How does this calculator work?
Semi-monthly gross = Annual salary ÷ 24. Enter your salary, combined tax rate, and per-period deductions to see your twice-a-month take-home pay alongside daily, weekly, monthly, and hourly equivalents. Tax figures are editable estimates — check your pay stub for exact amounts.
Formula
How this is calculated
Semi-monthly pay divides the year into 24 equal periods — typically on the 1st and 15th, or the 15th and last day, of each month. Because every month (even February) has exactly two pay dates, the gross amount per paycheck is always Annual Salary ÷ 24, which differs from bi-weekly pay (Annual ÷ 26, where two months in the year have three paychecks).
To estimate take-home pay, this calculator subtracts estimated income tax (at the rate you enter — this should reflect your combined marginal federal and state rate, which varies by jurisdiction) and any flat per-period deductions such as health insurance premiums or retirement contributions. Tax figures are editable estimates only; exact withholding depends on your filing status, allowances, and employer-specific withholding tables. For an authoritative net-pay figure, check your pay stub or use your employer's payroll calculator.
The calculator also converts the annual salary into hourly rate (assuming 52 weeks at your entered weekly hours), daily rate (÷ 260 working days), weekly, and monthly equivalents so you can compare compensation across different time frames.
Frequently asked questions
Semi-monthly means exactly twice per month — 24 paychecks per year. Bi-weekly means every two weeks — 26 paychecks per year (since 52 weeks ÷ 2 = 26). The annual total is the same but bi-weekly paychecks are slightly smaller, and two months per year will have three paychecks.
This calculator uses a flat tax rate for simplicity. Real withholding uses graduated brackets, filing status (single/married/head of household), withholding allowances, and employer tables. Pre-tax deductions (401k, FSA, HSA) also reduce the taxable amount before withholding is applied.
Multiply the semi-monthly gross by 24. For example, a $2,500 semi-monthly paycheck equals a $60,000 annual salary ($2,500 × 24).
