Understanding how to calculate gross income is a fundamental skill for both individual and business. It forms the basis for financial assessments, tax computations, and effective budgeting. In this comprehensive guide, we’ll walk you through the essential concepts and instructions to accurately determine your gross income, whether you’re a salaried employee, a business owner, or simply seeking to gain a deeper understanding of your financial situation.

Key takeaways

  • Gross income for an individual consists of income from wages and salary plus other forms of income, including pensions, interest, dividends, and rental income.
  • Gross income for a business is total revenues minus the cost of goods sold.
  • Individual gross income is part of an income tax return and—after certain deductions and exemptions—becomes adjusted gross income, then taxable income.
  • Businesses often use gross income instead of net income to better gauge the product-specific performance of the business.

What is Gross Income?

For individuals, gross income is often referred to as gross pay on paychecks, representing an individual’s total earnings before paying for taxes and other deductions. It encompasses all sources of income, extending beyond cash, and covers property or services received.

Gross income how to calculate?

In the business context, gross income is synonymous with terms like gross margin or gross profit. A company’s gross income, as seen on the income statement, is the revenue from all sources minus the cost of goods sold (COGS).

The Importance of Gross Income

Understanding your gross income is crucial because it serves various purposes that can significantly impact your financial situation, including:

  • Rental Housing: Landlords assess applicants’ gross income to gauge their ability to pay rent.
  • Loan Approval: Lenders use gross income to determine loan eligibility.
  • Tax Calculation: Tax agencies rely on gross income to calculate taxes owed.
  • Salary Negotiations: Job seekers can use their gross income as a basis for salary discussions.
  • Credit Limit: Credit issuers evaluate gross income to establish credit limits.

  • Regular salary
  • Bonuses
  • Commissions
  • Earnings from side jobs
  • Freelance income
  • Extra income
  • Supplemental Security Income (SSI)

Calculate Monthly Gross Income for Individual

If you wonder how to calculate my gross monthly income, here’s the process of determining gross income varies based on the nature of an individual’s income sources:

Salaried Worker

To calculate gross income, simply divide the annual salary by 12 to derive the monthly gross income figure.

Hourly Worker

To calculate your gross monthly income when you’re paid hourly, use this formula:


Gross monthly income = (Hourly pay x Hours worked per week x 52) / 12


Here are the steps for calculating your gross monthly income as an hourly or salaried employee:

  1. Begin by listing all your income sources, such as from pay stubs or other records. Make sure to include each income source only once, and consider listing them vertically to make adding the figures easier.
  2. Convert your annual income into a monthly value. If you’re paid hourly, first determine your weekly income by multiplying your hourly pay by the number of hours worked per week (e.g., $15/hour x 40 hours/week = $600/week). Then, multiply your weekly income by the number of weeks you work in a year (e.g., $600/week x 52 weeks = $31,200/year). Finally, divide your annual income by 12 to account for the number of months in a year:

You can also use a computer program with an automated formula to enhance the accuracy of your calculations. Regardless of the method you choose, it’s essential to double-check your results for precision. Including all decimal values instead of rounding can further enhance the accuracy of your calculations.

Calculate Monthly Gross Income For business

The formula for finding gross annual income for a business is subtracting the cost of goods sold from the gross revenue. Follow the step-by-step guidelines below:

  1. Identify the company’s yearly revenue by checking records or seeking input from management or financial experts who can access this information quickly.
  2. Determine the cost of sales, which may involve services provided or goods sold, and subtract it from the annual revenue. Collaborate with auditors, accounting professionals, and relevant departments to gather accurate figures. This subtraction yields the company’s gross annual income.
  3. Convert the gross annual income into a monthly value by dividing it by 12, giving the average monthly gross income using the equation:


Gross monthly income = Gross annual income / 12

Gross Income vs Net Income. What’s the Difference?

Gross income and net income are terms often used by businesses to indicate profit. They are also relevant when discussing a household’s earnings.

For an individual, net income is the the total amount of money earned after subtracting all the taxes and deductions applicable from the gross income. An individual’s net income aligns closely with their final paycheck; although the paycheck doesn’t cover all expenses, it’s a clear illustration of revenue reduced by costs.

Net Income = Gross Income – Taxes – Other deductions (garnishment, health insurance, retirement plan, job-related expenses, etc.)

For a business, net income is the total amount of revenue minus all the costs. These expenses include the cost of goods sold just like gross income. However, net income also includes selling, general, administrative, tax, interest, and other expenses not included in the calculation of gross income.

What is Adjusted Gross Income (AGI)?

Adjusted Gross Income (AGI) is the amount you get after subtracting specific deductions from your total income. These deductions include things like contributions to retirement accounts or student loan interest. AGI is a crucial starting point for figuring out your taxable income, which is the amount of your income that is subject to taxes. It’s also important for determining your eligibility for certain tax credits and deductions. When you e-file your taxes, your previous year’s AGI is used as a verification measure.

What is Modified Adjusted Gross Income (MAGI)?

Modified Adjusted Gross Income (MAGI) builds on AGI by making additional adjustments based on specific tax benefits and contributions you might be eligible for. It’s a flexible calculation tailored to your financial situation. MAGI helps determine your eligibility for things like tax deductions, credits, and contributions to accounts like health savings accounts (HSAs) and retirement plans. Essentially, MAGI refines the AGI calculation to fit individual financial scenarios and ensure accurate tax benefits.


In conclusion, knowing how to calculate gross income empowers individuals to budget effectively, businesses to assess their revenue streams, and everyone to grasp the essentials of financial planning. It’s a foundational concept that unlocks a deeper understanding of economic well-being and helps guide smart financial choices.


Why is Gross Income Important for Tax Purposes?

Gross income is crucial for tax purposes because it serves as the starting point for determining how much of your income is subject to taxation. When you file your taxes, you start with your gross income and then apply various deductions and exemptions to arrive at your taxable income. This process helps determine the amount of income on which you owe taxes to federal and state governments. Understanding your gross income is essential for accurate tax calculations, eligibility for specific tax credits, and compliance with tax laws.

Do Self-Employed Individuals Calculate Gross Pay Differently?

Yes, self-employed individuals typically calculate gross income differently than traditional employees. For employees, gross income is usually the total amount earned before taxes and deductions. However, self-employed individuals must account for both their business income and the business expenses associated with generating that income. Their gross income is determined by subtracting business expenses from their total business revenue. This approach ensures that the income is calculated based on the actual profit the business generates, rather than the gross revenue alone.

Are Bonuses Included in Gross Income?

Yes, bonuses are generally included in gross income. Bonuses, like regular salary or wages, are a form of compensation received for work performed, and they contribute to an individual’s overall earnings. When calculating gross income for tax purposes, bonuses are added to the total income from all sources, which includes salary, hourly wages, rental income, dividends, and other forms of earned income. The total gross income serves as the starting point for tax calculations, determining taxable income, and eligibility for tax benefits.
