Frequently Asked Questions
What is the Paycheck Calculator?
The Paycheck Calculator is a free online tool that estimate us take-home pay with federal, state, fica, 401(k), hsa, and health insurance deductions across weekly, bi-weekly, semi-monthly, and monthly pay periods.. It runs entirely in your browser with no installation or sign-up needed.
How accurate is the estimate?
It is a close estimate based on your entered federal/state rates and fixed FICA (SS 6.2%, Medicare 1.45%). Actual withholding varies with W-4, local tax, and state rules.
Does it handle the Social Security cap?
Yes — SS tax applies only to wages up to the 2024 base of $168,600. Medicare has no cap, with an extra 0.9% surtax above $200,000.
How do 401(k), HSA, and health insurance affect pay?
401(k) reduces income tax only (still FICA-taxed). HSA and Section-125 health premiums reduce both income tax AND FICA wages, so they save more per dollar.

What is the difference between gross pay and net take-home pay?
Gross pay is the full amount your employer agrees to pay you before anything is removed — the number printed on a job offer or salary agreement. Net take-home pay is what actually reaches your bank account after federal and state income tax, Social Security and Medicare (FICA), and any deductions like a 401(k), HSA, or health insurance premium come out. The gap between the two is usually substantial: a $75,000 salary rarely deposits $75,000, because taxes alone can claim a fifth or more of it. That difference is exactly why an offer letter feels bigger than your real paycheck. This calculator shows both figures side by side, breaking down each tax and deduction line by line so you can see precisely where the money goes before it lands.
Why is my paycheck a different size depending on the pay frequency?
Your annual pay stays the same, but how it's sliced changes each paycheck's size. A weekly schedule splits the year into 52 paychecks, bi-weekly into 26, semi-monthly into 24, and monthly into just 12. The same salary therefore produces a larger individual check the fewer times you're paid — a monthly paycheck is roughly twice the size of a bi-weekly one. Bi-weekly and semi-monthly are easy to confuse: bi-weekly means every two weeks (26 checks, occasionally three in a month), while semi-monthly means twice a month on fixed dates like the 15th and last day (always 24 checks). Picking the right frequency matters for budgeting rent and bills around actual deposit dates. Switch the pay frequency in this calculator to see how each option resizes your take-home per check.
What federal and state tax rate should I enter into the calculator?
This tool asks you to enter your own federal and state income tax rates as flat percentages, rather than guessing them, because real withholding depends on your W-4 entries, filing status, dependents, and local rules that no single rate can capture. For a realistic estimate, use your effective rate — total income tax divided by gross income from last year's return — rather than your top marginal bracket, since not all income is taxed at the highest rate. If you only know your bracket, your true effective rate is usually several points lower. For state tax, enter your state's flat rate, or zero if you live somewhere with no state income tax. Plug in your best figures here and adjust them until the breakdown matches a recent pay stub.
Why is my effective tax rate lower than my tax bracket?
Your tax bracket is the rate applied to your highest dollar of income, but your effective rate is the average across all your earnings — and the average is always lower. The calculator reports an effective rate by totaling federal tax, state tax, Social Security, and Medicare, then dividing by your gross pay. Pre-tax deductions pull that rate down further: 401(k) contributions shrink your taxable income, while HSA and Section 125 health premiums reduce both taxable income and FICA wages, so each pre-tax dollar lowers your overall burden. Social Security also stops at the wage base, so very high earners see Social Security's share of their effective rate shrink. That's why the single percentage here often surprises people. Adjust your deductions in the tool and watch the effective rate respond in real time.
How does the calculator handle Roth 401(k) and other post-tax deductions?
The calculator keeps pre-tax and post-tax money in separate fields because they affect your paycheck very differently. Traditional 401(k), HSA, and pre-tax health premiums come out before income tax is figured, lowering your taxable income. A Roth 401(k) is the opposite — contributions are made with money that has already been taxed, so they belong in the post-tax deduction field, entered as a dollar amount per pay period. The same field handles other after-tax items like wage garnishments, union dues, or charitable payroll giving. Because post-tax deductions don't reduce your taxes, every dollar you put there lowers take-home pay by a full dollar, unlike pre-tax contributions that are partly offset by tax savings. Enter your Roth or other after-tax amounts in that field to see their true effect on each paycheck.

About the Paycheck Calculator
The Paycheck Calculator estimates your US take-home pay — the amount that actually lands in your bank account after taxes and deductions come out of your gross wages. Enter what you earn, set your tax rates and deductions, and it breaks the paycheck down line by line for both a single pay period and the full year. It's built for anyone weighing a job offer, planning a budget, deciding how much to put into a 401(k), or simply trying to understand why the number on the offer letter is so different from the number that hits the bank.
Everything runs locally in your browser. Your salary, contributions, and tax inputs are never uploaded to a server, so your financial details stay on your own device. There's no sign-up, no paywall, and nothing to install — and you can copy the full breakdown or download it as a CSV when you're done.
How the calculator works
You start by entering gross pay on whichever basis you know it: an annual salary, or a monthly, bi-weekly, weekly, or hourly figure (for hourly, you also enter hours per week). The calculator converts that to an annual gross, then divides it across your chosen pay frequency:
- Weekly — 52 paychecks a year
- Bi-weekly — 26 paychecks (every two weeks)
- Semi-monthly — 24 paychecks (twice a month, e.g. the 15th and the last day)
- Monthly — 12 paychecks
From there it subtracts pre-tax deductions, applies income tax and FICA, removes any post-tax deductions, and shows your net take-home per period and per year, along with your effective tax rate.
Taxes and FICA, explained
Federal and state income tax are applied as flat percentages you enter yourself, because real withholding depends on your W-4, filing status, and local rules that no single rate can capture. Use your marginal or effective rate to get a realistic estimate.
FICA is fixed by law and the calculator applies the statutory rates automatically:
- Social Security — 6.2% of wages, but only up to the Social Security wage base ($168,600 for 2024). Earnings above that cap aren't subject to Social Security tax.
- Medicare — 1.45% of all wages with no cap, plus an Additional Medicare surtax of 0.9% on wages above $200,000.
This is an estimate, not a substitute for your actual pay stub. Withholding varies with your W-4 entries, state and local taxes, and exemptions.
Pre-tax deductions and why they matter
Where you put pre-tax dollars changes how much tax you save, and the calculator models the difference precisely:
- 401(k) contributions (entered as a percent of pay) lower your taxable income for federal and state tax, but they're still counted as FICA wages — so they cut income tax only.
- HSA contributions and health insurance premiums (entered per pay period) are treated as Section 125 pre-tax items that reduce both your income tax and your FICA wages, so each dollar saves a bit more than a 401(k) dollar.
A separate post-tax deduction field handles things taken out after taxes, such as Roth 401(k), garnishments, or union dues.
Putting it to use
Common ways people use the Paycheck Calculator:
- Compare job offers with different salaries, states, and benefits to see real take-home, not just headline pay.
- Tune your 401(k) or HSA by raising the contribution and watching how take-home pay barely moves once tax savings are factored in.
- Budget by pay period so your rent, bills, and savings are sized to the money you actually receive.
- Sanity-check a pay stub by matching the line-item breakdown against your employer's numbers.
Enter your gross pay above, adjust the deductions to match your situation, and read off your net pay for each paycheck and for the year.
