Operating Expense Calculator
Every business incurs costs to keep its operations running. Whether it’s paying rent, utilities, salaries, or advertising, these are collectively referred to as Operating Expenses. Keeping a close eye on them is crucial for maintaining profitability and planning future growth. That’s where our Operating Expense Calculator comes in—helping you easily track and calculate these costs for better financial management.
What Are Operating Expenses?
Operating Expenses (OPEX) are the day-to-day expenses required to run a business. These include:
- Rent or lease payments
- Utilities
- Office supplies
- Salaries and wages (excluding production staff)
- Marketing and advertising
- Insurance
- Depreciation
- Maintenance
They do not include the Cost of Goods Sold (COGS) or capital expenditures, which are separate in financial reporting.
Formula
The basic formula for calculating total operating expenses is:
Operating Expenses = Selling Expenses + General & Administrative Expenses
Where:
- Selling Expenses include advertising, sales commissions, distribution, etc.
- General & Administrative (G&A) Expenses include rent, salaries, utilities, insurance, etc.
How to Use the Operating Expense Calculator
Using the calculator is straightforward:

Example
Let’s say you want to calculate your monthly operating expenses:
- Selling Expenses: $8,000
- G&A Expenses: $12,000
Operating Expenses = $8,000 + $12,000 = $20,000
In this case, your business’s operating expenses for the month would be $20,000.
