What Is Gross Monthly Income? (And How To Calculate It)
What Does Gross Monthly Income Mean?
For an employee, gross monthly income generally begins with gross pay—the amount earned before payroll deductions. Depending on the purpose of the calculation, it may also include other regular sources of income.
Potential income sources include:
- Salary or hourly wages
- Overtime
- Bonuses
- Commissions
- Tips
- Freelance or contract earnings
- Investment income
- Rental income
- Certain benefits or payments
- Income from a side business
The IRS states that compensation for personal services generally includes wages, salaries, commissions, fees and tips. However, a lender or housing provider may use its own rules when determining which income sources it accepts.
Gross Monthly Income vs. Net Monthly Income
Gross monthly income is calculated before deductions. Net monthly income is the amount remaining after deductions—the money commonly called take-home pay.
Common deductions include:
- Federal income tax
- State and local income taxes
- Social Security and Medicare taxes
- Health insurance premiums
- Retirement contributions
- Flexible spending account contributions
- Wage garnishments
- Voluntary employee benefits
For example, an employee might have a gross monthly income of $5,000 but receive only $3,850 after deductions. The $5,000 figure shows earnings before deductions, while $3,850 represents net monthly pay.
Gross income is useful for comparing earnings and evaluating loan applications. Net income is generally more useful for creating a personal spending plan because it reflects the money actually available.
How To Calculate Gross Monthly Income From an Annual Salary
The standard formula for a salaried employee is:
Gross monthly income = Annual salary ÷ 12
Suppose your annual salary is $72,000:
$72,000 ÷ 12 = $6,000
Your gross monthly income is $6,000 before taxes and payroll deductions.
This formula works even when you are paid every two weeks. A biweekly schedule creates 26 pay periods in a year, but dividing the annual salary by 12 still provides the correct average monthly income.
How To Calculate Gross Monthly Income From Hourly Pay
Hourly employees can use the following formula:
Gross monthly income = Hourly rate × Average weekly hours × 52 ÷ 12
For example, suppose you earn $24 per hour and work an average of 40 hours per week:
$24 × 40 = $960 per week
$960 × 52 = $49,920 per year
$49,920 ÷ 12 = $4,160 per month
Your average gross monthly income is $4,160.
This is an annualized average. The amount on individual monthly pay statements may vary because calendar months contain different numbers of working days and pay periods.
How To Calculate Income With Variable Hours
If your weekly hours change, review several months of pay records and calculate a realistic average.
For example, suppose your gross earnings for the past six months were:
- Month 1: $3,400
- Month 2: $3,750
- Month 3: $3,200
- Month 4: $3,900
- Month 5: $3,550
- Month 6: $3,800
Add the six monthly amounts:
$3,400 + $3,750 + $3,200 + $3,900 + $3,550 + $3,800 = $21,600
Divide the result by six:
$21,600 ÷ 6 = $3,600
Your average gross monthly income is $3,600.
A lender may require a longer history for irregular earnings, seasonal work, commissions or self-employment income.
How To Include Overtime, Bonuses and Commissions
Regular overtime, bonuses and commissions may be included when calculating gross monthly income. The best method depends on whether the income is consistent.
If you received $12,000 in eligible commissions over the past year:
$12,000 ÷ 12 = $1,000 per month
If your monthly salary is $4,500, your combined average becomes:
$4,500 + $1,000 = $5,500
For a one-time bonus, determine the purpose of the calculation before including it. A personal budget might treat the bonus separately, while a lender may average it over a specified period or exclude it without sufficient history.
How To Calculate Gross Monthly Income From Multiple Jobs
Calculate the average monthly income from each job and add the results.
For example:
- Full-time salary: $48,000 ÷ 12 = $4,000
- Part-time earnings: $18 × 10 hours × 52 ÷ 12 = $780
- Average monthly freelance income: $600
Combined gross monthly income:
$4,000 + $780 + $600 = $5,380
Your estimated gross monthly income is $5,380.
Keep supporting records such as pay statements, contracts, invoices and tax documents. An organization may accept only income that can be verified.
How To Calculate Gross Monthly Income When Self-Employed
Self-employed income requires extra care because business revenue is not always the same as personal income.
A freelancer may calculate monthly gross receipts by adding all client payments received during the period. However, lenders and tax authorities may focus on income after allowable business expenses rather than total revenue.
For example, suppose a consultant receives $8,000 in monthly client payments but incurs $2,500 in business expenses. The business has $8,000 in gross receipts, but its income after those expenses is $5,500.
The correct figure depends on the application and accounting method. Self-employed individuals should use the definition requested by the relevant institution and consult a qualified financial or tax professional when necessary.
How Pay Frequency Affects Monthly Income
Pay schedules can make monthly income appear inconsistent even when the annual rate remains unchanged.
Weekly pay
Employees receive 52 checks in a typical year. Some calendar months contain four paydays, while others contain five.
Biweekly pay
Employees receive 26 checks per year. Most months contain two paydays, but two months usually contain three.
Semimonthly pay
Employees receive 24 checks per year, normally on two fixed dates each month.
Monthly pay
Employees receive 12 checks per year.
To calculate an average, use annual gross income divided by 12 instead of multiplying a single paycheck by the number of checks in an ordinary month.
Why Gross Monthly Income Is Important
Loan applications
Lenders may use gross monthly income when assessing whether an applicant can manage a mortgage, car loan or personal loan.
Rental applications
Landlords and property managers often compare gross income with monthly rent. They may request pay statements or employment verification.
Debt-to-income calculations
Debt-to-income ratio compares recurring monthly debt payments with gross monthly income.
The formula is:
Debt-to-income ratio = Monthly debt payments ÷ Gross monthly income × 100
If monthly debt payments total $1,500 and gross monthly income is $5,000:
$1,500 ÷ $5,000 × 100 = 30%
The debt-to-income ratio is 30%.
Salary comparisons
Gross income provides a consistent starting point for comparing job offers. A complete comparison should also consider bonuses, insurance, retirement benefits and taxes.
Financial planning
Tracking both gross and net income helps you understand how much you earn, how much is withheld and how much is available for spending and saving.
Common Gross Monthly Income Calculation Mistakes
Using net pay
Do not use the bank deposit amount when an application asks for gross income. Review the gross-pay line on your pay statement.
Multiplying biweekly pay by two
Multiplying a biweekly paycheck by two understates average monthly income because there are 26 biweekly pay periods, not 24. Multiply by 26 and divide by 12.
Including unreliable income without explanation
Occasional gifts or one-time payments may not qualify as recurring income for a lender. Check the organization’s documentation requirements.
Confusing business revenue with personal income
Self-employed applicants should confirm whether the form requests gross receipts, gross profit, net business income or personal taxable income.
Mixing monthly and annual figures
Convert every source to the same time period before combining the amounts.
