How payroll calculator works
This calculator converts gross pay into an estimated net paycheck. Enter either an annual salary or an hourly rate plus hours per week, optionally add pre-tax deductions (like traditional 401(k) or health premiums), post-tax deductions (like Roth contributions or garnishments), pick a state, and choose a pay frequency. The calculator shows your net annual and per-paycheck take-home.
It applies the 2024 US federal income-tax brackets for a single filer (with the $14,600 standard deduction subtracted to get taxable income), then FICA: Social Security at 6.2% on wages up to the $168,600 wage cap, plus Medicare at 1.45% on all wages. State income tax uses a flat top-rate approximation drawn from public Department of Revenue data; sub-state brackets, credits, and local add-ons are not modeled, so treat it as an estimate.
The result shows each component (federal tax, Social Security, Medicare, state tax), the total tax, the effective tax rate, and the net per paycheck for your chosen frequency. It is a planning estimate, not tax advice; your actual withholding depends on your W-4, benefits, and local rules. Everything runs in your browser.
