How do you calculate net profit before tax and extraordinary items?

Net profit before tax and extraordinary items is calculated by taking the total revenue and subtracting the total operating expenses, including cost of goods sold (COGS), selling, general, and administrative expenses. Additionally, any non-operating income and expenses should be excluded, along with extraordinary items like gains or losses from unusual events. The formula can be summarized as: Net Profit Before Tax and Extraordinary Items = Total Revenue - Total Operating Expenses. This figure provides a clearer view of the company's operational performance before the impact of taxes and one-time events.
