Operating Ratio vs Operating Profit Ratio

Operating ratio and operating profit ratio are like two sides of the same business story.

One ratio asks:

How much of sales is being used up by operating costs?

The other ratio asks:

How much of sales is left as operating profit?

That is why students often study them together. The formulas look different, but the idea is connected. If a business spends more on operating cost, its operating profit margin falls. If it controls operating cost well, its operating profit margin improves.

Once this relationship is clear, the topic becomes much easier than memorising two separate formulas.

The Big Idea Behind These Ratios

A business earns revenue from its main activity. For a trading business, that usually means selling goods. For a service business, it may mean providing services.

But revenue is not profit.

To earn that revenue, the business must spend money on goods, wages, salaries, office expenses, selling expenses, delivery expenses, and other normal running costs.

Operating ratio compares these normal operating costs with revenue from operations.

Operating profit ratio compares the profit left after those normal operating costs with revenue from operations.

Think of revenue as water flowing into a tank.

Operating costs are the pipes through which water is used for running the business.

Operating profit is the water left after those running costs are covered.

Ratio	Main question	Better when
Operating Ratio	How much revenue is consumed by operating cost?	Lower
Operating Profit Ratio	How much revenue remains as operating profit?	Higher

This is the core difference.

Important Terms You Must Know First

Before calculating either ratio, you need three terms to be clear:

1. Net revenue from operations
2. Operating cost
3. Operating profit

If these three are clear, the formulas become simple.

Net Revenue From Operations

Net revenue from operations means revenue earned from the main business activity after deducting returns and similar reductions.

In many questions, it is simply given as revenue from operations or net sales.

For a trading concern, it usually means:

Net Revenue from Operations = Cash Sales + Credit Sales - Sales Returns

If the question gives revenue from operations directly, use that figure.

That means income from investments, profit on sale of an old asset, or other side income should not be mixed with revenue from operations.

Operating Cost

Operating cost means the cost of running the main business activity.

It has two main parts:

Part	Meaning
Cost of revenue from operations	Cost related to goods or services sold
Operating expenses	Normal office, administrative, selling, and distribution expenses

The formula is:

Operating Cost = Cost of Revenue from Operations + Operating Expenses

For a trading business, cost of revenue from operations may be calculated like this:

Cost of Revenue from Operations = Opening Inventory + Net Purchases + Direct Expenses - Closing Inventory

Operating expenses usually include items such as:

• office expenses
• administrative expenses
• salaries
• selling expenses
• distribution expenses
• carriage outwards
• advertisement expenses

The exact treatment depends on what is given in the question, but the idea is simple: include expenses connected with normal operations.

Operating Profit

Operating profit is the profit earned from normal business operations.

It can be calculated in different ways depending on the information given.

If the question gives	Use this method
Revenue and operating cost	Operating Profit = Net Revenue from Operations - Operating Cost
Gross profit and operating expenses	Operating Profit = Gross Profit - Operating Expenses
Net profit with non-operating items	Operating Profit = Net Profit + Non-operating Expenses - Non-operating Incomes

Non-operating incomes and expenses are not part of normal business operations.

Examples of non-operating incomes may include:

• interest received on investments
• dividend income
• profit on sale of fixed assets

Examples of non-operating expenses may include:

• interest on loan
• loss on sale of fixed assets
• unusual losses not connected with normal operations

Operating Ratio Meaning

Operating ratio shows the relationship between operating cost and net revenue from operations.

It tells us how much of every Rs. 100 of revenue is being used to cover operating cost.

The formula is:

Formula	Meaning
Operating Ratio = Operating Cost / Net Revenue from Operations x 100	Shows the percentage of revenue consumed by operating cost

Since:

Operating Cost = Cost of Revenue from Operations + Operating Expenses

The full formula can also be written as:

Operating Ratio = (Cost of Revenue from Operations + Operating Expenses) / Net Revenue from Operations x 100

For example, if operating ratio is 82%, it means Rs. 82 out of every Rs. 100 of revenue is used for operating cost.

That leaves Rs. 18 as operating profit.

Operating Profit Ratio Meaning

Operating profit ratio shows the relationship between operating profit and net revenue from operations.

It tells us how much of every Rs. 100 of revenue remains as operating profit after covering operating cost.

The formula is:

Formula	Meaning
Operating Profit Ratio = Operating Profit / Net Revenue from Operations x 100	Shows the percentage of revenue left as operating profit

Operating profit can be calculated as:

Operating Profit = Net Revenue from Operations - Operating Cost

So, if operating profit ratio is 18%, it means Rs. 18 out of every Rs. 100 of revenue remains as operating profit.

The Relationship Between the Two Ratios

Operating ratio and operating profit ratio are directly connected.

If both ratios are calculated using the same net revenue from operations, then:

Operating Ratio + Operating Profit Ratio = 100%

So:

Operating Profit Ratio = 100 - Operating Ratio

And:

Operating Ratio = 100 - Operating Profit Ratio

This happens because revenue is divided into two parts:

1. Operating cost
2. Operating profit

Together, they make up the full revenue from operations.

This one connection can save a lot of time in exam questions.

Operating Ratio vs Operating Profit Ratio

Here is the clean comparison:

Basis	Operating Ratio	Operating Profit Ratio
Main focus	Cost of operations	Profit from operations
Numerator	Operating cost	Operating profit
Denominator	Net revenue from operations	Net revenue from operations
Form	Percentage	Percentage
Better result	Lower ratio	Higher ratio
Formula link	100 - Operating Profit Ratio	100 - Operating Ratio
Main use	Measures cost control	Measures operating margin

Operating ratio is a cost ratio.

Operating profit ratio is a profitability ratio.

Both use the same revenue base, but they look at opposite sides of that revenue.

How to Interpret Operating Ratio

A lower operating ratio is usually better.

Why?

Because it means the business is using a smaller part of its revenue to cover operating cost. More revenue is available as operating profit.

A higher operating ratio is usually a warning sign. It may mean operating cost is too high compared with revenue.

Operating ratio position	General interpretation
Low	Better cost control and stronger operating efficiency
High	Operating cost is consuming too much revenue
Falling over time	Cost control may be improving
Rising over time	Operating efficiency may be weakening

But do not judge blindly.

Some businesses naturally have higher operating costs than others. A grocery store, a transport business, a manufacturing unit, and a consulting business may all have very different cost structures.

That is why interpretation should be balanced.

How to Interpret Operating Profit Ratio

A higher operating profit ratio is usually better.

It means the business keeps a larger share of revenue as operating profit.

For example, an operating profit ratio of 24% means the business earns Rs. 24 as operating profit for every Rs. 100 of revenue from operations.

Operating profit ratio position	General interpretation
High	Stronger operating margin
Low	Weak operating margin
Rising over time	Profit from operations may be improving
Falling over time	Operating cost may be increasing faster than revenue

A low operating profit ratio does not always mean the business is failing. It may be in a low-margin industry, or it may be spending more to expand.

Still, in a classroom ratio question, the usual answer is:

• higher operating profit ratio shows better operating profitability
• lower operating profit ratio shows weaker operating profitability

This is the simplest way to remember the interpretation.

Solved Example 1: Direct Calculation

Calculate operating ratio and operating profit ratio from the following information:

Particulars	Amount
Net revenue from operations	Rs. 5,00,000
Cost of revenue from operations	Rs. 3,00,000
Selling expenses	Rs. 60,000
Administrative expenses	Rs. 40,000

Step 1: Calculate Operating Expenses

Operating Expenses = Selling Expenses + Administrative Expenses
Operating Expenses = Rs. 60,000 + Rs. 40,000
Operating Expenses = Rs. 1,00,000

Step 2: Calculate Operating Cost

Operating Cost = Cost of Revenue from Operations + Operating Expenses
Operating Cost = Rs. 3,00,000 + Rs. 1,00,000
Operating Cost = Rs. 4,00,000

Step 3: Calculate Operating Ratio

Operating Ratio = Operating Cost / Net Revenue from Operations x 100
Operating Ratio = Rs. 4,00,000 / Rs. 5,00,000 x 100
Operating Ratio = 80%

Step 4: Calculate Operating Profit

Operating Profit = Net Revenue from Operations - Operating Cost
Operating Profit = Rs. 5,00,000 - Rs. 4,00,000
Operating Profit = Rs. 1,00,000

Step 5: Calculate Operating Profit Ratio

Operating Profit Ratio = Operating Profit / Net Revenue from Operations x 100
Operating Profit Ratio = Rs. 1,00,000 / Rs. 5,00,000 x 100
Operating Profit Ratio = 20%

Interpretation

Operating ratio is 80%. This means Rs. 80 out of every Rs. 100 of revenue is used for operating cost.

Operating profit ratio is 20%. This means Rs. 20 out of every Rs. 100 of revenue remains as operating profit.

Together, the two ratios make 100%.

80% + 20% = 100%

Solved Example 2: When Gross Profit Is Given

Sometimes the question gives gross profit instead of cost of revenue from operations.

Calculate operating ratio and operating profit ratio:

Particulars	Amount
Net revenue from operations	Rs. 8,00,000
Gross profit	Rs. 2,80,000
Office expenses	Rs. 90,000
Selling and distribution expenses	Rs. 70,000

Step 1: Calculate Cost of Revenue from Operations

Gross Profit = Net Revenue from Operations - Cost of Revenue from Operations
Cost of Revenue from Operations = Net Revenue from Operations - Gross Profit
Cost of Revenue from Operations = Rs. 8,00,000 - Rs. 2,80,000
Cost of Revenue from Operations = Rs. 5,20,000

Step 2: Calculate Operating Expenses

Operating Expenses = Office Expenses + Selling and Distribution Expenses
Operating Expenses = Rs. 90,000 + Rs. 70,000
Operating Expenses = Rs. 1,60,000

Step 3: Calculate Operating Cost

Operating Cost = Cost of Revenue from Operations + Operating Expenses
Operating Cost = Rs. 5,20,000 + Rs. 1,60,000
Operating Cost = Rs. 6,80,000

Step 4: Calculate Operating Ratio

Operating Ratio = Rs. 6,80,000 / Rs. 8,00,000 x 100
Operating Ratio = 85%

Step 5: Calculate Operating Profit Ratio

You can calculate operating profit first:

Operating Profit = Gross Profit - Operating Expenses
Operating Profit = Rs. 2,80,000 - Rs. 1,60,000
Operating Profit = Rs. 1,20,000

Now apply the formula:

Operating Profit Ratio = Rs. 1,20,000 / Rs. 8,00,000 x 100
Operating Profit Ratio = 15%

Or use the shortcut:

Operating Profit Ratio = 100 - Operating Ratio
Operating Profit Ratio = 100 - 85
Operating Profit Ratio = 15%

Both methods give the same answer.

Solved Example 3: Adjusting Non-Operating Items

This is where many students lose marks.

Calculate operating profit ratio from the following information:

Particulars	Amount
Net revenue from operations	Rs. 10,00,000
Net profit	Rs. 1,10,000
Interest on loan	Rs. 30,000
Loss on sale of machinery	Rs. 20,000
Interest received on investment	Rs. 10,000
Profit on sale of investment	Rs. 5,000

Here, net profit includes non-operating items. We need to adjust them to find operating profit.

Step 1: Add Non-Operating Expenses

Interest on loan and loss on sale of machinery are not part of normal operations.

Non-operating Expenses = Rs. 30,000 + Rs. 20,000
Non-operating Expenses = Rs. 50,000

Step 2: Subtract Non-Operating Incomes

Interest received on investment and profit on sale of investment are not part of normal operations.

Non-operating Incomes = Rs. 10,000 + Rs. 5,000
Non-operating Incomes = Rs. 15,000

Step 3: Calculate Operating Profit

Operating Profit = Net Profit + Non-operating Expenses - Non-operating Incomes
Operating Profit = Rs. 1,10,000 + Rs. 50,000 - Rs. 15,000
Operating Profit = Rs. 1,45,000

Step 4: Calculate Operating Profit Ratio

Operating Profit Ratio = Operating Profit / Net Revenue from Operations x 100
Operating Profit Ratio = Rs. 1,45,000 / Rs. 10,00,000 x 100
Operating Profit Ratio = 14.5%

So, the business earns Rs. 14.50 as operating profit for every Rs. 100 of revenue from operations.

The related operating ratio is:

Operating Ratio = 100 - 14.5
Operating Ratio = 85.5%

How to Decide What to Include

Use this quick checklist when a question has many items.

Item	Include in operating cost?	Reason
Cost of goods sold or cost of revenue	Yes	Directly connected with operations
Office expenses	Yes	Normal operating expense
Selling expenses	Yes	Normal operating expense
Distribution expenses	Yes	Normal operating expense
Administrative expenses	Yes	Normal operating expense
Interest on loan	No	Finance cost, not operating cost
Dividend income	No	Non-operating income
Profit on sale of fixed asset	No	Not from normal operations
Loss on sale of fixed asset	No	Non-operating expense
Tax	No	Not an operating cost for this ratio

This table is not for memorising blindly. It is meant to train your thinking.

Ask one question:

Is this item part of running the main business activity?

If yes, it is usually operating.

If no, keep it outside operating cost and operating profit.

Common Mistakes to Avoid

Mistake 1: Thinking Higher Operating Ratio Is Better

This is the most common confusion.

Operating ratio is a cost ratio. A higher operating ratio means more revenue is being used up by operating cost.

So, a lower operating ratio is generally better.

Mistake 2: Thinking Lower Operating Profit Ratio Is Better

Operating profit ratio is a profit ratio. A higher operating profit ratio means more revenue is left as operating profit.

So, a higher operating profit ratio is generally better.

Mistake 3: Forgetting That Both Ratios Add to 100%

If operating ratio is 72%, operating profit ratio should be 28%.

If your answer gives 72% and 35%, something is wrong.

This quick check is very useful.

Mistake 4: Mixing Net Profit With Operating Profit

Net profit may include non-operating incomes and expenses.

Operating profit should focus on normal business operations.

If the question gives non-operating items, adjust them.

Mistake 5: Including Interest in Operating Cost

Interest on loan or debentures is usually a finance cost. It is not part of operating cost for operating ratio.

Do not include it unless the question clearly gives a special instruction.

Mistake 6: Using Gross Profit as Operating Profit

Gross profit and operating profit are not the same.

Gross profit is before operating expenses such as office, administrative, selling, and distribution expenses.

Operating profit is after these expenses.

Operating Profit = Gross Profit - Operating Expenses

Mistake 7: Ignoring the Word “Net”

If sales returns are given, calculate net revenue from operations first.

Do not use gross sales when net revenue is needed.

A Simple Memory Trick

Use this line:

Operating ratio eats revenue. Operating profit ratio saves what is left.

If operating ratio eats 78% of revenue, operating profit ratio saves 22%.

If operating ratio eats 90% of revenue, operating profit ratio saves only 10%.

That is the whole relationship.

How to Present the Answer Cleanly

In a calculation question, use this order:

1. Write net revenue from operations.
2. Calculate cost of revenue from operations, if needed.
3. Add operating expenses to find operating cost.
4. Calculate operating ratio.
5. Calculate operating profit.
6. Calculate operating profit ratio.
7. Add a one-line interpretation if asked.

Here is a neat answer format:

Step	What to write
Formula	Operating Ratio = Operating Cost / Net Revenue from Operations x 100
Working note	Operating Cost = Cost of Revenue from Operations + Operating Expenses
Substitution	Rs. 4,00,000 / Rs. 5,00,000 x 100
Answer	Operating Ratio = 80%
Check	Operating Profit Ratio = 100 - 80 = 20%

This format makes your working easy to follow.

Final Understanding

Operating ratio and operating profit ratio are both used to study operating efficiency.

Operating ratio looks at cost control.

Operating profit ratio looks at operating margin.

The two ratios are connected because revenue from operations is split into operating cost and operating profit.

If the business controls operating cost, operating ratio falls and operating profit ratio rises.

If operating cost increases faster than revenue, operating ratio rises and operating profit ratio falls.

That is the practical meaning behind the formulas.

Frequently Asked Questions

What is operating ratio?

Operating ratio shows the relationship between operating cost and net revenue from operations. It tells how much of every Rs. 100 of revenue is used for operating cost.

What is the formula for operating ratio?

The formula is:

Operating Ratio = Operating Cost / Net Revenue from Operations x 100

Operating cost means cost of revenue from operations plus operating expenses.

What is operating profit ratio?

Operating profit ratio shows the relationship between operating profit and net revenue from operations. It tells how much of every Rs. 100 of revenue remains as operating profit.

What is the formula for operating profit ratio?

The formula is:

Operating Profit Ratio = Operating Profit / Net Revenue from Operations x 100

Operating profit means net revenue from operations minus operating cost.

What is the difference between operating ratio and operating profit ratio?

Operating ratio focuses on operating cost. Operating profit ratio focuses on operating profit. Operating ratio is better when it is lower, while operating profit ratio is better when it is higher.

Why do operating ratio and operating profit ratio add to 100%?

They add to 100% because net revenue from operations is divided into two parts: operating cost and operating profit. If operating cost takes 80% of revenue, operating profit is the remaining 20%.

Is a high operating ratio good?

Usually no. A high operating ratio means operating cost is consuming a large part of revenue. A lower operating ratio generally shows better cost control.

Is a high operating profit ratio good?

Usually yes. A high operating profit ratio means a larger part of revenue remains as operating profit after operating cost is covered.

Is gross profit the same as operating profit?

No. Gross profit is calculated before deducting operating expenses. Operating profit is calculated after deducting operating expenses from gross profit.

Should interest on loan be included in operating cost?

Usually no. Interest on loan is a finance cost, not a normal operating cost for operating ratio. If the question gives a special instruction, follow that instruction.

Can operating profit ratio be calculated from operating ratio?

Yes. If both ratios use the same net revenue from operations, operating profit ratio can be calculated as 100 minus operating ratio.
