About Paycheck Atlas

Our purpose

Paycheck Atlas is an independent calculator website created to help workers translate gross compensation into a clearer planning estimate of take-home pay. It is not a payroll processor, tax-preparation service, employer, government agency, or financial adviser.

How the calculators work

The tools annualize the income entered by a visitor, apply published federal income-tax assumptions, estimate Social Security and Medicare, account for selected pre-tax deductions, and divide the result by the selected pay schedule. Location pages may include an editable state or local planning rate. That editable rate is intentionally visible and is not presented as an official withholding table.

Sources and review

Federal assumptions are reviewed against information published by the Internal Revenue Service and Social Security Administration. State-specific decisions should be checked against the relevant state or local revenue agency. We review the calculators when a new tax year begins or when a material rule changes, but payroll results can still differ because of W-4 selections, credits, benefits, local rules, year-to-date wages, and employer payroll methods.
