Your take-home pay (net pay) is your gross salary minus federal taxes, state taxes, FICA (Social Security and Medicare), and voluntary deductions. On a $60,000 salary paid semi-monthly, gross per paycheck is $2,500. After all deductions, take-home pay is typically $1,900–$2,050 — a 20–24% reduction. Most employees never check whether their paycheck stub is actually correct, but understanding each deduction puts you in control of your cash flow.

What Is a Paycheck Calculator?
A paycheck calculator is a tool that computes your net take-home pay from your gross salary or hourly wage. It accounts for every mandatory and voluntary deduction on your paycheck: federal income tax withholding, Social Security tax, Medicare tax, state income tax, and any pre-tax benefit contributions such as 401(k) or health insurance premiums.
The calculator takes your gross pay, filing status (single, married, head of household), pay frequency (weekly, bi-weekly, semi-monthly, monthly), state of residence, and any pre-tax deductions as inputs. It then applies the current IRS withholding tables and your state's tax rates to estimate the exact amount you will receive after all deductions.
This is useful for several reasons. Before accepting a job offer, you can model your actual take-home pay rather than just the salary number. When adjusting your 401(k) contribution or health insurance tier, you can see the real impact on your paycheck before making changes. If you received a large tax refund or owed money at tax time, you can adjust your W-4 withholding and verify the effect immediately.
For most middle-income earners, take-home pay is 65–80% of gross salary. The gap is larger in high-tax states like California and New York, and smaller in states with no income tax like Texas, Florida, and Nevada.
How to Use the Paycheck Calculator
- Enter your gross salary. Annual salary, or the gross amount per pay period.
- Select your pay frequency. Weekly (52 per year), bi-weekly (26), semi-monthly (24), or monthly (12).
- Enter your filing status and allowances. Single, Married Filing Jointly, Head of Household. Add the number of dependents claimed on your W-4.
- Enter pre-tax deductions. 401(k) contributions, health insurance premiums, HSA contributions, and dependent care FSA — all reduce your taxable income.
- Enter your state. State income tax rates vary from 0% (Texas, Florida, Nevada, etc.) to over 13% (California).
- Read the breakdown. The calculator shows each line item: gross pay, federal income tax, Social Security, Medicare, state tax, pre-tax deductions, and your final net pay per paycheck and annually.
The pre-tax deduction section is where most people miss tax savings. Maximizing 401(k) contributions reduces both federal and state income taxes. Health insurance premiums through employer plans are pre-tax, saving you the marginal tax rate on those dollars.
How Paycheck Deductions Work
Gross pay is your starting number — salary ÷ pay periods, or hourly rate × hours worked.
Federal income tax is withheld based on your W-4 filing status and the IRS withholding tables. It is not a flat percentage — it is a marginal tax calculation. For 2024, the brackets are: 10% on income up to $11,600, 12% up to $47,150, 22% up to $100,525, 24% up to $191,950, and higher rates above that (for single filers).
FICA taxes are:
- Social Security: 6.2% of gross wages up to $168,600 (2024 wage base)
- Medicare: 1.45% of all wages (plus 0.9% additional Medicare tax on wages above $200,000 for single filers)
State income tax depends on your state. Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
Pre-tax deductions reduce taxable income:
- 401(k) / 403(b) contributions
- Traditional IRA payroll deduction
- Health insurance premiums (employer-sponsored)
- HSA contributions
- Dependent care FSA
Post-tax deductions come after taxes:
- Roth 401(k) contributions (post-tax)
- Life insurance premiums
- Wage garnishments
- Union dues
Worked example — $75,000 salary, single, semi-monthly paycheck:
| Deduction | Per Paycheck | Annual | |-----------|-------------|--------| | Gross pay | $3,125.00 | $75,000 | | Federal income tax | −$468.00 | −$11,232 | | Social Security (6.2%) | −$193.75 | −$4,650 | | Medicare (1.45%) | −$45.31 | −$1,087 | | State tax (CA ~5.5%) | −$171.88 | −$4,125 | | 401(k) 6% pre-tax | −$187.50 | −$4,500 | | Health insurance | −$125.00 | −$3,000 | | Net take-home | $1,933.56 | $46,405 |
Effective total deduction rate: 38.1% of gross. Take-home pay represents 61.9% of gross salary.
Frequently Asked Questions
What is the difference between gross and net salary? Gross salary is your total compensation before any deductions — what your offer letter says. Net salary (take-home pay) is what you actually receive after all tax withholding and deductions. The gap between them depends on your tax bracket, state, filing status, pre-tax benefits, and voluntary deductions. For most employees, net pay is 65–80% of gross pay.
Why might my paycheck be different from the calculator estimate? Several factors cause variation: overtime or bonuses (taxed at a higher supplemental rate of 22% federally), changes to pay frequency, additional withholding you requested on your W-4, varying health insurance or 401(k) contributions, or mid-year changes to tax bracket thresholds. The calculator provides an estimate; your actual paycheck depends on your employer's specific payroll calculations and any year-to-date adjustments.
How do I change my withholding amount? Submit a new W-4 to your HR or payroll department. The 2020+ W-4 no longer uses "allowances" — it uses a direct dollar approach. If you had a large tax refund last year, you are over-withholding; request less tax withheld by claiming the additional income or reducing additional withholding. If you owed taxes, increase withholding by claiming less or adding an additional dollar amount per paycheck.
Are bonuses taxed differently? Yes. The IRS considers bonuses "supplemental wages." Employers can withhold federal income tax on bonuses at a flat 22% (supplemental wage withholding rate) up to $1 million. For bonuses over $1 million, the rate jumps to 37%. Some employers aggregate the bonus with the regular paycheck and withhold at your effective rate. Either way, state taxes also apply. You may get a partial refund at tax time if the withholding rate was higher than your marginal rate.
What happens to Social Security tax if I earn more than $168,600? The Social Security wage base ($168,600 in 2024) caps how much of your income is subject to the 6.2% Social Security tax. Income above this amount is not subject to Social Security tax — but it is still subject to Medicare (1.45%) and the additional 0.9% Medicare surtax on wages above $200,000. High earners effectively see their FICA burden drop as a percentage of income once they cross the Social Security wage base.
