How the Paycheck Calculator Works
This calculator estimates your US take-home pay by subtracting federal income tax (using 2025 brackets and standard deduction), state income tax (flat rate approximation), FICA taxes (Social Security + Medicare), and your 401k contribution from gross salary.
On a $75,000 salary with single filing, 5% state tax, and 6% 401k contribution, your estimated take-home is roughly $52,000 per year or about $4,300 per month.

Frequently Asked Questions
How accurate is this calculator?
It provides a reasonable estimate using 2025 federal tax brackets and standard deduction. Actual withholding depends on your W-4, state-specific rules, local taxes, and deductions.
What is FICA?
FICA covers Social Security (6.2% on income up to $168,600) and Medicare (1.45% on all income). Your employer pays a matching amount.
Does 401k reduce my taxes?
Yes. Traditional 401k contributions are pre-tax, reducing your federal (and usually state) taxable income.
