Calculate your take-home pay
Understanding Net Pay vs. Gross Salary
When reviewing job offers or annual raises, there is often a noticeable gap between headline annual compensation (gross salary) and actual bank deposits on payday (net take-home pay). Mandatory tax withholdings and voluntary employee benefit choices affect how much money reaches your account each pay period.
Steps in the Payroll Deduction Process
A typical payroll engine applies deductions in a strict chronological sequence:
- Gross Earnings: The total agreed salary earned per period prior to any withholdings.
- Pre-Tax Deductions: Elective contributions such as traditional 401(k) accounts, Health Savings Accounts (HSA), Flexible Spending Accounts (FSA), and pre-tax health insurance premiums are subtracted first, reducing overall federal and state taxable income.
- FICA Payroll Taxes: mandatory Social Security taxes (6.2% up to the 2026 cap of $184,500) and Medicare taxes (1.45% baseline, plus an additional 0.9% tax on high earners) are computed on eligible wage bases.
- Federal Income Tax: Calculated on taxable wages after applying the 2026 standard deduction ($16,100 for Single, $32,200 for Married Filing Jointly, and $24,150 for Head of Household) across progressive tax rate brackets ranging from 10% to 37%.
- State and Local Taxes: Regional income tax withholdings are assessed based on local municipal rules or estimated flat state tax percentages.
Marginal Tax Brackets vs. Effective Tax Rates
A common misconception is that moving into a higher tax bracket reduces overall take-home earnings. The U.S. federal income tax system uses progressive marginal tax rates, meaning higher percentage rates apply only to income dollars earned within that specific income tier, rather than retroactively taxing all earnings at the maximum rate. Consequently, your effective (average) tax rate remains significantly lower than your top marginal rate bracket.
Strategies to Optimize Paycheck Withholdings
- Leverage Pre-Tax Accounts: Allocating funds toward health savings accounts (HSAs) or retirement funds reduces your current taxable income threshold, lowering federal taxes.
- Adjust Form W-4: Ensure your Form W-4 on file with your employer accurately reflects your household filing status, dependent credits, and additional income sources to minimize overpayment or unexpected tax bills.
Frequently asked questions
Which tax year does this calculator use?
It uses 2026 federal brackets, the 2026 standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household) and the 2026 Social Security wage base of $184,500.
Why is my real paycheck different from this estimate?
Payroll systems also account for W-4 settings, credits, local taxes, benefits, bonuses and state-specific rules. Treat this result as a close estimate, not an exact paycheck.
Does a 401(k) contribution reduce my taxes?
Traditional 401(k) contributions lower your federal and most state taxable income, but they do not reduce Social Security or Medicare wages. Roth 401(k) contributions do not lower current taxes.
How should I enter state tax?
Look up your state’s income tax rate or use your effective rate from last year’s return. Enter 0 for states without wage income tax, such as Texas, Florida and Washington.
