What is Operating Expenses (OpEx)?

The ongoing costs incurred by a business in its day-to-day operations, including rent, salaries, utilities, marketing, and administrative expenses.

How It Works

Operating expenses are the costs required to run the business on a daily basis. They are fully expensed on the income statement in the period incurred (unlike CapEx which is capitalized). OpEx includes: employee salaries and benefits, office rent and utilities, marketing and advertising, insurance premiums, software subscriptions, travel expenses, office supplies, and professional fees. Controlling OpEx is critical for profitability — the operating expense ratio (OpEx ÷ Revenue) shows how efficiently a business converts revenue to profit.

Formula

Operating Expense Ratio = Operating Expenses ÷ Total Revenue × 100

Real-World Example

A company's monthly OpEx: Salaries ₹20,00,000 + Rent ₹3,00,000 + Marketing ₹5,00,000 + Utilities ₹50,000 + Software ₹1,00,000 + Insurance ₹30,000 + Misc ₹1,20,000 = Total OpEx ₹31,00,000 against Revenue of ₹50,00,000. OpEx ratio = 62%.
