Net income is what you actually take home after taxes and deductions come out of your gross pay

Your net income is the money left in your account after your employer or your business subtracts taxes, Social Security, Medicare, health insurance premiums, retirement contributions, and any other deductions. It is not the same as your salary or hourly wage — that number is your gross income. The difference between gross and net can be 20 to 40 percent of your paycheck, depending on where you live, your tax bracket, and what deductions you have chosen.

Understanding how net income works matters because it is the actual amount you budget with. When you see a job posting that says "$50,000 per year," that is gross. Your net might be closer to $38,000 to $40,000, and that is what determines whether you can afford rent, a car payment, or a loan.

The calculation is straightforward: take your gross income, subtract mandatory withholdings (federal income tax, state income tax if your state has one, Social Security, and Medicare), then subtract voluntary deductions (health insurance, 401(k) contributions, flexible spending accounts). What remains is your net income.

Key Takeaways

  • Net income is gross pay minus all taxes and deductions — it is the amount that actually hits your bank account.
  • Mandatory withholdings include federal and state income tax, Social Security (6.2 percent of gross), and Medicare (1.45 percent of gross).
  • Your W-4 form controls how much federal tax your employer withholds; claiming more allowances lowers withholding and raises your take-home pay.
  • Self-employed people calculate net income by subtracting business expenses from revenue, then paying self-employment tax (15.3 percent) on top of income tax.
  • Your pay stub shows both gross and net, along with each deduction, so you can see exactly where your money goes.

How mandatory withholdings reduce your gross pay

When you receive a paycheck, your employer is required by law to withhold certain amounts before you see the money. These are not optional — they come out regardless of what you want.

Federal income tax withholding is based on the W-4 form you fill out when you start a job. The more allowances you claim on that form, the less federal tax is withheld from each paycheck. If you claim zero allowances, more comes out. If you claim more allowances, less comes out. The IRS publishes withholding tables that your employer uses to calculate the exact amount based on your pay frequency and filing status.

Social Security tax is a flat 6.2 percent of your gross pay, up to a wage cap that changes each year. In 2024, you stop paying Social Security tax once you earn $168,600 in a calendar year. Medicare tax is 1.45 percent of all your gross pay with no cap. Together, these are called FICA taxes. If you are self-employed, you pay both the employee and employer portions (15.3 percent total).

State income tax varies by state. Nine states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire). Other states withhold between 1 and 13 percent depending on your income level and filing status. Your employer uses your state W-4 to determine how much to withhold.

Voluntary deductions that lower your take-home pay

Beyond taxes, you may have chosen deductions that come out before you see your paycheck. These reduce your net income but often provide a benefit — lower taxable income, health coverage, or retirement savings.

Health insurance premiums for employer plans are usually deducted pre-tax, meaning they lower both your net pay and your taxable income. If your employer offers dental, vision, or life insurance, those premiums come out the same way. 401(k) or 403(b) contributions (retirement plans) are also pre-tax, so contributing $500 per paycheck lowers both your take-home and your federal income tax bill.

Flexible Spending Accounts (FSAs) for healthcare or dependent care are pre-tax deductions. You set aside money before taxes, use it for may be able to access expenses, and save on taxes. Garnishments — court-ordered deductions for child support, student loan defaults, or wage garnishment from a judgment — are also subtracted from gross before you receive your net pay.

Some deductions are post-tax, meaning they come out after federal income tax is calculated. Union dues, charitable contributions, and some insurance products work this way. They lower your net pay but do not lower your taxable income for federal purposes.

How to read your pay stub and find your net income

Your pay stub (also called an earnings statement) is the document your employer gives you with each paycheck. It shows your gross pay at the top, then lists every deduction line by line, and ends with your net pay — the amount you actually receive.

The stub typically shows: gross pay (your salary or hourly wage times hours worked), then each deduction with its amount and year-to-date total. Federal income tax withholding, Social Security, Medicare, state tax, and any voluntary deductions appear separately. At the bottom is your net pay and the method of payment (direct deposit, check, or card).

If your net pay seems wrong, check three things: your gross pay (did you work the hours listed?), your withholding (did you change your W-4 recently?), and new deductions (did you enroll in health insurance or a 401(k)?). Your employer's payroll department can explain any line item you do not recognize.

Calculating net income if you are self-employed

Self-employed people do not have an employer withholding taxes, so the calculation is different. You start with your total revenue (money you earned), subtract all business expenses (supplies, equipment, rent, utilities, vehicle costs, professional services), and the result is your net business income.

From that net business income, you then owe self-employment tax (15.3 percent for Social Security and Medicare combined) and federal income tax. You do not have an employer to withhold these, so you either pay quarterly estimated taxes or pay a large amount when you file your tax return. Many self-employed people set aside 25 to 30 percent of their net business income to cover taxes.

Self-employed net income is also what you report to lenders when you explore for a mortgage, car loan, or business loan. They want to see your tax returns for the past two years to verify the income you claim.

The difference between net income and take-home pay

Net income and take-home pay are often used interchangeably, but they can mean slightly different things depending on context. Net income usually refers to the amount on your pay stub after all deductions. Take-home pay sometimes includes additional factors like whether you have a second job, side income, or irregular expenses.

For budgeting purposes, use your net income from your pay stub as your baseline. That is the money you can count on each month. If you have a side business or freelance work, calculate the net income from that separately and add it only if it is consistent.

Some people also distinguish between net income and spendable income — the money left after you pay fixed obligations like rent, insurance, and loan payments. That is a personal budgeting calculation, not a financial or tax term, but it is useful for understanding how much discretionary money you actually have.

Why your net income matters for loans and financial decisions

When you explore for a mortgage, car loan, personal loan, or credit card, lenders look at your net income (or sometimes gross income, depending on the lender) to decide whether you can afford the payment. They want to see that your monthly debt payments do not exceed 43 percent of your gross monthly income, though some lenders use net income for this calculation.

Landlords also ask about income when you explore for an apartment. Many require that your monthly rent not exceed 30 percent of your gross monthly income. If your gross is $4,000 per month, they want to see that rent is no more than $1,200.

For government programs — unemployment insurance, housing information, food information — your net income (or sometimes your gross income minus certain deductions) determines whether you meet the income limits. The specific definition varies by program and state.

Frequently Asked Questions

Why is my net income so much lower than my salary?

Federal income tax, Social Security, and Medicare together typically take 20 to 30 percent of your gross pay. If you also have health insurance premiums, 401(k) contributions, or state income tax, the gap widens. A $50,000 salary might net $37,000 to $40,000 depending on your deductions and tax situation.

Can I change how much federal tax is withheld from my paycheck?

Yes, by submitting a new W-4 form to your employer's payroll department. Claiming more allowances lowers withholding and raises your net pay each month, but you may owe taxes when you file your return. Claiming fewer allowances raises withholding and may result in a refund.

Is net income the same as taxable income?

No. Net income is what you take home. Taxable income is what you owe federal income tax on, and it is calculated differently. Pre-tax deductions like 401(k) contributions and health insurance premiums lower your taxable income but are already subtracted from your gross to calculate net income.

How do I calculate my monthly net income if I am paid weekly?

Multiply your weekly net pay by 52 weeks, then divide by 12 months. If your pay varies (hourly work, commission, tips), use an average of the past three months. For budgeting, use a conservative estimate rather than your best month.

What happens to my net income if I get a raise?

Your net income increases, but not by the full amount of the raise. If you get a $5,000 annual raise, your net increase is typically $3,500 to $4,000 after taxes and deductions. The exact amount depends on your tax bracket and what deductions you have.
