Operating Profit = Operating Revenue - COGS - Operating Expenses - Depreciation & Amortization
Investopedia explains 'Operating Profit'
For example, suppose ABC Printing Company earns $50 million from its core printing related operations, $10 million from its 40% stake in XYZ Corp. and $3.5 million from interest earned in its money market and bank accounts. In addition, the company spends $10 million in production related costs.
Overall, the company's operating profit is $40 million. This is calculated as the $50 million in operating revenue million minus the $10 million in production costs. The other $10 million and $3.5 million in earnings are not included in operating income because they are investment income.
