A Crash Course in Understanding and Improving Your Operating Expenses

As a business owner, you know that every dollar counts when it comes to the bottom line. However, while revenue often gets the most attention, the other side of the profitability equation is just as critical. How much you spend to keep your business running – also known as operating expenses – can make or break your company‘s financial health.

In this crash course, we‘ll take a deep dive into the world of operating expenses. We‘ll cover exactly what counts as an operating expense, why it‘s so important to understand and manage them, and most importantly, proven strategies to optimize and reduce operating costs in your business.

Why Operating Expenses Matter

Let‘s start with a simple truth: you can‘t make money if you‘re spending more than you bring in. That‘s why understanding and controlling operating expenses is so critical for business owners.

A study by CFO Research Services found that 79% of senior finance executives agreed that reducing operating costs is a top priority for their company. And it‘s no wonder – high operating expenses can quickly eat into profits, even if sales are strong.

Consider two companies in the same industry, both generating $10 million in annual revenue. Company A has an operating expense ratio of 80%, meaning they spend $8 million per year on operating costs. Meanwhile, Company B has worked hard to optimize their operating expenses, achieving an OPEX ratio of just 60%. That means Company B spends only $6 million on operating costs, leaving an extra $2 million in profit compared to their competitor.

As this example illustrates, seemingly small improvements in operating efficiency can have a huge impact on the bottom line. That‘s why investors and financial analysts pay close attention to metrics like the operating expense ratio when evaluating a company‘s financial health and market value. All else being equal, a business with lower operating costs will be more profitable, making it a more attractive investment.

The Components of Operating Expenses

So what exactly counts as an operating expense? At a high level, operating expenses include most of the costs necessary to run your business day-to-day. However, operating costs don‘t include the cost of goods sold (COGS) – that‘s the direct cost of producing your products or services, such as raw materials and labor. Other exclusions from operating expenses are interest, taxes, and one-time costs like equipment purchases.

Operating expenses are often split into three categories:

1. Fixed expenses remain relatively stable regardless of sales volume. Common examples are rent, insurance, salaries, and depreciation.

2. Variable expenses fluctuate based on business activity. This might include utilities, advertising spend, sales commissions, or shipping fees.

3. Semi-variable expenses have both fixed and variable components, such as management bonuses or vehicle costs.

Here‘s a breakdown of typical operating expenses for small businesses:

Expense Category	% of Revenue
Salaries and benefits	25-50%
Rent and utilities	10-20%
Marketing and advertising	5-10%
Technology and equipment	3-7%
Vehicle and travel	2-5%
Office supplies and postage	1-3%
Insurance	1-2%
Accounting and legal	1-2%
Other costs	2-5%

Of course, these percentages can vary significantly by industry. For example, a marketing agency will likely spend more on salaries and technology compared to a retail store, which has higher costs related to rent and utilities. It‘s important to understand what the norms are for your specific industry when assessing your operating expenses.

Calculating Operating Expenses

The first step in getting a handle on operating expenses is simply totaling them up. Most accounting software can generate a report showing you operating costs for a given period. If you‘re still using spreadsheets, you‘ll need to add up all the relevant expense categories from your income statement or general ledger.

However, the raw total of operating costs doesn‘t tell you much on its own. To put that number into context, you need to calculate the operating expense ratio. This is simply total operating costs for a period divided by total revenue. The formula looks like this:

Operating Expense Ratio = Operating Costs / Revenue

For example, let‘s say your business had total operating expenses of $500,000 last year and annual revenue of $2 million. The calculation would be:

$500,000 / $2,000,000 = 0.25

Multiply by 100 to express as a percentage:

0.25 x 100 = 25%

In this case, your operating expense ratio is 25%, meaning that a quarter of every dollar you earn gets spent on operating costs.

Knowing your operating expense ratio gives you a high-level look at how efficiently your business generates profit from your core operations. From there, you can compare your OPEX ratio to industry benchmarks and track it over time to spot trends.

It‘s also worth noting that operating expenses factor into a number of other important financial metrics:

• Operating Income = Revenue – Operating Expenses
• Operating Cash Flow = Operating Income +/- Changes in Working Capital
• EBITDA = Operating Income + Depreciation & Amortization

Analyzing Operating Expenses

Calculating your operating expense ratio is an important first step. However, to really understand what‘s driving your costs, you need to dig deeper into the numbers.

Start by looking at each major component of operating expenses on a trend line. Are certain costs increasing faster than revenue growth? That could indicate a problem that needs attention. For example, if your retail store‘s hourly wages are outpacing sales growth, you may need to optimize scheduling or look into automation to control labor costs.

You should also pay attention to how your operating expense ratio compares to industry benchmarks and key competitors. If you‘re spending significantly more than average for your market, that‘s a red flag that you‘re at an efficiency disadvantage.

Another helpful framework is to look at your operating costs on both a vertical and horizontal basis:

• Vertical analysis looks at each operating expense category as a percentage of revenue for a single period, like we did in the table above. This tells you where you‘re spending the most and how that compares to benchmarks.
• Horizontal analysis tracks the change in operating costs over time – either compared to a past period or to budget. This can help you spot trends and see if your cost optimization efforts are working.

Let‘s look at an example of horizontal analysis in action. Say you implemented a new expense reporting software last quarter and want to see how it impacted operating costs. You‘d simply compare this quarter‘s operating expenses to the same period last year:

Expense	Q1 2022	Q1 2023	% Change
Salaries	$500,000	$520,000	4%
Rent	$200,000	$210,000	5%
Technology	$100,000	$80,000	-20%
Travel	$60,000	$55,000	-8%
Total OPEX	$860,000	$865,000	0.6%

This simple analysis tells you that while most costs rose due to inflation and company growth, your new software helped significantly reduce technology and travel expenses, keeping your overall operating costs nearly flat. That‘s actionable insight you can use to further optimize costs.

Managing and Reducing Operating Expenses

Armed with a solid understanding of your operating expenses, you can start implementing strategies to better manage and optimize them. Every business is different, but here are some general best practices:

1. Create an expense policy: Make sure employees know what is and isn‘t an allowable operating expense. Set clear guidelines around things like travel, meals, and office supplies.

2. Negotiate with vendors: Don‘t be afraid to shop around for better deals on recurring operating costs. Regularly renegotiate contracts for things like insurance, telecommunications, and equipment leases.

3. Embrace automation: Look for opportunities to use technology to reduce manual workflows. For example, using chatbots on your website can decrease customer service labor costs.

4. Outsource strategically: Partnering with third-party experts for ancillary business functions like accounting, IT, or marketing can reduce the cost of in-house staff. Just be sure to vet providers carefully.

5. Optimize your space: Real estate is a huge operating expense. Consider downsizing office space, subletting extra capacity, or shifting to a virtual workforce to save on rent and utilities.

6. Go paperless: Transitioning away from physical mail, faxes, and checks can significantly reduce spend on office supplies, postage, and bank fees. Aim to digitize wherever you can.

When considering cost-cutting measures, always think in terms of ROI. Reducing operating expenses is good, but not if it comes at the expense of quality, employee morale, or customer experience. For example, let‘s say you spend $5,000 per month on free coffee and snacks for the office. Cutting that perk would save $60,000 per year. But if it causes a 5% dip in productivity from a disgruntled staff, it‘s probably not worth it, especially if that lost output is greater than the cost savings.

The Tax Impact of Operating Expenses

It‘s also important to understand how operating expenses impact your tax situation. Most operating costs are tax-deductible, meaning you can subtract them from your revenue when calculating taxable income. This effectively lowers your tax bill, making it even more advantageous to carefully track operating expenses.

However, not all costs can be deducted right away. Some larger expenditures, like computers and equipment, must be capitalized and expensed over time through depreciation. And if you later sell a depreciated operating asset for more than its book value, you may have to pay tax on depreciation recapture.

Budgeting for Operating Expenses

Finally, it‘s critical to budget for operating expenses as part of your overall business planning process. A solid operating budget should be based on historical expense data, adjusted for factors like inflation, business growth, and upcoming projects.

Review your operating expense budget regularly throughout the year. Investigate any major variances between budgeted and actual costs. The variance could indicate an problem, like an unaccounted for cost increase. Or it might represent an opportunity, like a vendor who came in under budget. Either way, staying on top of budget vs actuals is an important way to keep operating expenses under control.

Your operating expense budget should evolve along with your business. As you grow and mature, what made sense for a lean startup might not be appropriate for a more established organization. Be sure to revisit your assumptions and projections at least annually to account for changing circumstances.

The Bottom Line on Operating Expenses

We‘ve covered a lot of ground in this crash course on operating expenses. To recap, here are the key takeaways:

1. Operating expenses are the costs incurred to run the day-to-day operations of a business, not including cost of goods sold.
2. Tracking operating expenses and comparing to revenue is critical for understanding and improving profitability.
3. Operating costs are typically split into fixed, variable, and semi-variable categories.
4. The operating expense ratio reveals how much of each dollar earned is consumed by operating costs. Lower is generally better.
5. Benchmarking operating expenses against past performance, industry averages, and competitors provides valuable context for improvement.
6. There are many strategies to reduce operating expenses, but always consider the ROI and potential impact to the business.
7. Most operating costs are tax-deductible expenses, with some caveats around depreciation and capitalization rules.
8. Budgeting for operating costs and regularly reviewing actual vs. budget is an important cost control method.

Understanding and optimizing operating expenses is an ongoing process. But with diligent accounting, analysis, and a focus on efficiency, you can keep your operating costs under control and position your business for long-term profitability and success.
