What Is Gross Income?

Gross income refers to the total earnings an individual or business receives before taxes and deductions are applied. For individuals, this includes wages, salaries, pensions, interest, dividends, rental income, and even non-cash earnings such as property or services. When shown on a paycheck, it’s commonly called gross pay.

For businesses, gross income—also known as gross margin or gross profit—is calculated by subtracting the cost of goods sold (COGS) from total revenue, providing insight into the profitability of products or services before other expenses.

Key Points to Remember

• Individual gross income includes wages plus other income sources like pensions, dividends, and rental earnings.
• Business gross income equals total revenue minus the cost of goods sold.
• Gross income is the starting figure on tax returns before deductions transform it into adjusted gross income (AGI) and taxable income.
• Lenders and landlords often consider gross income to evaluate loan or rental applications.
• Businesses use gross income to assess product-specific profitability, excluding unrelated expenses like rent.

How Gross Income Functions

Individuals can find their gross income by reviewing pay stubs or calculating wages based on hours worked. For businesses, calculating gross income involves subtracting direct production costs from revenue, which helps isolate product performance and profitability.

Lenders and landlords use individual gross income to assess financial reliability before deducting expenses. For companies, gross income highlights earnings from core operations, excluding administrative and selling costs for clearer analysis.

Calculating Gross Income

For Individuals

Individual gross income encompasses all income types, including wages, tips, dividends, rental income, pensions, and interest. Adjusted gross income (AGI) is derived after subtracting allowable deductions like student loan interest.

Some income sources, such as certain Social Security benefits and life insurance proceeds, may be excluded from tax calculations but considered by lenders when assessing gross income.

For loan applications, individuals typically report total earnings before deductions. Some lenders may request AGI for consistency in evaluation.

For Businesses

Business gross income is calculated as:

Gross Income = Gross Revenue − Cost of Goods Sold (COGS)

This figure, sometimes called gross margin, reveals profit from sales before accounting for operating expenses, taxes, and interest.

Businesses can calculate gross income company-wide or by product to evaluate profitability accurately.

Important Note

Gross income accounts for direct production costs but excludes expenses like administrative fees, marketing, taxes, and other overhead.

Gross Income vs. Net Income

Gross income shows total earnings before deductions, while net income reflects actual take-home pay or profit after all expenses.

For individuals, net income is the amount left after taxes and other deductions, resembling the final paycheck. For businesses, net income includes all costs beyond COGS, such as administrative and tax expenses.

Gross income offers a broad view of earnings, whereas net income provides a complete picture of profitability.

Quick Insight

Gross income helps compare companies by focusing on revenue generation efficiency, making it valuable for assessing performance across industries.

Individual Gross Income Example

Imagine a person earning $75,000 annually, plus $1,000 in interest, $500 in dividends, and $10,000 from rental properties. Their gross income totals $86,500 yearly or about $7,200 monthly.

Expenses like rent, student loans, and car payments do not reduce gross income for loan or rental assessments. For tax purposes, deductions such as $500 in student loan interest lower adjusted gross income to $86,000.

Business Gross Income Example

Apple reported $89.5 billion in net sales for Q3 2023, with $49.08 billion in combined costs of goods sold for products and services. This resulted in a gross income of $40.43 billion.

Additional costs like research and development, administrative expenses, and taxes are excluded from gross income calculations.

Gross vs. Net Income Summary

Net income represents actual earnings after all costs, while gross income focuses on revenue minus direct production costs only.

How to Calculate Business Gross Income

Subtract COGS from gross revenue. For example, if sales are $500,000 and COGS is $100,000, gross income equals $400,000.

Does Gross Income Include Taxes?

Gross income is calculated before taxes or other deductions are applied, representing total earnings prior to expenses.

Final Thoughts

Gross income is a crucial financial metric reflecting total earnings before deductions. Individuals can find this figure on pay stubs or tax forms like W-2 or 1099. Knowing your gross income helps with budgeting, loan applications, and understanding your financial health.

Calculating monthly gross income involves either using your salary before taxes or multiplying hourly wages by hours worked.
