How does this estimate federal withholding for 2026?

It annualizes your pay, subtracts the 2026 standard deduction ($15,750 single / $31,500 joint), applies the 2026 brackets, then divides the annual tax across your pay periods. A single filer earning $2,500 biweekly (26 periods) annualizes to $65,000, owes about $5,061 in federal income tax, or roughly $195 per paycheck.

What FICA taxes come out of my paycheck?

Social Security is 6.2% on wages up to the $176,100 wage base, and Medicare is 1.45% with no cap. On a $2,500 paycheck that is $155 Social Security and $36.25 Medicare, $191.25 of FICA before income tax.

Why does pay frequency change the result?

More frequent paychecks mean smaller per-check amounts but the same annual total. Weekly pay uses 52 periods, biweekly 26, semimonthly 24, and monthly 12, so the annual tax simply spreads across more or fewer checks; the yearly net pay is the same.

Will this match my actual W-4 withholding exactly?

Not exactly. Real W-4 withholding uses IRS percentage-method tables with allowances, extra withholding, and multiple-job adjustments. This tool gives a clean bracket-based estimate of the income tax plus FICA, which is close for a single job with the standard deduction.

Estimate your 2026 take-home pay

Want to know what actually lands in your bank account each payday? This calculator annualizes your gross pay, applies the 2026 federal brackets and standard deduction, adds FICA, and shows the income tax, Social Security, Medicare, and net take-home for each pay period.

How it works

The tool annualizes your per-period gross pay, removes the standard deduction, taxes the rest with the 2026 brackets, then divides by your number of pay periods.

annual wage    = gross per period * periods
annual taxable = max(0, annual wage - standard deduction)
annual tax     = progressive 2026 brackets on taxable
income tax /period = annual tax / periods
FICA /period   = gross * 0.062 (SS, capped at 176,100/yr) + gross * 0.0145
take-home      = gross - income tax/period - FICA/period

Pay frequencies are weekly (52), biweekly (26), semimonthly (24), and monthly (12). The standard deduction is $15,750 single and $31,500 joint for 2026.

Example

A single filer earns $2,500 biweekly across 26 pay periods, so $65,000 annually. After the $15,750 standard deduction, taxable income is $49,250, giving about $5,061 of federal income tax, or $195 per paycheck. FICA is $155 Social Security plus $36.25 Medicare, totaling $191.25. Take-home per check is about $2,113, and annual net pay is roughly $54,939.

Notes

This is an estimate, not tax advice. It does not model state or local income tax, pre-tax 401(k) or health deductions, W-4 allowances, or the percentage-method tables your employer actually uses. Brackets, the standard deduction, and the $176,100 Social Security wage base follow IRS figures for 2026; confirm with the IRS.
