Tax Delta and Cumulative Gain
Notes
- Multi-year projections hold 2026 federal and state brackets constant. Future bracket inflation indexing will shift the absolute numbers, but the directional gain is preserved.
Track Every Paycheck After the Raise
Pay44 handles overtime, bonuses, deductions, and 401(k) for all 50 states, so you can see what your new offer looks like on payday before signing. Download the app to plan it out.
Why Gross Numbers Mislead in a Salary Negotiation
A "$10,000 raise" looks the same on every offer letter, but it lands differently in the bank. Federal income tax, state income tax, Social Security, and Medicare all take a slice of every new dollar. In a high-tax state like California or New York, the marginal rate on a mid-career raise can sit between 35% and 45%. In a no-income-tax state like Texas or Florida, the same raise might keep 70% or more.
The headline mistake most negotiation guides make is reporting the gross raise alone, or the change in your average (effective) tax rate. Neither tells you how much of the new dollars you actually keep. The honest number is the marginal rate on the raise itself: 1 minus (net raise divided by gross raise). That single percentage answers the question every job candidate is asking: "How much of the increase is mine?"
State choice matters more than people expect. Identical $70,000 to $78,000 raises produce different net outcomes in California (state tax bracket adds about 6% to the marginal rate), New York (about 6.25%), and Texas or Florida (0%). If you are weighing a relocation as part of the offer, you can use our job offer comparator to model the full picture.
How the Salary Negotiation Calculator Works
The calculator runs both salaries through the same engine. For each scenario it computes federal income tax using the 2026 IRS brackets, state income tax using your state's 2026 bracket table (or flat rate, or zero for no-tax states), Social Security at 6.2% up to the 2026 wage base, and Medicare at 1.45% with the 0.9% Additional Medicare surtax above the filing threshold. Pre-tax 401(k) reduces federal and state taxable income but not FICA.
The four headline outputs are the ones that matter for negotiation prep: annual take-home increase, per-paycheck increase, marginal tax rate on the raise, and percent of the raise you keep. The secondary grid splits the tax delta into federal, state, and FICA so you can see which lever is actually moving. The 5-year and 10-year cumulative gain assumes both scenarios grow at the same future raise rate you enter, so the gap reflects the structural advantage of starting from a higher base.
All money math uses big.js for decimal precision, matching the conventions used across the rest of Pay44's calculators. For the underlying bracket detail, see our federal tax bracket calculator or the marginal vs. effective tax rate calculator.
A Worked Example: $70K to $78K in Three Different States
Same single filer, biweekly pay, no 401(k), 2026 brackets. The gross raise is $8,000 (11.4% of current) in every case.
| State | Gross Raise | Net Raise (annual) | Per Paycheck | Marginal Rate | % Kept |
|---|---|---|---|---|---|
| California | $8,000 | ~$5,260 | ~$202 | ~34.3% | ~65.7% |
| Texas | $8,000 | ~$5,780 | ~$222 | ~27.8% | ~72.2% |
| New York | $8,000 | ~$5,250 | ~$202 | ~34.4% | ~65.6% |
The Texas worker keeps roughly $520 more per year on the same gross raise. Across 10 years (with the same future growth rate), that gap compounds into several thousand dollars of after-tax income. State is one of the highest-leverage variables in a negotiation, especially when remote roles open the door to a cost-of-living arbitrage.
Negotiation Tactics That Maximize After-Tax Value
- Anchor on base, not bonus. Base salary compounds. A higher base means a higher next-year raise, a higher 401(k) match cap, and a higher bonus target if the company uses a percent-of-salary bonus plan. Signing bonuses are nice but they are one-time payments, usually withheld at the 22% federal flat rate. Use the bonus tax calculator to model the bonus side alone.
- Route part of the raise into 401(k). The pre-tax dollars escape federal and most state income tax (FICA still applies). If your marginal rate is 30%, every $1,000 routed into 401(k) costs you only about $700 in take-home and lands a full $1,000 in your account. The 401(k) contribution calculator shows the long-run effect.
- Watch the Social Security wage base. The 2026 wage base is $184,500. Income above that no longer pays the 6.2% Social Security tax, so a raise that crosses the cap keeps a higher percentage of each marginal dollar.
- Evaluate total comp, not headline salary. Equity vesting, sign-on bonus, relocation, 401(k) match, and health benefits can swing the after-tax value of an offer by 20% or more. Model the full offer in the job offer comparator.
- Run the multi-year math before accepting. The 5-year and 10-year cumulative gain in the calculator above is the real reward for negotiating today rather than next review cycle. Even a 3% smaller offer compounds into a meaningful gap over a decade.
Frequently Asked Questions
Common questions about salary negotiation calculator
How much of a raise do I actually keep after taxes?
Most workers keep 60-75% of a gross raise after federal income tax, state income tax, and FICA (Social Security plus Medicare). The exact share depends on your federal bracket, your state, and whether the raise crosses a bracket or the Social Security wage base. The calculator above shows your percent of raise kept based on your inputs. For a deeper bracket explainer, see the marginal vs. effective tax rate calculator.
Will a raise push me into a higher tax bracket and cost me money?
No. The US uses marginal brackets, so only the dollars above each threshold are taxed at the higher rate. Every dollar of your raise still adds to your take-home, just at the bracket rate that applies to that slice. Your net pay always rises when your gross rises.
What is the difference between marginal and effective tax rate on a raise?
The marginal rate is what applies to the next dollar (your raise). The effective rate is your average rate across all your income. When you negotiate, the marginal rate is the honest number, since it tells you exactly how much of the new dollars you keep. See the marginal vs. effective tax rate calculator for a side-by-side.
How do I know how much to ask for in a salary negotiation?
Pull market data from Levels.fyi, Glassdoor, PayScale, or Robert Half, then factor in your years of experience, location, and any cost-of-living delta. Plug a few candidate numbers into this calculator to compare after-tax outcomes, and compare full offers with the job offer comparator.
Should I negotiate base salary or a signing bonus?
Base salary compounds. Every future raise, 401(k) match, and bonus is usually a percentage of it. A signing bonus is a one-time supplemental payment and is often withheld at the 22% federal flat rate. To model the bonus side, use the bonus tax calculator.
How much is a 5%, 10%, or 20% raise worth after taxes in my state?
Use the calculator above with your real state, filing status, and salary. As a rough anchor, a 5% raise on $70,000 (single, California) is about $2,100 net per year; a 10% raise is about $4,200. No-income-tax states (TX, FL, WA, NV, SD, WY, AK, TN, NH) typically keep about 30% more of each raise dollar than high-tax states like California or New York.
Does putting my raise into a 401(k) change the math?
Yes. Pre-tax 401(k) contributions reduce your federal and (in most states) state taxable income, so each raise dollar routed into 401(k) avoids ordinary income tax. FICA is still owed on the contributed amount. The calculator lets you set a current and target 401(k) percent to model exactly that. See the 401(k) contribution calculator for longer-term projections.
Is this calculator's estimate accurate enough for negotiation prep?
Yes for directional planning. It uses 2026 federal brackets, 2026 state brackets and rates, the 2026 Social Security wage base, and the standard Medicare and Additional Medicare rates. It does not model city or local taxes, equity, benefits, credits, or deductions beyond pre-tax 401(k). Treat the result as an estimate, not tax advice.
