What is an operating expense – Definition and Key Business Examples

Operating expenses have a direct impact on monthly profitability, as they cover necessary daily expenses such as rent, payroll, and utilities that keep your business open and running smoothly.

 You can improve your cash flow, reduce waste, and adjust spending to sales fluctuations by differentiating between fixed, variable, and semi-variable expenses.

By monitoring and improving operating costs, you can boost profits without increasing sales and free up funds for more sustainable business growth. 

The regular costs of running a business, such as rent, payroll, and electricity, are referred to as operating expenses. Regular payments are necessary to keep the business operating, but they are not significant investments.

Understanding Operating Expenses with Aman’s Example

Aman owns a small cafe. His operating expenses include:
 

• Rent: ₹20,000 per month
   
• Salaries: ₹50,000 per month
   
• Electricity & Water: ₹8,000 per month
   
• Coffee Beans & Supplies: ₹30,000 per month
   
• Marketing: ₹5,000 per month

These expenses enable Aman to provide daily customer service. His café wouldn't be able to operate without them.

Here’s a breakdown of Aman’s monthly operating expenses:
 

This table shows how Aman spends ₹1,13,000 monthly just to keep his café open.

For any business to function correctly, operating expenses are required. Aman ensures his café remains profitable by keeping a close eye on it. This blog provides a straightforward explanation of operating costs.

Bonus Tips: Operating expenses for a public company can be found in its Income Statement, also known as the Profit and Loss (P&L) Statement. These expenses are subtracted from revenue to determine operating income.

Types of Operating Expenses 

Managing a business entails handling various expenses daily. While some costs are constant, others vary according to production or sales. These can be divided into fixed, variable, and semi-variable costs and are referred to as operating expenses.

Business owners like Akash can better manage their finances by being aware of these categories. Let's dissect them using actual instances.

What Are the Different Types of Operating Expenses?

Operating expenses are the regular costs of running a business. They can be:
 

1. Fixed Costs: The same every month (e.g., rent).
    
2. Variable Costs: Change in proportion to sales (such as raw materials).
    
3. Semi-Variable Costs: Partly fixed, partly variable (like electricity).

Example: Akash’s Clothing Store

Akash owns a small clothing shop. Here’s how his expenses break down:
 

This table shows how Akash’s costs behave differently.

Why Does This Matter?

Knowing these types helps Akash:
 

• Plan budgets (fixed costs are predictable).
   
• Control spending (variable costs can be adjusted).
   
• Save money (negotiate better deals on semi-variable costs).

1. Fixed Operating Expenses (Never Change)

These costs stay the same, no matter how much Akash sells.

Examples:
 

• Rent: ₹25,000 per month (same even if sales drop).
   
• Salaries: ₹60,000 per month (fixed wages for staff).
   
• Insurance: ₹5,000 per month (regular premium).

Why Fixed Costs Matter?
 

• Easy to budget since they don’t fluctuate.
   
• It must be paid even in slow business months.

2. Variable Operating Expenses (Change with Sales)

These costs go up or down based on Akash’s sales or production.

Examples:
 

• Raw Materials: ₹50,000 (more clothes = more fabric).
   
• Packaging: ₹10,000 (more orders = more boxes).
   
• Sales Commissions: ₹15,000 (higher sales = more payouts).

Why Variable Costs Matter?
 

• It can be reduced if sales are low.
   
• Directly linked to business activity.

3. Semi-Variable Operating Expenses (Mixed Costs)

These have a fixed base + extra charges based on usage.
 

Examples:
 

• Electricity Bill: ₹8,000 (₹5,000 base + ₹3,000 extra usage).
   
• Internet Bill: ₹2,000 (₹1,500 plan + ₹500 extra data).

Why Do Semi-Variable Costs Matter?
 

• Partially controllable (can reduce extra usage).
   
• Need monitoring to avoid overspending.

Understanding fixed, variable, and semi-variable expenses helps business owners like Akash manage their cash flow more effectively. By tracking these, he can cut unnecessary costs and plan budgets accurately, and boost profits.

Bonus Tips: Loan repayments aren’t categorised as operating expenses. While the interest part of your loan payment counts as an operating expense and can be tax-deductible, the principal repayment is considered a financing activity, so it doesn't appear on the income statement’s operating expenses.

Why Operating Expenses Matter for Businesses?

Making sales is only one aspect of running a business; another is effectively controlling expenses. The regular costs that keep your business running are known as operating expenses, and they have the potential to reduce your profits if they are not managed.

Consider Nitin, who runs a modest printing business. He didn't initially keep a close eye on his spending. But his business became more stable and profitable after he began tracking and optimising his Operating Expenses.

Let’s see how focusing on Operating Expenses made a big difference for Nitin.

Why Should You Care About Operating Expenses?

Operating expenses directly impact:
 

• Profitability (Higher OpEx = Lower profits)
   
• Cash flow (Uncontrolled costs = Money problems)
   
• Business growth (Savings can be reinvested)

Nitin’s Business: Before vs. After Tracking Operating Expenses
 

This table shows how, just by controlling expenses, Nitin increased his profit by 60% without increasing sales!

How Operating Expenses Impact Your Business?

1. Higher Profit Margins
 

• Before: Nitin spent ₹1,50,000 per month on rent, salaries, and supplies.
   
• After: He negotiated cheaper rent (₹10,000 savings) and reduced waste (₹5,000 savings).
   
• Result: Same revenue, but ₹30,000 more profit!

2. Better Cash Flow
 

• Uncontrolled Operating Expenses can lead to cash shortages.
   
• Nitin now tracks expenses weekly, avoiding last-minute money crunches.

3. Smarter Business Decisions

• Knowing where money goes helps Nitin:
   
  • Cut unnecessary costs (like unused subscriptions).
     
  • Invest in growth (better machines, marketing).

Key Takeaways:

You see why OpEx matters:
 

• Lower OpEx = Higher profits (even with the same sales).
   
• Good cash flow = Fewer financial surprises.
   
• Smart spending = More money for growth.

A business is made or broken by its operating costs. Nitin found that tracking and optimising operating expenses increased profits without requiring more effort.

Operating Expenses vs. Capital Expenses (OpEx vs. CapEx)

Short-term expenses for day-to-day operations, such as rent and payroll, are known as operating expenses (OpEx) and are fully tax-deductible in the same year. Long-term investments in assets, such as real estate or machinery, that depreciate over time are known as capital expenses, or CapEx.

Key differences between daily operational costs and long-term asset investments.
 

OpEx sustains daily operations, while CapEx builds future growth and value.

Conclusion

Like driving a car, managing a business requires you to keep an eye on your fuel (your expenses) in order to go farther. The regular costs that keep your business running, such as salary, rent, and bills, are known as operating expenses (OpEx). 

They can quickly eat away at your profits if you ignore them. But you can grow, earn more, and save money without putting in more effort if you monitor and manage them like Nitin did. 

Over time, little adjustments, like reducing waste or negotiating better prices, add up to a lot. So, pay attention to your OpEx. It's the best strategy to maintain the long-term viability and strength of your company.
