Paycheck Calculator
- Browser-based

Enter gross pay for one paycheck, optional federal and state tax percentages, and other flat deductions to estimate total deductions and take-home pay. This is a clearly labeled simplified estimate, not a full payroll tax engine.
100% Client-Side
Your data never leaves your computer.
How to use this tool
Enter your gross pay for one paycheck period. Add estimated federal tax, state tax, and other deduction percentages or flat amounts, then calculate to see total deductions and estimated take-home pay.
Worked example
Example: $3,200 gross biweekly pay with 15% federal tax, 5% state tax, and $150 in other deductions leaves about $2,370 take-home per paycheck.
How it works
Enter gross pay for one paycheck and optional deduction percentages or flat amounts for federal tax, state tax, and other deductions. Total deductions are subtracted from gross pay to estimate take-home pay. This is a simplified estimate—not a full payroll engine with brackets, FICA, or benefits.
Limitations
This is a simplified educational estimate only. It does not model filing status, tax brackets, FICA, credits, or employer-specific rules. Confirm amounts with your payroll provider or a tax professional.
