What does that salary actually look like in your bank account?

Your gross annual salary is divided by the number of pay periods per year — 52 for weekly, 26 for biweekly, 24 for semi-monthly, 12 for monthly — to get your gross pay per period. Pre-tax deductions come off first: your 401k or 403b contribution, health insurance premium, HSA contribution, and any other pre-tax benefits you specify reduce your gross pay before federal income tax is calculated. This matters because those deductions lower your taxable income, not just your take-home — contributing to a 401k reduces what you owe in federal taxes in the same pay period, making the real after-tax cost of contributing less than the gross dollar amount you're setting aside.

Federal income tax is then estimated using the current marginal bracket structure, applying each bracket rate only to the income falling within that bracket — not your entire income at the highest rate you reach. FICA taxes — Social Security at 6.2% and Medicare at 1.45% — apply to your gross pay (not your post-deduction taxable income), up to the Social Security wage base for the year. State income tax is estimated using a simplified flat percentage based on your state selection, since modeling every state's exact bracket structure and deductions would require a full state-by-state tax engine.

The result is an estimate of your take-home pay per period, not a payroll guarantee. Actual withholding is determined by your W-4 elections, additional withholding you may have specified, any garnishments, and details your employer's payroll system uses that this calculator doesn't see. For exact figures, your employer's pay stub or payroll portal is the authoritative source. This calculator is built to answer a different question: given a salary you're considering, what does the math say your take-home will roughly be?

Salary negotiations happen in gross annual numbers, but you live on the net. Most people don't have a clear sense of their actual take-home until the first paycheck from a new job arrives, which is a strange way to make one of the most significant financial decisions of the year. A $10,000 gross raise does not add $10,000 to your annual take-home. Depending on your existing income, the marginal federal rate on that $10,000 might be 22% or 24%, with state tax on top — meaning the real after-tax value of a $10,000 raise is commonly $6,000-$7,000, not $10,000.

This also matters when comparing job offers. A $95,000 salary with a strong 401k match in a no-income-tax state often has higher take-home than a $100,000 salary with a weak match in a 5% income tax state. The gross salary comparison points one direction; the net comparison may point the other. This calculator lets you run that comparison before signing an offer letter rather than after the first paycheck.

Pre-tax deductions create another counterintuitive effect: contributing more to your 401k doesn't reduce your take-home by the full contribution amount. If your marginal tax rate is 22% and you increase your 401k contribution by $100 per paycheck, your take-home drops by roughly $78 — the remaining $22 that would have gone to federal tax is now in your retirement account instead. The actual cost of saving more is lower than the stated deduction amount.

Pre-tax benefits reduce your taxable income before any income tax is calculated. A health insurance premium of $300 per month paid pre-tax doesn't just save you $300 — it saves you $300 plus the income tax you would have paid on that $300. At a 22% marginal rate, a $300/month pre-tax premium costs you about $234 in actual take-home reduction, not $300. The same logic applies to 401k contributions, HSA contributions, FSA contributions, and any other employer benefit offered on a pre-tax basis.

HSAs deserve particular mention: contributions reduce your taxable income now, the money grows tax-free, and qualified withdrawals for medical expenses are also tax-free. That triple tax advantage makes the HSA, if you're eligible for one, one of the most effective savings vehicles available — and its effect on your paycheck is the same as any other pre-tax deduction: you see a smaller gross number but more of your money goes to you rather than to taxes.

This calculator uses simplified tax estimates. It does not model every filing status edge case, alternative minimum tax, the additional 0.9% Medicare surtax that applies above higher income thresholds, multi-state taxation for remote workers, or the many other details of a full tax calculation. Federal and FICA tax rates also change — verify current rates at irs.gov before making decisions that rely on precision.

Your W-4 withholding elections have significant effects on actual withholding that this calculator doesn't model — if you claimed additional withholding allowances or have specific instructions on your W-4, your paycheck will differ from what any estimate produces. For precision, your employer's payroll portal, an official pay stub, or a tax professional are the authoritative sources. This calculator is built for planning and comparison, not for tax filing.
