Salary Paycheck Calculator

The Same Salary Pays Differently Depending on Frequency

An annual salary divides down to a per-paycheck amount, but that per-check figure — and the taxes taken from it — shift depending on whether you're paid weekly, biweekly, semimonthly, or monthly. This calculator takes a fixed annual salary, splits it into the chosen pay frequency, and applies FICA plus your estimated federal and state rates to produce a net figure per paycheck.

The Formula

Gross Pay per Period = Annual Salary ÷ Pay Periods per Year
Net Pay = Gross Pay − Taxes (FICA + Federal + State) − Deductions

Same Salary, Four Pay Frequencies

$70,000 annual salary, 12% federal / 5% state tax, $100 pre-tax deduction per period
Pay FrequencyGross per PeriodNet per Period
Weekly (52/yr)$1,346.15$931.33
Biweekly (26/yr)$2,692.31$1,945.65
Semimonthly (24/yr)$2,916.67$2,114.71
Monthly (12/yr)$5,833.33$4,312.42

The pre-tax deduction is applied per period, so it removes more from annual taxable income at higher-frequency schedules (52 periods x $100 = $5,200/yr) than at monthly (12 x $100 = $1,200/yr) — a detail worth noting when comparing net totals across frequencies.

Where This Matters

  • Negotiating pay frequency — some employers offer a choice; seeing the per-check net for each option helps with cash-flow planning.
  • Budgeting around a fixed salary — knowing the exact net amount landing each period, rather than an annual estimate divided crudely.
  • New-hire paperwork — sanity-checking a first paycheck against expectations before raising a payroll question.
