Gross-to-net pay
Gross-to-net pay, explained step by step
Your offer letter says one number. Your bank account shows another. Between those two figures sits a defined sequence of withholdings and deductions — once you see the order, you can estimate your own take-home pay with reasonable accuracy.
Two numbers, one pay period
Gross pay is what you earned. Net pay is what lands. The gap is not a single fee or a single tax — it is a stack of withholdings applied in order, each calculated on the amount left after the step before it. This page walks that order from top to bottom so you can follow your own stub line by line and build a budgeting plan from the number that actually arrives.
Gross pay: where the calculation starts
Gross pay is your total earnings before any withholding. For salaried employees it is the annual salary divided across pay periods. For hourly workers it is hours worked multiplied by the rate, plus overtime where it applies. Bonuses, commissions, and tips count as gross pay too.
This is the figure payroll software starts from, and it is usually the largest number on your stub. Two details are worth checking before you go further. First, confirm your pay period length — weekly, bi-weekly, semi-monthly, and monthly periods split the same annual salary into different per-check amounts. Second, confirm which earnings were included: a commission paid this period but earned last quarter will still show up in this period's gross.
Hours worked, overtime, and pay period length all feed the gross figure before a single withholding is applied.
Federal income tax withholding
Employers withhold federal income tax from each paycheck based on your W-4 elections and the IRS withholding tables. The amount depends on your filing status, dependents, and any extra withholding you requested. It is an estimate of your annual tax bill, divided across your pay periods.
- What sets the amount
- Filing status, dependents claimed, and any additional withholding you asked for on your W-4.
- If too little comes out
- You cover the difference when you file, which can mean a balance due rather than a refund.
- If too much comes out
- You get the overage back at filing time. Adjusting your W-4 is the standard way to correct either direction.
Changing your W-4 does not change your tax rate. It changes how much of the estimate is collected from each check, which is a cash-flow decision as much as a tax one.
The rule that orders everything
Every withholding is calculated on what remains after the one before it.
That is why the order on your stub matters more than any single line. Move a deduction from after-tax to before-tax and the tax math below it changes.
FICA: Social Security and Medicare
Social Security and Medicare taxes, together called FICA, come out of nearly every paycheck at fixed rates. Your employer withholds your share and pays a matching share of its own, which is why FICA appears on your stub as employee taxes but costs your employer more than you see.
Unlike income tax withholding, FICA is not a guess. The rates are set, and there is an annual wage limit on the Social Security portion — once your year-to-date wages pass it, that piece stops coming out for the rest of the year while Medicare continues. If your net pay rises noticeably late in the year with no raise, that limit is usually the reason.
State and local taxes
Most states levy income tax on wages, and some cities and counties add their own. A handful of states have no income tax, which is why two workers with identical salaries in different states can take home noticeably different amounts.
If you live in one state and work in another, the rules can interact in ways worth confirming with a tax professional — residency, reciprocity agreements, and where the work is physically performed can each change the result. Your pay stub lists these withholdings separately, which makes it possible to see exactly what your state and locality took.
When to ask
- •You moved mid-year and only part of your income is taxed in each state.
- •You work remotely for an employer based in another state.
- •Your city or county added a local wage tax you did not expect.
Deductions: what you elected and what you owe
Deductions fall into two broad groups. Voluntary deductions are benefits you chose: health insurance premiums, dental, retirement contributions, life insurance. Involuntary deductions are obligations such as wage garnishments or court-ordered withholdings.
Pre-tax deductions
These come out of your pay before income tax and often before FICA are calculated. Because they lower your taxable wages, they lower the tax withheld from each check. Traditional retirement contributions and many employer health plans sit here. The trade-off is that the money is not in your take-home pay now — it is either deferred to retirement or spent on a benefit.
Post-tax deductions
These come out after tax is calculated, so they do not reduce the tax on the check. Roth-style retirement contributions and some insurance products work this way. Involuntary withholdings such as garnishments also sit here. The distinction changes your tax bill, so it is worth knowing which category each of your deductions belongs to.
A quick way to tell them apart: if the deduction is labeled on your stub above the tax lines, it is almost certainly pre-tax. If it sits below them, treat it as post-tax until your benefits paperwork says otherwise.
Employer costs you never see on your stub
Your employer pays its own share of Social Security and Medicare, unemployment insurance at the state and federal level, and often a portion of your health premium. None of this appears in your net pay, but it is part of what you cost to employ.
Small employers budgeting for a new hire should account for these costs on top of gross salary, not instead of it. A salary figure that fits the budget on paper can strain it once employer taxes, insurance contributions, and any retirement match are added.
- Employer FICA match A matching share of Social Security and Medicare on top of what you contribute.
- Unemployment insurance State and federal programs your employer funds on covered wages.
- Health premium share Often a portion of the plan cost that never touches your stub.
- Retirement match Where offered, an employer contribution on top of your own deferral.
Exact employer costs vary by state, wage level, and plan design. Confirm the figures that apply to you rather than assuming a flat percentage.
From gross to net: a worked sequence
Take a salaried employee paid bi-weekly. Payroll starts with the gross amount for the period, applies pre-tax deductions, calculates federal withholding and FICA on the remaining taxable wages, applies state and local withholding, then subtracts post-tax deductions. The final figure is net pay, the amount deposited.
-
1
Gross for the period
Salary or hours plus overtime, split across this pay period.
-
2
Pre-tax deductions
Benefits chosen before tax come out and lower taxable wages.
-
3
Federal and FICA
Withholding and FICA are calculated on what remains taxable.
-
4
State and local
State, city, or county withholding is applied next where they apply.
-
5
Post-tax deductions
Everything remaining is subtracted, leaving the deposited net pay.
Every step has a defined order, and pay stubs typically list the results in roughly that sequence. If a stub looks confusing, read it top to bottom in this order before trying to reconcile it as a whole.
Why net pay matters for budgeting
Annual salary is useful for comparing offers. Net pay is what you budget with, because it is what actually arrives. Two jobs with the same gross salary can produce different take-home amounts if their benefits, state taxes, or withholding elections differ.
Build your budget from the net figure on your stub, then revise it whenever your withholding or deductions change — a benefits enrollment, a raise, a move, or a new dependent all shift the number that lands. If your pay cycle is not monthly, match the budget to the cycle rather than averaging everything into a monthly guess.
Questions people ask about take-home pay
Short answers to the three things that come up most often when someone compares a salary offer to a real deposit.
Why is my take-home pay lower than my salary divided by pay periods?
Because gross salary has not had taxes or deductions applied yet. Federal and state withholding, Social Security, Medicare, and any benefit deductions all come out before the money reaches your account. The result, net pay, is smaller than the gross figure by design.
Can I change how much tax is withheld?
Yes. You adjust your W-4 with your employer to change your filing status, dependents, or add extra withholding. That changes the estimate taken from each check, not the tax rate itself.
Do pre-tax deductions really lower my taxes?
Pre-tax deductions reduce your taxable wages before income tax and often FICA are calculated, so they lower the tax withheld from each check. Post-tax deductions do not. Check which type each of your benefits uses.
