Operating Expense Ratio Formula

Formula
$$\text{Operating Expense Ratio} = \frac{\text{Operating Expenses}}{\text{Net Revenue}} \times 100$$

Explanation:
The OER measures how efficiently a company uses its revenue to cover operating costs. A lower ratio indicates higher efficiency, while a higher ratio may suggest cost management issues.

The Operating Expense Ratio is widely used in real estate, corporate finance, and budgeting to evaluate financial performance. It helps stakeholders understand how much income is consumed by regular business operations — excluding taxes, interest, or capital costs.

Example Variables:

  • Operating Expenses: $400,000
  • Net Revenue: $1,000,000
  • OER = (400,000 / 1,000,000) × 100 = 40%

Use Cases:

  • Budget analysis for startups and SMEs
  • Real estate property management
  • Financial efficiency tracking in large organizations
