See who’s paying it in St. LouisAn estimate, not advice. Single filer, standard deduction, 2026federal brackets and 7.65% payroll; state rates are approximate effective rates. Rents are HUD Fair Market Rents for a one-bedroom (FY2026) — the 40th percentile of gross rent, utilities included — and pay is scaled by each metro’s all-occupations mean wage from the BLS (OEWS, May 2025). Both are measured for the whole metro, not your neighbourhood or your job. Your actual position depends on your filing status, deductions, benefits and local taxes.

Four things move between San Francisco and St. Louis, and they do not move together. Pay is the largest of them here: worth $2,286 a month against you.
That is the trade nobody prices properly. The offer is smaller — $76,000 against $115,000 — and the instinct is to read that as a step backwards. Rent falling by $1,975 a month is a raise that never appears on the offer letter.
Missouri charges 4.7% against California’s 6%. On these two salaries that is $277 a month in your favour — real, and smaller than the gap between the two rates makes it sound, because the salary shrinks at the same time.
Those are approximate effective rates for a single filer on a middle income in 2026, not top brackets, and they ignore city and county taxes. San Francisco and St. Louis may both charge you something local that is not counted here.
A one-bedroom runs about $1,000 in St. Louis against $2,975 in San Francisco — $1,975 a month, $23,700 a year. Rent is the largest thing you can actually change by moving, and it is why the smaller offer can still be the better one.
Both figures are HUD Fair Market Rents for a one-bedroom, FY2026 — the 40th percentile of gross rent with utilities in it, so four in ten one-bedrooms in each metro go for less. They are measured across the whole metro, which means a suburb carries its metro's number. A search on any listings site for the neighbourhoods you would actually live in will still beat them, and it takes ten minutes.
The same work pays about 34% less in St. Louis: $76,000 against $115,000. That is not a negotiating failure, it is the local market — and it is the number most people leave out when they picture the move, because rent is easy to look up and salary bands are not.
Both figures are bands, not offers: a salary scaled by each metro's all-occupations mean wage from the BLS, May 2025. That measures every job in the metro rather than yours, so it tells you what the local market pays in general, not what you would be offered. The $115,000 this page opens on is a typical salary for San Francisco and it is almost certainly not yours — put your own into the calculator above and the whole comparison re-runs on it.
It is about 1,740 miles between them. Nothing above counts what the move itself costs: the truck, the deposit, the overlap in rent, the weeks between the last paycheque and the first one.
Nor does it count sales tax, property tax, car insurance, utilities, childcare or health cover, all of which move between California and Missouri. The figures here are federal tax, payroll, state income tax and rent — the four that decide most of it, and the four that can be computed rather than guessed.
St. Louis needs to pay $77,000 a year for you to come out exactly level, and the typical offer is $76,000. On the money this is a coin toss, which is worth knowing — it means you get to decide it on everything else.
Anything above $77,000 is the move paying for itself. Below it, you are buying something else with the difference, and it is worth being able to name what.

An estimate, not advice. Single filer, standard deduction, 2026 federal brackets and 7.65% payroll; state rates are approximate effective rates and rents are typical one-bedroom asking prices. Salary bands are scaled from a national baseline by what the same job tends to pay in each metro. Your actual position depends on your filing status, deductions, benefits and local taxes. Check real listings and a tax professional before you decide anything.
