show all workings.
Question 3 (10 marks):
Explain five differences between Trading Account and Profit and Loss Account.
Examiner’s tip: For “explain” questions, write 2-3 sentences for each difference. Don’t just state the difference – explain why it matters and give examples where helpful.
Question 4 (5 marks):
Distinguish between gross profit and net profit.
Examiner’s tip: “Distinguish” means show the differences clearly. Explain how gross profit is calculated in Trading Account, while net profit comes from Profit and Loss Account after deducting all expenses.
Memory Aids
Remember “GRID” for what goes to Profit and Loss Account:
Gross profit (starting point)
Running expenses (salaries, rent, utilities)
Income (other than sales)
Discounts and bad debts
Carriage placement: “IN to Trade, OUT to Profit”
Carriage INwards → Trading Account
Carriage OUTwards → Profit and Loss Account
Position of net profit in T format: “Profit Decreases Debits”
Net Profit goes on Debit side (to balance)
Net Loss goes on Credit side (to balance)
Remember discounts: “Allowed Away, Received Reward”
Discount Allowed = You gave it away = Expense (debit)
Discount Received = You received reward = Income (credit)
