Net Salary Calculator

The gap between your stated salary and the money that actually lands in your bank account can be surprising — sometimes startlingly so. Federal and state income taxes, Social Security and Medicare contributions, health insurance premiums, retirement contributions, and other withholdings can easily consume 25-40% of a gross paycheck, leaving you with significantly less than the annual salary figure you discussed during hiring. Understanding exactly what is deducted from your paycheck, why, and how to optimize your withholdings and deductions makes your compensation work harder for you.

Gross Pay vs. Net Pay

Gross pay is your total earnings before any deductions — the salary or wage amount agreed upon with your employer. For salaried employees, gross pay per paycheck is the annual salary divided by the number of pay periods (26 for biweekly, 24 for semi-monthly, 12 for monthly). For hourly employees, gross pay is hours worked multiplied by the hourly rate, plus any overtime (time-and-a-half or double-time for hours above the threshold). Net pay — your take-home pay — is gross pay minus all deductions: taxes withheld, benefits premiums, and voluntary retirement contributions.

The distinction matters for budgeting and financial planning. All budgeting, saving goals, and living expense calculations should be based on net pay, not gross salary. Many people make the mistake of budgeting based on their annual salary, then wondering why they can't meet their savings goals — they are working with a number that is 25-40% higher than the money actually available. Creating a budget from your net pay, not gross salary, is the foundation of realistic financial planning.

Federal Income Tax Withholding

Federal income tax is withheld from each paycheck based on your W-4 form elections and your paycheck amount. The W-4 was redesigned in 2020 to be more straightforward, replacing the old allowances system with direct specification of filing status, claimed dependents, and any additional withholding. The IRS withholding tables calculate the appropriate withholding based on these inputs and the paycheck amount. Claiming accurate information on your W-4 aims to have your total withheld amount closely match your actual tax liability, minimizing both large refunds (which represent an interest-free loan to the government) and large tax bills at filing time.

Federal income tax uses a progressive bracket system: the first portion of income is taxed at the lowest rate (10%), with incrementally higher rates on income in higher brackets. For 2024, the brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Importantly, only the income within each bracket is taxed at that bracket's rate — a person in the "24% bracket" does not pay 24% on all their income, only on the portion that falls within the 24% bracket range. Understanding marginal vs. effective tax rates is essential for accurate tax planning.

FICA Taxes: Social Security and Medicare

Federal Insurance Contributions Act (FICA) taxes fund Social Security and Medicare. Social Security tax is 6.2% of gross wages up to the wage base limit (,600 in 2024 — above this amount, no additional Social Security tax is withheld). Medicare tax is 1.45% of all wages, with no income cap. The employee pays these rates; the employer pays an equal matching amount (making the total contribution 12.4% for Social Security and 2.9% for Medicare). High earners also pay the Additional Medicare Tax of 0.9% on wages above ,000 (single) or ,000 (married filing jointly).

Self-employed individuals pay both the employee and employer portions of FICA — the self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) on net self-employment income, though they can deduct half of this from their taxable income. Understanding FICA is important for comparing employee vs. contractor compensation: a ,000 salary as an employee costs the employer approximately ,650 including the employer FICA share, while a ,000 independent contractor rate means the contractor pays both sides of FICA themselves.

Pre-Tax Benefits and Their Value

Many employer-provided benefits allow employee contributions to be deducted from gross pay before taxes are calculated — these are called pre-tax deductions. Traditional 401(k) contributions, health insurance premiums, FSA (Flexible Spending Account) contributions, HSA contributions, and commuter benefit contributions are all common pre-tax deductions. The tax benefit is substantial: a per month health insurance premium deducted pre-tax saves approximately -200 per month in taxes for someone in the 25-30% combined federal/state tax bracket.

Pre-tax benefits effectively reduce your taxable income before any taxes are calculated. This is why the "true cost" of employer benefits — and why evaluating total compensation rather than just salary is important — needs to account for the after-tax value of health insurance, retirement contributions, and other pre-tax benefits. A lower-salary job with generous pre-tax health insurance and retirement matching may provide higher after-tax compensation than a higher-salary job where you pay for health insurance and retirement savings entirely with after-tax dollars.

State and Local Income Taxes

State income taxes vary dramatically by location. Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax on wages. California has the highest top marginal rate at 13.3%. Most states with income tax have progressive brackets similar to federal taxes, though the rates and bracket thresholds differ widely. Nine states use a flat rate on all taxable income regardless of amount. Local income taxes (city or county taxes) apply in some jurisdictions, including New York City, Philadelphia, and various Ohio cities. The combined federal, state, and local marginal tax rate determines the true cost of earning an additional dollar of income and is the relevant rate for decisions like whether to put money in a traditional vs. Roth 401(k).
