What is Net Income?
Net income is a company’s total profit after subtracting all expenses, taxes, interest, and costs from its total revenue. Often referred to as the “bottom line,” it shows how much money a business actually earns during a given period.
Net income is a key indicator of financial performance, profitability, and operational efficiency. It appears on the income statement and is used extensively by investors, lenders, and analysts.
Definition
Net income is the profit a company earns after deducting all expenses (including operating costs, interest, taxes, and depreciation) from total revenue.
Key takeaways
- Bottom-line metric: Reflects a company’s final profit after all deductions.
- Appears on the income statement: One of the most important financial reporting figures.
- Used by investors: Helps assess profitability, valuation, and return potential.
- Can be distributed or reinvested: Companies may pay dividends or retain earnings for growth.
- Affected by accounting policies: Depreciation, write-downs, and tax strategies influence net income.
How net income is calculated
Formula:
Net Income = Total Revenue – Total Expenses
where expenses may include:
- Cost of goods sold (COGS)
- Operating expenses
- Interest expenses
- Taxes
- Depreciation and amortization
- Extraordinary or one-time charges
Example:
A company generates $1,000,000 in revenue and has $850,000 in total expenses.
Net Income = 1,000,000 – 850,000 = $150,000
