What this paycheck model includes
The script subtracts retirement from gross pay before applying the entered federal, state, and local rates. It then adds a simplified 7.65% FICA line and subtracts benefits and other deductions.
Per-paycheck inputs
Gross pay, benefits, and other deductions are entered for one pay period. Pay frequency only changes the annualized projection.
Know the limits
The model does not implement live tax tables, Social Security wage caps, Additional Medicare Tax, state-specific rules, W-4 details, or employer payroll adjustments.
Frequently Asked Questions
What does this paycheck calculator estimate?
It estimates net pay for one paycheck and annualized net pay from gross pay, pay frequency, user-entered withholding rates, FICA, retirement, benefits, and other deductions.
Which deductions are included?
The model includes federal, state, and local withholding rates, a simplified FICA line, a retirement percentage, benefits, and other flat deductions entered for the paycheck.
Are the tax rates current for every state?
No. Federal, state, and local rates are inputs rather than a live tax table, so verify your paystub, tax year, location, and filing details before relying on the result.
How is annualized pay calculated?
The calculator multiplies the estimated net paycheck by the selected frequency: 52 weekly, 26 biweekly, 24 semimonthly, or 12 monthly payments.
Is this an official payroll calculation?
No. It is a browser-based planning estimate, not payroll software, tax advice, or a filing calculation.
