Gross pay is what you earn before deductions. Net pay is what reaches your account after taxes, benefits, retirement contributions, and other withholdings. The gap is not a mistake; it is the result of the payroll settings and your situation.
Common deductions
Payroll may withhold federal and state taxes, Social Security, Medicare, health premiums, retirement contributions, flexible spending, and other elected items. Not every employee has the same list.
Why withholding is not final tax
Withholding is a payment toward an eventual tax bill. A refund or balance due depends on the full year's income, deductions, credits, filing status, and tax rules, not only one paycheck.
Use estimates responsibly
Enter the pay frequency and deductions that match the offer or pay stub. Revisit the estimate after a raise, benefit change, move, or updated tax form. A calculator is not a tax return.
A worked example
Worked example: a $2,000 gross paycheck can have different net pay after retirement, health premiums, and tax withholding are applied. Two workers with the same gross pay can therefore receive different deposits.
Use a pay stub to replace assumptions and check the result after a benefits or tax-form change. Keep withholding separate from the final tax outcome for the year.
A useful comparison starts with the same pay period and the same elected benefits. Keep voluntary retirement or insurance deductions visible because they reduce take-home pay but may still increase long-term value.
Use gross pay to compare compensation and net-pay estimates to plan cash flow, keeping the distinction between withholding and final tax clear.
COMMON QUESTIONS
Frequently asked questions
Why did my net pay change if my salary did not?
Benefits, retirement contributions, tax forms, pay frequency, and year-to-date payroll limits can change deductions.
Can a paycheck calculator determine my tax refund?
No. It can estimate withholding and take-home pay, but the final result requires the complete tax-year information.
