Every paycheck is the result of a series of withholdings applied to your gross wages. Understanding each deduction helps you verify your pay stub, adjust your W-4, and plan your budget accurately.

Standard deduction: $15,000 (single), $30,000 (married), $22,500 (head of household). Source: IRS Rev. Proc. 2024-40.
To calculate your net paycheck: (1) Start with gross pay for the period (annual salary ÷ pay periods per year). (2) Subtract pre-tax deductions like 401(k) and health insurance premiums. (3) Calculate federal income tax withholding using 2025 IRS brackets (10%–37%). (4) Subtract FICA: Social Security (6.2% up to $176,100) and Medicare (1.45%). (5) Subtract state income tax (0%–13.3% depending on state). Net pay = Gross pay − Federal tax − FICA − State tax − Pre-tax deductions. A $75,000 salary paid biweekly (26 checks/year) has a gross of $2,885 per paycheck; net pay is typically $1,950–$2,300 depending on state and filing status.
2025 federal tax brackets for single filers: 10% on $0–$11,925; 12% on $11,925–$48,475; 22% on $48,475–$103,350; 24% on $103,350–$197,300; 32% on $197,300–$250,525; 35% on $250,525–$626,350; 37% over $626,350. For married filing jointly, brackets are roughly doubled. The 2025 standard deduction is $15,000 (single), $30,000 (married), $22,500 (head of household). These are marginal rates — only income in each bracket is taxed at that rate, not all income.
The 2025 Social Security wage base is $176,100. This means Social Security tax (6.2%) is only withheld on the first $176,100 of wages. Once you earn more than $176,100 in a calendar year, Social Security withholding stops for that year. Medicare (1.45%) has no wage cap and applies to all earnings. High earners also pay an additional 0.9% Medicare surtax on wages above $200,000 (single) or $250,000 (married filing jointly).
On a $60,000 salary paid biweekly (26 checks/year), each gross paycheck is $2,308. Estimated deductions (single filer, Texas, no 401k): Federal tax ≈ $234/paycheck (effective rate ~10.4%); Social Security ≈ $143/paycheck (6.2%); Medicare ≈ $33/paycheck (1.45%); State tax: $0 (Texas has no income tax). Net paycheck ≈ $1,898. In a high-tax state like California at 9.3%, deduct another ~$215, bringing net to ~$1,683.
Biweekly pay = 26 paychecks per year (every two weeks — e.g., every other Friday). Semimonthly pay = 24 paychecks per year (twice a month — e.g., 1st and 15th). On a $70,000 salary: biweekly gross = $2,692/paycheck; semimonthly gross = $2,917/paycheck. Annual take-home is the same regardless of frequency, but individual paycheck amounts differ. Some biweekly employees receive 3 paychecks in certain months (2–3 times per year), which can feel like a "bonus" paycheck. Most salary workers prefer biweekly for budgeting consistency.
Yes. Traditional 401(k) contributions are pre-tax, meaning they reduce your federal and state taxable income. The 2025 401(k) contribution limit is $23,500 ($31,000 if age 50+). On a $80,000 salary in the 22% federal bracket, contributing 10% ($8,000/year) reduces federal tax by $8,000 × 22% = $1,760/year. Your paycheck decreases by $8,000/year, but your federal tax bill drops by $1,760 — so the real cost to take-home pay is only $6,240/year. Roth 401(k) contributions are after-tax (no current-year tax benefit but tax-free in retirement).
9 states have no state income tax in 2025: Alaska, Florida, Nevada, New Hampshire (eliminated interest/dividend tax as of 2025), South Dakota, Tennessee, Texas, Washington, and Wyoming. Living in a no-tax state can save $3,000–$15,000+ per year on a $100,000 salary compared to high-tax states. However, these states often have higher sales taxes, property taxes, or other fees to compensate for lost income tax revenue.
Your W-4 filing status determines how much federal income tax is withheld. Single: uses the single tax brackets, smaller standard deduction ($15,000 in 2025), higher withholding. Married Filing Jointly: uses wider brackets and larger deduction ($30,000), significantly lower withholding if only one spouse works. Head of Household: intermediate brackets ($22,500 deduction), for qualifying single parents. On a $70,000 salary: Single federal withholding ≈ $9,200/year; Married (one income) ≈ $5,100/year — a $4,100 annual difference that shows up as ~$158 more per biweekly paycheck for married filers.
This calculator uses 2025 federal tax brackets (IRS Rev. Proc. 2024-40) and the 2025 standard deduction. State income tax rates are approximations using top marginal rates — actual state taxes may vary based on individual state deductions, exemptions, and local taxes. Social Security wage base is $176,100 for 2025. This tool is for estimation purposes only and does not constitute tax advice. Consult a qualified tax professional or use IRS Publication 15-T for precise withholding amounts.
