How to Figure Out How Much You Make a Month
Calculating Monthly Income from Hourly Wages
Knowing your monthly income is one of the most useful numbers in your financial life. Lenders check it before approving a mortgage. Landlords use it to decide whether you can afford the rent. And it’s the starting point for every budget you’ll ever build.
The tricky part is that the formula changes depending on how you’re paid. This guide walks through every pay type — hourly, salary, weekly, biweekly, semimonthly, daily, and self-employed — so you can find your exact number in seconds.
- Gross monthly income is your total earnings before taxes and deductions.
- Salaried: Annual salary ÷ 12
- Hourly: Hourly rate × hours per week × 52 ÷ 12
- Weekly paycheck: Weekly pay × 4.333 (or × 52 ÷ 12)
- Biweekly paycheck: Biweekly pay × 2.1667 (or × 26 ÷ 12)
- Semimonthly paycheck: Paycheck amount × 2 (24 checks/year, on fixed dates)
- Self-employed: Total income from the last 12 months ÷ 12
- Your gross pay is printed directly on your pay stub, W-2, or offer letter — you don’t always have to calculate it.
What Is Gross Monthly Income?
Gross monthly income is the total amount you earn in a single month before any taxes or deductions come out. It includes:
- Regular wages or salary
- Overtime pay
- Bonuses and commissions
- Freelance or side-job earnings
- Investment income, if applicable
For example, if your salary pays you $3,000 a month and you earn another $500 from a side gig, your gross monthly income for that month is $3,500. Lenders, landlords, and government programs almost always ask for this gross figure — not your take-home pay — because it reflects your full earning capacity before any voluntary deductions
How to Calculate Monthly Income by Pay Type
If You're Paid an Annual Salary
The simplest case. Your employer already sets a fixed yearly number.
Formula: Annual salary ÷ 12
Example: A $60,000 salary ÷ 12 = $5,000 per month (gross, before taxes).
Note: If your salary changed partway through the year, use your current rate, not last year's total.
If You're Paid Hourly
Hourly pay needs an extra step because you can't just divide by 12 — you have to annualize it first using all 52 weeks of the year.
Formula: Hourly rate × hours per week × 52 ÷ 12
Example ($20/hour, 40 hours/week):
$20 × 40 = $800/week → $800 × 52 = $41,600/year → $41,600 ÷ 12 = $3,466.67/month
Use your regular scheduled hours, not occasional overtime. If your hours change week to week, skip to the variable-income section below.
If You're Paid Weekly
Common Mistake: Multiplying your weekly pay by 4 is wrong — there are 52 weeks in a year, not 48, so this shortcut underestimates your real income by roughly $75–$100 a month.
Formula: Weekly pay × 52 ÷ 12 (Quick shortcut: Weekly pay × 4.333)
Example: $900/week × 52 ÷ 12 = $3,900/month
If You're Paid Biweekly (Every Two Weeks)
Biweekly means 26 paychecks a year — not 24. Two months out of every year bring a third paycheck, since 26 doesn't divide evenly across 12 months.
Formula: Biweekly paycheck × 26 ÷ 12 (Quick shortcut: Biweekly paycheck × 2.1667)
Example: $1,600 × 26 ÷ 12 = $3,466.67/month
Never multiply your biweekly check by 2 alone — that gives you a lower, incorrect figure.
If You're Paid Semimonthly (Twice a Month, Fixed Dates)
Semimonthly is different from biweekly, even though people mix them up. You're paid on fixed dates — usually the 1st and 15th — giving you exactly 24 paychecks a year, never 26.
Formula: Semimonthly paycheck × 2
Example: $2,500 per paycheck × 2 = $5,000/month
Because semimonthly pay always lands on 24 checks, there's no "extra paycheck month" the way there is with biweekly pay — your monthly figure stays identical every month.
If You're Paid a Daily Rate
Formula: Daily rate × working days in the month
Example: $150/day × 22 working days = $3,300/month
Most months have 21–23 working days (21.7 on average across the year). For an annual estimate, multiply your daily rate by roughly 260 working days, then divide by 12.
If You're Self-Employed or Freelance
Income that changes month to month makes a single formula unreliable. The method mortgage lenders and banks actually use is a 12-month average.
Formula: Total income earned in the last 12 months ÷ 12
Example: $41,000 earned over 12 months ÷ 12 = $3,416.67/month
A few things to know:
- Use your net profit, not total revenue, if you're self-employed.
- For loan applications, lenders typically want two years of tax returns and often average your Schedule C net profit over 24 months, not just 12.
- Some lenders add back non-cash deductions (like depreciation) when calculating your qualifying income.
- If your income is trending upward, some lenders will accept a shorter 3-month average instead.
If You Have Multiple Jobs or Income Sources
Calculate each income source with the formula that matches it, then add them together.
Full-time job
$2,200/month
Part-time job
$700/month
Freelance average
$400/month
Total Gross Monthly Income
$3,300/month
*Include bonuses, overtime, and tips only if they're received regularly — not one-off amounts.
Documents That Already Show Your Monthly Income
You often don't need to calculate anything — the number is already sitting on a document you have.
| Document | Where to Look | Notes |
|---|---|---|
| Pay stub | "Gross Pay" or "Gross Earnings" line | If paid biweekly, multiply by 2.1667 for a monthly figure. |
| W-2 form | Box 1 (Wages, tips, other compensation) | Divide by 12 for your average. Box 1 may be lower than actual gross pay if you make pre-tax 401(k) contributions. |
| Employment offer letter | Stated annual salary | Divide by 12 for a quick gross monthly figure. |
| Year-to-Date (YTD) total on a pay stub | Running total since January 1 | Divide YTD gross pay by the number of months completed in the year. |
YTD Example: A pay stub from the end of June shows YTD Gross Pay of $24,000. Since June is month 6, divide $24,000 ÷ 6 = $4,000/month.
If you have more than one employer or income stream, add each pay stub's gross figure together to get your full monthly total.
What If Your Hours or Income Vary Every Week?
Fixed formulas don't work well if your schedule changes constantly. Two averaging methods handle this accurately:
Quick Method: 4–6 Week Average (for weekly paychecks)
Average your last 4 to 6 weeks of gross pay, then multiply by 4.333 for a monthly figure. This works well for a fast estimate.
More Accurate Method: 13-Week Averaging (for hourly, variable-hours work)
This is the method lenders often trust most, because it covers a full quarter and smooths out slow weeks and overtime spikes.
Formula: Average weekly hours × hourly rate × 52 ÷ 12
Example: Over 13 weeks, your pay stubs show 442 total hours worked.
- 442 ÷ 13 = 34 hours/week average
- At $17/hour: 34 × $17 × 52 ÷ 12 = $2,507.33/month
Documents to Gather Before You Calculate
- Your last 13 consecutive pay stubs (one full quarter)
- Your current employment contract (to confirm your base rate)
- A calculator or spreadsheet to track the numbers cleanly
Gross vs. Net Monthly Income
These are two different numbers, and using the wrong one on an application can cause an otherwise-qualified applicant to get rejected.
| Feature | Gross Monthly Income | Net Monthly Income |
|---|---|---|
| What it means | Total earned before deductions | Amount actually deposited into your bank account |
| Taxes taken out | No | Yes |
| Where to find it | Top of your pay stub or offer letter | Bottom of your pay stub or bank deposit |
| When to use it | Loan applications, rental applications | Personal budgeting, spending plans |
For most people, net income runs 15–30% lower than gross income. According to the FDIC, mortgage lenders typically cap total housing costs at 28% of gross monthly income — always the gross figure, never take-home pay.
Formula: Gross Monthly Income × 0.28 = Maximum Monthly Housing Cost
Example: $4,000 gross monthly income × 0.28 = $1,120 maximum recommended monthly housing cost.
Household and Combined Income
Some applications — especially rental applications and certain government assistance programs — ask for household gross monthly income, meaning every earner in the home combined, not just your individual number.
Example:
- You: $1,100/month (part-time) + $900/month (side business) = $2,000/month
- Your spouse: $3,100/month (full-time job)
- Combined household gross monthly income: $5,100/month
If you’re applying jointly for a lease or a loan, this combined figure — not either person’s individual income — is usually the number that matters.
A Complex Example: Salary + Bonus + Side Income
Regular formulas cover predictable pay, but real life often mixes recurring income with one-time amounts in the same month. Here’s how to combine them correctly.
Scenario: You earn $65,000/year at your full-time job. This month, you also received a $5,000 year-end bonus and made $3,500 from a freelance project.
- Regular monthly salary: $65,000 ÷ 12 = $5,416.67
- Add one-time bonus: + $5,000
- Add freelance income: + $3,500
- Total gross monthly income for this specific month: $13,916.67
Keep in mind: this figure only reflects this month. For an ongoing average (which lenders usually want), you’d only count the bonus and freelance income if they recur regularly — otherwise, report your baseline $5,416.67 as your standard monthly income and disclose the bonus/freelance income separately.
Why Your Monthly Income Number Matters
Loan & Mortgage Applications
Lenders use your gross monthly income to calculate your debt-to-income (DTI) ratio. Most mortgage lenders require DTI below 43%; personal loans typically cap around 35%.
Apartment Rentals
Most landlords require gross monthly income to be at least three times the monthly rent (a $1,500/month apartment generally requires $4,500+ in gross monthly income).
Government Benefits
Programs like SNAP and Medicaid use gross monthly income thresholds to determine eligibility, so knowing this number helps you understand what you may qualify for.
Personal Budgeting
You can't build an accurate budget without a correct monthly income figure.
Tax Filing
Understanding your monthly gross helps estimate quarterly taxes and catch underpayment early.
Salary Negotiation
Converting a job offer into a monthly figure lets you compare it directly against your current income and expenses.
Common Mistakes to Avoid
Multiplying weekly pay by 4 instead of 4.333 — understates monthly income by $75–$100+.
Multiplying biweekly pay by 2 instead of 2.1667 — misses the two "extra paycheck" months each year.
Confusing biweekly with semimonthly — biweekly is 26 checks/year; semimonthly is exactly 24.
Using revenue instead of net profit if you're self-employed.
Ignoring irregular bonuses/overtime when reporting a stable, ongoing monthly income for a loan or lease.
Forgetting that Box 1 on your W-2 may be lower than your true gross pay due to pre-tax 401(k) or health insurance contributions.
Frequently Asked Questions
Average your total hours from the past 13 weeks to find your weekly average. Multiply that by your hourly rate, multiply by 52, and divide by 12.
Official paperwork usually requests your gross monthly income, which is your total earnings before tax deductions. Net monthly income refers to your actual take-home pay after taxes and benefits are removed.
Add your base annual salary to the total bonus amount you earned over the last year. Divide that combined baseline number by 12 to find your true monthly average.
At a standard 40-hour work week, earning $20 an hour brings in $3,466.67 per month in gross income. If you work a 32-hour work week, that same hourly rate equals $2,773.33 per month.
Biweekly schedules result in 26 paychecks a year because workers receive a payout every two weeks. Semi-monthly schedules result in 24 paychecks a year because payouts occur twice a month on fixed dates.
