How To Calculate Gross Monthly Income in 2026
Learning how to calculate gross monthly income is one of those small money skills that quietly controls big decisions. Lenders typically want your housing costs to stay under 28 percent of it, and landlords usually want to see monthly income that’s at least three times the rent. Get the number wrong and you either overshoot your budget or get turned down for something you could actually afford. The good news: the math is simple once you know which number goes where.
I spend my days helping people turn unused household items into cash, so I see how often “income” is bigger than people think once they count everything. This guide breaks down how to calculate gross monthly income from any pay setup, how it differs from take-home pay, why it matters for rent and loans, and how to fold in side income the right way. No jargon, just the formulas and real examples.
What is gross monthly income?
Gross monthly income is the total money you earn in a month before any taxes or deductions are taken out. It’s the top-line number, not what lands in your bank account.
That distinction matters more than people realize. Your gross figure includes your base pay plus overtime, bonuses, commissions, tips, and any regular side income. What it does not include is what gets subtracted later: federal and state taxes, Social Security and Medicare, health insurance premiums, and retirement contributions. Those come out to give you net income, which we’ll cover below.
When a lender or landlord asks for your income, they almost always mean gross. So that’s the number worth calculating correctly first.
How to calculate gross monthly income from a salary
If you earn a fixed annual salary, divide it by 12. That’s your gross monthly income.
Say you earn $60,000 a year. Divide by 12 and your gross monthly income is $5,000. That’s it. The formula is:
Annual salary ÷ 12 = gross monthly income
A few salaried people get paid biweekly (26 paychecks a year) and confuse themselves by multiplying a paycheck by 2. Don’t. Two biweekly checks don’t equal a month, because some months have three pay periods. Always work from the annual figure and divide by 12 for a clean monthly number.
If you earn regular bonuses or commissions, fold them in too. Add your expected annual bonus and typical commission to your base salary, then divide the whole thing by 12. For example, a $60,000 base with a reliable $6,000 annual bonus works out to $66,000, or $5,500 in gross monthly income. Just be conservative with numbers that swing, since a bonus you might not get shouldn’t inflate a figure you plan around.
How to calculate gross monthly income from an hourly wage
For hourly work, multiply your hourly rate by the hours you work per week, then multiply by 52 weeks, then divide by 12 months.
The formula is:
(Hourly rate × hours per week × 52) ÷ 12 = gross monthly income
Here’s a real example. You make $22 an hour and work 40 hours a week. Multiply $22 by 40 to get $880 a week. Multiply $880 by 52 weeks to get $45,760 a year. Divide by 12 and your gross monthly income is about $3,813.
If your hours swing week to week, use a realistic average, not your best week. For income that varies, lenders often average the last few months anyway, so honest numbers serve you better than optimistic ones.
How to calculate gross monthly income when you’re self-employed
For freelancers, contractors, and business owners, gross monthly income is your total revenue minus business expenses, averaged across the year.
Add up everything your business brought in over the last 12 months, subtract your legitimate business costs (supplies, software, mileage, fees), and divide by 12. That’s the number lenders will work from, and it’s usually what shows on your Schedule C. Self-employed income is bumpy, so a 12-month average smooths out the good and slow months into a figure you can actually plan around.
If a chunk of your income comes from reselling, flipping, or side gigs, it counts too, as long as it’s steady and documented. Our guide on how much you can make reselling furniture shows how real that side income can get.
Gross vs net income: know the difference
Gross income is what you earn. Net income is what you keep. Confusing the two is the most common budgeting mistake there is.
Your net income (take-home pay) is your gross minus taxes and deductions. For most workers, net lands somewhere between 70 and 85 percent of gross, depending on your tax bracket, state, and benefits. Here’s how the two compare in practice:
| Factor | Gross monthly income | Net monthly income |
|---|---|---|
| What it means | Total earned before deductions | Take-home pay after deductions |
| Includes taxes? | Yes, taxes not yet removed | No, taxes already removed |
| Used for | Loan and rent applications, DTI ratios | Day-to-day budgeting and spending |
| Example on $60k salary | $5,000 | Roughly $3,800 to $4,100 |
Rule of thumb: use gross when someone else is evaluating you, and use net when you’re planning your own spending. Budget off the money that actually hits your account, not the bigger number on your offer letter.
Why your gross monthly income matters
Gross monthly income is the single number that decides what you qualify for. It drives three big things.
- Renting an apartment. Most landlords want gross monthly income of at least three times the rent. On $1,500 rent, that’s $4,500 a month.
- Getting a mortgage. Lenders use your debt-to-income ratio, which compares monthly debt payments to gross monthly income. Most want total debt under 36 to 43 percent of gross.
- Qualifying for loans and cards. Auto loans, personal loans, and credit limits all key off gross income to gauge what you can repay.
Because these decisions all lean on gross, it pays to count every legitimate source, including consistent side income. A few hundred extra dollars a month can move you into a better rate or a bigger approval.
How to include side income in your gross monthly income
Side income counts toward gross monthly income when it’s regular and you can document it. That includes freelance work, gig platforms, rental income, and steady resale earnings.
The key word is documented. A one-time garage sale won’t help you on a mortgage application, but consistent monthly earnings from selling items, driving, or freelancing will, especially with a paper trail like deposits or 1099s. If you’ve been meaning to turn clutter into a real income stream, our roundups of side hustle jobs and ways to make money from home are good starting points, and how to make extra money covers the fastest options.
One of the simplest ways to add to your monthly income is selling the big stuff sitting unused around your house. A treadmill, a sofa, a hot tub, an old appliance. These hold real resale value, but people avoid selling them because they’re a pain to move. On Commonplace, drivers handle the pickup, buyers and sellers never meet, and payment comes to you at pickup, so the heavy items finally turn into cash instead of clutter. Here’s how it works, and if you want to price things right first, read how to price used items to sell.
Frequently asked questions
How do I calculate my gross monthly income?
For a salary, divide your annual pay by 12. For hourly work, multiply your hourly rate by hours per week by 52, then divide by 12. For self-employment, average your last 12 months of revenue minus business expenses. Add any regular, documented side income to the total.
Is gross monthly income before or after taxes?
Before taxes. Gross monthly income is your total earnings before any taxes, insurance, or retirement deductions are taken out. The amount after those deductions is your net income, or take-home pay.
What is the gross monthly income for a $60,000 salary?
$5,000. Divide the $60,000 annual salary by 12 months to get a gross monthly income of $5,000 before taxes and deductions.
Does side income count toward gross monthly income?
Yes, as long as it’s regular and documented. Steady freelance work, gig earnings, rental income, and consistent resale income all count. One-time windfalls generally do not count for loan or rental applications.
Why do lenders ask for gross instead of net income?
Gross income is a standardized figure that doesn’t change with your personal deductions or benefit choices, so it lets lenders compare applicants fairly and calculate debt-to-income ratios consistently.
Get your number right, then grow it
Calculating gross monthly income comes down to one formula for your pay type plus every legitimate source added on top. Salary divided by 12, hourly annualized then divided by 12, or self-employment averaged across the year. Keep gross and net straight, and use the right one for the job.
Once you know your number, the fastest way to move it is adding income you already have sitting around. If you’ve got big unused items taking up space, list them on Commonplace and let the drivers handle pickup while you collect the payment. And if you’re furnishing a place on a budget you just calculated, browse inspected, tested used items with a 60-minute in-home test before you pay. Either way, a clear income number makes every next decision easier.
