ReckonBoxFrom salary to what lands in your account
Take-home pay is your gross salary minus pretax deductions, federal income tax, Social Security, Medicare, and state income tax. Most paycheck tools give you the net figure and stop. This one keeps the four tax lines apart, because that is where the surprises live.
A single filer earning $100,000 in 2026, with no pretax deductions and no state income tax, keeps $79,180. Paid every two weeks, that is $3,045.38 per check across 26 paychecks. The $20,820 that went to taxes splits into $13,170 of federal income tax, $6,200 of Social Security, and $1,450 of Medicare, a 20.8% total tax rate.
| $100,000 single, biweekly, 2026 | Per year | Per paycheck |
|---|---|---|
| Gross pay | $100,000 | $3,846.15 |
| Social Security | $6,200 | $238.46 |
| Medicare | $1,450 | $55.77 |
| Federal income tax | $13,170 | $506.54 |
| Net take-home | $79,180 | $3,045.38 |
Why Social Security stops but Medicare does not
Social Security tax applies only to wages up to the annual wage base, which is $184,500 for 2026, so it caps out while Medicare keeps going. This is the line that changes the math for higher earners.
Social Security is 6.2% of your wages, but only on the first $184,500, so the most anyone pays into it in 2026 is $11,439. Earn $250,000 and your Social Security tax is still $11,439, not 6.2% of the whole quarter million. Medicare is different: it is 1.45% on every dollar, and it adds another 0.9% on wages above $200,000 for a single filer or $250,000 for a joint one. So as income climbs, the Social Security share of your paycheck shrinks in percentage terms while Medicare inches up.
What a 401(k) does and does not do
A traditional 401(k) contribution comes out of your pay before federal and state income tax is figured, so it lowers those two. It does not lower Social Security or Medicare, which are charged on your full wages regardless. Put $10,000 into a 401(k) on that $100,000 salary and your federal income tax drops, but the $6,200 Social Security and $1,450 Medicare lines do not move. The tool treats a pretax deduction exactly this way, which is why the FICA figures hold steady when you add one.
How the state line works
For state income tax, you enter a single effective rate, applied to your wages after any pretax deduction. That keeps the tool honest for all fifty states without a rate table that drifts out of date every January. Nine states, including Texas, Florida, and Washington, take no tax on wage income at all, so you enter 0. For a state with its own brackets, your approximate effective rate gets you a close estimate of the net.
What this does not cover
This estimates federal withholding plus FICA and a flat state rate. It is not a pay stub. Real withholding depends on the entries on your W-4, and a paycheck can also carry local city taxes, benefit premiums beyond your pretax figure, wage garnishments, and employer-specific items none of which a general calculator can know. It also assumes salaried wage income, not self-employment, where both halves of FICA apply.
None of this is financial or tax advice. It shows the gross-to-net path so you can see roughly what reaches your account and why. For the exact numbers, your pay stub and a tax professional are the authorities.
Frequently asked questions
How much of a $100,000 salary do I take home? A single filer on $100,000 with no pretax deductions and no state income tax keeps $79,180 for 2026, which is $3,045.38 across 26 biweekly paychecks. That is after $13,170 of federal income tax, $6,200 of Social Security, and $1,450 of Medicare, a 20.8% total tax rate. A state income tax would lower it further.
How is take-home pay calculated? Take-home pay is gross salary minus pretax deductions, federal income tax, Social Security, Medicare, and state income tax. Social Security is 6.2% and Medicare is 1.45% of wages, together called FICA. Federal income tax uses the brackets on your income after the standard deduction. What is left is your net pay.
Why does Social Security stop at a certain income? Social Security tax applies only to wages up to an annual cap, the wage base, which is $184,500 for 2026. Above that, no more Social Security is withheld, so the most an employee pays into it in 2026 is $11,439. Medicare has no cap and actually adds 0.9% on wages above $200,000 for a single filer.
Do 401(k) contributions lower my taxes? A traditional 401(k) contribution lowers your federal and state income tax, because it comes out of pay before income tax is figured. It does not lower Social Security or Medicare, which are charged on your full wages. That is why a pretax deduction cuts income tax but leaves the FICA lines unchanged in this calculator.
Does this handle state taxes? You enter your state income tax as an effective percentage, so the tool works for any state without a rate table that goes stale. Enter 0 for the nine states with no wage income tax, such as Texas, Florida, and Washington. For a state with brackets, use your approximate effective rate for a close estimate.
Is this my exact paycheck? It is a close estimate of federal withholding plus FICA and a flat state rate, not an exact pay stub. Real paychecks also reflect your W-4 entries, local taxes, benefit premiums, and employer-specific items. Use it to understand the gross-to-net path and roughly what lands in your account, then check your actual stub for the precise figures.
