How to Calculate Gross Monthly Income

Gross monthly income represents the total earnings an individual receives in a month before any deductions are subtracted. This figure provides a comprehensive overview of one’s financial resources, serving as a foundational metric in various financial assessments. It is commonly used when applying for loans, such as mortgages or car loans, where lenders evaluate an applicant’s capacity to repay debt. Understanding gross monthly income also aids in personal budgeting and evaluating overall financial health.

Components of Gross Monthly Income

Gross monthly income encompasses a wide array of earnings from diverse sources, reflecting all money received before taxes and other withholdings. Wages, salaries, and tips earned from employment are primary components, calculated prior to any federal or state income taxes, Social Security, or Medicare deductions. This includes regular pay as well as any overtime worked.

Commissions and bonuses are also included in gross income, as they represent additional earnings tied to performance or company results. For individuals who are self-employed, gross receipts from their business activities count towards gross income before any business expenses are deducted. Rental income collected from properties owned is another component, considered before accounting for property-related expenses.

Other common sources that contribute to gross monthly income include:
Alimony or spousal support.
Social Security benefits.
Distributions from pensions or retirement accounts.
Investment income, such as interest and dividends.

Calculating Gross Monthly Income

Calculating gross monthly income involves aggregating all identified income streams and converting them to a consistent monthly figure. For those with an annual salary, divide the total annual salary by 12. For example, an individual earning $60,000 per year would have a gross monthly income of $5,000.

If paid bi-weekly, meaning 26 paychecks per year, multiply the gross amount per paycheck by 26, then divide the result by 12. For semi-monthly pay, where income is received twice a month, typically on fixed dates, multiply the gross amount per paycheck by 24, then divide by 12. Individuals paid weekly should multiply their gross weekly pay by 52, then divide by 12 to annualize and then monthly.

For hourly workers, determine the average weekly hours worked and multiply that by the hourly wage to find the weekly gross pay. Then, multiply the weekly gross pay by 52 to get the annual income, and finally, divide by 12 for the monthly figure. Summing all these converted monthly amounts from every income source provides the total gross monthly income.

Addressing Variable or Irregular Income

Income that fluctuates, such as earnings from freelance work, seasonal employment, or commissions, requires an averaging method to determine a representative gross monthly figure. Financial institutions often prefer to see a history of this income, typically requiring documentation for at least 12 to 24 months, to assess its stability and likelihood of continuing. This historical review helps to smooth out temporary highs and lows, providing a more reliable estimate of earning potential.

To calculate an average for variable income, sum the total gross income received over a specific period, such as the past 6 to 12 months, and then divide by the number of months in that period. For instance, if a freelancer earned $15,000 over the last six months, their average monthly income would be $2,500. For mortgage applications, lenders often look at the past two years of tax returns or W-2s to calculate an average, particularly for commission-based or bonus income.

One-time payments, such as sporadic large bonuses or infrequent windfalls, are generally treated differently. While they contribute to overall gross income in the period received, they are often excluded from the calculation of a consistent gross monthly income for loan qualification purposes unless there is a clear history of their regular receipt. If a bonus is consistently received annually, it may be annualized by dividing the bonus amount by 12 and adding it to the monthly income.
