| Line | Chicago, $95,000 | San Francisco, $120,000 |
|---|---|---|
| Federal income tax | $12,070 | $17,570 |
| State income tax | $4,703 (IL flat 4.95%) | $7,204 (CA progressive) |
| FICA (Social Security + Medicare) | $7,268 | $9,180 |
| Take-home per year | $70,960 | $86,046 |
| Take-home per month | ~$5,913 | ~$7,170 |
Illinois charges a flat 4.95% with no local income tax, which makes Chicago unusually predictable. California layers progressive brackets from 1% to 12.3%, so the state slice grows faster than your salary does — the gap between the two states is $2,501 on this comparison alone.
The $25,000 gross difference between the offers shrinks to $15,086 after tax. That is the first thing most offer comparisons miss: you never compare gross to gross. Then housing takes the rest.
| Monthly item | Chicago | San Francisco |
|---|---|---|
| Take-home | ~$5,913 | ~$7,170 |
| 1-bedroom rent (typical) | ~$1,900 | ~$3,400 |
| Left for everything else | ~$4,013 | ~$3,770 |
Chicago leaves about $243 more per month for food, transport, savings and debt. Over a year that is roughly $2,900 — enough to fund a Roth IRA contribution.
Enter each gross salary in the calculator, pick the state, and compare take-home minus your real rent. If the difference is under about $300 a month, the lifestyle factors (commute, family, weather, career path) should decide.
At $95,000, each extra $1,000 of wages costs about $220 in federal tax (22% marginal bracket) plus roughly $76 in FICA — you keep about $704 of it. Enter any salary in the calculator to see your own split; the donut shows exactly which slice grows with each raise.
On $95,000 single, federal tax is $12,070 — an effective federal rate of 12.7%. That is well below the 22% marginal rate, because lower slices of income are taxed at 10% and 12%. The rest of the gap between gross and take-home is FICA plus any state tax.
Figures use 2026 federal brackets after the $16,100 standard deduction (single filer), Social Security at 6.2% to the $184,500 wage base, and Medicare at 1.45%. State amounts come from simplified planning tables. Real paychecks also reflect pre-tax benefits, local taxes and credits — treat every number here as a planning estimate, not tax advice.
On take-home minus typical rent, yes — by roughly $240 a month. If your San Francisco rent is below about $3,000, the higher salary starts to win.
Illinois takes $4,702 at the flat 4.95% rate (no local income tax). California would take $5,344 on a $100,000 salary and $7,204 on $120,000.
Federal tax ($17,570), California state tax ($7,204) and FICA ($9,180) total $33,954 — about 28% of gross pay.
No. The estimate excludes city taxes, credits and itemised deductions. It is a planning estimate, not tax advice.
A common rule is 30% of take-home, which is about $1,770 a month — slightly below the typical one-bedroom, so many renters share or move a neighbourhood out.
