How this paycheck calculator works
Understanding your true take-home pay is essential for budgeting, financial planning, and evaluating job offers. This paycheck calculator estimates your net annual income by subtracting federal income tax, state income tax, Social Security, and Medicare (FICA) from your gross salary.
What this calculator includes
- 2025 federal tax brackets — Progressive rates from 10% to 37% with standard deduction applied.
- State income tax — Simplified effective rates for all 50 states and Washington, D.C.
- FICA taxes — Social Security (6.2% up to $176,100 wage base) and Medicare (1.45% on all wages).
- Pretax deductions — 401(k), health insurance, HSA, and FSA contributions that reduce your taxable income.
The calculation process
- Start with gross annual salary — Your total compensation before any deductions.
- Subtract pretax deductions — Retirement contributions, health insurance premiums, HSA/FSA contributions.
- Calculate taxable income — Apply standard deduction for your filing status.
- Compute federal tax — Apply progressive bracket rates to taxable income.
- Compute state tax — Apply your state's effective rate.
- Compute FICA taxes — Social Security and Medicare on gross income (minus pretax deductions).
- Calculate net pay — Subtract all taxes from gross salary.
Federal income tax brackets
The United States uses a progressive federal income tax system, meaning higher portions of your income are taxed at higher rates. For 2025, the federal brackets range from 10% to 37%, with the thresholds varying by filing status.
Marginal vs. effective tax rate
- Marginal rate — The rate on your last dollar earned (your tax bracket).
- Effective rate — The percentage of your total income paid in taxes (always lower than marginal rate due to progressive structure).
Example: Single filer earning $75,000
| Income range | Rate | Tax on range |
|---|---|---|
| $0 - $11,600 | 10% | $1,160 |
| $11,600 - $47,150 | 12% | $4,266 |
| $47,150 - $75,000 | 22% | $6,127 |
| Total federal tax | $11,553 | |
| Effective federal rate | 15.4% | |
This calculator shows your effective rate across all taxes — federal, state, and FICA — so you can see the true percentage of your income going to taxes.
State income tax
State income tax rates vary widely. Nine states have no income tax, while others like California and New York have rates exceeding 6-10% for middle and high earners.
No-income-tax states (9 states)
- Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming
High-tax states (top rates)
- California — up to 13.3%
- New York — up to 10.9%
- New Jersey — up to 10.75%
- Hawaii — up to 11%
State-by-state comparison example
| State | Gross salary | State tax | Net annual |
|---|---|---|---|
| Texas (0%) | $75,000 | $0 | $58,247 |
| California (6%) | $75,000 | $4,500 | $53,747 |
If you live in a no-income-tax state, you will keep more of your paycheck compared to someone with the same salary in a high-tax state. Use the state dropdown to compare how different states affect your net pay. Keep in mind that some localities also impose city or county income taxes, which are not included here.

FICA taxes (Social Security and Medicare)
FICA taxes fund Social Security and Medicare. These are flat rates applied to your gross income, regardless of filing status or deductions (except pretax deductions reduce the FICA base).
2025 FICA rates and limits
| Component | Rate | Wage cap |
|---|---|---|
| Social Security | 6.2% | $176,100 |
| Medicare | 1.45% | No cap |
| Additional Medicare tax | 0.9% | $200,000 (single) / $250,000 (married) |
| Total FICA (standard) | 7.65% | — |
How FICA differs from income tax
- Not progressive — Everyone pays the same percentage (up to the Social Security wage cap).
- Wage base limit — Once your earnings exceed $176,100, you stop paying Social Security tax on the excess, which slightly increases your take-home percentage for very high earners.
- Additional Medicare tax — High earners pay an extra 0.9% Medicare tax on wages above the threshold.
This calculator accounts for the wage base and additional Medicare tax thresholds automatically.
Pretax deductions and how they lower your taxes
Pretax deductions are one of the most powerful tools for reducing your tax burden. When you contribute to a traditional 401(k), pay health insurance premiums through your employer, or fund an HSA, those amounts are subtracted from your gross income before taxes are calculated.
Common pretax deductions
- Traditional 401(k) contributions — Up to $23,000 annual limit (2025), plus $7,500 catch-up if 50 or older.
- Health insurance premiums — Employer-sponsored plans paid through payroll deduction.
- Health Savings Account (HSA) — $4,300 individual / $8,550 family (2025), plus $1,000 catch-up if 55 or older.
- Flexible Spending Account (FSA) — $3,200 healthcare FSA (2025), $5,000 dependent care FSA.
- Transit and parking benefits — Up to $315/month each (2025).
Tax savings example
| Scenario | Gross salary | Pretax deductions | Taxable income | Federal tax saved |
|---|---|---|---|---|
| Without deductions | $75,000 | $0 | $75,000 | — |
| With deductions | $75,000 | $7,000 | $68,000 | $1,540 |
At a 22% marginal federal rate, $7,000 in pretax deductions saves you roughly $1,540 in federal tax alone, plus additional savings on state tax and FICA. Maximizing pretax deductions is one of the easiest ways to keep more of your paycheck. Enter your total annual pretax deductions in the calculator to see the impact.
Comparing gross salary offers
When evaluating job offers, do not compare gross salaries alone — compare net take-home pay.
Factors that affect net pay
- State tax rates — A $75,000 offer in Texas (no state tax) may result in higher net pay than an $80,000 offer in California (high state tax).
- Pretax benefits — An offer with generous 401(k) match and employer-paid health insurance can yield more take-home than a higher gross salary with fewer benefits.
- Local taxes — Some cities (NYC, San Francisco) impose additional income taxes.
- Cost of living — Higher net pay matters less if housing and expenses are significantly higher.
How to compare offers
- Calculate net pay — Use this calculator for each offer's gross salary, state, and estimated pretax deductions.
- Factor in employer benefits — 401(k) match, health insurance premiums, HSA contributions, stock options.
- Adjust for cost of living — Use cost-of-living calculators to compare purchasing power across cities.
- Consider long-term value — Growth opportunities, work-life balance, career development.

Understanding your paycheck stub
Your actual paycheck stub will show gross pay, each tax and deduction line by line, and your net pay. Compare your stub against this calculator's output to verify your withholding is correct.
Common paycheck stub sections
- Earnings — Gross pay, overtime, bonuses, commissions.
- Pretax deductions — 401(k), health insurance, HSA, FSA.
- Taxes — Federal income tax, state income tax, Social Security, Medicare, local taxes.
- After-tax deductions — Roth 401(k), union dues, garnishments, charitable contributions.
- Net pay — Your take-home amount after all deductions.
Adjusting your withholding
If your real paycheck differs significantly from this calculator's estimate, check your W-4 form — you may be withholding too much or too little based on your elections. You can adjust your W-4 at any time to better match your actual tax liability and optimize your cash flow throughout the year.
When to update your W-4
- Major life events — Marriage, divorce, birth of a child, home purchase.
- Large tax refund or bill — If you consistently get a big refund, you are over-withholding. If you owe a lot, you are under-withholding.
- Income changes — New job, raise, bonus, or side income.
- Two-income households — Use the IRS W-4 calculator to optimize withholding across both spouses.
