Gross to Net Salary Calculator - Take-Home Pay

Gross salary is compensation before taxes and payroll deductions. Net salary, or take-home pay, is the amount left after income tax, Social Security, Medicare, benefit premiums, retirement contributions, and other elected deductions. Two employees with the same salary can receive different checks because filing status, state rules, health plans, retirement elections, and pay frequency differ. The take-home pay estimate organizes those moving parts into a transparent planning figure. Federal income tax is modeled progressively: each slice of taxable income is charged at its bracket rate rather than applying the top marginal rate to the entire salary. The calculation subtracts an estimated standard deduction and pretax health and 401(k) contributions before applying the bracket schedule. The legacy allowance fields provide an additional planning adjustment, but modern federal Forms W-4 no longer use the old personal-allowance system. Treat allowances as scenario inputs, not filing instructions. Payroll taxes are separate from federal income tax. Social Security is estimated at 6.2% up to the modeled wage base, while Medicare is 1.45% with an additional amount above the applicable high-income threshold. State estimates are deliberately simplified: the selected California and New York options use representative effective rates, Illinois uses a flat-rate estimate, and the no-state-tax option applies zero. Local income tax, unemployment deductions, paid-leave programs, tax credits, bonuses, stock compensation, and employer benefit treatment are not included. Pay frequency changes only how the annual net amount is divided. Monthly uses 12 checks, biweekly uses 26, weekly uses 52, and annual uses one. It does not change annual tax in this model. Monthly benefit inputs are multiplied by 12. Some payroll systems use 24 semimonthly checks or occasionally produce a third biweekly paycheck in a month, so compare annual totals when reconciling a paystub. Use the result for budgeting, offer comparisons, or evaluating contribution changes. Do not use it as a tax return or exact payroll forecast. Tax law, wage bases, deductions, and withholding tables change over time, and actual withholding is a prepayment rather than final tax. Review a current paystub, official tax guidance, and payroll documentation before making a decision based on the estimate.
