See who’s paying it in St. PetersburgAn 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. Check real listings and a tax professional before you decide anything.

Four things move between Seattle and St. Petersburg, and they do not move together. Pay is the largest of them here: worth $1,759 a month against you.
The shape is the familiar one — smaller offer, cheaper rent — and here it does not come out. Pay drops $2,500 a month gross; rent gives back $450. The rest is the gap.
Neither Washington nor Florida taxes income. That takes the loudest argument for this move off the table before it starts — this one is decided by rent and by what the job pays, and by nothing else on your payslip.
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. Seattle and St. Petersburg may both charge you something local that is not counted here.
A one-bedroom runs about $1,700 in St. Petersburg against $2,150 in Seattle — $450 a month, $5,400 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 28% less in St. Petersburg: $76,000 against $106,000. 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 $106,000 this page opens on is a typical salary for Seattle 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 2,530 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 Washington and Florida. 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. Petersburg has to pay $99,000 a year to leave you exactly what Seattle leaves you now, at $1,700 rent. The typical offer there is $76,000, so the gap is $23,000.
That is a number to take into a conversation, not a reason to stop. It is also usually smaller than it looks: $23,000 on a $76,000 base is a 30% ask, and the difference between two offers in the same city is routinely wider than that.
The number to beat
$99,000a year
What St. Petersburg has to pay before the move stops costing you money. The typical offer is $76,000, so there is $23,000 to find — and somebody in St. Petersburg is paying it.
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.
