Income split: tax, FICA & take-home
FICA payroll taxes
FICA is the employee share of Social Security and Medicare, withheld from your paycheck separately from federal income tax. These figures still exclude state and local tax.

Understanding federal tax brackets and payroll tax
The U.S. federal income tax system is progressive, which means your income is divided into layers called brackets, and each bracket's rate applies only to the slice of income that falls inside it. This calculator first subtracts the standard deduction for your filing status to get your taxable income, then walks that amount up through the 2025 brackets one layer at a time, taxing only the portion that lands in each. The breakdown table above shows that process slice by slice, and the tax amounts in it add up to the total on the "federal income tax" line.
The biggest misconception: your whole income is not taxed at your top rate
Ask most people what it means to be "in the 22% bracket" and they will tell you that 22% of their income goes to the government. That is not how it works. Being in the 22% bracket means only that your highest, or marginal, rate is 22%, and that rate applies only to the dollars above the point where the 22% band begins. Every dollar below that threshold is still taxed at the lower 10% and 12% rates it passed through on the way up. No raise, bonus, or side gig can ever pull your earlier income into a higher rate: only the new dollars that actually cross the line are taxed at the higher rate.
Marginal rate versus effective rate
These two numbers answer different questions. Your marginal rate is the rate on your next dollar: it tells you how much tax a raise or extra freelance work will cost, the right number for "should I take on this" decisions. Your effective rate is your total federal income tax divided by your gross income, describing your actual overall burden across all brackets combined. Because the lower brackets are always taxed at their own lower rates first, your effective rate is always lower than your marginal rate, usually by a wide margin. A single filer in the 22% marginal bracket commonly has an effective rate closer to 10% to 11%.
How the standard deduction fits in
You are not taxed on your full paycheck. The standard deduction is a flat amount the IRS lets you subtract from gross income before any brackets apply, so it comes off the top and is effectively taxed at 0%. For 2025 it is $15,000 for single filers and $30,000 for married couples filing jointly. A single person earning $75,000 therefore starts climbing the brackets at $60,000, not $75,000. The deduction is why your taxable income (what the brackets actually see) is always smaller than your gross income, and it is the first thing this calculator computes.
A worked example: single filer, $75,000
Use the default inputs: Single, $75,000 gross. Subtract the $15,000 standard deduction and taxable income is $60,000. Watch that $60,000 climb the three brackets it reaches:
- 10% bracket (first $11,925): taxed at 10% = $1,192.50.
- 12% bracket ($11,925 up to $48,475, a span of $36,550): taxed at 12% = $4,386.00.
- 22% bracket ($48,475 up to $60,000, the final $11,525): taxed at 22% = $2,535.50.
Add the three pieces: $1,192.50 plus $4,386.00 plus $2,535.50 equals $8,114.00, exactly the figure on the "federal income tax" line and the total at the bottom of the breakdown table. The marginal rate is 22%, the top band reached. The effective rate is $8,114 divided by $75,000, or about 10.8%, roughly half the marginal rate. On top of income tax, FICA on the full $75,000 comes to about $5,738 (Social Security of $4,650 plus Medicare of $1,087.50). Landing "in the 22% bracket" does not mean handing over 22% of your pay.
What FICA is, and how it differs from income tax
Most workers pay a second federal tax that has nothing to do with the brackets above: FICA, the employee share of Social Security and Medicare, withheld automatically. Unlike income tax, it ignores the standard deduction and applies to your gross wages from the first dollar. Social Security is 6.2%, but only on wages up to the annual wage base ($176,100 for 2025), so it stops growing once wages pass that cap. Medicare is 1.45% on all wages with no cap. High earners owe an Additional Medicare Tax of 0.9% on wages above $200,000 (single) or $250,000 (married filing jointly). Your employer quietly pays a matching amount you never see. The "estimated take-home" line subtracts both income tax and your FICA share from gross income.
Common mistakes to avoid
- Confusing marginal and effective rate. Use the effective rate to judge your real burden, and the marginal rate only to judge the next dollar.
- Forgetting FICA when estimating take-home. Income tax is only part of your federal withholding. In the example above, FICA added about $5,738. Leave it out and your take-home estimate will be too high.
- Thinking a raise into a new bracket cuts your net pay. It cannot. Only the dollars above the threshold are taxed at the higher rate, so a raise always leaves you with more in hand, never less.
- Ignoring state and local tax. Many states and some cities levy their own income tax, which this tool does not include. Your true total burden can be meaningfully higher than the federal figure shown here.
What this estimate leaves out
This is a 2025 federal estimate, not a filing-ready return. It does not include state or local income tax, tax credits (such as the Child Tax Credit or education credits, which reduce tax dollar for dollar), itemized deductions that might beat the standard deduction, or other income types such as long-term capital gains, dividends, or self-employment income, which follow their own rules. Pre-tax 401(k) or HSA contributions would also lower the taxable figure. Treat the result as a starting point, verify current brackets at irs.gov, and remember this is an educational tool, not tax advice.
Frequently asked questions
Does being in the 22% bracket mean I pay 22% of all my income?
No. The 22% is your marginal rate, the rate on your top dollars only. The income below each threshold is still taxed at the lower 10% and 12% rates it passed through first. That is why a single filer in the 22% bracket usually has an effective rate closer to 10% to 11% of gross income.
What is the difference between my marginal rate and my effective rate?
Your marginal rate is the rate on your next dollar earned, useful for deciding whether extra work or a bonus is worth it. Your effective rate is your total federal income tax divided by your gross income, which describes your real overall burden. The effective rate is always the lower of the two.
Why is my taxable income lower than what I earn?
Because the standard deduction comes off the top before any brackets apply. For 2025 it is $15,000 for single filers and $30,000 for married couples filing jointly. A single person earning $75,000 has $60,000 of taxable income, so the brackets only ever see that smaller number.
Is FICA the same as federal income tax?
No, it is a separate tax. FICA is the employee share of Social Security (6.2% up to the $176,100 wage base) and Medicare (1.45% on all wages, plus 0.9% more above $200,000 single or $250,000 joint). It applies to your gross wages, ignores the standard deduction, and is withheld on top of income tax.
Will a raise that pushes me into a higher bracket reduce my take-home pay?
No. Only the portion of your income above the new threshold is taxed at the higher rate. Every dollar below it keeps its lower rate, so a raise always increases your net pay. The idea that crossing a bracket cuts your paycheck is a myth.
