Gross Pay vs Net Pay: How to Calculate Your Real Take-Home Paycheck
Gross pay vs net pay explained with full worked examples: federal tax, FICA, an optional state rate, and how a 401(k) or health insurance premium change what actually lands in your bank account.
A job offer almost always leads with one number, an annual salary or an hourly rate, and that number is gross pay, the first half of the gross pay vs net pay comparison this guide walks through. It is also, almost always, not the number that shows up in your bank account on payday. Between the offer letter and the deposit sits federal income tax, FICA, possibly a state tax, and whatever you have chosen to contribute to a 401(k) or pay toward health insurance before tax applies. Net pay is what survives all of that, and the gap between the two is rarely obvious until you calculate it by hand once.
This guide does that calculation by hand, more than once, with real numbers, so the mechanism is visible rather than assumed. It also covers the mistakes that most often make someone's own estimate come out wrong, and it works alongside this site's take-home-paycheck calculator, which automates every step below for tax years 2020 through 2026, three filing statuses, an optional state tax rate you supply, and 401(k), health insurance, and post-tax deductions.
What gross pay actually means
Gross pay is every dollar your employer pays you for a period, before any tax and before any deduction. For a salaried employee, annual gross pay is the number in the offer letter. For an hourly employee, gross pay for a period is the hourly rate multiplied by hours worked, plus any overtime premium, commission, or bonus earned in that period. Total annual income, monthly gross income, and gross wages are all the same underlying idea measured over a different span of time: the full amount earned, unreduced by anything that comes out afterward.
It is worth being precise here because "gross" gets used loosely in casual conversation. Gross salary is not "salary after some obvious deductions already removed." It is the full, contractual figure, and every tax and deduction this guide covers is subtracted from it, never added to it. If you are ever asked whether gross pay is before or after tax, the answer is always before, by definition. Net pay is the "after" side of that same sentence.
Everything that turns gross pay into net pay
A real paycheck can subtract several genuinely different things from gross pay, each with its own rule for what it applies to. Laying them out side by side is the fastest way to see why they do not all behave the same way.
| Deduction | What it is calculated on | Progressive or flat | Reduces FICA wages? |
|---|---|---|---|
| Federal income tax | Gross pay minus the standard deduction and any pre-tax deductions | Progressive brackets | No, calculated separately |
| Social Security (FICA) | Wages up to the annual wage base ($184,500 currently) | Flat 6.2% | N/A, this is FICA |
| Medicare (FICA) | All wages, no cap, plus an extra 0.9% above $200,000 single / $250,000 joint | Flat 1.45%, plus 0.9% above the threshold | N/A, this is FICA |
| State income tax (where it applies) | Varies by state; this guide's calculator uses a flat rate you supply | Depends on the state | No |
| Traditional 401(k) | A percent of gross pay, chosen by the employee | Not a tax; a deferral | No, FICA still applies to it |
| Pre-tax health insurance (Section 125) | A flat premium per paycheck | Not a tax; a deferral | Yes, it lowers FICA wages too |
| Post-tax deduction | A flat amount, e.g. a Roth contribution | Not a tax | No, applied after every tax above |
Two rows in that table are the ones people get backward most often. A traditional 401(k) contribution lowers the wages federal income tax and any state tax are calculated on, which is the entire point of it being "pre-tax," but it does not lower Social Security or Medicare wages: FICA taxes a dollar the moment it is earned, before a 401(k) deferral ever applies to it. A pre-tax health insurance premium, by contrast, is treated as a Section 125 cafeteria-plan deduction and does lower all three: federal, state, and FICA wages. Knowing which row you are in matters for figuring taxable income correctly, and it is the single most common source of a manually calculated paycheck coming out wrong.
Gross pay vs net pay in a full worked example: $75,000 in Texas, paid every two weeks
Start with a Single filer earning $75,000 in annual gross pay, paid biweekly (26 pay periods a year), living in Texas, which charges no state income tax, with no 401(k) or health insurance deduction yet.
Federal income tax. Figuring federal income tax is a bracket walk. The 2026 standard deduction for a Single filer is $16,100, so taxable income is $75,000 minus $16,100, or $58,900. Walking that through the 2026 brackets: the first $12,400 is taxed at 10%, for $1,240. The next $38,000, from $12,400 up to $50,400, is taxed at 12%, for $4,560. The remaining $8,500, from $50,400 up to the $58,900 taxable income, is taxed at 22%, for $1,870. Add those three amounts and federal income tax comes to $7,670.
FICA. Social Security is 6.2% of wages, and $75,000 is well under the current $184,500 wage base, so the full amount applies: $75,000 times 0.062 equals $4,650. Medicare is 1.45% with no cap: $75,000 times 0.0145 equals $1,087.50. Since $75,000 is below the $200,000 Additional Medicare Tax threshold, no additional Medicare tax applies here.
State tax. Texas charges none, so this line is $0. That is why a paycheck calculator Texas residents use can skip the state field, and why a Texas tax calculator or a paycheck estimator Texas employers hand out reduces to federal tax plus FICA. A salary calculator Texas page does the same.
Add federal income tax, Social Security, and Medicare together: $7,670 plus $4,650 plus $1,087.50 equals $13,407.50 in total tax for the year. Subtract that from $75,000 and annual net pay is $61,592.50. Divide by 26 pay periods and the deposited amount on each biweekly check is $2,368.94, noticeably below the $2,884.62 that $75,000 divided by 26 alone would suggest, because that simple division never accounted for any tax at all.
The same $75,000, three ways: what a state rate and a 401(k) really cost
Two people can earn an identical gross salary and still take home different amounts, because net pay depends on more than the number on the offer letter. Extending the example above shows exactly how much two common variables move the result, without changing gross pay by a single dollar.
| Scenario | Federal tax | State tax | FICA | Annual net pay | Net pay per biweekly check |
|---|---|---|---|---|---|
| Texas, no deductions | $7,670.00 | $0.00 | $5,737.50 | $61,592.50 | $2,368.94 |
| Same salary, a 4% flat state tax | $7,670.00 | $3,000.00 | $5,737.50 | $58,592.50 | $2,253.56 |
| Same salary, 4% state tax, plus a 6% 401(k) | $6,680.00 | $2,820.00 | $5,737.50 | $55,262.50 | $2,125.48 |
Notice the FICA column: it is identical, $5,737.50, in all three rows. Adding a state tax rate does not touch it, and adding a 401(k) contribution does not touch it either, exactly the rule the table earlier in this guide described. What does move is the federal and state tax, because the 401(k) row's taxable wages dropped from $75,000 to $70,500 (a 6% deferral of $4,500), which is also why federal tax fell from $7,670 to $6,680 and state tax fell from $3,000 to $2,820 in that third row. This is the mechanism behind a 401(k) match sometimes being described as a discount on saving: the money that goes into the account was never fully taxed in the first place.
What to enter in the state field
Texas is the easy case, and any tax calculator Texas workers open gives the same answer with the state field at zero. Most people live somewhere with a wage tax, though. A calculator that takes one flat state rate can still handle every state if you choose the rate carefully.
| Where you work | How it taxes wages | What to enter |
|---|---|---|
| Texas, Florida, Nevada, Washington, Tennessee, Wyoming, South Dakota, Alaska, New Hampshire | No tax on wages | 0% |
| Pennsylvania | Flat 3.07%, plus a local earned income tax | 3.07% plus your local rate |
| North Carolina | Flat rate set by law and lowered in steps | The current year's flat rate |
| Indiana | Flat state rate, plus a county tax | State rate plus your county rate |
| Ohio | State tax, plus a municipal tax in most cities | Your effective state rate plus the city rate |
| New Jersey, New York | Graduated brackets | Your effective rate from last year's return or a pay stub |
No wage tax does not always mean no state deduction. Washington, for one, takes premiums for its long-term care and paid family leave programs, and Alaska takes a small unemployment insurance amount from employees, so a Washington pay stub can still show state lines even at 0% income tax.
What is FIT on my paycheck, and the other pay stub lines
What is FIT on my paycheck? It is federal income tax, the line that changes with the brackets. The other abbreviations on a pay stub map onto the same list of deductions this guide covers.
| Pay stub line | Meaning | Taken from |
|---|---|---|
| FIT | Federal income tax | Wages after the standard deduction and pre-tax deductions |
| SS or OASDI | Social Security | Wages up to the annual wage base |
| MED | Medicare | All wages |
| SIT | State income tax | State taxable wages |
| SDI or TDI | State disability insurance | Wages, in states that have it |
| 401K | Traditional 401(k) deferral | Gross pay, before income tax |
Converting an hourly wage into an annual net figure
How to find annual income from an hourly rate is the first half of questions like "$25 an hour is how much a year after taxes", which really ask for two calculations chained together: turn the hourly rate into an annual gross figure, then run that gross figure through the same tax calculation a salary uses.
At $25 an hour, working a standard 40-hour week for 52 weeks, annual gross pay is $25 times 2,080 hours, or $52,000. For a Single filer in a state with no income tax, subtract the $16,100 standard deduction to get $35,900 in taxable income. The first $12,400 is taxed at 10% for $1,240, and the remaining $23,500 up to $35,900 is taxed at 12% for $2,820, for $4,060 in federal income tax. Social Security is $52,000 times 6.2%, or $3,224, and Medicare is $52,000 times 1.45%, or $754. Total tax is $8,038, leaving $43,962 in annual net pay, or roughly $21.14 an hour once that figure is spread back across the same 2,080 hours. The same $52,000 divided into 26 biweekly checks comes to $1,690.85 net per check.
The method does not change for a different hourly rate or a different number of hours; only the inputs to the first step do. Multiply hours by rate to reach gross pay, then apply the same federal, FICA, and any state calculation this guide has already walked through twice. It is also how to calculate federal income tax for any salary: subtract the standard deduction, then walk the brackets.
For a quick comparison, the table runs common hourly rates through the same 2026 Single-filer calculation, in a state with no income tax, at 2,080 hours a year. Reading down it answers the usual questions: $30 an hour is how much a year after taxes? About $52,318. And $40 an hour is how much a year after taxes? About $67,361. Questions without the tax part, like $29 an hour is how much a year, or $42 an hour is how much a year, are the gross column: $60,320 and $87,360.
| Hourly rate | Annual gross | Annual net income | Net per hour |
|---|---|---|---|
| $19 an hour | $39,520 | $33,934 | $16.31 |
| $22 an hour | $45,760 | $38,948 | $18.73 |
| $23 an hour | $47,840 | $40,619 | $19.53 |
| $25 an hour | $52,000 | $43,962 | $21.14 |
| $26 an hour | $54,080 | $45,633 | $21.94 |
| $29 an hour | $60,320 | $50,647 | $24.35 |
| $30 an hour | $62,400 | $52,318 | $25.15 |
| $38 an hour | $79,040 | $64,435 | $30.98 |
| $40 an hour | $83,200 | $67,361 | $32.39 |
| $42 an hour | $87,360 | $70,288 | $33.79 |
Why pay frequency changes the number on each check, not the total you keep
Jobs that pay weekly, such as restaurants, retail and construction, hand out 52 smaller checks, and being paid weekly, biweekly, semi-monthly, or monthly changes how many checks you see and how large each one is, but it does not change your annual net pay by itself, since the same total tax is simply spread across a different number of periods. A biweekly employee sees 26 checks a year; a semi-monthly employee, paid on fixed dates like the 15th and the last day of the month, sees 24; a weekly employee sees 52. The same $61,592.50 annual net pay from the Texas example above works out to $2,368.94 biweekly, $2,566.35 semi-monthly, or $1,184.47 weekly, three different-looking numbers describing the exact same annual outcome.
The one place pay frequency can genuinely matter, rather than just looking different, is a mid-year raise, bonus, or a change in withholding: because withholding calculations often assume a steady rate across the year, a single unusually large check (a bonus, for instance) can be withheld at a higher effective rate for that one check even though the annual totals still reconcile correctly. Day-to-day budgeting math is unaffected by frequency; a single large or small check within the year sometimes is.
Common mistakes when estimating take-home pay
Forgetting FICA entirely. It is easy to calculate federal income tax alone and mistake that for the full tax picture, but Social Security and Medicare are separate, mandatory, and typically add up to 7.65% of wages below the Social Security wage base, a large enough share to meaningfully change a net pay estimate on their own.
Assuming every state charges income tax. Several states, Texas, Florida, and Washington among them, charge none, and a salary calculator Florida workers use skips the state line entirely, so plugging in a generic state rate for someone who lives in one of those states overstates their real tax by the full amount of that invented rate.
Confusing a 401(k)'s effect on FICA with its effect on income tax. As the comparison table above shows directly, a 401(k) contribution lowers federal and state taxable wages but never lowers the wages FICA is calculated on. Assuming otherwise understates FICA in a manual calculation.
Mixing up marginal and effective tax rates. A Single filer's income reaching the 22% bracket does not mean 22% of their entire income is taxed; the bracket walk in every example above shows only the slice of income inside each bracket being taxed at that bracket's rate, with the effective rate, total tax divided by gross pay, always ending up lower than the top marginal rate reached.
Using last year's brackets, or next year's, without checking. The standard deduction and bracket thresholds shift most years to keep pace with inflation, and 2025 in particular saw a mid-year legislative increase to the standard deduction on top of the usual annual adjustment. A figure that is exactly right for one tax year can be measurably off for an adjacent one.
Calculate your own numbers
Every example above answers the gross pay vs net pay question using the same sequence: start from gross pay, subtract any pre-tax deduction that applies, run the result through the federal brackets and FICA, subtract any state tax and post-tax deduction, and divide by however many pay periods apply. The take-home-paycheck calculator runs that exact sequence for your own numbers, across six tax years, all three common filing statuses, your own state rate if you supply one, and any 401(k), health insurance, or post-tax deduction you want to add, with a gross-to-net breakdown chart so the pieces are visible at a glance rather than buried in a single final figure.
