A mid-level software engineer in Austin, TX is comparing a $130,000 W-2 offer against their current $115,000 role. The new offer includes a $10,000 signing bonus and 0.1% equity in a Series B company.
Takeaway: Texas has no state income tax, which inflates take-home vs. the same offer in California (~9.3% marginal) or New York (~6.85%). Run the comparison with your state's rate above.
Take-home calculators estimate withholding based on single/married status and claimed allowances. If you have side income, multiple jobs, or itemized deductions, your actual withholding will differ. The IRS Tax Withholding Estimator is the most accurate tool for W-4 calibration.
Nine states have no income tax (TX, FL, WA, NV, AK, SD, WY, TN, NH). California tops out at 13.3% marginal. State tax can shift your net paycheck by $200-$1,000/month on a $100K salary. Always select your state before reading take-home results.
Cost of Living Salary AdjustmentEmployer-paid health insurance, 401(k) match, HSA contributions, and paid leave have real dollar value — typically $8,000-$25,000/year for a mid-career employee. Comparing two offers on base salary alone ignores a major component of total compensation.
Benefits Value CalculatorW-2 employees pay 7.65% FICA (SS + Medicare); employers match it invisibly. 1099 contractors pay the full 15.3% self-employment tax. A $100K 1099 contract has roughly $7,650 more tax friction than a $100K W-2 salary before any other adjustments.
1099 vs W-2 Tax ComparisonBonuses are withheld at a flat 22% federal supplemental rate (or 37% over $1M) — not your effective rate. Your actual tax on the bonus is determined at year-end filing. If your marginal rate is below 22%, you'll get a refund; above, you may owe.

Promotions typically come with a 10–20% salary increase. Moving up two levels or to management can yield 20–30% or more.
Yes! Many employers start with a low offer. Research the market rate for your new title and negotiate. Counter-offering is expected and professional.
Use tools like Glassdoor, Levels.fyi, or LinkedIn Salary to benchmark. If the offer is below market, come prepared with data to negotiate a higher number.
Not always. Some promotions include title changes without significant pay increases. Evaluate the full package including new responsibilities, growth potential, and benefits.
Multiply your current salary by the raise percentage divided by 100. A 15 percent promotion raise on a $70,000 salary adds $10,500 per year, or about $875 more per month before taxes.
Negotiate after receiving the promotion offer but before formally accepting. Have market data ready showing the typical pay range for your new role at comparable companies in your location.
A higher salary increases your 401k contributions if you maintain the same percentage. A $10,000 raise at 10 percent contribution adds $1,000 per year to retirement savings plus any employer match.
A merit raise rewards performance in your current role, typically 3 to 5 percent. A promotion raise compensates for increased responsibility in a new role, typically 10 to 20 percent or more.
Compare against the midpoint salary for your new title using Glassdoor, Payscale, or LinkedIn Salary. If the offer places you below the 25th percentile for the role, you have strong grounds to negotiate higher.
Consider the long-term career value. A title upgrade can lead to higher-paying opportunities elsewhere. However, negotiate for a future salary review within 3 to 6 months tied to specific performance goals.
New Salary = Current Salary × (1 + Raise%)
Total Comp = Base Salary + (Salary × Bonus%)
