Monthly income calculator: convert any pay period to monthly
Monthly income is your gross pay expressed over a 30 or 31-day month, before any taxes or deductions. A $60,000 annual salary works out to $5,000 per month gross. A $20 per hour wage at 40 hours per week is $3,467 per month. The math is one multiplication and one division — the trick is the multiplier in the middle, especially when the input is biweekly.
The calculator at the top of this page accepts any pay period and shows the monthly figure highlighted in dark, with every other period below for sanity-checking. The article maps out the formulas, the biweekly trap that costs renters and borrowers thousands per year, and where typical US monthly incomes actually sit.
What is monthly income?
Monthly income is the total amount earned in a calendar month, before tax. Mortgage lenders, landlords, and credit card issuers ask for monthly income because the bills they care about (rent, mortgage payments, credit card minimums) are monthly. Annual figures get converted at the door.
"Gross monthly income" is what almost every form on this page asks for. Net (take-home) monthly income is what actually arrives in the bank account after federal tax, state tax, Social Security, Medicare, and benefits. The gap between them depends on the state, the filing status, and the benefits package.
The monthly income formula
Monthly income is annual income divided by 12. To get there from a different pay period, multiply pay by the corresponding period multiplier, then divide by 12.
Annual ÷ 12 Quarterly ÷ 3Semi-monthly × 2 Biweekly × 26 ÷ 12Weekly × 52 ÷ 12 Daily × 260 ÷ 12Hourly × hours/wk × 52 ÷ 12 (at 40 h/wk: × 173.33)The number 173.33 is worth memorizing if you negotiate hourly. It is 2,080 hours per year ÷ 12 months. Multiply any hourly rate by 173.33 and you get gross monthly income at 40 hours per week.
Hourly to monthly income
The most-searched conversion on this page. Multiply the hourly wage by 173.33 (which is 40 hours × 52 weeks ÷ 12 months) and you have the gross monthly income.
- $7.25/hr = $1,257/mo (US federal minimum wage)
- $10/hr = $1,733/mo
- $15/hr = $2,600/mo
- $18/hr = $3,120/mo
- $20/hr = $3,467/mo
- $25/hr = $4,333/mo
- $30/hr = $5,200/mo (about the US median full-time wage)
- $40/hr = $6,933/mo
- $50/hr = $8,667/mo
Part-time changes the answer. At 30 hours per week, $20/hr is $2,600 per month, not $3,467. The calculator's hours-per-week selector adjusts the multiplier directly.
Months are not 4 weeks. A common shortcut, hourly × 4 × 40 = hourly × 160, gives a number that is 8% too low. The correct multiplier is 173.33, derived from 52 weeks ÷ 12 months × 40 hours. The 13.33-hour gap reflects the fact that the average month is 4.33 weeks, not 4.
Biweekly vs. semi-monthly pay
This is the most common confusion in US payroll, and it produces real budgeting errors month after month. The words sound nearly identical. The numbers are not.
Biweekly means every 14 days. The paycheck always arrives 14 days after the last one, no matter where that falls in the month. Across a year that lands 26 times. Two months a year include three biweekly checks instead of two.
Semi-monthly means twice per month, usually on the 1st and 15th. That is 24 paychecks per year, exactly two each month. Same annual total can produce different paycheck sizes: at $60,000 annual, a biweekly check is $2,308 and a semi-monthly check is $2,500.
To convert biweekly to monthly, multiply by 26 then divide by 12 — not by 2. A $2,308 biweekly paycheck is $5,001 per month on average, not $4,616.
Many budgeting templates assume biweekly × 2 = monthly. That formula gives $4,616 per month on a $2,308 biweekly check — but the real average is $5,001. The math undercounts the two annual "third-paycheck" months. Result: over 12 months you end up with about $5,000 of "surplus" you did not plan for. Budget monthly using biweekly × 26 ÷ 12.
Gross vs. net monthly income
Every figure produced by this calculator is gross — pre-tax. Net monthly income is what actually hits the bank account after withholding. The gap is rarely small.
On a $5,000 gross monthly income ($60K annual), expect roughly $1,000 to $1,600 of monthly deductions. Federal income tax takes about $420 to $670 per month depending on bracket and filing status. Social Security takes 6.2%, or $310 per month. Medicare takes 1.45%, or $73. State income tax ranges from 0% (Texas, Florida, Washington, Nevada, Tennessee, Wyoming, South Dakota, Alaska, and New Hampshire on wages) to over 13% (California). Health insurance, 401(k), and HSA contributions come out separately.
Net monthly income for a $60K earner in a no-income-tax state is typically around $4,000 to $4,200. In California or New York, the same earner nets closer to $3,600 to $3,800. The take-home percentage on gross monthly income lands between 65% and 80% depending on state and benefits load.
Median monthly income in the United States
For context on where the calculator's outputs land, the most recent US Census Bureau and BLS figures:
- $5,165/mo median individual full-time earnings ($61,984 annual, BLS Q4 2024)
- $6,978/mo median US household income ($83,730 annual, US Census 2024)
- $5,660/mo mean occupational wage ($67,920 annual, BLS OEWS)
- $4,125/mo median occupational wage ($49,504 annual, BLS OEWS)
- $1,257/mo federal minimum-wage monthly equivalent ($7.25 × 173.33)
- ~$8,042/mo median "financial comfort" threshold per Federal Reserve SHED 2023
The Federal Reserve's Survey of Household Economics and Decisionmaking found that the median respondent reported needing about $96,500 per year — roughly $8,042 per month — to feel financially comfortable. That is about 15% above actual median household income. The gap between "getting by" and "comfortable" lands at roughly $1,000 per month of additional income.
Monthly income for rent and mortgages
The most common downstream use of a monthly income number is qualifying for housing. Most US landlords apply the 3× rule: gross monthly income should be at least three times the monthly rent. At $1,500 rent, that requires $4,500 monthly ($54,000 annual). At $2,000 rent, $6,000 monthly ($72,000 annual). Some New York and high-cost markets push the multiplier to 40× or 50× the monthly rent.
Mortgage lenders use debt-to-income (DTI) ratios. The federal QM (Qualified Mortgage) standard caps total DTI at 43% of gross monthly income, though FHA and VA allow higher. At $5,000 gross monthly, the QM cap allows $2,150 in total monthly debt payments — mortgage, car loans, credit cards, and student loans combined.
Both rent and mortgage qualifiers reference gross monthly income, not net. That is why this calculator outputs gross by default. Net is for personal budgeting; gross is for the bank and the landlord.
Common monthly-income mistakes
Multiplying biweekly by 2. 26 paychecks per year, not 24. Two months a year include a third biweekly check. Correct formula: biweekly × 26 ÷ 12, or biweekly × 2.167.
Using hourly × 160 for monthly. A month is 4.33 weeks on average, not 4. Use hourly × 173.33 instead. The 8% gap shows up immediately when comparing job offers.
Confusing gross with net. Landlords, lenders, and benefit programs almost always reference gross monthly income. Pay stubs and bank deposits show net. Knowing which one the conversation calls for matters more than the math.
Forgetting irregular income. Annual bonuses, sales commissions, freelance retainers, and overtime are not spread evenly across months. The calculator's monthly average is correct in aggregate, but month-by-month cash flow can be lumpy.
If your job pays biweekly and you have monthly bills, set automatic transfers of biweekly × 2 into a "monthly bills" account, then use the two extra biweekly checks per year (months with three paychecks) to build an emergency fund or pay down debt. It converts a budgeting hazard into a savings rhythm.
