Net-to-Gross Salary Calculator
Before you negotiate a salary, you need to know what gross pay actually produces the take-home you want. FICA takes 7.65% of every dollar up to the Social Security wage base — so if you want to bring home $3,000 per biweekly paycheck, you need to ask for more than $3,000 ÷ (1 − 0.0765). Enter your target take-home and see the gross salary that gets you there.
Informational only — not financial advice. Covers FICA (Social Security & Medicare) only; does not calculate federal or state income tax withholding. Your actual required gross will be higher once income taxes are included.
Enter your target take-home to find the salary you need.
How this calculator works
The FICA math, inverted
The standard paycheck calculator goes gross → FICA → deductions → net. This tool runs it backwards: you supply the target net, and the calculator solves for the gross algebraically.
The employee FICA rate is 6.2% Social Security + 1.45% Medicare = 7.65% combined, subject to the 2026 SS wage base of $184,500 (SSA.gov).
Two regimes: below vs. above the SS cap
The algebra has two cases depending on whether the required gross puts annual wages below or above the Social Security wage base:
- Below cap: both SS and Medicare apply to all FICA-taxable wages. Combined FICA rate = 7.65%. Gross = (target net + total deductions − sec 125 × 7.65%) ÷ (1 − 7.65%).
- Above cap: SS is flat (employer has withheld the maximum); only Medicare (1.45%) continues to increase with wages. Gross = (target net + flat SS + total deductions − sec 125 × 1.45%) ÷ (1 − 1.45%).
The calculator solves the below-cap formula first. If the resulting per-period FICA wages exceed the per-period SS cap, it switches to the above-cap formula automatically.
Section 125 and pre-tax deductions
Pre-tax benefits (health, dental, vision, FSA, HSA contributions) under a Section 125 cafeteria plan reduce FICA-taxable wages per IRC § 3121(a)(5). The calculator accounts for this: entering pre-tax benefits reduces the FICA calculation, which in turn reduces the required gross.
401(k) pre-tax contributions reduce federal taxable income but do not reduce FICA-taxable wages (IRC § 3121(a)). They are treated as a straight deduction from gross without affecting the FICA base.
What this calculator doesn’t cover
Federal and state income tax withholding are not modeled. They depend on your W-4 elections, filing status, and state. For most employees, federal income tax withholding is the largest single deduction — the required gross shown here is a FICA-only floor. Your true required gross for a given net will be meaningfully higher.
Additional Medicare Tax (0.9%) applies when wages exceed $200,000/year. The calculator includes it in the per-period FICA breakdown for affected earners, but it does not affect the inversion formula materially for most salary ranges.

Frequently asked questions
How do I calculate the gross salary I need to reach a target take-home?
Because FICA rates are fixed percentages, you can solve algebraically: divide your target net by (1 minus the effective FICA rate). Below the Social Security wage base the combined employee FICA rate is 7.65%; above it only Medicare (1.45%) applies. This calculator handles both regimes automatically.
What gross salary gives me $5,000 per month take-home?
Assuming no pre-tax deductions and wages below the Social Security wage base ($184,500 in 2026): $5,000 ÷ (1 − 0.0765) ≈ $5,412 gross per month, or roughly $64,944 annually. FICA accounts for about $412 of the difference each month.
Why would I use a reverse paycheck calculator?
For salary negotiation. If you know the take-home you need to cover your expenses, working backwards to the required gross is more precise than guessing. It also helps you evaluate a job offer net of FICA before comparing two positions.
Does the gross-to-net math change above the Social Security wage base?
Yes. Above the $184,500 Social Security wage base (2026), the 6.2% SS tax no longer applies — only Medicare (1.45%) continues. High earners therefore need less gross to achieve the same net take-home. The calculator applies the correct rate for each income range.
