What this payroll calculator does
Estimate gross payroll and common FICA deductions from employee earnings.
How to use the calculator
Use this calculator for planning and rough payroll estimates. Actual payroll can involve federal income-tax withholding, state/local taxes, benefits, retirement plans, wage garnishments and employer-specific rules.
How the calculation works
The calculator estimates gross wages and selected payroll deductions based on the inputs and tax assumptions in the current build. It is not a substitute for payroll software or tax filing calculations.
What the result means
The number shown is best used as a planning estimate. Change one assumption at a time to see which inputs have the largest effect. For financial decisions, compare the result with current statements, lender disclosures, employer information or other authoritative records.
Important assumptions and limitations
FICA treatment and federal withholding are governed by tax rules that can change. For 2026 federal parameters, use current IRS guidance and your payroll provider’s current tables.
