Operating Ratio — A First Look
Think of a shopkeeper who earns ₹100 from sales. She spends ₹70 on buying goods, ₹15 on salaries and rent, and ₹5 on electricity. That leaves her with ₹10 as profit. Now ask: how much of every ₹100 sale is eaten up by her normal business operations? The answer is ₹90 (₹70 + ₹15 + ₹5). That 90% is her Operating Ratio.
In everyday language, the Operating Ratio tells you: "Out of every rupee of revenue from operations, how many paise go toward running the business?" The lower this ratio, the more efficient the business — because a smaller share of revenue is consumed by operating costs.
Precise Meaning (NCERT Definition)
The Operating Ratio is a profitability ratio that measures the proportion of Operating Cost to Revenue from Operations (Net Sales).
Operating Ratio=Revenue from OperationsOperating Cost×100
Where:
- Revenue from Operations = Net Sales (Gross Sales − Sales Returns)
- Operating Cost = Cost of Revenue from Operations + Operating Expenses
Cost of Revenue from Operations = Opening Inventory + Purchases + Direct Expenses − Closing Inventory
(For a trading firm, this is simply Cost of Goods Sold.)
Operating Expenses include:
- Office and administrative expenses (rent, salaries, insurance)
- Selling and distribution expenses (advertising, commission, carriage outward)
- Depreciation on fixed assets used in operations
Non-operating items are excluded. Do NOT include:
- Interest on loans (financial cost)
- Loss on sale of fixed assets
- Donations or charity
- Dividend paid
- Income tax
Why It Matters
A high Operating Ratio (say, above 90%) means the business has very thin margins from its core operations. A low ratio (say, 70%) indicates strong operational efficiency — more revenue is left as operating profit.
Managers use it to:
- Compare efficiency over time (trend analysis)
- Benchmark against competitors
- Identify where costs are rising out of control
Investors and creditors watch it because a rising Operating Ratio often signals trouble before net profit falls.
Accounting Treatment — Which Account is Debited/Credited?
The Operating Ratio is not a journal entry. It is a ratio computed from the Profit & Loss Statement. No account is debited or credited for the ratio itself.
However, the components that go into the ratio are recorded in the usual way:
| Component | Journal Entry (Debit/Credit) |
|---|---|
| Purchases | Debit Purchases A/c, Credit Cash/Supplier A/c |
| Salaries | Debit Salaries A/c, Credit Cash/Bank A/c |
| Depreciation | Debit Depreciation A/c, Credit Accumulated Depreciation A/c |
| Revenue from Operations | Debit Cash/Bank/Debtors A/c, Credit Revenue from Operations A/c |
All these expenses and revenues are then transferred to the Profit & Loss Account at the end of the year. The Operating Ratio is simply a mathematical relationship between two figures already sitting in that account.

›Reveal solutionSolution
'Higher is more favourable' does not apply to the operating ratio - option (a).
The operating ratio = (Cost of goods sold + Operating expenses) / Net sales x 100. It shows the proportion of sales absorbed by operating costs, so a lower operating ratio is favourable (it leaves a higher operating profit). Thus, unlike the net profit or stock turnover ratios (where …
- CBSE 2026Set ANNUAL1 markQ.Profit from sale of Land is ₹ 3,00,000. Will it increase operating profit? Give reason.
›Reveal solutionSolution
No, profit from sale of land will NOT increase operating profit.
Operating Profit is the profit earned from a company's normal, regular business/trading operations alone. Profit (or loss) on sale of a fixed asset such as land is a capital transaction, unrelated to the day-to-day operating activities of the business, and is non-recurring in nature. Hence, while computing Operating Profit from Net Profit, such non-operating gains are specifically EXCLUDED (deducted back out, since they were included in net profit but do not relate to operations). Including it …

Operating ratio is a profitability ratio, so the answer is (A).
Operating Ratio = (Cost of Revenue from Operations + Operating Expenses) / Net Revenue from Operations x 100. It shows what proportion of sales is consumed by operating costs and therefore indicates the operating profitability of the business.

- CBSE 2025Set ANNUAL1 markMCQQ.Higher the ratio, lower the profitability, is applicable to(a) gross profit ratio(b) operating ratio(c) net profit ratio(d) earning per share
›Reveal solutionSolution
Operating Ratio = (Cost of Revenue from Operations + Operating Expenses) / Revenue from Operations × 100 — since it measures cost as a fraction of sales, a HIGHER ratio means LOWER profit margin, the opposite relationship to profitability ratios like Gross/Net Profit Ratio.
Most profitability ratios (Gross Profit Ratio, Net Profit Ratio, Earning Per Share) move in the SAME direction as profitability — a higher value means better profitability. The Operating Ratio is the exception: it is a cost ratio, computed as
Operating Ratio = (Cost of Revenue from Operations + Operating Expenses) ÷ Revenue from Operations × 100

›Reveal solutionSolution
Part (a): Cost of Revenue from Operations = ₹8,00,000 — option (D).
Part (b): Operating Profit Ratio = 40% — option (C).
Part (a) — Cost of Revenue from Operations
"Gross profit is 25% on cost" means the base of the percentage is cost: for every ₹100 of cost, gross profit is ₹25, so Revenue from Operations = ₹125. Therefore Revenue = 125% of Cost.
Cost of Revenue from Operations = Revenue ÷ 1.25 = ₹10,00,000 ÷ 1.25 = ₹8,00,000.
Verification: Gross profit = 25% of ₹8,00,000 = ₹2,00,000; Cost (₹8,00,000) + Gross profit (₹2,00,000) = ₹10,00,000 = Revenue from Operations. ✓ …
