A net to gross paycheck calculator works backward from the take-home amount you want to the gross pay you must run through payroll. This is also called a gross-up calculator, and employers use it constantly — to make sure a bonus, relocation payment, or signing incentive lands at a specific net figure after taxes. Enter the desired take-home below and this reverse paycheck calculator returns the required gross using two methods: the flat 22% supplemental method and a bracket-accurate method that iterates the real 2026 tax tables.
Normally payroll runs from gross to net: you start with a salary and subtract taxes. A gross-up reverses that. You decide the exact net you want an employee to receive — say a $5,000 take-home bonus — and solve for the gross that, after withholding, leaves precisely $5,000. Employers gross up bonuses, relocation reimbursements, and award payments so the recipient is not shortchanged by taxes.
For bonuses and other supplemental wages, the IRS allows a flat 22% federal withholding rate. The gross-up formula is simply: gross = net ÷ (1 − total tax rate), where the total rate is 22% federal + 7.65% FICA + your state rate. For a $5,000 net bonus with a 5% state rate:
| Step | Value |
|---|---|
| Desired net | $5,000.00 |
| Total tax rate (22% + 7.65% + 5%) | 34.65% |
| Required gross = $5,000 ÷ (1 − 0.3465) | $7,651.11 |
| Total withheld | $2,651.11 |
| Verify net ($7,651.11 × 0.6535) | $5,000.00 ✓ |
So to hand an employee $5,000 in their pocket, payroll must process a gross bonus of $7,651.11 under the flat method.
The flat method overshoots for ordinary salary because real tax brackets are progressive — lower portions of income are taxed at 10% and 12%, not a flat 22%. For regular wages our calculator iterates: it tries a gross figure, computes the true 2026 federal tax (bracket by bracket), FICA, and state tax, checks the resulting net, and uses binary search to converge on the exact gross that hits your target. For a $70,000 annual take-home goal (single, 5% state), the required gross is about $93,604, verified to return $70,000 net.
| Target annual net | Required gross (single, 5% state) |
|---|---|
| $50,000 | ~$64,400 |
| $70,000 | ~$93,604 |
| $90,000 | ~$123,500 |
An employer wants a new hire to net exactly $10,000 from a signing bonus. Using the flat method with a 6% state rate: total rate = 22% + 7.65% + 6% = 35.65%; required gross = $10,000 ÷ 0.6435 = $15,540.02. The employer processes $15,540.02 gross; after $5,540.02 in combined withholding, the employee receives $10,000.
A gross-up is only as accurate as the tax rates you include. FICA (7.65%) applies to virtually all wages up to the Social Security wage base ($184,500 in 2026), and state income-tax rates range from 0% (no-tax states) to over 13% (California top bracket). Omitting state tax in a high-tax state would leave the employee short. The calculator lets you set your exact state rate.
Real payroll can differ slightly because of year-to-date Social Security caps, additional Medicare tax over $200,000, local taxes, pre-tax benefit elections, and W-4 settings. The flat method also assumes the bonus is withheld at the 22% supplemental rate, which is the standard employer practice but not the only allowed method. Treat the output as a close estimate and confirm with your payroll system for exact figures.
Gross-up is most common in three employer scenarios. Relocation packages are frequently grossed up so a promised $15,000 of moving assistance actually nets $15,000 after the IRS treats it as taxable income. Sign-on bonuses are grossed up when an offer letter promises a specific net amount. Awards and prizes (spot bonuses, referral rewards) are grossed up so the recipient is not surprised by a smaller-than-expected check. In each case, the employer runs the net-to-gross math, processes the larger gross, and absorbs the extra cost.
Using the flat supplemental method with 22% federal + 7.65% FICA and a 5% state rate (34.65% total), here is the gross required for common net targets:
| Desired net | Total tax rate | Required gross |
|---|---|---|
| $1,000 | 34.65% | $1,530.22 |
| $2,500 | 34.65% | $3,825.55 |
| $5,000 | 34.65% | $7,651.11 |
| $10,000 | 34.65% | $15,302.22 |
Change the state rate in the calculator to recompute for your state — a no-income-tax state lowers the total rate to 29.65% and the required gross with it.
The flat 22% method assumes every dollar is taxed at the supplemental rate. That is correct for a separately paid bonus, but for regular salary it overstates tax, because the progressive brackets tax the first $12,400 at 10% and the next band at 12% (single, 2026). For an annual salary target, the bracket-accurate method in our calculator returns a smaller, more realistic gross. Example: to net $50,000 a year (single, 5% state), the bracket method needs about $64,400 gross, whereas naively applying a flat 34.65% would demand about $76,500.
For regular wages, there is no simple closed-form formula because tax is piecewise across brackets. The calculator uses binary search: it guesses a gross, computes the exact 2026 federal tax tier by tier plus FICA and state tax, checks whether the resulting net is above or below your target, and narrows the range until it converges to the cent. This mirrors how professional payroll software solves gross-up for salaried employees and is far more accurate than a single flat rate.
Employers often ask whether to gross up at the flat 22% or aggregate (bracket) method. For a one-time bonus paid separately, the flat method matches IRS supplemental-withholding rules and is simplest. For setting a base salary to a net target, the bracket method is more accurate. Whichever you choose, document the assumed state rate and any local taxes, and verify the final figure in your payroll system, since year-to-date caps and W-4 settings can move the exact result.
Hourly employees sometimes need the reverse calculation too — for example, figuring what hourly rate produces a target weekly take-home. The same principle applies: estimate total withholding (federal, FICA, state), then divide your desired net by (1 − total rate) to get required gross, and divide by hours to get the rate. For a $1,000 weekly net at a 30% effective rate, required gross is about $1,429, or roughly $35.70/hour for a 40-hour week. The flat method works for quick estimates; for precise annual figures, the bracket-accurate method accounts for progressive taxation.
Gross-up is not limited to cash. Employers sometimes provide taxable non-cash benefits — a gift, an award trip, or taxable relocation services — and gross up the employee's pay to cover the resulting tax so the benefit is effectively tax-free to the worker. The mechanics are identical: determine the taxable value, apply the gross-up formula, and add the extra gross to the paycheck. This is common for executive perks and relocation, where the employer wants the stated benefit value to reach the employee without tax erosion.
For high earners, the Social Security portion of FICA (6.2%) stops once year-to-date wages exceed the 2026 wage base of $184,500. Above that point, the effective tax rate on additional pay drops, so a year-end bonus paid to someone already over the cap needs a smaller gross-up than the same bonus earlier in the year. The flat 7.65% FICA assumption slightly overstates the gross required for employees already past the Social Security cap; for those workers, use a 1.45% FICA assumption (Medicare only) for more accuracy.
For the most accurate result, enter figures straight from your own documents rather than estimates. Pull your gross pay and pay frequency from a recent pay stub, your filing status from your most recent tax return, and any pre-tax deductions (retirement, health, HSA) from your benefits enrollment. Small differences in these inputs — especially filing status and pre-tax contributions — can change your take-home by hundreds or thousands of dollars a year. The calculator uses verified 2026 federal brackets, the $184,500 Social Security wage base, and current state rules, so matching its inputs to your actual situation gives a reliable estimate you can plan around. Always treat the output as an educated estimate and confirm exact figures against your payroll provider or a tax professional, since year-to-date caps, local taxes, and W-4 elections can shift the final number.
Tax brackets, standard deductions, the Social Security wage base, and several state rates all change yearly. Using a calculator built on the correct 2026 numbers — rather than a prior-year tool — matters because the differences compound across a full year of pay. This page reflects the 2026 federal standard deductions ($16,100 single / $32,200 joint / $24,150 head of household), the 2026 bracket thresholds, the $184,500 Social Security wage base, and the latest published state rates. When the IRS and state agencies announce the following year's figures, the inputs here will be updated so your estimate stays current.
It is a reverse paycheck tool that starts from the take-home (net) amount you want and solves for the gross pay required so that, after federal tax, FICA, and state tax are withheld, the employee receives exactly that net. Employers call this a gross-up.
Use the flat-rate formula: gross = net ÷ (1 − total tax rate), where the total rate is the 22% federal supplemental rate plus 7.65% FICA plus your state rate. For a $5,000 net bonus with a 5% state rate, the total rate is 34.65% and the required gross is about $7,651.11.
Because regular wages are taxed progressively — the first dollars are taxed at 10% and 12%, not a flat 22%. The bracket-accurate method computes the real 2026 tax tier by tier, so for ordinary salary it needs a smaller gross to reach the same net than the flat supplemental method.
About $93,604 for a single filer in 2026 with a 5% state income-tax rate, using the bracket-accurate method. The exact figure depends on your filing status and state rate, which the calculator lets you set.
Yes. An accurate gross-up must include FICA (7.65% up to the $184,500 Social Security wage base) and your state income-tax rate, which ranges from 0% in no-tax states to over 13% in California. Omitting them would leave the employee short of the target net.
It is a close estimate. Real payroll can vary slightly due to year-to-date Social Security caps, the 0.9% additional Medicare tax over $200,000, local taxes, pre-tax benefits, and W-4 settings. Confirm the final figure in your payroll system.
