Gross income is a crucial financial term that reflects the total earnings of an individual or a business before any deductions or taxes are applied. 

• For Individuals: It includes all sources of income such as wages, salaries, bonuses, rental income, pension, dividends, and interest income, before any taxes or deductions.
• For Businesses: Also known as gross profit or gross margin, it is the total revenue minus the cost of goods sold (COGS). It gives an insight into the profitability of the company's core business activities.

Calculating Gross Income for Individuals

• Add Up All Sources of Income: This includes salary, hourly wages, bonuses, dividends, interest income, rental income, pension, and any other income sources.
• Consider the Pay Period: For accurate calculation, consider the pay period whether it’s weekly, bi-weekly, or monthly.
• Use Year-End Tax Documents: Gross income can also be found on year-end tax documents like W-2 or 1099 forms.

Gross Income vs. Net Income

Individual Net Income: This is what remains after subtracting all deductions (taxes, health insurance, retirement contributions) from the gross income. It’s the actual take-home pay.

Business Net Income: It’s calculated by subtracting all operating expenses, taxes, interest, and other expenses from gross income. It indicates the actual profitability of the business after all costs.

Calculating Gross Income for Businesses

• Formula: Gross Income = Total Revenue - COGS.
• COGS: Includes all direct costs associated with producing goods or services sold by the business. It does not account for indirect expenses like marketing or sales costs.
• Time Period: Businesses often calculate gross income annually, but it can also be done quarterly or monthly.

Monthly Gross Income Calculation

• For Individuals: Gross monthly income is your income per month before deductions. It can be calculated by dividing the annual salary by 12 or multiplying the hourly rate by the number of working hours in a month.
• For Businesses: The same formula (Total Revenue - COGS) is used, but with figures calculated on a monthly basis.

Importance of Gross Income

• Taxation: It's the starting point for determining taxable income on tax returns after factoring in deductions and exemptions.
• Financial Planning: For individuals, understanding gross income is crucial for budgeting and financial planning.
• Business Analysis: For businesses, it helps in evaluating the performance of core operations and making strategic decisions.

Non-Taxable Income

Certain types of income, like inheritances, municipal or state bonds, social security benefits, and life insurance proceeds, are usually not included in the taxable gross income.
