📖 What it is

The Operating Calculator helps you assess your business's core profitability by calculating operating income and margin, which are crucial for financial health.

You simply need to input your total revenue, cost of goods sold (COGS), and operating expenses. The output will reveal your operating income and margin, critical metrics for evaluating performance.

Keep in mind that this tool focuses solely on operating activities, so it should not be used to gauge overall profitability when financing and tax considerations come into play.

How to use

  1. Identify your total revenue.
  2. Determine your Cost of Goods Sold (COGS).
  3. Calculate your operating expenses.
  4. Use the formula: Operating Income = Revenue - COGS - Operating Expenses.
  5. Calculate Operating Margin = (Operating Income / Revenue) * 100.

📐 Formulas

  • Operating Income—Operating Income = Revenue - COGS - Operating Expenses
  • Operating Margin—Operating Margin = (Operating Income / Revenue) * 100

💡 Example

Assume your total revenue is $50,000.

Cost of Goods Sold (COGS) is $28,000, and Operating Expenses are $12,000.

Using the Operating Calculator:

Operating Income = $50,000 - $28,000 - $12,000 = $10,000.

Operating Margin = ($10,000 / $50,000) * 100 = 20%.
