Calculate employee payroll and deductions
This payroll calculator estimates an employee's take-home pay from gross wages by applying federal tax withholding concepts, FICA taxes, and optional state and pre-tax deductions. It's an educational estimator, not tax advice — actual withholding follows IRS Publication 15-T and your W-4.
Payroll arithmetic touches every worker yet hides behind acronyms. This guide walks through each deduction in the order they're actually computed, so the numbers in the tool make sense.
FICA is computed on gross pay before most deductions. The employee share of Social Security is 6.2% of wages up to the annual wage base (168,600 dollars for 2024 and 176,100 for 2025, per the Social Security Administration), and Medicare is 1.45% with no cap — combined, 7.65% on wages below the base.
Employers pay a matching 7.65%, so total FICA cost is 15.3% of wages. High earners additionally pay a 0.9% Additional Medicare Tax on wages above 200,000 dollars (250,000 for married filing jointly), withheld once year-to-date wages pass the threshold.
The computed values below show employee FICA at three wage levels — 62 dollars of Social Security plus 14.50 dollars of Medicare per 1,000 dollars of gross. These are exact multiplications of the statutory rates.
Pre-tax deductions (traditional 401(k), health premiums, HSA) reduce taxable income for income tax but not for Social Security and Medicare in most cases — FICA generally applies before those reductions.
| Gross wages ($) | Social Security 6.2% | Medicare 1.45% | Total employee FICA 7.65% |
|---|---|---|---|
| 1,000 | 62.00 | 14.50 | 76.50 |
| 2,000 | 124.00 | 29.00 | 153.00 |
| 4,000 | 248.00 | 58.00 | 306.00 |
Since 2020, withholding follows the Form W-4 system: percentage method or wage bracket tables from IRS Publication 15-T, adjusted for filing status, other income, dependents, and any extra withholding you request. The estimator approximates this with an effective rate approach; your employer's software computes the official figure.
Key point: withholding is not the tax itself. It's a pay-as-you-earn estimate reconciled on your annual return — over-withholding produces a refund (an interest-free loan to the Treasury), under-withholding produces a bill and possibly penalties if too large. The IRS withholding estimator helps tune your W-4.
The canonical order: start with gross pay; subtract pre-tax deductions to get taxable wages; compute FICA on gross (or per-plan rules); compute income tax on taxable wages; subtract post-tax deductions (Roth 401(k), garnishments, union dues); the remainder is net pay.
Pay frequency matters for budgeting: multiply an hourly rate by 2,080 hours for annualized pay (40 hours × 52 weeks), then divide by 26 for biweekly or 24 for semimonthly checks. A 25-dollar hourly wage is 52,000 dollars a year before any deductions.
['Pay frequency changes check size but not annual pay: the same 52,000-dollar salary is 2,000 dollars weekly (÷26), 1,000 dollars weekly is not the same as 1,000 dollars semimonthly — multiply any single check by its periods per year (52, 26, 24, or 12) to annualize before comparing.', 'Overtime under the FLSA is 1.5× the regular rate past 40 hours in a workweek, and the regular rate must include most bonuses and shift differentials — a common compliance error is computing overtime on base rate alone. Some states add daily-overtime rules; California, for example, requires overtime after 8 hours in a day.', 'Employers must keep payroll records (hours, rates, deductions) for at least three years under FLSA rules, and issue W-2s to employees by January 31 each year. Workers should reconcile final pay stubs against the W-2 annually — mismatched YTD figures are how errors surface.']
['State income tax varies from zero (states like Texas, Florida, and Washington levy no personal income tax on wages) to top marginal rates above 10% in California and Hawaii. Most states use a progressive structure resembling the federal brackets; a handful use flat rates. Local payroll taxes — city taxes in Ohio, or local taxes in Pennsylvania and Maryland — add small percentages in some municipalities.', 'Worked net-pay sketch for a single filer earning 2,000 dollars biweekly in a no-income-tax state: FICA takes 153 dollars (7.65%), and 2025 federal brackets for a 52,000-dollar annual income put most withholding in the 12% bracket after the standard deduction — leaving a rough take-home near 1,620 dollars per check. Your real figure depends on W-4 entries, benefits, and state.', 'Self-employed workers face the mirror image: they pay both halves of FICA as self-employment tax — 15.3% on 92.35% of net earnings up to the Social Security base — but deduct half of it from taxable income. Quarterly estimated payments replace employer withholding.']
What is the FICA tax rate?
The employee share is 6.2% for Social Security (on wages up to the annual wage base — 176,100 dollars in 2025) plus 1.45% for Medicare (no wage cap), totaling 7.65%. Employers pay a matching 7.65%.
How do I calculate net pay from gross pay?
Subtract pre-tax deductions, then FICA (7.65% employee share) and estimated income tax withholding, then post-tax deductions like Roth 401(k) contributions. What remains is net (take-home) pay. This calculator approximates each step.
How much of my paycheck goes to Social Security?
6.2% of gross wages, up to the annual wage base of 176,100 dollars in 2025 — about 62 dollars per 1,000 dollars earned. Above the base, Social Security withholding stops for the year; Medicare's 1.45% continues.
What's the difference between pre-tax and post-tax deductions?
Pre-tax deductions (traditional 401(k), health premiums, HSA/FSA) reduce taxable income for income tax withholding. Post-tax deductions (Roth 401(k), wage garnishments) come out after taxes are computed and don't lower your taxable wages.
Is a bigger tax refund good?
A large refund means you over-withheld all year — an interest-free loan to the government. Adjusting your W-4 to bring withholding closer to actual liability puts that money in each paycheck instead. Aim for a small refund or small balance due.
