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).

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

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:

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.

Proforma / Format (as per NCERT)

The Operating Ratio is not presented in a separate "account" format. It is computed from the Statement of Profit and Loss (the vertical format used in Class 12). Below is the relevant extract showing how the figures are arranged:

A Quick Check

If a company's Revenue from Operations is ₹8,00,000 and its Operating Cost is ₹6,40,000, the Operating Ratio is:

This means 80 paise of every rupee goes toward operations, leaving 20 paise as operating profit (before interest and tax).

Key takeaway: The Operating Ratio is your first window into how efficiently a business runs its core operations. A low ratio is good; a high ratio is a warning sign.
