Gross-Up Calculator
Enter the take-home you want and we'll solve for the gross salary. Handles 2024, 2025, and 2026 federal brackets, FICA to the Social Security wage base, Additional Medicare over high-income thresholds, and pre-tax 401(k) and HSA reductions.

Gross needed for a target take-home (2026, single)
Approximate gross salary required to net common take-home amounts — single filer, standard deduction, federal income tax + FICA only. The "gross-up factor" is how much more than your target net the gross must be. A state with income tax pushes the gross higher.
| Target take-home | Gross salary needed | Gross-up factor |
|---|---|---|
| $50,000 | $59,515 | 1.19× |
| $75,000 | $94,058 | 1.25× |
| $100,000 | $129,822 | 1.30× |
| $150,000 | $201,457 | 1.34× |
The factor rises with income because higher earnings are taxed in higher brackets — though Social Security stops at the $176,100 wage base, which slightly flattens it at the top.
Worked example — bonus grossed up to net $10,000
An employer wants an employee to net exactly $10,000 from a bonus. The employee is in the 22% federal bracket and pays 6.2% Social Security + 1.45% Medicare = a combined marginal wedge of about 29.65%.
gross ≈ $10,000 ÷ (1 − 0.2965) = $14,215
So roughly $14,200 of gross bonus is needed. The flat-rate shortcut assumes one bracket; the calculator above solves it iteratively against the full progressive schedule, which is more accurate when the bonus pushes you across a bracket edge.
When to use a gross-up
Bonus payments
Your employer promises a $10k bonus "after tax." They gross it up so the check covers federal withholding and FICA and you net $10k.
Salary negotiation
You know you need $6,500/month net to cover expenses. Work backwards to figure out what gross salary to ask for.
Relocation reimbursement
Moving expenses paid by an employer are taxable since TCJA. Employers gross up the reimbursement so you aren't out of pocket for the tax.
Expat tax equalization
International assignments often promise the employee keeps their home-country net. The employer grosses up the foreign-country payroll to hit that net.
Frequently asked questions
What is a gross-up calculation?
A gross-up works backwards from a target take-home (net) to the gross pay needed so that after federal tax, FICA, and any pre-tax deductions, the net matches the target. Employers use it for bonus payments, relocation reimbursements, or expat tax equalization so the employee nets a specific figure.
How do you calculate a gross-up?
There is no single formula because the effective tax rate depends on total annual income, filing status, and any pre-tax deductions. This calculator uses an iterative solver: it tries gross amounts, runs each through the 2025/2026 IRS tax brackets + 6.2% Social Security to the $176,100 wage base + 1.45% Medicare, and converges on the gross that nets your target within $1.
Does a gross-up include state and local tax?
This calculator solves for federal income tax and FICA only. State and local withholding vary — if you live in a state with income tax, the actual gross needed to hit your target net will be higher. For state-aware paycheck math, check the linked state bracket calculators.
Why does my employer gross up a bonus?
To give you a specific net amount. If the employer wants you to net $5,000 from a bonus, they can't just write a $5,000 check — FICA and federal withholding apply. The gross-up adds enough extra so that after the mandatory withholding the net equals $5,000. The IRS supplemental wage rate (22% flat up to $1M) often applies to bonuses; this calculator uses your regular-wage marginal rate, which is usually closer to what you'll owe after you file.
Is this the same as a reverse paycheck calculator?
Yes — "gross-up", "reverse paycheck", and "net to gross" calculators all solve the same problem: given the take-home, find the gross. This tool is the reverse of our paycheck calculator.
