The offer with the bigger number on the letter often isn't the one that puts more in your bank account. Choosing between job offers on salary alone can cost you tens of thousands of dollars over a few years. An offer comparison calculator that models taxes, equity vesting, and cost of living gives you a real after-tax job offer comparison and a 4-year total compensation comparison—so you can compare job offers like a pro.

Use our job offer comparison tool above: enter both offers, then read on to interpret the results and understand total compensation, state taxes, and negotiation.

How to Compare Job Offers the Right Way

Comparing job offers the right way means looking at total compensation, not just base salary. A higher base in a high-tax state with expensive housing can leave you with less spending power than a lower base elsewhere. Use this total compensation calculator to run both offers with your real numbers.

  • Base salary isn't everything. Bonus, equity, 401k match, and benefits can add 20–50%+ to your real comp. A $150k base with a 10% bonus and $60k RSUs over 4 years is very different from $150k cash-only.
  • Equity timing matters. RSUs that vest over 4 years hit your taxable income each year. A front-loaded vest can mean higher taxes early; a back-loaded one shifts value (and risk) to later. Our RSU Tax Calculator shows tax at vest.
  • Taxes reduce real value. Federal income tax (marginal brackets plus standard deduction), state income tax (0% in Texas/Florida/Washington to 13%+ in California), and FICA (7.65% up to the wage base, then Medicare on the rest) can take 25–45% of gross. On the same $150,000 salary, California often nets about $102,000 after federal, state, and FICA while Texas nets about $114,000—roughly $12,000 more per year with no state income tax. After-tax job offer comparison is what you should optimize for.
  • Cost of living changes everything. A $180,000 offer in San Francisco may be worth less than $150,000 in Austin after taxes and housing costs. Use our Relocation Salary Calculator to compare cities.

Real example: At identical $150,000 cash pay, California take-home is about $102k and Texas about $114k after federal, state, and FICA. Layer on San Francisco’s cost-of-living index (~165 vs Austin ~98) and the purchasing-power gap widens further. Run both offers in the calculator above with your filing status, health costs, and city COL to see your exact 4-year total compensation comparison.

Key Components of Total Compensation

A job offer evaluation checklist should include every element that affects your wallet. Tech and finance roles often mix base, bonus, and equity—so a tech job offer comparison, RSU offer comparison, or RSU vs salary comparison needs all of these in one place.

  • Base salary: Guaranteed cash; taxed as ordinary income. Use a state paycheck calculator for a single offer.
  • Bonus: Often taxed at a flat supplemental rate. Use our Bonus Tax Calculator to see net bonus.
  • RSUs / equity: Usually vest over 4 years; taxed as income when they vest. Include the full 4-year grant value in this tool and use Equity Vesting Calculator for schedule.
  • 401k match: Part of total comp but tax-deferred; it doesn't show up in take-home. Still valuable—model it in the calculator.
  • PTO value: Each vacation day is worth roughly your daily salary (annual base ÷ 260 working days). An offer with 25 PTO days vs 15 days at $150k adds ~$5,760 in annual value. Enter PTO days for each offer—we compute this automatically.
  • Commute cost: Gas, transit passes, and parking can easily run $3,000–$8,000/year. A fully-remote offer vs. one requiring 5 days/week in office can differ by $12,000–$32,000 over 4 years—real money that never shows up in the offer letter. Enter your annual commute cost; we subtract it from total comp.
  • Health premium: Your out-of-pocket cost (employee share of premiums). A $3k/year difference is $12k over 4 years. We also model HSA and commuter benefits.

After-Tax Job Offer Comparison

Gross numbers are misleading. Two offers that look similar on paper—e.g. $160k base + $80k equity—can diverge by $8k–$15k per year in take-home once you apply federal tax, state tax, and FICA. This offer comparison calculator does an after-tax job offer comparison for you: it uses 2026 federal brackets, standard deduction, state tax by state, and your filing status to estimate net pay each year and over 4 years.

What actually moves the needle:

  • State: 0% in no-tax states vs 6–10%+ effective in high-tax states on six-figure income.
  • Filing status: Married filing jointly typically has a lower effective rate than single at the same income.
  • Bonus vs salary: Supplemental pay (bonus, sign-on) is often withheld at a flat 22% federal (or 37% above $1M); it's still taxed as ordinary income at year-end.
  • Equity vests: RSUs are taxed as ordinary income when they vest (W-2 income), not as capital gains—so they stack on top of salary and can push you into a higher bracket that year.

Run both offers in the tool above to see side-by-side take-home and break-even year.

Comparing Job Offers in Different States

Comparing job offers in different states is one of the highest-impact uses of a job offer comparison tool. State income tax ranges from 0% (Texas, Florida, Washington, Nevada, etc.) to over 13% top rate in California (effective rates on $150k are often 6–8% in CA). On a $150k salary, that's often $9k–$12k more in your pocket per year in a no-tax state—and the gap grows with bonus and equity.

Set each offer's state in the calculator to see the difference. For cost-of-living by city (rent, groceries, etc.), use our Relocation Salary Calculator so you factor in both tax and COL.

4-Year Total Compensation Breakdown

Tech offers often quote equity as a 4-year grant. A 4-year total compensation comparison sums base + bonus + vested equity + 401k match (and other benefits you value) over four years, then applies taxes year by year. That tells you which offer actually puts more money in your pocket over the typical vest period.

Our total compensation calculator assumes 25% vest per year (standard 4-year schedule). Each year's vest is added to your taxable income, so your effective tax rate can rise in high-vest years. You can add equity growth (e.g. 0% for conservative, 5–10% for optimistic). Break-even is the first year when one offer's cumulative take-home passes the other—useful when one offer has more equity back-loaded.

Real Example: Comparing Two Tech Job Offers

Offer A (San Francisco) vs Offer B (Austin)
Single filer, 2026 federal and state rates. Health premium $2,400/year each. Numbers are illustrative for a typical tech job offer comparison or RSU offer comparison.

~Year 1 take-home (est.)~$143,000~$143,000
~4-year take-home (est.)~$573,000~$573,000
Tax-only (no COL): Offer A’s higher cash and equity nearly offset California state tax—Year 1 and 4-year take-home are essentially a wash (~$143k / ~$573k each), while Offer A still leads on total-comp value once 401(k) match is included. Apply city COL (SF ~165, Austin ~98) in the calculator and Offer B typically wins on purchasing power. Enter your exact numbers above for a precise after-tax job offer comparison.

How to Negotiate a Better Job Offer

Use this offer comparison calculator to run scenarios before and during negotiation. When you have numbers, you negotiate from strength: if one offer has lower base but no state tax, show the take-home comparison—sometimes the "lower" offer already wins, and you can ask the other side to close the gap. If equity vests slowly, use the break-even view to ask for a higher sign-on or more RSUs upfront.

  • Ask for more base, more equity, or a sign-on to close the gap you see in the 4-year total.
  • Use our Bonus Tax Calculator to see the net value of a sign-on so you can compare it to extra salary (sign-on is often taxed at 22% federal withholding).
  • If you're comparing job offers in different states, get the other side to acknowledge COL and tax—then ask for a bump or remote flexibility.

Common Mistakes When Comparing Offers

A few slip-ups can make the wrong offer look better. Avoid these when you run your job offer comparison:

  • Ignoring state tax. A $10k difference in state tax is $10k less in your pocket every year—and that compounds over 4 years.
  • Comparing only base salary. Total comp includes bonus, RSUs, and 401k match. Use a total compensation calculator so nothing is left off the table.
  • Treating RSUs as guaranteed. Stock can go down. Model with 0% growth for a conservative view; add growth only for upside scenarios.
  • Skipping cost of living. Use the calculator's COL field and the Relocation Salary Calculator so you compare real purchasing power, not just dollar take-home.
  • Forgetting health premium. A $3k/year difference in out-of-pocket cost is $12k over 4 years—real money that doesn't show up in the offer letter.
  • Ignoring PTO days. An extra 10 vacation days at a $150k salary is worth ~$5,760/year in value. Over a 4-year period that's $23k. Enter PTO days for each offer—the calculator converts them to dollar value automatically.
  • Overlooking commute costs. Five days/week in office at $20/day round-trip is $5,200/year. A fully-remote offer vs. in-office can differ by $20k+ over 4 years before you factor in time. Enter annual commute cost to subtract it from real take-home.

The 22% flat supplemental withholding trap: why RSU vests and bonuses under-withhold federal tax for anyone in the 24%, 32%, or higher bracket — and the April surprise it creates

Source: IRS Publication 15 (2026), Section 7 — Supplemental Wages; P.L. 119-21 (OBBBA); Treas. Reg. §31.3402(g)-1

When an employer pays you a bonus or vests RSUs, they are required to withhold federal income tax at the flat 22% supplemental wage rate (IRS Publication 15, Section 7) — up to $1 million in cumulative supplemental wages per employer per year. Above $1 million, the rate jumps to 37%. This flat rate is an administrative shortcut: it is a withholding rate, not a tax rate. Your actual tax owed depends on your marginal bracket.

Over $626,35037%37% (>$1M rule)~0% (mandatory 37% kicks in)~$0

Real-world example: comparing two offers with heavy equity

Offer A: $175,000 salary + $30,000/year RSU vest (single filer). Combined income = $205,000 → 32% bracket. RSU federal withholding = 22% ($6,600); actual federal owed = 32% ($9,600) → $3,000 surprise balance due per vest. Plus state tax shortfall — California's supplemental rate is 10.23%; actual effective CA rate may be higher. Total shortfall could be $4,000–$5,000 per vest.

Offer B: $185,000 salary + $15,000/year RSU vest. Lower vest amount means smaller shortfall. The gross-to-net difference between these two offers is even larger than the headline numbers suggest.

How to prevent the underpayment surprise

  • Adjust your W-4: submit a new Form W-4 with additional withholding in Box 4(c) equal to the estimated shortfall
  • Pay quarterly estimated taxes (Form 1040-ES) — especially when RSU vest creates a large single-quarter income spike
  • Safe harbor rule: avoid the underpayment penalty by paying 100% of prior-year tax liability (110% if prior AGI exceeded $150k) — pay this regardless of projected shortfall
  • Coordinate timing: if spouse also has W-2 income, combined bracket may be higher than individual calculation suggests

Implication for offer comparison

Two offers with identical gross compensation can produce different true after-tax take-home if one has a larger equity component — because larger equity means a larger tax shortfall that must be paid in April. The calculator above models this correctly using marginal brackets; the offer letter comparison does not.

401(k) vesting schedules: ERISA's 3-year cliff and 6-year graded minimums, the 2026 contribution limits, and the golden handcuff math every job-hopper should run

Source: IRC §411(a)(2)(B); IRS Issue Snapshot — Vesting Schedules for Matching Contributions; IRS Notice 2025-67 (2026 limits); PSCA 68th Annual Survey (2025)

The dollar value of an employer's 401(k) match depends critically on the vesting schedule — a variable that never appears in the offer letter headline. Under ERISA (IRC §411(a)(2)(B)), employer matching contributions must follow at minimum a 3-year cliff or 6-year graded vesting schedule. Your own elective deferrals are always 100% immediately vested by law.

The golden handcuff math: running the numbers before you switch

Example: You've been at Company A for 2 years and 3 months. The 401(k) plan uses a 3-year cliff. Your employer has contributed $9,500 in matching contributions over those 2+ years ($4,500/year average). Under the cliff schedule, you own 0% of that match today. If you leave now, you forfeit all $9,500. Add to this unvested RSUs (covered below), and your real switching cost could exceed the first year's apparent salary increase from the new offer.

Key questions to ask when evaluating a new 401(k): Does the new employer offer immediate vesting? If they use a cliff schedule, how long until you fully vest? Does the new employer match more than the old one, or less? Is there a SIMPLE 401(k) or Safe Harbor plan (which must vest immediately)?

The unvested equity at your current employer: how to calculate the full cost of switching jobs, negotiate a make-whole sign-on, and use quarterly vest timing to maximize retention

Source: IRS Publication 15 (2026) §7; ASC 718; typical RSU grant agreement provisions

A common and costly mistake: comparing only the new offer vs. your current salary. You also need to subtract what you'd forfeit by leaving — primarily unvested RSUs and unvested 401(k) employer match. This number can be $50,000–$150,000 or more for mid-to-senior tech employees and it changes the offer comparison dramatically.

True switching cost calculation

1Unvested RSUs: (unvested share count × current FMV). This is what you forfeit on your last day.
2Unvested 401(k) match: check your statement's "vested balance" vs. "total balance". The difference is forfeit.
3Unvested sign-on clawback: many sign-ons require repayment if you leave within 1–2 years. Check your offer letter for any clawback provision.
4Total switching cost = (1) + (2) + (3). Subtract this from the new offer's Year-1 value to see your true net gain.

Quarterly vest timing: wait for the vest date

Most tech RSU grants vest quarterly (1/16 per quarter for a standard 4-year grant). If your next vest is 6 weeks away and worth $20,000, waiting 6 weeks before tendering your resignation could preserve that full grant. This costs you nothing except time. Confirm the exact vest date in your brokerage account or Carta, and cross-reference with your resignation notice period.

Caution: if your current employer has a cliff (annual or 1-year initial cliff before quarterly vesting begins), missing the cliff by even one day means forfeiting that entire cliff tranche.

Negotiating a make-whole sign-on payment

Standard practice in tech recruiting: ask the new employer to "make you whole" on unvested equity you're leaving. Present the number clearly — e.g., "I have $80,000 in unvested RSUs vesting over the next 18 months; I need a sign-on that covers this."

Make-whole tax math (the gross-up problem)

A sign-on bonus is taxed as supplemental income at 22% federal + state. To net $80,000, the gross sign-on must be approximately:

At 24% federal + 6% state~$115,000 gross
At 32% federal + 9% state (e.g. CA)~$135,000 gross
At 35% federal + 13% state (top CA)~$148,000 gross

Ask the recruiter whether the company will gross up the sign-on (i.e., cover your tax on it). Some FAANG employers do; most do not. If they won't gross up, request the higher gross amount directly.

Double-trigger vs. single-trigger RSU acceleration

Review your RSU grant agreement before switching. Double-trigger acceleration (most common at FAANG and large tech) requires both a change of control AND termination — meaning your unvested RSUs may vest if your current employer is acquired and you're laid off. Single-trigger (rarer) accelerates vesting on the change of control alone. If your current employer is a potential acquisition target, this clause could be worth significant money and should factor into your switching timing.

Offer comparison FAQs

After-tax pay, equity risk, benefits, state taxes, switching costs, and negotiation

Enter both offers with base salary, bonus, total four-year equity, 401(k) match, state, health premium, and PTO. The calculator compares annual take-home, four-year total value, taxes, benefits, purchasing power, and break-even timing.

It compares what each offer actually leaves after federal income tax, state income tax, Social Security, Medicare, and health premiums. Offers with similar gross pay can differ by $10,000 or more per year because of location and compensation structure.

The initial equity grant is modeled as vesting 25% per year across four years and each vest is taxed as ordinary income. Advanced options let you model stock growth and refresh grants. Use 0% growth for a conservative baseline.

Salary is guaranteed cash; RSUs depend on vesting, continued employment, and stock price. Compare both, but discount uncertain private-company or volatile equity. A conservative decision usually uses 0% stock growth and separately checks a bear case.

PTO value is estimated as annual base salary divided by 260 working days, multiplied by PTO days. Ten extra days at a $150,000 salary are worth about $5,769 per year. This is an economic value, not extra cash paid to you.

Break-even is the first year when cumulative take-home from Offer A exceeds Offer B. It helps when one package has stronger early cash while another has back-loaded equity or later refresh grants.

Technology equity grants commonly vest over four years. Looking only at Year 1 can overvalue a sign-on bonus or hide back-loaded equity. A four-year view captures salary, bonus, vesting, benefits, taxes, and recurring costs across the normal grant cycle.

State income tax ranges from 0% in states such as Texas, Florida, Nevada, and Washington to high effective rates in states such as California and New York. A lower gross offer in a no-income-tax state can produce more take-home.

Select each city to populate its cost-of-living index, then compare tax-adjusted purchasing power. Housing, commuting, and childcare can overwhelm a salary difference, so use the Relocation Salary Calculator for a deeper city-to-city analysis.

Include base salary, target bonus, equity value and vesting, 401(k) match and vesting schedule, health premiums, HSA contributions, PTO, ESPP, sign-on, relocation, commute costs, state tax, cost of living, remote-work policy, and any clawbacks.

Use the negotiation simulator to add base salary or equity to either offer and see the four-year after-tax impact instantly. Ask for the component that closes the actual gap—base, sign-on, equity, or a make-whole payment—not just the largest headline number.

Employers often withhold federal supplemental wages at 22%, but your actual marginal rate may be 24%, 32%, 35%, or 37%. The shortfall is settled on your tax return. High-equity offers may therefore need extra W-4 withholding or quarterly estimated payments.

Your own contributions are always yours, but employer matching funds may vest over time. If a plan uses a three-year cliff and you leave earlier, the apparent match may be worth $0. Ask the recruiter for the exact vesting schedule before valuing the benefit.

Estimate unvested shares times current share value, then add unvested employer match and any bonus clawback. Treat that total as a switching cost and ask the new employer for a make-whole sign-on or replacement equity.

Use caution. Preferred financing price, common-stock 409A value, and eventual employee proceeds are not the same. Apply a meaningful risk discount, consider dilution and liquidity, and compare a cash-only or zero-equity scenario before deciding.

Yes. Add them under advanced options. They are included in Year 1 and taxed as compensation. Check the offer letter for repayment clauses—many require repayment if you leave within 12 or 24 months.

No. It models the major financial components, but cannot price management quality, role scope, promotion odds, work-life balance, job security, healthcare plan details, or career growth. Use the result as a financial scorecard, not the entire decision.
