Net Income Calculator

Net income here means personal take-home pay: what lands in your account after tax and deductions come out of your gross salary. (Confusingly, in company accounting the same phrase means a business’s bottom-line profit. This page is about a paycheck.)

Taxable income = Gross salary − Pre-tax deductions Net income = Gross − Federal tax − State tax − Social Security − Medicare − All deductions

What each piece means:

• Federal tax runs from 10% to 37% by bracket. Most people land between 12% and 24%. Enter your effective rate, not your top bracket, since only the last slice of income is taxed at the top rate.
• State tax ranges from nothing to 13.3% in California. Nine states charge no income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming.
• Social Security, part of FICA (the Federal Insurance Contributions Act), takes 6.2% up to an annual wage base that is indexed and rises every year. This calculator uses $184,500, the 2026 figure. Earnings above it are not charged. Check the current year’s figure at ssa.gov if precision matters.
• Medicare takes 1.45% with no cap, plus an extra 0.9% on everything above $200,000 for a single filer. Both are applied here.
• Pre-tax deductions (401(k), 403(b), most health premiums, HSA and FSA) come out before income tax is worked out, so they cut your tax bill as well as your pay.
• After-tax deductions (Roth 401(k), union dues, garnishments) come out of money already taxed.

Why the pre-tax box is separate

This is the single most valuable thing on the page. Put $400 a month into a 401(k) and at a combined 27% tax rate that $4,800 costs you about $3,504 of take-home pay, because $1,296 of it would have gone to tax anyway. Put the same $400 into a Roth or a savings account after tax and the full $4,800 comes out of your pocket. Same money saved, different cost.

One wrinkle worth knowing: pre-tax retirement contributions reduce income tax but not Social Security or Medicare. Those are charged on the full gross, which is why the calculator applies them before the pre-tax subtraction.

Monthly and biweekly: Net Monthly = Annual Net ÷ 12 Net Biweekly = Annual Net ÷ 26

There are 26 biweekly periods in a year, not 24, so biweekly pay is not simply half the monthly figure.

Worked example: a $75,000 salary, 22% federal, 5% state, no pre-tax deductions. Federal $16,500, state $3,750, Social Security $4,650, Medicare $1,088. Net annual $49,013, about $4,084 a month.

Now add $400 a month of pre-tax contributions. Taxable income drops to $70,200, income tax falls from $20,250 to $18,954, and take-home lands at $3,792 a month.

Look at what that trade actually was. You put $4,800 into the retirement account for the year, and your take-home fell by $3,504. The other $1,296 came out of the tax bill instead of out of you.
