About US Calculators

US Calculators covers take-home pay, federal and FICA payroll tax, 401(k)/HSA/FSA pre-tax benefit treatment, freelancer and 1099 tax set-aside planning, equity compensation (RSUs, stock options), state-specific salary comparisons, and job-offer and cost-of-living decisions — built specifically around US tax and payroll rules rather than a generic international formula.

Built on current IRS figures

Federal tax brackets, standard deductions, and FICA (Social Security and Medicare) rates and wage bases are sourced from current IRS guidance and updated as new tax years are announced. Where a calculation depends on state-specific rules, that's called out explicitly rather than assumed.

Estimates, not tax advice

Every calculator in this category is for informational and educational purposes only and is not tax, legal, or financial advice. Payroll withholding, employer benefit plans, and individual tax situations vary — confirm specifics with a qualified tax professional, your employer's payroll or benefits team, or the IRS directly.
