Schedule comparison

Semi-monthly pay divides annual gross into 24 equal checks (twice per calendar month). Biweekly pay uses 26 checks per year, so each paycheck is slightly smaller but two months include a third check.

Net annual (semi-monthly schedule)$56,966.50

Tax estimates use 2026 federal brackets, FICA rates, and the federal standard deduction. State tax applies your entered rate to federally taxable income. Actual withholding may differ.

Semi-monthly vs biweekly take-home pay

Semi-monthly payroll pays twice per calendar month (24 checks per year). Biweekly payroll pays every two weeks (26 checks per year). The same annual salary produces different per-check amounts because the year is split into a different number of pay periods. This calculator estimates net pay for both schedules using 2026 federal brackets, FICA, and your state tax rate on federally taxable income.

To compare gross pay across frequencies without tax, use the biweekly pay calculator. For full annual take-home estimates with federal and state detail, use the salary calculator.

How semi-monthly net pay is calculated

Gross per check=Annual gross24\text{Gross per check} = \frac{\text{Annual gross}}{24}
Federal taxable=Gross−Pre-tax−Standard deduction\text{Federal taxable} = \text{Gross} - \text{Pre-tax} - \text{Standard deduction}

Federal income tax uses progressive 2026 brackets. FICA applies Social Security (6.2% up to the wage base) and Medicare (1.45%) on gross wages. State tax applies your entered percentage to federally taxable income.

Worked example

A single filer earning $72,000 per year with a 4.5% state tax rate and no per-check deductions has gross semi-monthly pay of $3,000. After federal tax, FICA, and state tax, estimated semi-monthly net pay is about $2,373.60. The same annual salary on a biweekly schedule nets about $2,191.02 per check because each check is a smaller slice of the year.

Frequently asked questions

Why is semi-monthly net pay higher per check than biweekly?
Annual salary divided by 24 yields larger checks than divided by 26. Biweekly employees receive two extra paychecks per year, which evens out annual take-home but lowers each individual check.
Can I enter hourly wages instead of salary?
Yes. Switch to hourly mode and enter your rate and weekly hours. The tool annualizes hourly pay as rate times hours times 52 weeks.
What tax year do these estimates use?
Federal brackets, FICA rates, and the standard deduction reflect tax year 2026. State tax uses your entered flat rate on federally taxable income.
Do pre-tax deductions reduce state tax?
Yes. Pre-tax 401(k) and similar deductions lower federally taxable income, which also lowers the state tax base in this calculator.
Will my actual paycheck match this estimate?
Actual withholding depends on your W-4, employer rounding, local taxes, and benefits. Use this as a planning estimate, not an exact payroll figure.
