Gross-Up Salary Calculator (Net to Gross)
Back into the gross salary that gets you the take-home you want.
Why "grossing up" isn't simple division
You might think a $60,000 target take-home just means adding back a flat percentage, but federal tax is progressive and FICA has its own rules — so the relationship between gross and net pay isn't linear. This tool solves it the way payroll systems do: it guesses a gross amount, computes the resulting net pay under 2024 brackets and FICA, compares it to your target, and adjusts — repeating until the numbers converge.
What's included and what isn't
The calculation includes federal income tax (2024 brackets, standard deduction) and FICA — 6.2% Social Security up to the $168,600 wage base, plus 1.45% Medicare with no cap. It does not include state or local income tax, which varies enormously (zero in some states, over 10% in others) — add your state's effective rate manually for a closer real-world number.
Not tax advice. Figures use the 2024 federal tax year and are estimates for general education only — every situation is different. Confirm your numbers with a CPA or tax professional, and check the current year's IRS figures, before filing or making financial decisions.
Frequently asked questions
Why does this need to 'solve' instead of just calculating directly?
Because federal tax brackets are progressive, the relationship between gross pay and net pay isn't a straight percentage — the marginal rate changes as gross pay rises. The calculator iterates toward the gross amount that produces your target net pay.
Does this include state income tax?
No. State income tax rates vary from 0% (in several states) to over 10%, so this tool covers only federal income tax and FICA. Add your state's effective rate manually if you want a closer real-world number.
Why is FICA included but not benefits or 401(k) contributions?
FICA (Social Security and Medicare) is a mandatory payroll tax with fixed 2024 rates, so it's straightforward to model. Benefits, retirement contributions and other payroll deductions vary too much by employer to build in generically.
Is the Social Security wage base the same every year?
No, it's adjusted annually. This calculator uses the 2024 wage base of $168,600 — above that amount, no further Social Security tax is withheld (Medicare has no such cap).
