Job Offer Comparison Calculator — After-Tax Value

Put two offers side by side on what they are actually worth: after-tax pay in each state, plus employer-paid benefits and the retirement match that never show up in take-home pay. Estimate the total value rather than comparing headline salaries.

States: No state selected vs No state selected.

An estimate on federal and state withholding only. Cost of living, commute, equity vesting, and the actual cost of each health plan can outweigh everything shown here — particularly across a move. Bonuses are treated as ordinary wages for this comparison; a separately paid bonus is withheld at the supplemental rate instead.

🎓 Understand this tool

What it is

Two job offers side by side on after-tax value — cash, benefits, and retirement match — including offers in different states, which is where headline salaries mislead most.

How it works

Each offer runs through IRS Publication 15-T federal withholding and FICA, then through that state’s verified withholding pack. Employer-paid benefits and the retirement match are added back as real compensation even though they never appear in take-home pay, because ignoring them is how a worse offer wins on paper.

Getting the most from it

  1. Label each offer and enter base salary plus any expected bonus.
  2. Add the annual value of employer-paid benefits — Box 12 code DD on a current W-2 gives the health portion.
  3. Enter each retirement match as a percentage of salary.
  4. Set the state for each offer, then read the total-value row rather than the salary row.

Reading your result

The take-home line answers "what hits my account"; the total-value line answers "which offer is worth more". They frequently disagree, and the total-value line is usually the better guide for a decision.

What it can't tell you

Federal and state withholding only. Cost of living, commute, equity vesting schedules, and the real cost of each health plan can outweigh everything modelled here — especially across a move. Bonuses are treated as ordinary wages; a separately paid bonus is withheld at the supplemental rate.

Frequently asked questions

Compare after-tax pay rather than salary, because state income tax ranges from nothing to double digits. Enter each offer with its state and this estimates federal and state withholding for both, then adds benefits and the retirement match to give a total value.
